Subject: [PATCH 1/4] fix: rename the upstream lock so it does not collide with
 upstream/

UPSTREAM and the upstream/ directory differ only by case, so a fresh clone on
a case-insensitive filesystem (default macOS and Windows) cannot hold both:
git reports UPSTREAM as deleted and build fails with IsADirectoryError.

Rename the lock to UPSTREAM.lock (content unchanged) and update its readers.
Add a test that fails when two tracked paths, including directory prefixes,
differ only by case, and a macOS CI job that checks the checkout is complete.
The macOS job also surfaced a temp-path comparison in test_runtime.py that
failed on macOS before this change (/var is a symlink to /private/var); the
test now resolves its temp root.

Both values mean the same thing, and neither is a model slug. For a panel role the value is a list, and one subagent runs per entry, so the list length sets the panel size.

 That's a Bug fix prompt. "repro first" is a real constraint, not politeness, and the playbook honors it. Watch the todo list fill with the Bug fix steps. A skipped step stays visible with `skip: <reason>`.
 
+## What goes in a prompt
+
+A useful prompt carries up to five things, and each one fits in a sentence:
+
+- **The goal.** Say what's wrong, or what you want.
+- **The done check.** It must be able to pass or fail. "Make it better" and "work on it for an hour" aren't checks.
+- **The proof you want to see.** Ask for the real command output, a video of the flow, the stored value, or a before-and-after number.
+- **What you already know.** A symptom, a repro step, a log line, or a link saves the agent a search.
+- **The real constraints.** "repro first", "don't change any code yet", "zero behavior change", and "let me review before proceeding" each change what the agent does.
+
+Here's one prompt with all five:
+
+```text
+/poteto-mode the csv export drops its last row since yesterday's deploy. failing job id is 4812. repro first, then fix. done means the 60k-row fixture exports every row. show me the row counts before and after.
+```
+
+Two things are worth leaving out:
+
+- **The how.** Say what to achieve, and leave the agent room to find a better path than the one you'd pick. The same goes for a list of skills, covered in the pitfall below.
+- **Your theory of the cause, at first.** A stated guess narrows the search to wherever you pointed. Let the agent restate the problem before you share your hunch.
+
+For a noisy report, such as a long thread or a vague bug, make the restatement the first step:
+
+```text
+/poteto-mode read this thread. restate the underlying issue in your own words, in plain english. don't change any code yet.
+```
+
+A misreading shows up in the restatement, before any code exists. Correct it there, and it costs you one message instead of one wrong fix. For the restatement alone, with no playbook, run [`/in-your-own-words`](../../skills/in-your-own-words/SKILL.md). It restates what the agent thinks your goals are and what problem you're trying to solve.
+
+When you're unsure whether a prompt is aimed right, run [`/sharpen`](../../skills/sharpen/SKILL.md) on it before you send it:
+
+```text
+/sharpen write a migration guide for the v2 config format.
+```
+
+The agent says what a top professional would do that you didn't ask for, the rawest material they would start from, the methods and tools they would use, and what other than you or the agent would show the result is right. Then it rewrites your prompt to ask for exactly that, deeper but not bigger, and leaves your choices open. It doesn't do the task. Read the rewrite, then send it, for example with `/poteto-mode`.

+The [Prototype playbook](../../skills/poteto-mode/playbooks/prototype.md) builds throwaway sketches in a scratch directory, puts the variants behind one switcher, drives each one, and captures screenshots or timings. It also works for behavior and algorithms, not just UI. Prototypes are planning with code. They let the agent answer its own open questions by running something instead of asking you, and they leave room for an option you wouldn't have thought of.
+
+The same idea scales up to a real design. Pair `/architect` with prototypes and keep a review gate:
+
+```text
+/poteto-mode we need rate limiting for external webhooks. /architect it first, and answer open questions with prototypes. let me review before proceeding.
+```
+
+Don't spend reviewers on an abstract plan. `/interrogate` belongs on a diff. Point adversarial review at a plan with no code behind it and the reviewers invent theoretical risks and edge cases that will never happen. Let prototypes settle the questions, then review what got built.
+
+## Write the README first for shared code
+
+For a package or API that other code will use, start with the doc a user would read:
+
+```text
+/poteto-mode write a tutorial for how i would use the new config package first. then /teach me why it beats the current one.
+```
+
+Writing the tutorial first forces the caller's view. You describe the API to a hypothetical user and work back to the implementation. The doc also becomes a concrete target the agent checks its own work against. Name [`/technical-writing`](../../skills/technical-writing/SKILL.md) when the doc itself matters, so a tutorial stays a tutorial instead of drifting into reference and explanation at once.
+
+## Plan after the design settles
+
+pstack has no planning skill, on purpose. When you do want a written plan, ask for it once the design is settled:
+
+```text
+/poteto-mode turn this design into a plan. small verifiable PRs, each with its own verification steps.
+```
+
+The [Multi-phase plan playbook](../../skills/poteto-mode/playbooks/multi-phase-plan.md) settles any remaining open questions by prototype, then writes one section per PR, each ending in proof that the change works. A passing test suite alone doesn't count as that proof. The plan is the deliverable. The playbook doesn't implement it, and it names which execution playbook should run it next.
+
+For a migration, state the bar in the prompt:
+
+```text
+/poteto-mode plan the migration of our ui library to the new styling system. small verifiable PRs, each with visual regression checks. the result must match the original exactly, bugs included.
+```
+
+"bugs included" keeps the migration from quietly fixing things on the way, which would make the old and new output impossible to compare. For a project that spans many days, you can commit the plan to the repo for a while so other agents see the work in progress. Delete it when the work lands.

 ## How much design work does a task deserve?

 - A change that crosses function boundaries or moves ownership earns `/architect`, which brings `/arena` with it.
 - A standalone decision where independent attempts would help, like naming, formats, or an algorithm, is `/arena` directly.
 - A coverage matrix, set of parallel checks, or race with declared arms is `/swarm`.
+- An open question you could answer by running something, like a layout, a timing, or an approach, gets a prototype, not a debate.
 - A contested design that's expensive to reverse gets `/architect`, then `/interrogate` before shipping.

 `/poteto-mode` already applies this ladder. Boundary-crossing work triggers `/architect` on its own, so you reach for these directly mainly when you want more or less scrutiny than the default.

Agents spend fewer tokens, and every run becomes repeatable. A CLI that agents use well has these traits:
 
-Once the verify skill works, a [`/swarm`](../../skills/swarm/SKILL.md) can split a full pass by feature-map entry and aggregate the results.

+## Prove a property with a formal verification skill
+
+A verification skill proves the paths you drive. Some bugs live on paths nobody drives: two retries that overlap, a lock that expires mid-write, a state change that arrives out of order. Tests rarely reach those cases. For code where such a bug is costly, run:
+
+```text
+/create-formal-verification-skill
+```
+
+[`/create-formal-verification-skill`](../../skills/create-formal-verification-skill/SKILL.md) picks the target from the code: a promise the code makes, where a break harms users and tests rarely reach the case that breaks it.

+
+```text
+/create-formal-verification-skill the job lease and retry logic. a job must never run twice at once.
+```
+
+The question picks the tool. Whether events can happen in a bad order suits a model checker over a small model of the design, and TLA+ is the default for that in any language. Whether the code behaves for every input suits a verifier that runs on the code. If no verifier runs on your language, the agent says so and tests the real code with generated inputs, not a hand-written model of the function. A property that must hold at every size can need a proof. The agent tells you which tool it chose and why.
+
+It verifies one property and shows that property failing on a broken variant of the code, because a check you've never seen fail proves nothing. When the current code already breaks the property, you get the counterexample as a short sequence of steps in your code's terms. The property stays as stated, so the finding stays a finding. Product code doesn't change unless you ask.
+
+It writes a project-local skill that tells the next agent whether a change touches the verified code, how to run the check with one command, and how to tell a real bug from a modeling error. Before handing it over, the generator follows that skill once on a scratch change that breaks the property, and the check must catch it. The handoff says what was verified, with which tool and bounds, what the check found, and what it doesn't cover. A pass covers the model or the bound, not the whole system.
+
+The skill also records which code each check covers and the commit where the check last matched it. Merges and refactors that skip the skill can leave the check passing on a description of code that's gone. After them, run [`/maintain-formal-verification-skill`](../../skills/maintain-formal-verification-skill/SKILL.md). It updates the verification from the code, reruns it, shows that each updated check can still fail, and tells you whether each failure is drift in the verification or a bug in the code.

+A [Cursor Project](https://cursor.com/blog/projects) gives one coordinator agent a persistent thread. The coordinator doesn't write code.

+- Drag related chats into the Project, finished ones included. They become context for every agent in it.

+## Let loops start themselves

+Every loop above still waits for you to start it. A scheduled or event-driven automation removes that step. Software maintenance splits into stages that suit this well: triage a report, reproduce it, fix it, verify the fix. Two rules keep such a line trustworthy:
+
+- Every stage can stop the line. Triage can decide the report is expected behavior, repro can fail to reproduce it, and the fixer can judge the change too risky. Each of those outcomes is useful, because it keeps bad work from reaching the next stage, where it costs more to undo.
+- Every stage hands over evidence. Repro attaches screenshots and video of the broken state, and the fix attaches before-and-after proof. A human can then check that the agent fixed the right thing before reading a line of code.

+pstack ships this as a dormant [automation pack](../../automations/benny/README.md) for Slack issue reports. One automation triages each report. The other reproduces confirmed bugs and may prepare a small draft fix. Point an agent at its [`FOR_AGENTS.md`](../../automations/benny/FOR_AGENTS.md) and name the target repository to set it up.

 **Pitfall:** a duration is not a finish condition. "work on this for 4 hours" gives the agent nothing to check, and you'll wake up to four hours of motion instead of a result. Give `/loop` a predicate that can pass or fail.

Approve a proposal only if it would change a future decision. One weird session is an anecdote, not a rule.
 
+## Fix the environment with `/correct`
+
+When you correct agents for the same mistake again and again, the fix belongs in the repo, not in your next prompt. Rank the options by how well they hold:
+
+1. Make the mistake impossible with architecture or a better data structure.
+2. Block it with types, or with a lint or CI check whose error names the fix.
+3. Catch it with a test.
+4. Write it down as a doc or agent rule. Nothing fails when an agent skips a rule, so this comes last.
+
+Human review isn't on the list. A reviewer who must catch the same mistake on every PR is the problem this fixes. [`/correct`](../../skills/correct/SKILL.md) does the work:
+
+```text
+/correct agents keep calling the database client directly instead of going through the repository layer
+```
+
+It reads recent commits, reverts, review comments, and comments that explain workarounds, then groups the mistakes into classes. A class counts once it has happened twice. It fixes the most frequent classes one commit each, at the highest level that works, and proves each new check fails on a real past mistake. It also keeps a table in the agent instruction file that pairs each rule with what enforces it, so a rule that nothing enforces shows up as a repeat. The reply lists each class with its evidence, the level chosen, and why a higher level didn't work.
+
+Run it with no argument and it finds the classes from history on its own. `/reflect` and `/correct` split the work. `/reflect` improves skills from one session. `/correct` changes the repo so a mistake class can't come back.

+Asking for the eval up front keeps the edit honest. A fix written from one bad session tends to overfit that session, and over many edits the skill drifts. The eval catches the drift before it ships.
+
 The [Eval playbook](../../skills/poteto-mode/playbooks/eval.md) is built around one failure mode, the observer effect. An agent that knows it's being evaluated behaves differently. So candidate agents get an organic-looking task in sanitized directories, never the words "eval" or "candidate", and never each other's existence. One judge scores all outputs under neutral labels, and chain-following gets graded from which files each candidate actually read, not from what it claims.
 
 Read every output yourself before accepting the verdict. If you disagree with the judge, suspect the rubric before you suspect your judgment.

 - **Enumerating skills in the prompt.** "use /how then /architect then /arena" reorders steps the playbook already sequences. State the goal and constraints. Name a skill only to override a default.
 - **A vague finish condition.** "make it better" gives `/loop` nothing to check. Give a command or artifact that can pass or fail.
-- **Parallel agents in one worktree.** They overwrite each other and the diff becomes archaeology. Say "own worktree per attempt" and the isolation is free.
+- **Leading with your theory of the cause.** The agent searches wherever you pointed. Ask it to restate the problem first, then share your hunch.
+- **Taking the first design.** One attempt locks in the first shape the model thought of. Ask for prototypes or `/architect` and pick from evidence.
+- **Polishing an abstract plan.** Adversarial review of a plan with no code behind it invents risks that will never happen. Settle the open questions with prototypes, then review what got built.
+- **Parallel agents in one worktree.** They overwrite each other, and nobody can tell which agent changed what. Run them as cloud agents, or say "own worktree per attempt".
+- **Looping before you trust the loop.** A loop that can't verify its own work only makes unchecked work faster. Get the verification skill working first.
+- **Trusting an unvetted number.** A warm cache or a skipped code path can fake a speedup. Run `/benchmark-checklist` before the number goes anywhere.
+- **Correcting the same mistake by hand.** A correction in chat helps one run. `/correct` fixes the repo so no later run repeats it.
 - **Using `/arena` for coverage.** `/arena` repeats one design or code brief, then picks a base and grafts the best parts. `/swarm` partitions slices or declared race arms and aggregates one report.
 - **Accepting every review comment.** Bots and humans both file real catches and noise in one list. `/interrogate` sorts findings into act-on and dismissed buckets with reasons, and you can override either way.
 - **Treating `auto` as a model slug.** `auto` and `inherit-parent` mean "omit the model field so the subagent inherits the parent chat model." [Setup](./01-setup.md) covers the roles.

+# pstack in Claude Code
+
+pstack skills use Cursor names. In Claude Code, read this file once per session, then map each Cursor name in a skill with the tables below. `<pstack>` means the folder that holds `skills/` and `docs/`. If a Cursor field has no row, drop it and say so. Never pass a field or value the tool schema rejects.
+
+## Tools
+
+| Cursor | Claude Code |
+| --- | --- |
+| `Task` | `Agent` |
+| `AskQuestion` | `AskUserQuestion`. In `-p` mode it is absent, so ask in plain text. |
+| Open a todolist | Use `TodoWrite` if the session offers it. Otherwise keep the list in your reply and update it at each phase. |
+| Run another pstack skill (`/name` or "the **name** skill") | `Read` `<pstack>/skills/<name>/SKILL.md` and follow it. The `Skill` tool refuses most pstack skills. When you tell the user to type it, write `/pstack:<name>`. |
+| `Grep`, `Glob` | `Bash` with `rg` when the session has no `Grep` or `Glob`. |
+
+## Subagent fields
+
+| Cursor | Claude Code |
+| --- | --- |
+| `subagent_type: generalPurpose` | `subagent_type: "general-purpose"` |
+| `poteto-agent`, `comment-sicko` | `pstack:poteto-agent`, `pstack:comment-sicko` |
+| `readonly: true` | `subagent_type: "Explore"`. It keeps `Bash`, so the brief also says "do not edit files", and you check `git status` afterward. |
+| `readonly: false` | `general-purpose`. It keeps the session's MCP servers. |
+| `environment: "cloud"` | `isolation: "worktree"`. Name the branch or commit the worker checks out. |
+| `environment: "local"` | Omit. |
+| `cloud_base_branch: <b>` | Tell the worker to check out `<b>` first. |
+| `run_in_background: true` | Omit. Subagents run in the background by default and notify you when they finish. |
+| `resume` | Spawn a new agent and paste the earlier result into its brief. |
+| `file_attachments` | List the paths in the brief. |
+
+## Models
+
+| Cursor | Claude Code |
+| --- | --- |
+| `claude-<family>-<version>-<effort>[-fast]`, such as `claude-opus-5-5-xhigh` | `model: "opus"` and `effort: "xhigh"`. `model` takes only `opus`, `sonnet`, `haiku`, `fable`. Drop `-fast`. |
+| A `grok-*`, `gpt-*`, or other non-Claude slug | Omit `model` so the agent runs on the session model, and say so. |
+| `auto` or `inherit-parent` | Omit `model`. |
+| The `pstack-models.mdc` rule, `~/.cursor/rules/pstack-models.mdc` | `~/.claude/rules/pstack-models.md`. Claude Code loads it into every new session, so its role lines are already in context. If they are not, read the file. If the file or the role's line is missing, use the skill's default slug. |
+| A role value `<model> <effort>`, such as `opus high` | `model: "opus"` and `effort: "high"`. |
+
+## setup-pstack
+
+Claude Code loads every `.md` file in `~/.claude/rules/` into each new session, so `setup-pstack` writes its rule there. Follow its steps with these changes:
+
+- Detect. The detected models are the `model` values that the `Agent` tool schema lists, each with an effort from its `effort` values. Write a real model as `<model> <effort>`, such as `opus xhigh`. The effort is the last token, so the budget step works as written.
+- Defaults. Map each default slug with the rows above: `claude-opus-5-5-xhigh` is `opus xhigh`, and `grok-4.7-xhigh-fast` is `inherit-parent`.
+- Write. Write `~/.claude/rules/pstack-models.md` with no frontmatter, then the comment lines, the `# budget` line, and one line per role from step 5. Overwrite the whole file. Never put the role lines in `CLAUDE.md` or `AGENTS.md`.
+
+## Paths
+
+| Cursor | Claude Code |
+| --- | --- |
+| `.cursor/skills/`, `~/.cursor/skills/` | `.claude/skills/`, `~/.claude/skills/` |
+| `~/.cursor/plugins/`, `.cursor-plugin/plugin.json` | `~/.claude/plugins/`, `.claude-plugin/plugin.json` |
+| `.cursor/rules/*.mdc`, always-applied rules | `CLAUDE.md`, or `AGENTS.md` when no `CLAUDE.md` exists. Claude Code never reads `.mdc` files. The model rule is the exception. See Models. |
+| `https://github.com/cursor/plugins/blob/main/pstack/<path>` | `<pstack>/<path>` when that file exists. The plugin ships the skills, `docs/guide/`, and `README.md`. Read the local copy and never fetch it. Give the user the URL when they need a link. |
+| Transcripts in `~/.cursor/projects/<slug>/agent-transcripts/` | `~/.claude/projects/<slug>/<session>.jsonl`. The slug is the workspace path with each `/` and `.` changed to `-`, so `/Users/you/proj` is `-Users-you-proj`. The newest `.jsonl` directly in that folder is the current session. Its `<session>/subagents/` folder holds subagent transcripts. Read only this workspace's folder. |
+
+## Cursor-only features
+

+description: "Vet a perf measurement (limiter, tuning, limits, errors, repeatability, relevance, and whether the work happened) before you report or act on it. Use when you run a benchmark or report a speedup or regression you measured."
+disable-model-invocation: true
+---
+
+# Benchmark checklist
+
+Use this when you produce a performance number: a PR's before and after, a regression claim, a hillclimb harness, or a library or config choice. Answer each question with evidence from a run, not a guess about the code.
+
+For a quick ballpark the user asked for, one run is enough. Still check questions 4 and 7, and say that it is one run. Skip the rest unless that run looks wrong. A choice between options is never a ballpark.
+
+## Before you run anything
+
+- Write down the claim you expect to make, in the words you would ship ("export is 30% faster at p50 on the 60k-row dataset"). The questions test that sentence.
+- Read the measurement script. Note what it times, counts, and ignores.
+- Check the load average with `uptime` and the core count with `nproc`. If the machine is busy, find out what is running. If you cannot stop it, interleave the sides so both see the same noise, and say so in the report.
+
+## The questions
+
+1. **Why not double?** Name the limiter. Profile in a run you do not report, because profilers and tracers slow the work down. Use CPU per process (`top`, `pidstat`), a runtime profiler (`node --cpu-prof`, `py-spy`, `perf`), I/O wait, and syscall counts (`strace -c` on Linux), then map the hot spot to source. Watch the load generator too: if it saturates first, you measured the load generator. If a change did not move the number, the limiter explains why, so find it before you call the change useless.
+2. **Was it tuned?** Run every side the way production runs it: release builds, production flags and env, batching and transaction settings, connection pools, caches as warm or cold as production sees them, and the same versions and data. If one side runs on defaults, you compared configurations, not implementations. A limiter that is a setting (a commit per row, a debug build, a missing index) means that side is untuned. Tune it and measure again before you pick a winner. If you cannot tune it, do not pick a winner from that run. When the user is choosing what to adopt, narrowing the claim to the code as it ships today does not fix this, because they adopt the option, not today's settings.
+3. **Did it break limits?** Do the arithmetic. Compare bytes per second with disk and network bandwidth, operations per second times cost per operation with your cores, and the time saved with the time the changed piece took. Removing a piece that takes 10% of the run can make the run at most about 11% faster. A result past a limit measured something other than the work, such as a cache, a no-op, or a bug.
+4. **Did it error?** Count failures and non-success responses, and check that outputs are correct, not just present. Rejections are often fast, and timeouts and retries are slow. If the script does not count errors, add the count.
+5. **Does it reproduce?** Run each side at least 5 times, alternating (A, B, A, B, and so on) so warmup, lazy initialization, caches, and drift favor neither. Report the median and range. A gap smaller than the run-to-run variation is no measurable difference. When the call is close, use a rank-sum test or the harness's own statistics.
+6. **Does it matter?** Next to any micro result, measure the end-to-end path a user waits on, with realistic data sizes and concurrency, and report the micro result as a share of the whole. A helper that takes 1% of a request can make the request at most 1% faster, however fast the helper gets.
+7. **Did it even happen?** Confirm the work ran inside the timed region: the request reached the server, the rows were written, the bytes were read, and the code used the result. Lazy code (generators nobody iterates, promises nobody awaits, results the JIT can discard) and timeouts produce numbers for work that never happened.
+
+## Report
+
+- Lead with the verdict: faster, slower, no measurable difference, or inconclusive.
+- Give the number with its unit, the run count, the range, and the limiter. For example, "p50 41 ms → 33 ms, median of 7 runs per side, range 32 to 35 ms after, bound by JSON parsing on one core."
+- Call the verdict inconclusive when you claim a difference but cannot name the limiter, when a side ran untuned, or when you could not check questions 4 and 7. Name the gap.
+- Keep a PR body to one primary number, per the **Opening a PR** playbook. Put the runs, range, and limiter evidence in a linked artifact or notes file.
+
+## Other perf material
+
+- Vet the **Perf issue** playbook's baseline before the playbook plans from it, and every number after that.
+- Vet the **Hillclimb** playbook's harness before it is frozen. The frozen harness then prints error and work counts, so each keep-or-revert checks questions 4 and 7 for free.

+Assume every contributor is an agent that sees only the files it opened, copies the nearest example, and takes the shortest path that compiles. Design the repo so a change that looks right from one file is right for the whole repo.
+
+## Find the mistake classes
+
+First, read recent commits, reverts, review comments, agent instruction files, and comments that explain workarounds. Group the mistakes into classes. A class counts once it has happened twice.
+
+## Fix each class at the highest level that works
+
+1. **Eliminate it with architecture.** Give each piece of state one owner and each task one supported way. Hide internals so the wrong import fails. Replace hand-synced lists with one source of truth. Delete old ways and dead code an agent would copy.
+2. **Enforce it with types so the bad state can't be written.** If bad code still compiles, add a lint or CI check whose error names the file, type, or function to use instead. If the pattern is already common, fail only when a change adds more.
+3. **Test the behavior.** Fix or delete any test that still passes when the behavior it checks breaks, or that fails when only the internals change.
+4. **Write docs or agent rules last, only for judgment calls.** Nothing fails when an agent skips them.
+
+## Fix and prove
+
+Then fix the most frequent classes now, one commit each. Prove each new check fails on a real past mistake. Run the same command locally and in CI. Exceptions go on the offending line with a reason, an expiry date, and a human's approval.
+
+## Keep the rule table
+
+Last, keep a table in the agent instruction file that pairs each rule with what enforces it. When the operator corrects you, fix the mistake and add the rule. If the rule was already there and nothing enforces it, that's a repeat, so fix it at the highest level in the same change. Drop a rule once its mistake can't happen.

+
+# Create a formal verification skill
+
+A test checks the cases that someone thought to write. Formal verification checks every case in a stated scope: every order of steps in a model, every input up to a bound, or every input. This skill finds the part of the repo where that matters most, verifies one property of it, and leaves a project-local skill that lets the next agent check a change against that property. Write that skill for an agent who reads it cold, mid-change, and has never seen your work. The user must be able to trust the result and act on it without learning the verification language.
+
+## Choose the target from the code
+
+Answer from the codebase, and ask the user only what you cannot observe. If the user named an area or a bug, start there.
+
+A good target is a promise the code makes, where a break harms users and tests rarely reach the case that breaks it. Choose the strongest such target in the repo, not the one that is easiest to verify.
+
+## Let the question choose the tool
+
+Pick the tool that answers the question at the lowest cost: a model checker, a proof assistant, an SMT-backed verifier, or another tool. Whether events can happen in a bad order usually suits a model checker over a small model of the design, and TLA+ is the default for that in any language. Whether the code itself behaves for every input, as with memory safety, overflow, or a data-structure invariant, usually suits a verifier that runs on the code. If no verifier runs on this language, say so, and test the real code with generated inputs, not a hand model of the function. A property that must hold at every size, where a bound is not enough, can need a proof. Prefer a tool that the repo's developers can install and run, and tell the user why you chose it.
+
+## What makes it good
+
+- **True to the code.** Every part of the model or proof points to code that a reviewer can open. What the verification treats as one indivisible step is one indivisible step in the code. Names come from this repo.
+- **Able to fail.** A check that you have never seen fail proves nothing. Show each property failing on a broken variant of the code it guards, such as a removed check or a reordered step.
+- **Findings stay findings.** When the current code breaks the property, report it with the counterexample in the code's terms. Do not weaken the property or the model until it passes, and do not change product code unless the user asks.
+- **Honest about scope.** Say what is verified, under which bounds and assumptions, and what is left out. A pass covers the model or the bound, not the whole system.
+- **Readable without the tool.** State the property and the harm in one plain sentence each. Tell a counterexample as a short sequence of steps in the code's words.
+- **Cheap to rerun.** One command, a reproducible tool version, and a run short enough that the next agent will use it on every relevant change.
+- **Kept in step with the code.** Record which files and functions each check covers, and the commit at which you last confirmed that the verification describes them. When the covered code changes after that commit, the next agent can see that the verification needs another look.
+
+## Generate the verify skill
+
+Write a project-local skill with frontmatter that names the area and says when to use it. Without frontmatter, the skill never registers. From the skill alone, the next agent must be able to tell whether a change touches the verified code, run the check, tell a real bug from a modeling error, and update the verification when a change is intended. Put the coverage record and the sync commit in the skill, and tell the next agent to move the sync commit forward only after it confirms that the verification describes the code at the new commit. Use this repo's real commands, paths, and nouns, and leave no placeholders.
+
+## Prove it before you hand off
+
+Follow the generated skill once, as the next agent would, on a scratch change that breaks the property in the real code. It must catch the break. Then drop the scratch change and confirm that the check is back where it started: passing, or failing only on the findings you will report. A verify skill that was never run is a draft. If the skill misses the break or a step does not run, fix the skill or the verification, not the scratch change.
+
+## Hand off
+
+Tell the user what you verified, which tool you used and why, the bounds, what the check found in plain words, how to run it, and what it does not cover. Suggest a second target only if you found a close one. Point the user at `/maintain-formal-verification-skill` for bringing the verification back in line after changes that did not recheck it.

-Adversarial reviewers are useful because they're aggressive. But aggression without context produces noise. The reviewers only saw a slice of the codebase and a one-paragraph intent statement. They don't know:

-- What constraints exist outside the code (timeline, dependencies, migration plans)
-- Which parts of the code are temporary scaffolding vs. permanent architecture
-- What the next PR in the stack will address

+
+# Ketchup
+
+Catch the user up on what changed in this chat since the last message they wrote before `/ketchup`, and help them understand each change, not only where it stands. Then lay out every call waiting on them so they can make it from your reply alone. Notifications and subagent results are not their messages. Assume the user remembers their last message and nothing after it.
+
+Use [`/bro`](../bro/SKILL.md)'s voice, not its task: plain words, short sentences, no jargon, like one person catching up another. Say what changed for the user, not how you did it. Say "the tests pass", not "CI is green". Leave out hashes, file paths, commands, build numbers, and test counts unless the user needs one to act. Call each PR, branch, or agent by a name the user would know, not by a label you invented. If a fact needs context to make sense, give the context or leave the fact out.
+
+## Gather what changed
+
+Keep this turn read-only. Make visuals only from what you already have: do not change code, start an app or a job, or post anything. Collect your own work since that message, reports from subagents, and messages from anyone else in this chat. Check the current state of each PR, CI run, or agent this chat touched. Check each number you will show against the facts it comes from, and say so when you correct one.
+
+An action item is a call or step only the user can take, such as a product choice, an approval, an irreversible action, or access you lack. Include any still waiting on the user, even one raised before their last message. Work you can still do yourself is not an action item. Never make up a call to fill the reply. A step the user did not ask for and the work does not need is not an action item, unless it is irreversible and waiting on the user: give it one line and no visual.
+
+One call can cover many items, such as each PR in a set awaiting merge. For each item, collect its link, what it changes for users, the evidence behind your pick, its risk, and your pick. Write "unknown" for a fact the call needs that you do not know. Leave out a link you do not have.
+
+## Write the reply
+
+Spend words on the calls, not on the story. Keep what happened under 100 words, not counting pictures, and shorter when less happened. Leave out work that changed nothing for the user. Give each item about 30 words. The reply grows with the number of items: two items need well under 150 words in all, not counting pictures, and thirty need far more. Never cut items or shrink them to stay under a word count: no count in place of a list, and no link in place of an item. A link can add depth, but the reply alone must be enough to decide.
+
+Open with one short sentence that names what waits on the user, or says nothing does. The action items give the detail. If nothing happened and nothing waits on the user, say so and stop.
+
+Then show what happened, pictures first. Embed inline the screenshots and videos the work produced, then any diagram that explains a change. Then sum up in one short bullet per thing the user asked for: what came of it, and whether it is done, still running, failed, or not checked. Write each line the way you would say it out loud: "Search was slow from a missing index", not "Search review: done" or "Slow search: missing index". Name any bug found and fixed on the way. Each line must stay true when read alone. Never mark something done that still waits on the user, and leave out anything the action items say. Under the summary, give at most three short lines that change what the user knows or must do. Then name in one line any work left that you can do yourself.
+
+Then list the action items. Ask the call the user owns, such as merge, approve, or pick, and give your pick. A step you would take first goes in your pick. So does anything that must happen first, and anything that cannot be undone. Give the number or link of each PR, issue, or agent a call is about, also in a call between options.
+
+Fit the shape to the call. A call about one item is one bullet: the call, your pick, what it changes for users, the evidence behind your pick, and its risk, with the item named once. When items share a call, write the call and your pick once, then give each item its own bullet, riskiest first: its link and name, what it changes for users, the evidence behind your pick, and its risk. Name an item's pick only where it differs from the call's. Give each item's risk even when it is low, such as "Low risk: only the colors change." Say what waiting costs only when it is more than a delay, such as a deadline or lost data.
+
+For a call between options, give every option the work weighed, each with what it gets the user and what it costs, and the current state when there is one. Those costs are the call's risk, so add no separate risk line. When the screenshots above show the options, write each option's gain and cost under its screenshot.
+
+## Visuals
+
+A visual is a picture: a screenshot, a video, a Mermaid diagram, a chart or diagram from `/visualize`, or a generated image. A Markdown table is not a visual, even with before and after columns.
+
+When something is easier to grasp as a picture than as sentences, draw it: how a design or system works, a PR stack or dependency chain with each PR's state, a before and after of a fix, or options side by side. Never draw a status list, a list of action items, or boxes with nothing connecting them. Never give a fact twice, in text or across visuals.
+
+Keep each visual small enough to read at a glance: at most six boxes, with at most eight words in each. Write labels as plain words a person would say, not tags like "Tests: pass". A fact that needs a sentence belongs in the text, or nowhere.
+
+Embed screenshots and videos inline when the change is visible, not only as links. If a visible change has none, mark its summary line "No screenshot yet," and say there what changed on screen. Draw diagrams and charts from facts you have: a Mermaid diagram for how things connect and a `/visualize` chart for numbers. Never invent a number, and never draw or generate a picture of a screen you did not capture. Link only artifacts that exist.

+description: "Bring a project's formal verification back in line with the code after the code changes: find the commits that touched verified code, update the model, harness, or properties to describe the code as it is now, rerun, and say whether each failure is drift in the verification or a bug in the code.

+
+# Maintain a formal verification skill
+
+A formal check proves a property of what it describes. When the code changes and the verification does not, the check can keep passing while it describes code that no longer exists. That pass is the dangerous case, because it looks like a proof. This skill is the upkeep loop for a verify skill that `/create-formal-verification-skill` generated, or for any project-local skill that runs a model checker, prover, or code-level verifier against named code. The project-local skill handles a change that an agent makes while it uses that skill. This skill handles the changes that skipped it: merges, edits made without the skill, and drift that builds up across many commits.
+
+## Outcomes
+
+Give each check one outcome, and say which:
+
+- **in sync**: no change since the last sync alters what the check describes, and the check passes.
+- **updated**: the code changed, the verification now describes the new code, and the check passes.
+- **bug**: the verification describes the current code, and the code breaks the property. This is a finding about the code. It is not drift.
+- **blocked**: the check could not be brought back in line or could not run. Say exactly why.
+
+A check can be both updated and bug: the update makes the verification describe the code again, and then the property fails on it.
+
+## Edit scope
+
+Edit only the verification: models, harnesses, property files, and the verify skill itself. Never edit product code during a run, unless the user asks you to. When a property fails on the current code, do not weaken the property or the model to make it pass. Report the failure.
+
+## Pass
+
+1. **Find the checks.** A verify skill has no fixed name, so find it by what it does: a project skill that runs a model checker, a prover, or another verifier against named code. Read each one you find, or the one the user named. For each check, collect the property, the code it covers, the bounds and assumptions, the command that runs it, and the commit where it was last confirmed to describe the code. If no verify skill exists, stop and point at `/create-formal-verification-skill`. If the skill does not record a sync commit, use the last commit that changed the verification files, and say that you did.
+
+2. **Run it as it is.** Run each check once before you change anything, and record the result. A pass here does not tell you that the code is correct. It tells you that the old description still holds. A failure here can be drift or a bug. Do not decide which until step 5.
+
+3. **Read every change to covered code.** Diff the covered files from the sync commit to the current commit, and read each commit message. Also look for code that moved: a covered function that is renamed, split, or moved to another file is still covered code. Also look for new code that touches the state that a check guards, such as a new function that writes the same fields. For each change, decide which of these it is:
+   - **No effect.** The change does not alter anything the verification describes, such as formatting, comments, or code paths that the verification does not cover. Check this against the model or harness, not against the commit message.
+   - **The verification no longer describes the code.** A step that was one indivisible action is now two, a branch was added or removed, a check moved, a new path reaches the guarded state, or a value now has a different range. The model or harness must change.
+   - **The promise changed on purpose.** The change alters what the code promises, and evidence in the change says that this is intended: the doc comment, the tests, the changelog, or the commit message. The property must change, and you must cite that evidence.
+   - **The promise may be broken.** The code changed, and no evidence says that the promise changed. Treat a failure that follows as a bug candidate.
+
+4. **Update from the code, not from the result.** Change the model or harness so that each changed part again points to code that a reviewer can open, and keep one indivisible step in the code as one step in the verification. Write the update from the code before you rerun, and do not shape it by what makes the check pass. Change a property only for a promise that changed on purpose. Write down the old wording, the new wording, and the evidence. Keep the bounds unless the change makes them wrong. If you must reduce a bound, say so in the report.
+
+5. **Rerun and judge each result.**
+   - **Pass:** the check can now pass on a description that has lost the ability to fail. Break the new code the way the property guards against, such as removing a new check or reordering a new step, and confirm that the check catches it. Then drop the break.
+   - **Fail:** replay the counterexample against the real code, step by step. If a step cannot happen in the code, the verification is wrong. Fix the verification, and say what was wrong. If every step can happen, it is a bug. Name the commit that introduced it, tell the counterexample as a sequence of steps in the code's own words, and state the harm in one sentence. If a cheap test or reproduction against the real code shows the bug, add it to the report as evidence. Do not commit it to the product code.
+
+6. **Update the verify skill.** Update the code that each check covers, the commands, the bounds, the assumptions, and the sync commit. Set the sync commit to the commit that you checked. Do not move the sync commit for a blocked check, and say so in the report. Then follow the verify skill once as the next agent would, so that you know its steps still run.
+
+## Report
+
+Tell the user, for each check:
+
+- the outcome, and the commits that you read;
+- what changed in the verification and why, with a short reason for each change: the code changed shape, or the promise changed on purpose (with the evidence);
+- the rerun result, and the break that you used to show the updated check can still fail;
+- each bug, in plain words: the counterexample as steps in the code's words, the harm, and the commit that introduced it;
+- what the verification still does not cover, including new code that it should cover and does not.
+
+Say outright which failures were drift in the verification and which were bugs in the code. For a check that passed before you updated it and fails after, say that the old pass was on a stale description.
+
+Put the verification updates in a change of their own, separate from any product fix.

+1. Spawn `Task` with `subagent_type: "comment-sicko"`. Pass the scope. Pick each subagent's reasoning level and fast or standard speed for the job, per the Subagents section of the **poteto-mode** skill. Do not restate its rules.
 2. Inspect its report and diff. Reject application-code edits, scope escapes, exception-protected deletions, misstated `MUST KILL` reasons, and flags that treat kept intentional code as guilty. Reshape flags on our-code surprises stay actionable. Do not restore those comments. A keep survives only with proof it is about something we cannot change. Audit missed scoped lint and TypeScript suppressions. Correctness or safety suppressions stay actionable `MUST KILL`s. Restore deletions only with exact exceptions and scoped proof. Before accepting thin `IMPORTANT` or `do not remove` kills or keeps, run `/how` or `/why` on their symbol. If a kill is ambiguous, do not restore. If a keep is refuted or still ambiguous, delete it. Revert and rerun one rejected report with the failure named. Reject a second, report it open, and fail `/no-comments`.
 3. Fix trivial accepted flags directly by deleting a dead path, dropping a parameter, or using the real API. If any fix needs a shape, run `/architect` once for the accepted set and surrounding code. Stop at the sketch. Architect shapes. Step 4 implements.
 4. Implement the smallest root-cause fix in scope. Remove every named workaround. If the root cause is out of scope, land the smallest in-scope fix and report the rest open. The **principle-fix-root-causes** and **principle-redesign-from-first-principles** skills guide intent only. Neither authorizes widening the fence nor fixing instances outside it. Never bolt on symptom guards.

+
+Answer the user's question about pstack, hand them a prompt they can send, and link the file the answer came from. For a help question, don't start the work. The user asked how, and a pstack run spends real tokens, so let them send the prompt.
+
+A message that asks for work, such as "use pstack to fix this bug", is not a help question. Read [`poteto-mode`](../poteto-mode/SKILL.md), do the work under it, and mention once that a Custom Mode keeps it on.
+
+This file maps questions to the skills and guide pages that hold the answers. Those files own the details. Read the file you route to before you quote it, and trust it when it disagrees with this map. The links here point into the installed plugin, which the user may not be able to open, so give the user the file's public copy: `https://github.com/cursor/plugins/blob/main/pstack/` followed by its path.
+
+## Find out what they need
+
+Infer the need from the message and the conversation. A named situation, such as "which skill reviews a PR?", goes straight to its section. If the need is still unclear, ask one multiple-choice question with these options, then answer only the section they pick:
+
+- Get set up
+- Start a task with `/poteto-mode`
+- Pick a skill for a situation
+- Fix a run that went wrong
+- Make pstack my own
+
+Check the state that changes the answer, and mention it only when it does:
+
+- No `~/.cursor/rules/pstack-models.mdc` means `/setup-pstack` hasn't run for this user, so every role uses its default model.
+- No `verify-*` skill or other app harness in the project means agents have no scripted way to drive the app. Mention `/create-verification-skill` when the question is about proving a change works.
+- No formal verification skill in the project means no property is checked past what tests reach. Mention `/create-formal-verification-skill` when the question is about a race, an invariant, or another case tests rarely hit. When one exists and the code it covers changed after the commit it records as last in sync, mention `/maintain-formal-verification-skill` if the question touches that code.
+
+When the model rule is missing and it matters, ask whether the user wants to pick a model for each role and a reasoning budget now. It matters when the user is new, the question is about setup or cost, or the answer depends on which models run. Ask at most once per chat. If the need is also unclear, ask both questions together. Offer two choices:
+
+- Now: give them `/setup-pstack` to type, and answer their question too.
+- Later: answer their question, and add one line saying every role keeps its default model until they run `/setup-pstack`.
+
+## Get set up
+
+1. Install with `/add-plugin pstack` in chat, or from Customize in the sidebar.
+2. Run [`/setup-pstack`](../setup-pstack/SKILL.md). It asks for a reasoning budget, maps a model to each role, and writes a rule. The rule applies to new chats. Then it offers once each to generate a verification skill and a formal verification skill for the project, unless the project already has one.
+3. Start a real task with `/poteto-mode`, a goal, and a check that can pass or fail.
+
+Installing changes nothing until the user invokes a skill. Only `/setup-pstack` loads from the user's words. The [README](../../README.md) and [guide page 1](../../docs/guide/01-setup.md) have the details. Offer to word their first prompt with them, per [`references/prompting.md`](references/prompting.md).
+
+If cost is the worry, say where the tokens go and how to spend fewer. pstack spends extra tokens on subagents and review panels. Rerun `/setup-pstack` and pick a smaller budget or cheaper models. A role set to `auto` or `inherit-parent` runs on the chat's model, which saves tokens when the chat runs on Auto or a cheaper model. A shorter panel list runs fewer subagents, one for each entry. Save `/poteto-mode` for work that needs rigor.
+
+pstack is built for Cursor, and it also installs in Claude Code with `/plugin marketplace add cursor/plugins`, then `/plugin install pstack@cursor-plugins`. There, each command takes a `pstack:` prefix, such as `/pstack:poteto-mode`. The [Claude Code adapter](../../docs/harness/claude-code.md) maps the Cursor names, and a step that needs a Cursor-only feature, such as Bugbot or Automations, is skipped with a one-line note.
+
+Other tools can read the skills, because they use the Agent Skills format. But most workflow skills, including `/poteto-mode`, `/how`, `/why`, and `/teach`, spawn Cursor subagents with per-role models, and Custom Modes and `/loop` are Cursor features, so those parts may not work there.
+
+## Start a task with `/poteto-mode`
+
+`/poteto-mode` matches the task to a playbook, copies the playbook's steps into the todo list, and runs the other skills as the steps need them. A step it skips stays in the list as `skip: <reason>`. A good prompt states the goal and how to tell it's done. It doesn't list skills, because a hand-written sequence tends to drop or reorder steps the playbook would keep. Read [`references/prompting.md`](references/prompting.md) before you help word one. [Guide page 2](../../docs/guide/02-poteto-mode.md) has examples.
+
+Whether `/poteto-mode` stays on depends on how the user starts it:
+
+- Enter on `/poteto-mode` attaches the skill to one message. It fades as the chat moves on.
+- Option+Enter on Mac or Alt+Enter on Windows, or Use as Mode from the skill entry, makes it a Custom Mode. It stays in context every turn until the user exits the mode, and it stays out of casual turns.
+- Cursor's docs list Custom Modes in the Agents Window and the CLI. Elsewhere, start each new task with `/poteto-mode`.
+
+Link [Cursor's skills docs](https://cursor.com/docs/skills) when this comes up. Mid-chat, "new task" makes the mode match a fresh playbook. `/poteto-mode` already uses `poteto-agent` for the subagents its playbook steps spawn. To get the same style from a subagent of your own, spawn it with `subagent_type: "poteto-agent"`.
+
+## Pick a skill
+
+The default answer is `/poteto-mode`, which runs most of the others when its steps need them. Name a skill directly when the user wants more or less of something than the playbook gives. Read the skill before you recommend it, and give one example prompt.
+
+| The user wants to | Skill |
+|---|---|
+| Do any non-trivial task with rigor | [`/poteto-mode`](../poteto-mode/SKILL.md) |
+| Check that the agent understood their goal and the problem before it starts | [`/in-your-own-words`](../in-your-own-words/SKILL.md) |
+| Get a prompt rewritten deeper, not bigger, before sending it: what a top professional would add, their raw material and methods, and an outside check. It returns the prompt and doesn't do the task | [`/sharpen`](../sharpen/SKILL.md) |
+| Know how code works now, or where new code should live | [`/how`](../how/SKILL.md) |
+| Know why code is shaped this way, or where a number came from | [`/why`](../why/SKILL.md) |
+| Understand a change or subsystem, explained plainly | [`/teach`](../teach/SKILL.md) |
+| Catch up on their own recent work on a topic | [`/recall`](../recall/SKILL.md) |
+| Catch up on what changed in this chat since their last message, in plain words and small visuals, with every item waiting on them listed and decidable from the reply alone | [`/ketchup`](../ketchup/SKILL.md) |
+| Know what a small diff could break outside itself | [`/blast-radius`](../blast-radius/SKILL.md) |
+| Settle types and module shape before code that crosses a function boundary | [`/architect`](../architect/SKILL.md) |
+| Get several attempts at one brief, merged into the best one | [`/arena`](../arena/SKILL.md) |
+| Run parallel checks over slices, or race workers, as cloud agents | [`/swarm`](../swarm/SKILL.md) |
+| Have different models review a diff and try to break it | [`/interrogate`](../interrogate/SKILL.md) |
+| Fix a bug test-first when a cheap local test exists | [`/tdd`](../tdd/SKILL.md) |
+| Apply TypeScript rules to `.ts` or `.tsx` work | [`/typescript-best-practices`](../typescript-best-practices/SKILL.md) |
+| Strip comments before review, using a reviewer that didn't write them | [`/no-comments`](../no-comments/SKILL.md) |
+| Clean AI tells out of prose | [`/unslop`](../unslop/SKILL.md) |
+| Write docs, an RFC, a README, a PR description, or a commit message to a standard | [`/technical-writing`](../technical-writing/SKILL.md) |
+| Hear the last reply again in plain words | [`/bro`](../bro/SKILL.md) |
+| Give agents a scripted way to drive the app and prove behavior | [`/create-verification-skill`](../create-verification-skill/SKILL.md) |
+| Bring a verification skill and its feature map back in line with the app | [`/maintain-verification-skill`](../maintain-verification-skill/SKILL.md) |
+| Formally verify a race, invariant, or other property that tests rarely reach | [`/create-formal-verification-skill`](../create-formal-verification-skill/SKILL.md) |
+| Bring a formal verification back in line after the code it covers changed, and learn whether a failure is drift or a bug | [`/maintain-formal-verification-skill`](../maintain-formal-verification-skill/SKILL.md) |
+| Vet a performance number before reporting or acting on it | [`/benchmark-checklist`](../benchmark-checklist/SKILL.md) |
+| Run a large or cross-cutting change, or one to review after stepping away | [`/figure-it-out`](../figure-it-out/SKILL.md) |
+| Keep a decision log during a run, and review it afterward | [`/show-me-your-work`](../show-me-your-work/SKILL.md) |

+| Build a page whose buttons wake a Grok Bot over a webhook | [`/make-bot-ui`](../make-bot-ui/SKILL.md) |
+| Find their way around pstack | `/poteto-help` |
+
+If a skill directory next to this one is missing from the table, read its frontmatter and route by its description. The `principle-*` directories are covered under principles below.
+
+Close calls:
+
+- `/how` explains what the code does. `/why` explains the reasons. `/teach` runs one or both and explains the result plainly.
+- `/arena` gives every worker the same brief and merges the best parts. `/swarm` splits work into slices or a race and returns one report.
+- `/architect` implements right after it settles the design. Add "with checkpoint" to review the design before it writes code.
+- `/interrogate` reviews the diff. `/blast-radius` looks for breakage outside the diff and proves the one fact that makes the change safe.
+- `/recall` rebuilds context across recent chats. `/ketchup` covers only this chat since the user's last message. Resuming one specific chat or branch is the Session pickup playbook.
+- `/figure-it-out` designs one rigorous run. The Orchestrate playbook runs a program that spans days and many PRs. The Autonomous run playbook drives one task to a finish condition.
+
+Not in pstack:
+
+- `/deslop`, `control-cli`, and `control-ui` ship in the `cursor-team-kit` plugin.
+- `/loop` and `/create-skill` are Cursor built-ins.
+- pstack has no `/orchestrate` skill. Orchestrate is a `/poteto-mode` playbook. If the slash menu shows `/orchestrate`, another plugin provides it.
+
+## Playbooks and principles
+
+Playbooks are step lists inside `/poteto-mode`, not skills, so they have no slash command. Inside `/poteto-mode`, describing the task picks one, and these phrases name one directly:
+
+- "babysit this pr" or "check on pr 123" runs Babysit. It drives the PR to merge-ready and stops there. It doesn't merge unless the user asks to merge, land, or ship.
+- "land the stack" runs Shipping.
+- "take over this branch" runs Session pickup.
+- "pause safely" runs Pause safely.
+- "full autopilot on this queue" runs Autopilot-full. "stack them, don't ship" runs Autopilot-stack.
+- "run the eval playbook" runs Eval.
+
+Without `/poteto-mode`, a phrase such as "babysit this pr" can start Cursor's own skill for the same job instead. The Playbooks section of [`poteto-mode`](../poteto-mode/SKILL.md) lists every playbook and when it applies. [Guide page 6](../../docs/guide/06-verify-and-ship.md) covers opening, babysitting, and landing a PR.
+
+pstack has no planning skill. Cursor's Plan Mode works alongside it. For work that spans phases or stacked PRs, asking `/poteto-mode` for a plan runs the [Multi-phase plan playbook](../poteto-mode/playbooks/multi-phase-plan.md), which writes the plan and doesn't implement it. For a design question, the Prototype playbook or `/architect` settles it in code first.
+
+Principles are one-rule skills that `/poteto-mode` reads and cites in its replies. The user rarely invokes one. They steer with the names instead, as in "apply prove it works. show me the real output." Typing `/principle-<name>` still loads one on demand. [Guide page 8](../../docs/guide/08-principles.md) lists them.
+
+## Fix a run that went wrong
+
+| Symptom | Fix |
+|---|---|
+| The mode stopped applying after a few turns | It was started with Enter. Start it as a Custom Mode, or start each task with `/poteto-mode`. |
+| A question got treated as the next step of the last task | Say "new task", or say the turn doesn't need the mode. |
+| A new model choice had no effect | The rule from `/setup-pstack` applies to new chats. Start one. |
+| Runs cost more than expected | See the cost paragraph under Get set up. |
+| A skill didn't load on its own | Only `/setup-pstack` loads from the user's words. The others load when the user types them or when `/poteto-mode` runs them, and it doesn't run every skill. |
+| Parallel agents overwrote each other | Give each agent its own worktree, or run them as cloud agents, which each get their own machine. |
+| An overnight run moved but finished nothing | `/loop` needs a check that can pass or fail, not a duration. See [guide page 7](../../docs/guide/07-overnight.md). |
+| The reply claims success from a green build | Ask for the real command, flow, stored value, or profile. That's the prove-it-works principle. |
+
+For a run that drifts, [`references/prompting.md`](references/prompting.md) has one-line steers. [Guide page 10](../../docs/guide/10-recipes-and-pitfalls.md) has more pitfalls and the recipes worth copying.
+
+## Make pstack my own
+
+- [`/automate-me`](../automate-me/SKILL.md) drafts a personal mode skill from the user's own history, to use alongside `/poteto-mode`.
+- [`/reflect`](../reflect/SKILL.md) after a session turns its lessons into skill edits the user approves.
+- `/poteto-mode write a skill for <workflow>` runs the authoring playbook. The eval playbook tests a skill change blind.
+- Fix a misbehaving skill in its own PR, not inside the feature work where it went wrong.
+
+[Guide page 9](../../docs/guide/09-make-it-yours.md) covers each of these.
+
+## Reply

+Lead with the answer. Give at most one example prompt in a code block, adapted from [`references/recipes.md`](references/recipes.md) when one fits, then the link to that file. Keep it short unless the user asked for the whole map.

+# Word the prompt
+
+A prompt states the intent and the check for done. The playbook supplies the steps, so a few plain sentences beat a spec.
+
+## Put in
+
+- The goal. Say what is wrong or what the user wants.
+- The done check. It can pass or fail. "Make it better" and a duration are not checks.
+- The proof to show. Ask for the real command output, a video of the flow, the stored value, or a before and after number.
+- What the user already knows. A symptom, a repro step, a log, or a link saves the agent a search.
+- The real constraints. "repro first", "don't change any code yet", "zero behavior change", and "let me review before proceeding" each change what the agent does.
+
+## Leave out
+
+- The how. Say what to achieve, and leave the agent room to find a better way.
+- A list of skills or steps. A hand-written order drops or reorders steps the playbook keeps. Name a skill only to override one choice.
+- The user's theory of the cause, until the agent restates the problem. A stated guess narrows the search.
+
+## Load the context first
+
+- For a noisy report, ask the agent to restate the underlying issue in its own words and in plain English before it does anything else. A misreading shows up before any code exists.
+- In a fresh chat, `/recall` earlier work on the topic. Old chats hold context that the new agent lacks.
+- Before a change to unfamiliar code, ask `/how` for the mechanics and `/why` for the reasons. An agent with no traced model fixes the symptom at the first plausible spot.
+- Ask `/teach` to make the case for a choice, as in "convince me it fixes the cause and not the symptom". A case is easier to check than a summary.
+
+## Design before the plan
+
+- Never take the first design. Ask for prototypes of a few options, with screenshots or videos for UI, and pick from the evidence.
+- Let prototypes answer the open questions. Don't review an abstract plan adversarially, because reviewers invent risks that never happen.
+- For a shared package or API, ask for the README or a tutorial first, then work back to the code. The doc becomes the target the agent checks itself against.
+- Ask for the plan only after the design is settled. Each step of the plan ends in a check.
+
+## Follow up short
+
+- "do it", "continue", and "keep going until done" are whole prompts once the chat holds the task.
+- Start with "new task" when the subject changes. Otherwise the mode treats the message as the next step.
+
+## Before stepping away
+
+- Say "im going to bed" or "im stepping away" so the agent stops asking.
+- Write done as checks every iteration can run, and give `/loop` that predicate.
+- Ask for a fresh worktree off a named base.
+- Pre-answer what the agent would stop for, such as "don't ask me before committing".
+- Ask for a decision log to audit later.
+- Give an exit: "if you're truly stuck after a few hours, stop and write up why".
+
+## Steer in one line
+
+- Restate the goal: "i said the goal is to repro. i did not ask for a fix yet."
+- Name the principle: "apply prove it works. show me the real output, not the build log."
+- A principle name works because the agent already read the rule. Its reply names the decision the rule changed.

Per-role lines in the `/setup-pstack` rule override these defaults and the model choices in the routed skills (`how`, `why`, `arena`, `swarm`, `architect`, `interrogate`, `reflect`).

The `/setup-pstack` budget sets each role's starting level, xhigh by default. Raise it one step, up to max, for the hardest or subtlest work. Lower it one step for judgment and two or more steps for routine work. Use fast mode only when the job is urgent, meaning CI or trunk is red or a person is blocked on the result right now. Otherwise use standard speed, the same slug without `-fast`. Verification is the exception and stays on the `swarm workers` model and speed (`grok-4.7-xhigh-fast` by default). Change only the effort level and whether the slug is fast, and keep the family the role names, so a diverse panel stays diverse. If the family has no slug at that level and speed, use its nearest slug. A role on `auto` or `inherit-parent` stays on the parent model. If the Task tool rejects the adjusted slug, do not try another adjusted slug. Use the role's line or default and say so.

 ### Autopilot-full
 
-**You own the verdicts, never the PRs. One owner runs each PR from build to merge, and nothing merges without your clean swarm verdict.** For "autopilot this queue", "full autopilot", and one-owner-per-PR programs. Orchestrate runs a standing program whose coordinator lands verified work itself and whose workers never merge. Here each PR's owner carries the whole lifecycle through the merge, and the root keeps only verification, countersigns, and audits.
+**You own the verdicts, never the PRs. One owner carries each PR from build to merge, and nothing merges until your swarm, which never wrote the code, has proven the code that lands.**
 
-1. **Mark the operator's items and honor state-then-wait.** Items the operator names stay with the operator. The operator reviews and clicks, and no owner merges one. When the operator asks for the protocol or the plan to be stated, deliver the statement and stop. Execution starts only on the operator's explicit go. On that go, arm a `/goal` with the full program objective. The goal continues across turns until the queue is done.
-2. **Spawn one owner per PR with the full lifecycle and an early trail.** Resolve the forge once for the program. GitHub CLI (`gh`) is the default. If `command -v origin` succeeds and Origin can resolve the repository, use `origin pr ...` for PR create, edit, view, watch, and merge operations. Otherwise stay on `gh` and record the fallback. Never require Graphite (`gt`). One Cursor cloud agent per PR owns build, the first push, a ready PR, self-proof on the real artifact (the **prove-it-works** principle skill), skeptical Bugbot triage per `../references/bugbot-triage.md`, a slop-strip (the `deslop` skill from the `cursor-team-kit` plugin (`/deslop`)), `/no-comments` (the **no-comments** skill), a rebase onto current trunk, the babysit loop to green (`playbooks/babysit.md`), and the merge itself. Within about 15 minutes, every owner starts a `decisions.tsv` trail per the **show-me-your-work** skill, pushes its first branch snapshot, and opens the PR ready, never draft. Open the PR before self-proof so the URL, decisions, and checks form a durable trail. Keep `decisions.tsv` uncommitted and return it with the reports. As soon as a subagent starts, the owner adds its ID, expected runtime (at least the longest past run of that kind), and state to a `children.tsv` kept the same way. The owner does the first rebase before the code-ready report and babysit, whether or not trunk has drifted. In fix rounds, the owner keeps that merge base. The owner rebases again only at merge prep (step 5), on a `git merge-tree` conflict with trunk, or on a CI failure that comes from a change on trunk. When the shipped code is final, after the slop-strip and `/no-comments`, it reports the code-ready head SHA. It also reports the SHA of each later push that changes the patch. Self-proof, CI, and babysit then run in parallel with the swarm. The owner reports merge-ready with the head SHA when self-proof, CI, and babysit finish. Before a push that starts a round, run the pre-review checks that the repo's AGENTS.md files and rules name for the touched paths. Run them on the committed head. A hook pass is not proof. To publish each rebase, push the owner's own branch with `git push --force-with-lease` after an `ls-remote` check. Never force-push a shared branch. The merge is the one step an owner may not take alone. Step 4 gates it.
-3. **Run owners in true parallel and never stack.** Many owners at once when PRs are self-contained: one writer per branch, disjoint files, cross-PR drift absorbed by rebase. Only genuinely overlapping work serializes. Self-contained PRs branch straight off main, and sequenced work is merge-then-branch. One exception: an owner that must split a genuinely dependent change may hold a short private base-branch stack.
-4. **Swarm-verify every round before its merge.** A round starts at the owner's code-ready head SHA and at each later push that changes the PR's patch. At that SHA, fan out parallel independent verifiers per the **swarm** skill and aggregate to one verdict. The merge needs a clean verdict from the round whose patch matches the merge-ready head. Audit the receipts in the merge-ready report before the verdict. The lanes: re-run the gates at that SHA. Prove the load-bearing behavior live on the real surface the change touches (with the matching control skill, such as `control-cli` or `control-ui` from `cursor-team-kit`, or a named driver where none exists). Audit the diff, distrusting the PR body. Run the audit as two or more review lanes with the full brief. Give each lane one main focus, such as consumer parity with trunk, lifetimes and races, or data and config safety. **Regression lane against trunk.** Run the same load-bearing scenario on current trunk. If trunk does not have the feature, record that fact and gate the behavior the diff adds plus the end state the user waits for instead of pretending trunk can produce it. The live lane is the floor, and a verdict without it is not clean. No merge without the root's clean verdict. When the lanes return, send every proven finding against the PR to the owner in one fix-forward. A defect that a lane filed as a note is a finding. For each behavior finding, ask for a red test that covers every site with the same defect. Where no test can show the defect, ask for a repro receipt instead. Add that defect to the next round's review brief. The new head gets a fresh swarm and a fresh verdict, except for lane results that stay valid under the patch-id rule in `playbooks/shipping.md`.
-5. **On a clean verdict the owner merges and takes the next item.** The owner merges only from a head freshly rebased onto trunk. Merge prep never comes before a round's lanes start, and it ends with a rebase onto current trunk right before the merge. After the merge-prep rebase, the owner reports the new head SHA. CI must pass on that head before the merge, and the patch-id rule decides whether the round's verdict still holds. If trunk moves again before the merge, the patch-id rule in `playbooks/shipping.md` governs re-verification. A new head voids the verdict unless the patch-id is unchanged. The owner squash-merges its own PR through the resolved forge and picks up its next self-contained item from the queue. The operator's full-autonomy grant plus the root's clean verdict is the merge authorization that babysitting alone never has. Operator-named items stop at merge-ready and wait for the operator's click.
-6. **Run the root layer.** A genuinely new raise of a pinned gate or budget value (a limit CI only lets tighten) needs your fresh countersign, granted only after verifier proof. If the operator's grant or standing orders cover approvals, that countersign is the approval. The owner records it in the form that the tool's approval contract allows, with a pointer to the root's countersign. A lane checks the record against that countersign. The root never gives or bypasses an approval that the forge enforces. Absorbing values that already landed on main is drift, not a raise. Run an audit tick over all owners roughly every 30 minutes. A local root arms each tick as a real terminal `/loop`. The loop uses a monitored-shell 30-minute sleep and emits an output-notification sentinel. A cloud root uses the existing cloud-sleeper wake chain instead. Never leave the cadence to memory or lossy completion notifications. At each tick, re-read this playbook from trunk with `git show origin/main:pstack/skills/poteto-mode/playbooks/autopilot-full.md`, then re-read the armed `/goal`. Audit the operation against both. Fix drift during that tick. Probe each owner with a generic liveness or status check, and collect the decision trails. Count only side effects as progress: commits, pushes, PR or check deltas, and store reports. Treat a lane that errors, or that passes its expected runtime without a side effect, as stuck. Stand it down and dispatch a replacement at once. Do not wait for a polite return. Each tick also runs the lane stuck test over the program's agent list, where the platform has one, and over every owner's `children.tsv`. Whether or not a stop works, the root has the owner record each stuck subagent as stuck and, if its work is still needed, replace it. Each replacement that stalls gets the same steps. The root takes both steps when the owner cannot. A stall never proves or drops the work. When merges batch, run a retro pass and a post-merge bot-comment sweep. End the tick only when no delegated work is left, even after the last merge.
-7. **Stand down instantly on the operator's stop.** The operator's hold or stand-down reaches every owner as a zero-writes order immediately. Owners hold their briefs until the operator releases them.
+A verdict covers one patch and green CI covers one head. Step 4 runs a full swarm once, and again only for a major change. The patch-id rule in `playbooks/shipping.md` can carry a lane's result, and every new head needs its own green CI.

+1. **The operator's gates come first.** The grant covers only the queue's items, so items the operator names as theirs and PRs outside the queue stop at merge-ready. A request to state the plan is not a go.
+2. **Spawn one owner per PR, and keep its work where a replacement can find it.** Resolve the forge once for the program. GitHub CLI (`gh`) is the default. If `command -v origin` succeeds and Origin can resolve the repository, use `origin pr` for every PR operation. Otherwise stay on `gh` and record the fallback. Never require Graphite (`gt`). Each owner is a Cursor cloud agent that builds, opens its PR per `playbooks/opening-a-pr.md`, proves the change on the real artifact, babysits to green per `playbooks/babysit.md`, and merges once steps 4 and 5 clear it.
+
+   Open the PR early so CI and bots run alongside the work. The code is ready only after the slop-strip (the `deslop` skill from the `cursor-team-kit` plugin (`/deslop`)) and the `/no-comments` pass, so the full swarm runs on finished code. Then rebase onto current trunk and report the code-ready head before self-proof, so verification runs on the base the patch lands on. Report every later head, and merge-ready once self-proof, CI, and babysit are done. Fix rounds stay on that base unless trunk conflicts or breaks CI, because each rebase restarts CI. Run the repo's checks for the touched paths on the committed head before the code-ready push and before a later push that needs a verifier.
+
+   Assume the VM dies. Soon after starting, push and start a decision trail in the root agent's store (path in the system prompt) per the **show-me-your-work** skill, then push after every unit worth keeping. Whoever spawns a subagent records its id, state, and a stuck-after runtime from past runs of its kind in that store, so the root can probe it if the parent dies. Force-push only your own branch, with `--force-with-lease` pinned to the SHA you last pushed or took over, and on any push you did not make, stop and report to the root.
+3. **Run owners in parallel off trunk, never stacked,** so each PR lands on its own.
+4. **Swarm-verify once.** A full swarm runs once, at the code-ready head. Another full swarm runs only for new behavior, a redesign, or a large new diff. A rebase, a merge-conflict resolution, or a minor fix gets a single verifier at the new head. Fan out independent verifiers at the code-ready SHA per the **swarm** skill. They re-run the gates, prove the load-bearing behavior live on the real surface through its control skill (such as `control-ui` or `control-cli` from `cursor-team-kit`) or a named driver, and audit the diff. The verdict is not clean without the live lane, or before you audit the merge-ready report's receipts, because no lane trusts a claim it has not checked.
+
+   Send every proven finding, whatever a lane labeled it, to the owner in one fix-forward, with a red test across every site with the same defect. A defect trunk shows without the PR is recorded against trunk and does not gate the PR, but one the PR copies or newly reaches is the PR's own. Never push a fix yourself, because each branch has one writer. Replace a stuck owner instead.
+5. **The owner merges only what you verified, tested on the trunk it lands on.** Green CI alone never authorizes a merge. Once the swarm's lanes have started, merge prep rebases onto current trunk, reports the new head, and waits for green CI.
+
+   Right before merging, fetch trunk and ask whether its changes can affect the patch, because rebasing for every trunk move never ends. Rebase and wait for CI when the code that would land was never tested, as with a conflict, a file both sides changed, or a change to which checks run for the PR. A lockfile both sides changed needs no rebase when a frozen install passes on the merge result and the packages the PR changes resolve there as on the head, because that install tests the lockfile that would land, and a failing install means the rebase must repair it. When trunk changed a caller of the patch or something the patch depends on, such as code it calls or a dependency version, run the patch's checks on the merge result and merge on a pass. Otherwise merge. If trunk would force a third rebase past merge prep, hold and report to the root, which sequences the colliding work.
+6. **Run the root layer.** Anything that loosens a gate, such as a raised budget or an allowlist entry, needs a verifier's proof and then your fresh countersign, because the owner is the one who wants green. Under a grant that covers approvals, that countersign is the approval, and the owner's record of it points at your countersign for a lane to check. A disabled or soft-failed check always comes out, because it stops guarding every case. Never give or bypass an approval the forge enforces, because no countersign covers it.
+
+   On the operator's go, arm `/loop 1h` to audit until no delegated work is left, because long runs drift and agents stall silently. Each tick re-reads this playbook from trunk and fixes drift, such as an unreported head or an unrecorded agent, by having its owner record it, because drift is a gap in the record, not a stall. It probes every agent, down to the leaf lanes, and judges each by its side effects, because status text and summaries can hide a stuck child. An agent is stuck when it errors, cannot start turns, or shows nothing new past its stuck-after runtime, and so is an owner that has neither pushed nor written a trail row by the first tick. One waiting on you or the operator is not stuck, so answer it. Replace a stuck agent at once, without waiting for its stop to land. A tick that changed something for the operator ends by catching them up per the **ketchup** skill, and one that changed nothing stays quiet.
+7. **Stand down at once on the operator's stop.** A hold reaches every owner as a zero-writes order. Each reports where it stands and keeps its brief until the operator releases it.
+
+**Reply:** catch the operator up per the **ketchup** skill, covering each PR's state and verdict, what merged, countersigns and why, and open operator gates, with links to each PR and the trails.

 ### Autopilot-stack
 
-**You own the stack, never the landing. Build and verify the queue with full autonomy, then hand the operator one linear base-branch stack to review and land.** The sibling of **Autopilot-full**.
+**You own the stack, never the landing. Hand the operator one linear stack of base-chained PRs to review and land.** **Autopilot-full** holds except for how verified work leaves. Each tick re-reads both playbooks from trunk, and this one wins where they differ.
 
-1. **Run the owner loop unchanged.** Resolve the forge once for the program. GitHub CLI (`gh`) is the default. If `command -v origin` succeeds and Origin can resolve the repository, use `origin pr ...` for PR create, edit, view, watch, and merge operations. Otherwise stay on `gh` and record the fallback. Never require Graphite (`gt`). One Cursor cloud agent per PR owns its change end to end: build, first push, a ready PR opened before self-proof, self-proof (gates, CI, receipts), skeptical Bugbot triage per `../references/bugbot-triage.md`, a slop-strip (the `deslop` skill from the `cursor-team-kit` plugin (`/deslop`)), `/no-comments` (the **no-comments** skill), and babysit to green per `playbooks/babysit.md`. Owners parallelize when the work is self-contained. Within about 15 minutes, every owner starts a `decisions.tsv` trail per the **show-me-your-work** skill, pushes its first branch snapshot, and opens the PR ready, never draft. Keep the trail uncommitted and return it in the report. Owners also keep the `children.tsv` of Autopilot-full step 2.
-2. **Audit on the wake chain.** The root runs an audit tick roughly every 30 minutes. A local root arms each tick as a real terminal `/loop`. The loop uses a monitored-shell 30-minute sleep and emits an output-notification sentinel. A cloud root uses the existing cloud-sleeper wake chain instead. Never leave the cadence to memory or lossy completion notifications. At each tick, re-read this playbook from trunk with `git show origin/main:pstack/skills/poteto-mode/playbooks/autopilot-stack.md`, then re-read the armed `/goal`. Audit the operation against both. Fix drift during that tick. Probe each owner with a generic liveness or status check. Count only side effects as progress: commits, pushes, PR or check deltas, and store reports. Treat a lane that passes its expected runtime without a side effect as stuck. Stand it down and dispatch a replacement at once. Do not wait for a polite return. Probe all subagents and end the tick per Autopilot-full step 6.
-3. **Hold the operator gates.** State-then-wait, so a request to state the plan is not a go. On the operator's explicit go, arm a `/goal` with the full program objective. The goal continues across turns until the chain is done. On the operator's stop, every owner takes an immediate zero-writes hold.
-4. **Verify each round.** The owner reports its code-ready head SHA once the shipped code is final, and STACK-READY with the exact head SHA when its loop is green. The root verifies each round per Autopilot-full step 4, with STACK-READY in place of merge-ready. Nothing enters the stack unverified.
-5. **Append on a clean verdict, never ship.** No owner merges, arms auto-merge, or closes. A clean verdict appends the PR to the one linear base-branch stack, in verified order or an order the operator specified.
-6. **Single writer on topology, parallel writers on builds.** Owners push only their own branches and report the tip, current base, and intended parent. The root is the only topology writer. To append a PR, fetch the intended parent, rebase the child branch onto that exact parent tip, push with `--force-with-lease` only after an `ls-remote` check, and set the PR base to the parent branch. Create it with `origin pr create --status open --base <parent-branch>` or `gh pr create --base <parent-branch>` according to the resolved forge. Retarget an existing PR with `origin pr edit <pr> --base <parent-branch>` or `gh pr edit <pr> --base <parent-branch>`. Only the root PR targets trunk. Never submit or register the chain through `gt`.
-7. **Absorb drift at the root, then re-verify what moved.** The root fetches current trunk and rebases the chain from bottom to top. When a rebase surfaces conflicts in an owner's files, that owner fixes its own slice and the root pushes the result. A rebase rewrites every SHA above it and voids verdicts at the old SHAs. Apply the patch-id rule in `playbooks/shipping.md` at each verdict SHA. Anything that is no longer valid goes back through this playbook's step 4 before delivery. Re-run mergeability and CI after every rewritten push even when the patch-id is unchanged. The countersign rule is unchanged from Autopilot-full. A genuinely new pin raises a stop for the root's fresh countersign. Absorbing drift of landed values is not a raise.
-8. **Deliver the chain.** The deliverable is one linear chain of verified PRs, reviewable bottom-up in the resolved forge, every link carrying its verifier verdict in the PR body or a comment. The operator reviews and lands it, with their own clicks or by arming merge-when-ready.
+1. **Run Autopilot-full's owners, minus the landing.** Owners report STACK-READY in place of merge-ready. They never rebase onto another branch, trunk included, and never retarget, merge, close a PR, or arm auto-merge, because the root owns the chain's topology and the operator owns the landing. When an item depends on another, its owner branches from that item's branch, not from trunk.
+2. **Give the topology one writer.** Owners push only their own branches and report each tip and its intended parent. Only you rebase or retarget a link, because two writers on one chain undo each other. Append each clean PR in dependency order, with its base set to its parent's branch (`origin pr edit <pr> --base <parent-branch>` or `gh pr edit <pr> --base <parent-branch>`). Never require `gt`. An owner takes your push as its new base and lease, and on a conflict resolves its own slice for you to push.
+3. **Absorb drift at the root.** Until landing starts, apply Autopilot-full step 5's test to each link and rebase the chain bottom-up where it calls for one. Then apply the patch-id rule link by link, since a link's base is its parent.
+4. **Deliver the chain, then keep your hands off it.** Each link carries its verdict in its PR. Once landing starts, nobody writes to the chain except the post-merge retarget that `playbooks/shipping.md` sanctions, because a second writer breaks a landing in flight. A mid-landing problem goes through you to the operator, and any fix waits for the operator's go.
 
 **Choosing between the autopilots.** Autopilot-full when the PRs are independent and landing authority is granted. Autopilot-stack when the operator wants review before landing, the work is sequenced or coupled, or merge authority is withheld.

Report that frontier merge-ready and stop the watcher. Do not leave it running until merges happen. That is Shipping's job. If another actor merges the frontier and the watcher reports `ADVANCE`, continue with the new frontier. `COMPLETE` is terminal if another actor finishes the queue.
 
-   Watcher re-arms never authorize merging or arming merge-when-ready. Do not run `origin pr merge` or `gh pr merge` unless the user explicitly asked to merge, land, ship, or merge when ready. Route that request to `playbooks/shipping.md`. A stacked PR whose parent has no required checks may merge immediately into that parent when merge-when-ready is armed. This collapses review granularity. A lost-ref race can also mark it merged without updating the parent ref.

    Answer a user question mid-loop and continue. Only an explicit stop ends the loop before the active forge's stop condition. On GitHub, that is `READY` in single or stack mode, or a `WAITING`/`merge-queue` report or `COMPLETE` in queued mode. On Origin, that is the merge-ready state defined above. For a GitHub queued stack, capture the PR list bottom-to-top once and pass the same frozen list to every rearm. Revise the list only for the sanctioned follow-up PR from step 4. Append it at the end, drop the merged owner, and rearm with the corrected snapshot.
 7. **Classify CI before any retrigger.** Flake or infrastructure earns one fresh build, never a job retry. One retry only. An identical second failure means it was never flake, so reclassify and read the child logs instead of retrying blind. A failure in code the diff never touches means a stale base, so check with `git merge-base --is-ancestor` before assuming flake. Report a stale base as needing a rebase instead of burning retries. Only a failure in the diff's own code gets a commit.
 8. **Bugbot is triaged skeptically, always.** Verify each claim against the code per `../references/bugbot-triage.md`. Fix real findings with a red-first proof in the lowest PR that owns the code, never at the tip unless the owning PR has merged. In that case, use step 4's sanctioned follow-up PR. Per step 2, upstack fixes wait for step 5's next frontier-driven push wave. Push that wave before replying so the reply cites the commit. On Origin, reply with `origin pr thread reply <thread-id> <pr> --body-file <reply-file>`. On GitHub, call `gh api --method POST "repos/<owner>/<repo>/pulls/<pr>/comments/<comment-id>/replies" --input <payload.json>` and put the reply body in the JSON file as data. Never interpolate comment text or a reply into a shell command. Dismiss noise with the concrete disproof on the thread. On GitHub, use the watcher's Bugbot pass count. On Origin, derive the pass count from `origin pr thread list` and the review history. From the third pass on, lean toward dismissing documented patterns, still escalating anything touching security, auth, billing, data, or migrations rather than dismissing it yourself. Never churn code to quiet a bot.
 9. **Stop at the human's line.** Owner approval is a wait, not a blocker to fix. Babysitting never authorizes merging. Only an explicit request to merge, land, ship, or merge when ready does. Route that request to Shipping. Surface the escalation and keep working the rest. After GitHub reports `READY`, a queued `WAITING`/`merge-queue` stop, or `COMPLETE`, or after Origin reports the frontier merge-ready, sweep the run's triage decisions once. Offer any team-useful dismissal pattern as a candidate entry in the shared rubric (`../references/bugbot-triage.md`) and its own PR. Never keep it only in private memory.
 
 `drive` ends at merge-ready. Landing the stack is `playbooks/shipping.md`.

Then fix one metric, the direction that counts as better, and a checkable stop predicate that pairs a target with a floor on attempts so a lucky early win can't end the run (the example "at least 50% better than baseline and at least 10 iterations" is this shape). Use the user's numbers when given, otherwise agree them.

 - **Sub-coordinator.** Always local, durable, one per track, and only when the program exceeds what one coordinator's drains can manage. A track the coordinator can drain itself needs no middle layer. Each nested layer re-pays a full orientation preamble, and a blocking sub-coordinator hides its children while the parent idles. Owns its track's units and boards, authors its workers' briefs, spawns its own workers and verifiers (nesting works to depth 3, and a nested spawn has the full Task schema including `environment`). Rolls up aggregates at wave boundaries. Never forwards raw child reports. Cap in-flight children at what one drain can process, roughly ten, as a rolling window. Never as blocking batches, which cost the slowest child of every batch.
 - **Worker / verifier.** Always `environment: "cloud"` unless the task needs this machine: `control-ui` or `control-cli` runtime verification (from `cursor-team-kit`). Reading local transcripts under `agent-transcripts/`. Simulators and local IDE state. Auth that exists only here. Cloud agents cannot read the local store, so their briefs inline what they need or point at repo paths. Prefer fewer, broader workers. One writer per worktree or branch (principle-separate-before-serializing-shared-state). Run a unit's verifier on a different model family from its worker.

 #### Steps
 
 1. **Frame.** State the done predicate as something countable ("all 126 units merged, each ledger-verified `unit-test-verified` or better"). Quantify scope: units, rough effort, expected stacks, and the wall-clock budget. If one agent could finish inside that budget, stop here and run Autonomous run instead. Collapsing must not depend on another document being present. It means do the work directly in this session, plain workers where they help, verification inline, landing as you go, and none of the store, register, or pilot machinery below. Schedule landing against the budget. By roughly 70% of it, stop spawning and land what is verified. Name the tracks per project. A contested decomposition or one-way door goes through the arena skill before the pilot. Present the framing once. Reversible prep proceeds without waiting.

 3. **Pilot.** Push one unit through the whole path: brief, worker, verification, stack entry, ledger row, merge. The pilot exists to falsify the brief template, the verify recipe, and the unit size while that costs one agent instead of fifty. Fix the contract from pilot evidence before any fan-out. Scale the pilot to the unit. On programs of near-identical cheap units, the first unit is the pilot, run as a normal unit with its verify command inline, and fan-out starts the moment it lands. The dedicated pilot pipeline (separate verifier agent, audit gate) is for expensive or novel unit shapes, not for clone-units where a serialized pilot has nothing to falsify.
 4. **Scale.** Spawn a rolling window of workers up to the in-flight cap, refilling as children finish. Blocking batches pay the slowest child of every batch. Spawn track sub-coordinators only past the one-drain threshold in Roles. Recompute ready work after each drain. Relay upstream reports into downstream briefs. Keep sibling communication upward only. The sampled brief audit runs alongside the wave it samples and stops the next refill on failure, not the current one.
 5. **Drain.** Run the queue discipline below at every drain point.

 2. `how` to ground hypotheses. Don't claim a perf ceiling without running it first.
-   Most fixes come from eight strategy families. Use them as hypothesis generators, not a checklist. A family earns an attempt only when the trace shows the signal it names.
-   - **Elimination.** Before optimizing the hot path, ask whether it needs to exist: a computation nobody consumes, a feature gate that's always off for this user, a sync that redundantly mirrors state, a legacy path kept "just in case". The trace shows what's slow, never that it's deletable, so this family needs the `how` pass, not the profiler.
-   - **Divide and conquer.** The dominant cost scales with input size. Split the work so each piece touches less (chunk, shard, prune the search space) or so independent pieces run in parallel.
-   - **Caching.** The same computation or fetch repeats on identical inputs. Store and reuse the result. Name what invalidates it before claiming the win.
-   - **Indirection.** The hot path does expensive work a cheaper intermediate could absorb: an index instead of a scan, a queue that shifts work off the interactive thread, a handle that lets a cheaper implementation swap in. Add the hop only when it removes more from the critical path than it adds.
-   - **Batching.** Many small operations each pay a fixed overhead (RPC, query, syscall, draw call). Coalesce them to pay the overhead once per batch.
-   - **Redundancy.** The wait hangs on one slow instance or attempt. Duplicate the work (replicas, hedged requests, speculative execution) and take the fastest result. The trace has to show the wait dominates and the system has headroom.
-   - **Lazy evaluation.** Cost lands on results that are never used or not needed yet (eager init on the boot path, rendering offscreen items). Defer the work until first use.
-   - **Scheduling.** The work must happen, but not during the interactive moment. Move it to where nobody is waiting: idle callbacks, a background warmup after boot, precompute before the user arrives, cleanup after the frame commits. The win is perceived latency, so measure the interactive path, not total work done.

-**You own what lands. Verify each PR independently, land only the verified run from the root, then keep your hands off the queue.**
+**You own what lands. Verify each PR independently, land only the verified run from the root, then keep your hands off the stack.**
 
-This is the half after `playbooks/babysit.md`.
+1. **Resolve the forge, then verify each PR independently before it lands.** GitHub CLI (`gh`) is the default. If `command -v origin` succeeds and Origin can resolve the repository, use `origin pr` for every PR operation. Otherwise stay on `gh` and record the fallback. Never require Graphite (`gt`). One verifier per PR, each a Cursor cloud agent, runs the change the way a user would with the matching control skill (such as `control-ui` or `control-cli` from `cursor-team-kit`), parent against head, and posts `PASS`, `PASS+NOTES`, or `FAIL` on that PR. Only a verdict from an agent that did not write the code counts, because an author checks what it meant to build. Green CI and an approving bot review are not verdicts, because neither runs the change as a user would.
+2. **Land only the contiguous verified run rooted at the bottom.** Walk up from the lowest unmerged PR and stop at the first one without `PASS` or `PASS+NOTES`. The PRs below it are the run, and the top one is the ceiling. A verified PR above an unverified one waits, because it cannot land without the code below it. One whose branch neither holds nor needs that code can move onto trunk and land on its own. It needs a fresh verdict first, because its old one ran with that code beneath it and trunk does not have it.
+3. **Re-check that the verdicts still describe the code.** A verdict covers a patch, and a chain rebase moves every PR above it to a new SHA without failing any check. Compare `git patch-id` at the verdict SHA with the current head before trusting an older verdict. When the patches differ only in tests, docs, or lint config, a lane's result stands if what it ran builds the same at both SHAs apart from noise. Noise is a difference that also shows up between two builds of the verdict SHA, or an embedded commit SHA. Report each kind of noise with its files, so a reader can check the call. The change itself still gets fresh checks and a review, because the old verdict never saw it. A lane with no build output, such as a dev server, cannot show this, so rerun it, and re-verify anything else that drifted.
+4. **Land bottom-up, one PR at a time.** Always merge the run's lowest unmerged PR, with `origin pr merge <pr>` or `gh pr merge <pr> --squash`. On Origin the plain command also merges every PR below the one you name, and on GitHub a PR whose base is still its parent's branch merges into that branch, not trunk. Read the PR back for the result (`origin pr view <pr>` or `gh pr view <pr> --json state,mergedAt,baseRefName`), because a merge command can report success when a merge queue only queued the PR, and a requested auto-merge is not a merge. A landed PR reads merged with trunk as its base, not its parent's branch. Arm `--auto` (Origin merge-when-ready or GitHub auto-merge) only on a PR whose verdict covers its current head, because it lands whatever head is ready. After a merge lands, retarget the PR whose base was the merged branch to trunk (`origin pr edit <pr> --base <trunk>` or `gh pr edit <pr> --base <trunk>`), move its patch onto the merge result, and push with `--force-with-lease`. The verdict covers the patch, not its commits, so step 3's patch-id rule decides whether the verdict survives. Merge it once its checks pass and its verdict survives.
+5. **Leave the stack alone while it lands.** Step 4's move of the next PR is the only change to a branch or base, because a merge lands whatever its branch and base hold at that moment, verdict or not. On GitHub, watch the run with the queued watcher from `playbooks/babysit.md` (`scripts/watch-pr/watch-pr --queued-stack --stack-prs <bottom-to-top>`) under `/loop` until it reports `COMPLETE` at the ceiling. On Origin, re-read the current PR with `origin pr view <pr> --checks` each time `origin pr checks <pr> --watch` returns, until the ceiling reads merged. A base that moves to trunk when its parent merges is expected, not damage to repair. If a merge stalls, find out why before you change anything.
+6. **Stop at the ceiling.** Extending the run takes new verdicts, so it is a new pass through step 1.
 
-1. **Resolve the forge, then verify every PR independently.** GitHub CLI (`gh`) is the default. If `command -v origin` succeeds and Origin can resolve the repository, use `origin pr ...` for PR view, watch, edit, and merge operations. Otherwise stay on `gh` and record the fallback. Never require Graphite (`gt`). One subagent per PR, not batched, each a Cursor cloud agent, each exercising the real surface with the matching control skill (such as `control-ui` or `control-cli` from `cursor-team-kit`) against parent versus head. Each returns `PASS`, `PASS+NOTES` or `FAIL` and posts that verdict on its own PR. Safe means a verdict from an agent that did not write the code. CI green is not a verdict, and an approving bot review is not a verdict.
-2. **Land only the contiguous verified run rooted at the bottom.** Walk up from the lowest unmerged PR and stop at the first one without a passing verdict, where both `PASS` and `PASS+NOTES` pass. A verified PR sitting above an unverified one is not landable. Report the ceiling as a PR number and say what breaks the chain.
-3. **Re-check that each verdict still describes the patch.** Record the verdict head SHA, base SHA, and stable `git patch-id` of that PR's base-to-head diff. A rebase or base retarget rewrites SHAs and can silently invalidate a verdict without touching a check. Before landing a PR, compare the recorded patch-id with its current base-to-head patch-id. When the two patches differ only in tests, docs, or lint config, build what each lane ran. Build it twice at the verdict SHA and once at the current head. A difference is noise if the two builds at the verdict SHA also show it, or if it is an embedded commit SHA. Judge each difference, not each file, and report each kind of noise with its files. If only noise differs, that lane's result stays valid, and checks and a review of the change run fresh. Do not reuse a lane result from a dev server or from anything else with no build output. Rerun that lane. Re-verify anything else when the patch changed. When it did not, keep the code verdict but re-run mergeability and CI at the current head. Never use matching commit messages or a green check from an older SHA as a substitute.
-4. **Prepare only the bottom PR.** Fetch current trunk. Rebase the lowest verified branch onto the exact trunk tip when needed, push it, and retarget only that PR to trunk with `origin pr edit <pr> --base <trunk>` or `gh pr edit <pr> --base <trunk>`. Re-run step 3 after the push. Do not retarget, arm, or merge descendants yet.
-5. **Land one PR at a time.** If the bottom PR is mergeable now, squash it with `origin pr merge <pr> --squash` or `gh pr merge <pr> --squash`. If requirements are still running and the user asked for merge-when-ready, arm only that PR with `origin pr merge <pr> --squash --auto` or `gh pr merge <pr> --squash --auto`. Origin's `--auto` is Origin merge-when-ready. GitHub's `--auto` is GitHub auto-merge. Wait for that PR to merge before preparing the next one.
-6. **Do not read GitHub `autoMergeRequest` as stack readiness.** At most it says GitHub auto-merge was requested for one GitHub PR. It does not prove Origin merge-when-ready is armed, that a descendant is queued, that a patch verdict is current, or that the contiguous stack is safe. Confirm the active forge's state for the current bottom PR, and say that the state is unknown if the active forge cannot report it.
-7. **Recompute after every merge.** Fetch trunk, confirm the merged SHA is present, drop the merged PR from the frozen bottom-to-top list, and inspect the new bottom PR's base, head, checks, and patch-id. A host may retarget a child automatically, but do not assume it did. Repeat steps 3 through 6 for that one PR. Independent work stays outside this chain and ships on its own.
-8. **Watch the current frontier until it merges or fails. Do not mutate the queue around it.** With Origin, use `origin pr view <pr> --checks --comments` and `origin pr checks <pr> --watch`, then re-read the PR until it reports merged or blocked. With GitHub, use `scripts/watch-pr/watch-pr --queued-stack --stack-prs <bottom>` only as an event wake and poll `gh pr view <pr> --json state,mergedAt,mergeStateStatus,statusCheckRollup,autoMergeRequest` after each wake, ignoring `READY` until `mergedAt` is non-null or `state` is `MERGED`. Only then run step 7. Hard-fail only when `state` is `CLOSED` with no `mergedAt`, a required check concludes `FAILURE` or `CANCELLED` and blocks merge after auto-merge is no longer pending, or `mergeStateStatus` is `UNSTABLE` or `DIRTY` with no auto-merge pending. `BLOCKED` while checks are pending or auto-merge is armed is not failure. Do not use Babysit's queued `WAITING`/`merge-queue` stop condition here. Hold the watch under `/loop` in dynamic mode. Report each merge and the new ceiling. If the queue stalls, diagnose before mutating.
-9. **Stop at the ceiling.** When the verified run is merged, report what landed, what the next unverified PR is, and what verifying it would take. Extending the run is a new pass through step 1.

 ### Worktree and simulator cleanup
 
-**You own the disk and the safety gate.** Prune merged or abandoned git worktrees and stale iOS simulators to reclaim space. Deletion is irreversible, so every step guards against deleting something in use or holding uncommitted work.

-1. Snapshot and audit. Record `df -h /`, then run `scripts/worktree-audit.sh` (principle-build-the-lever). It reads paths from `git worktree list`, never hand-typed, since a hand-typed `myrepo-worktrees/x` misses one that lives at `.cursor/worktrees/myrepo/x` (principle-encode-lessons-in-structure). It classifies each worktree by size, age, merge state, uncommitted work, PR state, and the newest chat that touched it, then suggests a bucket. The transcript scan is slow, so background it.
+1. Snapshot and audit. Record `df -h /`, then run `scripts/worktree-audit.sh [-b <pr-base-ref>] [repo-path]` (principle-build-the-lever). Without `-b` it checks `MERGED` against `origin/HEAD`, so pass `-b origin/<branch>` when PRs target another branch. It reads paths from `git worktree list`, never hand-typed, since a hand-typed `myrepo-worktrees/x` misses one that lives at `.cursor/worktrees/myrepo/x` (principle-encode-lessons-in-structure).

 2. The bucket is advice, not permission. The pinned and active chats are the real artifact (principle-prove-it-works). Get that set from the user or sidebar and cross-check every candidate. The lever has marked `safe` a worktree the user had pinned, so the pinned set wins.
-3. Verify usage before deleting. For every `verify-recent-chat` row, or anything you doubt, fan subagents out to read the transcripts and report whether the chat is pinned or ongoing and which worktrees it touches (principle-guard-the-context-window, transcripts are bulk). A pinned chat spawns arena and repro trees into sibling worktrees via background subagents, and those are in use even when their names never hit the sidebar.

Pick each subagent's reasoning level and fast or standard speed for the job, per the Subagents section.
 4. Pause on irreversible loss. `wip:N` is N tracked uncommitted edits. Show the diff and get a decision first, since removing a clean worktree is recoverable from its branch but uncommitted work is gone. `scratch:N` is untracked throwaway, safe to drop, but name the files. Per Autonomy, clean and merged and not-in-use proceeds. `wip` and in-use pause.
 5. Prune the confirmed set. Per path, `git worktree remove --force <path>`. If the dir survives on ignored build artifacts, `rm -rf` it, then `git worktree prune`. Branch refs survive, so no commits are lost. Confirm with `df -h /` and re-list.
 6. Simulators and other reclaimers. Simulators are usually the next-biggest win. `xcrun simctl --set testing delete all` (XCTestDevices clones), `xcrun simctl delete unavailable`, and `xcrun simctl runtime list` then `runtime delete <id>` for old runtimes. More when needed: Xcode `DerivedData` and `iOS DeviceSupport`, `~/Library/Application Support/Cursor` (`state.vscdb.backup`, and `snapshots/roots/<root>` where a `<root>` named for a folder you opened as a workspace balloons), package caches (pnpm, uv, brew, yarn). Clear only caches the user has not said to keep.

 When two or more fixes that share one premise have failed the same gate, suspect the premise, not the fixes.
 
-**Why:** Each failure under a shared premise is evidence about the premise.
+**Why:** Each failed fix is evidence against the belief it assumed. A third fix on the same premise spends effort where the evidence already says the cause is not.
 
 **Pattern:**
 - **Write the premise down.** The premise is the one sentence that every failed fix assumed.
-- **Take a census before the next fix.** Count the imbalance per actor. The census shows which actors hold the imbalance, not how large it is. Write the census as a rerunnable script per [Build the Lever](../principle-build-the-lever/SKILL.md).
-- **Read the skew.** If the same few actors hold most of the imbalance on every run, something assigns them that role. Find what assigns the role. That assignment is the next "why" per [Fix Root Causes](../principle-fix-root-causes/SKILL.md).
-- **Remove the asymmetry instead of compensating for it**, per the [Laziness Protocol](../principle-laziness-protocol/SKILL.md). Rotate the role between actors, randomize the assignment, or move the role, so that no actor holds it on every run. A return path, a shared pool, a batched hand-off, or a periodic rebalance leaves the assignment in place and adds work on every run.
+- **Test the premise before the next fix.** Find an observation that would come out differently if the premise were false, and make it. Look at how the failures are distributed, not only at how large they are. Make the check rerunnable per [Build the Lever](../principle-build-the-lever/SKILL.md).
+- **Follow the evidence.** If it contradicts the premise, the cause is elsewhere. Look for what the failures have in common that the premise did not predict. If it confirms the premise, ask the next "why" per [Fix Root Causes](../principle-fix-root-causes/SKILL.md). The earlier fixes may have treated a consequence instead of the cause.
+- **Remove the condition instead of compensating for it**, per the [Laziness Protocol](../principle-laziness-protocol/SKILL.md). If the evidence shows that one part always lands on the losing side, change what puts it there. A mechanism that cleans up after it leaves the cause in place and adds work on every run.
 
-**Stop:**
-- Do not start the next fix before the premise is written down and the census exists.
-- If the census is even across actors, the premise is not the cause. Look for the cause elsewhere and keep the census as evidence.
+**Stop:** Do not start the next fix before the premise is written down and tested.
 
 This principle is distinct from [Redesign from First Principles](../principle-redesign-from-first-principles/SKILL.md), which rebuilds a design around a new requirement. It questions a fact the current design assumes.

 # Encode Lessons in Structure
 
-Encode recurring fixes in mechanisms (tools, code, metadata, automation) instead of textual instructions. Every error, human correction, and unexpected outcome is a learning signal. Capture it, route it, and close the loop.
-
-**Why:** Textual instructions are easy to miss. They require the reader to notice, remember, and comply. Structural mechanisms (lint rules, metadata flags, runtime checks, automation scripts) enforce the rule without cooperation.
-
-**Pattern:**
-When you catch yourself writing the same instruction a second time:
-1. Ask: can this be a lint rule, a metadata flag, a runtime check, or a script?
-2. If yes, encode it. Delete the instruction
-3. If no (requires judgment), make the instruction more prominent and add an example of the failure mode
-
-**Pick the strongest mechanism.** When more than one mechanism would work, choose the strongest the situation allows (an unrepresentable state that cannot compile, then a lint or banned API that fails CI, then a canonical helper, then a runtime check), because agents copy whatever the surrounding code already does and a weaker guard becomes the next template.
+If the lesson needs judgment and cannot be encoded, make the instruction more prominent and add an example of the failure mode.
 
 **Corollary:** If the fix is structural, only use the structural fix. The instruction is the symptom.
-
-**Feedback loop:**
-- **Capture every correction.** When the human intervenes or tests fail, decide if it's a one-off or a pattern.
-- **Route to the right layer.** One-off -> brain note. Recurring fix -> skill or lint rule. Systemic issue -> principle.
-- **Close the loop.** Don't just record. Apply now or create a concrete todo.
-
-**Anti-patterns:**
-- Acknowledging without recording ("I'll keep that in mind" does not persist)
-- Recording without routing (a brain note about a lint rule that should exist is wasted unless the lint rule gets implemented)
-- Fixing without generalizing (fixing one instance while leaving the recurring pattern intact)

 # Make Operations Idempotent
 
-Design operations so they converge to the correct state regardless of how many times they run or where they start from. Every state-mutating operation should answer: "What happens if this runs twice? What happens if the previous run crashed halfway?"
+Design operations so they converge to the correct state regardless of how many times they run or where the previous run stopped. Every state-mutating operation should answer: "What happens if this runs twice? What happens if the previous run crashed halfway?"
 
 **Why:** Commands, lifecycle operations, and processing loops run where crashes, restarts, and retries are normal. If partial state changes the next run's outcome, every restart becomes a debugging session.
 
-**The pattern:**
-- Convergent startup: scan for existing state, clean stale artifacts, adopt live sessions
-- Content-based cleanup: compare by content equivalence, not creation order
-- Self-healing locks: use PID-based stale lock detection
-- Idempotent scheduling: failed work respawns cleanly, fresh input regenerated after each cycle
+**The idea:** derive each step from the state that exists, not from what the previous run meant to do. Read the current state, compare it to the goal, and apply only the difference. A step written this way is safe to repeat, because a repeat finds nothing left to do.
+
+Anything a run leaves behind, such as a lock, a temporary file, a half-written record, or a claimed job, must be recognizable as stale by the next run. Judge staleness by evidence that stays true wherever the previous run could have stopped, not only in the common case. A marker that the next run cannot judge turns every crash into manual cleanup. For example, write to a temporary path and rename it into place, or compare artifacts by content instead of by creation order.
 
 **The test:**
 1. What happens if this runs twice in a row?

-- Do not keep legacy API paths only because internal callers still exist
-- Inventory callers, migrate them, and delete the old API immediately
-- Treat temporary adapters as exceptional and time-boxed, not default architecture

 - No external users depend on backward compatibility
 - The project can absorb coordinated breaking changes
 - The new API is part of a simplification or refactor initiative

 # Test Behavior, Not Implementation
 
-A test calls the code the way its users do and asserts the result they observe against a literal expected value. A test that asserts which calls the code made, or restates a constant the code contains, does neither.
+A test is a claim about what the code does for its users: a caller, an end user, or another service. Behavior is what those users can observe through the interface they use. That includes return values, errors, state they can read back, and effects on systems outside the code, such as a request sent, a row written, or a message emitted. Implementation is what they cannot observe: private helpers, internal call order, intermediate data, and which internal collaborator did the work.
 
-The check: before you keep a test, ask whether it would still pass if every function it imports returned `undefined`. If yes, it observes no behavior and cannot fail for a defect. Rewrite the assertion or delete the test.
+Judge each test against two imagined edits:
 
-**Why:** A test that cannot fail for a defect costs CI time and review attention and catches nothing. A constant pin also fails when someone edits the constant or the prompt it restates, so it prevents that edit.
+- **Break the behavior.** Make the code return a wrong value, skip an effect, or do the effect twice. If the test still passes, it proves nothing. The usual causes are an assertion looser than the contract, an expected value computed by the code under test, a restated constant or prompt string that never runs the code that reads it, and an assertion on data that the test built itself.
+- **Change the internals.** Keep every observable result the same and restructure the code underneath. If the test now fails, it is pinned to the implementation. It will need a rewrite on every refactor and still catches no bug.
 
-**Five shapes that still pass when every imported function returns `undefined`:**
+Keep a test that catches the first edit and survives the second. Rewrite or delete the rest. To write a test that does both, drive the code through its users' interface with a concrete input. Derive the expected value from the requirement, not from a run of the code. Assert what the contract promises, no less and no more.
 
-- **Weak or no assertion.** No `expect`, or only `toBeDefined`, `toBeTruthy`, `not.toThrow`, `toBeInstanceOf`, `toBeGreaterThan(0)`.
-- **Mock or absence only.** Only `toHaveBeenCalled`, `not.toHaveBeenCalled`, `toBeUndefined`, `toEqual([])`, `toHaveLength(0)`, `not.toBe(wrongValue)`.
-- **Self-referential.** The expected value comes from the code under test: `expect(f(a)).toBe(f(a))`, `expect(parsed.url).toBe(buildUrl(...))`.
-- **Constant pin.** The assertion restates a hand-maintained constant, config default, table row, or prompt string: `expect(LIMITS.maxTools).toBe(8)`, `expect(PROMPT).toContain("You are")`.
-- **Fixture asserts fixture.** The assertion reads data the test built or a value computed in `beforeEach`, and the subject never runs inside the body.
+The contract decides, not the shape of the assertion. When "an empty cart never charges" is the promise, an assertion that the payment client got no call is behavior. Pair it with a case where the charge happens, so that the test shows it can see a call. The payload that a mocked external service receives is behavior, because that service observes it. A call to an internal helper is implementation, because no user can see it. An empty list is the exact answer when no record matches, and a hollow check when the test only needs some result. An exact error message pins wording that no caller reads. The error type that callers branch on is the contract.
 
-**The fix:** call the subject inside the test body with one concrete input and assert the literal output or the observable effect, `expect(slugify("Hello, World!")).toBe("hello-world")`. For an absence, assert the presence on the other input in the same test. For a constant, test the mechanism that reads it with one input instead of restating the value. For a mock, assert the payload it received or the state after the call, not that it was called. When no such assertion exists, delete the test.
-
-**Keep** a test of a relation across a table's rows (a key present in two tables, a parent that exists), and a compile-time check in a `*.test-d.ts` file.
+A test can pin an invariant instead of a call, such as a key that must exist in two tables or a compile-time type check. The invariant is the behavior.

 # Type System Discipline
 
-The type checker is a proof assistant. Use it to eliminate impossible states, mismatched primitives, and unhandled variants at compile time. A case the types let you ignore becomes a runtime failure the compiler could have stopped. Prefer defining errors and special cases out of existence over proliferating handlers. Unrepresentable states, total functions, and interface redesign (the patterns below) are the tools.
+Make the compiler reject impossible states, mismatched primitives, and unhandled variants. Prefer defining errors and special cases out of existence over proliferating handlers. For TypeScript syntax, see the `typescript-best-practices` skill.
 
-Applies to any typed language. Skills like `typescript-best-practices` ground it in specific syntax.
-
-**The patterns:**
-
-- **Make illegal states unrepresentable.** Model variants as sum types: discriminated unions in TypeScript, enums with payloads in Rust/Swift/Kotlin, sealed classes in Scala, ADTs in Haskell/OCaml. Don't model state as a bag of optional fields where contradictory combinations compile. A subtle anti-pattern: `{ completed: boolean; completedAt?: Date }` admits `completed: true; completedAt: undefined`, which is meaningless. Derive the boolean from a single source like `completedAt !== null`, or model the variants explicitly as `{ kind: 'open' } | { kind: 'done'; at: Date }`. If a bug forces the question "wait, can this combination actually happen?", the type is too loose.
-- **Types are constructions, not restrictions.** Build the type up from the values you want instead of carving them out of a looser type with checks. The invariant that seems to need a refinement type is usually a construction away. A non-empty list is a head plus a rest, not a list with a length check. A valid time range is a start plus a duration, not two timestamps you must keep ordered. No representation is privileged. A list of pairs is an even-length list if you interpret it that way, so choose the shape that cannot build the illegal value and expose the interface callers need on top.
-- **Brand semantic primitives.** `UserId` and `OrderId` are strings underneath but should not be interchangeable. Newtypes in Rust, opaque types in Swift, value classes in Kotlin, phantom types in Haskell, branded intersections in TypeScript. Validate once at creation, trust the type downstream.
-- **External data is untyped until parsed.** RPC payloads, JSON, IPC messages, CLI args, config files, environment variables, database rows. Have a parse function at every boundary that turns unstructured input into the typed model. See the **boundary-discipline** principle skill for where to put validation.
-- **Don't lie to the type system.** Casts, unsafe coercions, and assertion functions that bypass the compiler are latent runtime crashes. If the compiler can't prove a fact, prove it (validate, narrow, refine the model) or accept that the cast is a hazard.
-- **Exhaustive matching is the compiler's job.** When you match on a sum type, the compiler must fail compilation if a new variant is added without handling. Use the idiom your language provides: `never`-typed binding in TypeScript, unannotated `match` in Rust, `-Wincomplete-patterns` in Haskell, sealed-class match exhaustiveness in Kotlin.
-- **Derive types from authoritative schemas.** When a protocol buffer, OpenAPI spec, GraphQL schema, database migration, or design-system token file defines a shape, derive from it instead of hand-rolling a parallel type. See the **encode-lessons-in-structure** principle skill.
-- **Strengthen a type only where partiality appears.** A runtime assertion, null check, or "this should never happen" throw marks the place a type is too weak. Push that check up into the type. Then stop. The type system's job is to track the cases each use site must handle, not to describe the data as precisely as possible. Prefer total functions. `sum` of an empty list is 0, so it takes the plain list. `head` of an empty list has no answer, so it demands the non-empty one.
-
-**The tests:**
-
-- "Can I write a comment explaining when this combination of fields is valid?" If yes, the type is too loose. Split it into a sum type.
-- "Do two of my function arguments share a primitive type but mean different things?" Brand them.
-- "Where did this `any`, this `as`, this `assertNotNull` come from?" Trace it to the boundary and validate there instead.
-- "If a new variant is added next month, will the compiler tell the next agent where to add a case?" If no, the match isn't exhaustive.
-- "Is this type duplicating a shape another file owns?" Derive instead.
-- "Am I strengthening this type to keep an operation total, or just to be more precise?" If nothing would otherwise panic, keep the plain type.
+- **Brand semantic primitives.** `UserId` and `OrderId` are strings underneath but should not be interchangeable. Give each its own type, such as a branded intersection in TypeScript or a newtype elsewhere. Validate once at creation, trust the type downstream. If two arguments share a primitive type but mean different things, brand them.
+- **External data is untyped until parsed.** RPC payloads, JSON, IPC messages, CLI args, config files, environment variables, database rows. Have a parse function at every boundary that turns unstructured input into the typed model. The **boundary-discipline** principle skill says where to put validation.

 1. Classify, then route. One specific prior chat to resume is the `session-pickup` playbook, not this. Turning habits into a durable skill is `automate-me`. A human-readable summary of your work is a different task. Recall loads working context across recent chats before you act. If the user already gave you a full state capsule (paths, branch, the change), use it and skip the mining.
 2. Lock the scope before searching. Pin the window ("recent" is a real range, default the last 7 days), the topic if named, and the workspace (default the active one. Never read another project's transcripts without being asked). State the scope back. Never quietly turn "all" into "recent N".
-3. Fan out across your chat history. Spawn parallel subagents on a fast, cheap model, each taking a slice of the corpus. Tell every subagent to order candidates by real modification time (`ls -t`) and never by UUID name, grep the topic first and then read only the matching chats and only their relevant regions, and skip the current chat plus obvious noise (subagent, eval, and test chats). Each returns the same schema, one block per chat: topic, the user's goal, decisions, open threads, struggles and corrections, and artifacts (PRs, tickets, branches), each citing the chat UUID. For one or two chats, skip the fan-out and search directly. The raw transcripts stay in the subagents. The main thread gets only their findings.

 4. Sweep the shared record whenever the topic names a feature, file, subsystem, area, or bug. This is the default, not a judgment call, and "my work on X" does not exempt it. Hand it to the **why** skill's source investigators, but steer their question from "why was this built this way" to "what's the current state, what's been tried and didn't hold, and what are users still reporting". Reuse its per-source playbooks, run the investigators in parallel with the chat-history mining, and inherit its posture: one investigator per source, null results are findings, skip an unavailable MCP and say so. Fold what comes back into the brief. Skip this step only for pure activity recall with no named target ("what did I do this week"), where your own history and live state are the entire answer.
 5. Verify against live state. Take the PRs, branches, and tickets that the mining and the sweep surfaced and check them with `git` and `gh`. When the answer hinges on what an agent actually did (the tools it ran, files it read, errors it hit), read the full transcript, not just a trimmed local copy.

 - Overly wide source type (e.g. `Record<string, unknown>`): narrow it.
-- Untyped boundary: add a parse function or schema.
+- Untyped boundary: parse with the schema that owns the shape. Add a schema only where none exists.

-14. **Colon overuse.** Colons are fine before a list or example. Not as mid-sentence connectors.

 ### Plain speech
 
 27. **Say what it does, not how it feels.** "the database stays close at hand", "SQL you can read", "types that follow your schema" name a feeling. The fix names the mechanism or a number: "`.toSQL()` returns the exact string sent to the database", "a column rename fails the build". Ask what the sentence tells the reader to do or know, then write that. If you can't restate it as a concrete instruction, fact, or number, cut it. One more check: if the sentence could appear unchanged in another project's docs, it says nothing about this one. Cut it.
 28. **Shorten or split dense sentences.** If the reader has to backtrack to parse a sentence, break it in two or drop clauses. One idea per sentence.
 29. **Active voice.** Prefer it. Catch "is/are/was/were + past participle" and name the actor: "queries are validated" becomes "the compiler validates queries", "the file is parsed by the loader" becomes "the loader parses the file".

 33. **Over-compression.** Dropped articles, verbless fragments, symbol-speak, and abbreviations that make the reader decode instead of read.

+The **target** is usually a chunk of code, a pattern, a feature, or a named design decision. The **question** is usually a design rationale, a tradeoff, a motivating edge case, an external constraint, dead code, or a broad history sweep.
 
 If the target is vague ("why do we do it this way?" with no clear referent), make your best guess from conversation context (open files, recent edits, cursor location, what was just discussed). State your interpretation briefly so the user can redirect if you're off, then proceed.
 
 ## Step 2. Establish the Code Anchor
 
-Before spawning investigators, anchor the investigation in concrete code. You need:
+Before spawning investigators, build the seed context inline: file paths and line ranges, key symbols (functions, classes, constants), the last few commits touching the target, PR numbers from merge commits (pattern `(#1234)` in the subject line), and any linked ticket IDs. Run `git blame -L <start>,<end> <file>` for last-touch commits, `git log --follow -p -- <file>` for full history with patches through renames, `git log --oneline -20 -- <file>` for recent commits with PR numbers visible, and `git log -1 --format=%B <commit>` to extract PR numbers. Then pull the PR bodies and discussion for any substantive commit: `gh pr view <number> --json title,body,author,createdAt,mergedAt,labels,closingIssuesReferences,comments,reviews`. This anchor goes to every investigator and to the synthesizer.

 ## When Evidence Contradicts
 
-If two sources disagree (the PR description says one thing, the ticket says another), surface both. Don't pick the one that fits a tidier narrative. A typical pattern:
-
-- **The ticket says** "we need this for customer X's compliance requirement"
-- **The PR says** "cleaning up tech debt in this area"

 ## When Evidence Is Missing
 
-An honest "we don't know" is one of the most valuable outputs this skill can produce. The user now knows:
-
-- The answer isn't in the obvious places
-- They'll need to ask a human (the original author, the product owner, the team lead) to find out
-- Or they can decide the question isn't worth pursuing further
-
-Failing to mark a gap and filling it with a confident guess actively harms the user. They'll act on the guess.

-When you hit a gap, name it concretely:
-- What question you were trying to answer
-- What sources you searched
-- What you searched for in each
-- What you found (nothing, or only tangentially related material)

+## Before Finalizing
 
-1. Does this claim have a citation? If not, either add one or move it to "Inferred" / "Hypotheses".

-3. Am I treating the code itself as evidence for its own intent? If so, that's not evidence. Remove or reclassify.

-- **Consider the counterfactual.** Before reporting a finding as strong, ask whether you would expect to find it if your current reading were wrong, and how the evidence would differ.

-- **Datadog**: `search_datadog_incidents` for formal incident records with timelines, dashboards and monitors created as postmortem action items
-- **Sentry**: issues whose first-seen/last-seen window aligns with the target's PR ship date, stack traces through the target
-- **Databricks**: product-analytics events that classify an error condition (client-reported failures, user-visible retry events, etc.) often spike during an incident window. A drop in that event count after the target PR ships is circumstantial support that the target code resolved the user-visible symptom, even when Datadog/Sentry signal is noisy.
-
-If you find an incident link, fetch the full postmortem. Postmortems typically have an "Action Items" section that ties directly to code changes. When multiple sources corroborate (a Datadog incident ID appears in a Linear ticket, which appears in a Notion postmortem, which appears in a Slack thread that links to the target PR, and the Databricks error-event count drops after the fix), the evidence is especially strong.
-
-Worth spending time on when the code's defensive character makes an incident-driven origin plausible. Skip it for code that doesn't look defensive.

 # Sentry Error History
 
-## What this source contains
-
-Sentry is the archive of things that went wrong. For defensive, corrective, or error-handling code, it often holds the direct motivation: the specific exceptions, stack traces, and frequencies that pushed someone to add a check, catch, retry, or fallback.
-
-- **Issues.** Grouped errors with counts, first/last seen timestamps, affected releases, and comments
-- **Events.** Individual error instances within an issue (stack traces, tags, user context)
-- **Releases.** Deployment records with associated issues (useful for "which version fixed this?")
-- **Replays.** Session recordings of user-facing errors (if enabled)
-- **Profiles.** Performance profiling data (less useful for "why", more for "how slow")
-- **Issue comments & assignments.** Sometimes contain engineer notes on root cause
-
-The most valuable thing Sentry provides is **temporal correlation**: "issue X was created 2024-01-02, peaked at 500 events/day, stopped appearing after release v2.14.0 on 2024-01-15, the release that shipped the defensive check."

-- An issue whose **first seen** is shortly before the target's PR and **last seen** shortly after, suggesting the target addressed this error

-- An issue with high event counts that stops after the release containing the target
-
-## Common pitfalls
-
-- **Grouping drift.** Sentry groups errors by fingerprint. Refactors or renames can track the "same" error under a new issue ID. If an issue ends abruptly, the error may have just been regrouped. Check for new issues immediately after.
-- **Release correlation is noisy.** A release contains many commits. An issue stopping at v2.14.0 doesn't prove the target fixed it. Another change in the same release might have. Cross-reference with the target's exact commit.
-- **Silent fixes.** Sometimes the error stops because upstream changed, not because of the defensive code. The correlation suggests the fix. It doesn't prove authorship.
-- **Resolved != fixed.** Issues can be marked "resolved" manually without any code change. Treat `resolved` as a human marker, not evidence that code fixed it.
-- **Seer hallucinations.** Seer can generate confident-sounding explanations that aren't right. Fall back to the actual events, stack traces, and timestamps when making claims.
-- **Sampling.** Some projects sample events aggressively. A low event count may just mean high sampling, not a rare error. If in doubt, note the gap.

-## What this source contains
-
-- Real-time discussions of problems and decisions
-- Incident channels where fire-drill decisions were made

-Slack is frequently where the *real* decisions got made, especially for smaller changes that didn't warrant a doc. It's also the most ephemeral source. Threads get deleted, channels get archived, and search quality degrades over time.

 Slack MCP tools vary. Check which Slack MCP is available and inspect its tool schema first. It may require `mcp_auth`. If authentication fails, stop and report the gap.
 
 1. **Author-bounded search.** Messages from the PR author around the PR merge date. Limits scope dramatically and often hits gold.
-2. **Keyword search for the feature name and key symbols.** Include misspellings and casual phrasings.
 3. **PR URL search.** Slack often links PRs when they're reviewed or discussed. Search for the PR URL (or just `/pull/<number>`).
 4. **Error string search.** If the code handles a specific error, search for the error string. Incident threads often surface.
-5. **Channel-scoped search.** Narrow to likely channels:
-   - `#eng-*`. Engineering discussions
-   - `#proj-*`. Project channels
-   - `#incident-*` / `#sev-*`. Incident channels

It matters when the user is new, the question is about setup or cost, or the answer depends on which models run. Ask at most once per session. If the need is also unclear, ask both questions together. Offer two choices:
+ 
+-- Now: give them `/setup-pstack` to type, and answer their question too.
+-- Later: answer their question, and add one line saying every role keeps its default model until they run `/setup-pstack`.
++- Now: give them `$setup-pstack` to type, and answer their question too.
++- Later: answer their question, and add one line saying every role keeps its default model until they run `$setup-pstack`.
+ 
+ ## Get set up
+ 
+-1. Install with `/add-plugin pstack` in chat, or from Customize in the sidebar.
+-2. Run [`/setup-pstack`](../setup-pstack/SKILL.md). It asks for a reasoning budget, maps a model to each role, and writes a rule. The rule applies to new chats. Then it offers once each to generate a verification skill and a formal verification skill for the project, unless the project already has one.
+-3. Start a real task with `/poteto-mode`, a goal, and a check that can pass or fail.
++1. Install the Codex build of pstack. There is no `/add-plugin` or Customize sidebar in Codex. Clone `https://github.com/foxytanuki/pstack-opencodex`, run `python3 tools/pstack_opencodex.py build`, then `python3 tools/pstack_opencodex.py install --target ~/.agents/skills` for every project, or `--target <project>/.agents/skills` for one project. If the user already keeps pstack skills in another skills folder, such as `~/.codex/skills`, keep that folder as the target instead of guessing a path. The installer symlinks into the checkout's `dist/skills/`, so keep the checkout in place. Start a new Codex session afterward. Codex must run through opencodex with a model catalog.
++2. Run [`$setup-pstack`](../setup-pstack/SKILL.md). It asks for a reasoning budget, maps a model from the catalog to each role, and writes `~/.codex/pstack-models.md`. The settings apply to new sessions. `python3 tools/pstack_opencodex.py check-models` validates the file, and `check-runtime --parent-model <model>` is the read-only preflight before delegating to a routed child such as Claude or Grok. Then it offers once each to generate a verification skill and a formal verification skill for the project, unless the project already has one.
++3. Start a real task with `$poteto-mode`, a goal, and a check that can pass or fail.
+ 
+-Installing changes nothing until the user invokes a skill. Only `/setup-pstack` loads from the user's words. The [README](../../README.md) and [guide page 1](../../docs/guide/01-setup.md) have the details. Offer to word their first prompt with them, per [`references/prompting.md`](references/prompting.md).
++Installing changes nothing until the user invokes a skill. Only `$setup-pstack` loads from the user's words; every other pstack skill runs only when the user invokes it or a playbook step runs it. The upstream [README](../../README.md) and [guide page 1](../../docs/guide/01-setup.md) describe the Cursor install, so use them for the concepts and the install steps above for the commands. Offer to word their first prompt with them, per [`references/prompting.md`](references/prompting.md).
+ 
+-If cost is the worry, say where the tokens go and how to spend fewer. pstack spends extra tokens on subagents and review panels. Rerun `/setup-pstack` and pick a smaller budget or cheaper models. A role set to `auto` or `inherit-parent` runs on the chat's model, which saves tokens when the chat runs on Auto or a cheaper model. A shorter panel list runs fewer subagents, one for each entry. Save `/poteto-mode` for work that needs rigor.

Save `$poteto-mode` for work that needs rigor.
+ 
+-pstack is built for Cursor, and it also installs in Claude Code with `/plugin marketplace add cursor/plugins`, then `/plugin install pstack@cursor-plugins`. There, each command takes a `pstack:` prefix, such as `/pstack:poteto-mode`. The [Claude Code adapter](../../docs/harness/claude-code.md) maps the Cursor names, and a step that needs a Cursor-only feature, such as Bugbot or Automations, is skipped with a one-line note.
++pstack was written for Cursor, and this build adapts it to Codex through opencodex. `HARNESS.md` maps Cursor tools, paths, and model names: `Task` becomes Codex's `spawn_agent`, and per-role models come from `~/.codex/pstack-models.md`. Routed children such as Claude need a compatible session. If delegation fails, run `check-runtime` and read its status instead of retrying. Cursor-only features, such as Custom Modes, cloud agents, and automations, are not available.
+ 
+-Other tools can read the skills, because they use the Agent Skills format. But most workflow skills, including `/poteto-mode`, `/how`, `/why`, and `/teach`, spawn Cursor subagents with per-role models, and Custom Modes and `/loop` are Cursor features, so those parts may not work there.
++Upstream pstack also installs in Claude Code through its own adapter. Those install steps and the `pstack:` command prefix do not apply to this Codex build.
+ 
+ ## Start a task with `/poteto-mode`
+ 
+ `/poteto-mode` matches the task to a playbook, copies the playbook's steps into the todo list, and runs the other skills as the steps need them. A step it skips stays in the list as `skip: <reason>`. A good prompt states the goal and how to tell it's done. It doesn't list skills, because a hand-written sequence tends to drop or reorder steps the playbook would keep. Read [`references/prompting.md`](references/prompting.md) before you help word one. [Guide page 2](../../docs/guide/02-poteto-mode.md) has examples.
+ 
+-Whether `/poteto-mode` stays on depends on how the user starts it:
++Codex has no Custom Modes and no Option+Enter shortcut. Whether `$poteto-mode` stays on depends on what the user says:
+ 
+-- Enter on `/poteto-mode` attaches the skill to one message. It fades as the chat moves on.
+-- Option+Enter on Mac or Alt+Enter on Windows, or Use as Mode from the skill entry, makes it a Custom Mode. It stays in context every turn until the user exits the mode, and it stays out of casual turns.
+-- Cursor's docs list Custom Modes in the Agents Window and the CLI. Elsewhere, start each new task with `/poteto-mode`.
++- Invoking `$poteto-mode` applies the skill to that task. It fades as the conversation moves on, so invoke it again for the next task.
++- A follow-up in the same session continues the same task. Say "new task" to make it match a fresh playbook.
++- A new Codex session starts with no memory of the last one. To continue a task, invoke `$poteto-mode` and say what to resume, or use the Session pickup playbook, which reads the branch, the worktree, and Codex's rollout files under `~/.codex/sessions/`.
++- Subagents run on this machine and stop when Codex exits. After a restart, treat them as gone and resume from their worktrees, branches, and ledger files.
+ 
+-Link [Cursor's skills docs](https://cursor.com/docs/skills) when this comes up. Mid-chat, "new task" makes the mode match a fresh playbook. `/poteto-mode` already uses `poteto-agent` for the subagents its playbook steps spawn. To get the same style from a subagent of your own, spawn it with `subagent_type: "poteto-agent"`.
++`$poteto-mode` already uses `poteto-agent` for the subagents its playbook steps spawn. To get the same style from a subagent of your own, follow `HARNESS.md`: start its message with an instruction to read `poteto-mode/SKILL.md` in full.

 - Subagent definitions: `{{PSTACK_DIST}}/agents/poteto-agent.md` and `{{PSTACK_DIST}}/agents/comment-sicko.md`.
 - Skill folders: `.agents/skills/` in the repository for project skills such as a generated `verify-<app>`, and `~/.agents/skills/` for user skills.
 - Cursor paths in pstack text map as follows. `.cursor/skills/` is `.agents/skills/`. `~/.cursor/skills/` is `~/.agents/skills/`, and Codex also reads `~/.codex/skills/`. `~/.cursor/plugins/` is `~/.codex/plugins/`. Project rules under `.cursor/rules/` are the repository's `AGENTS.md` files. `~/.cursor/projects/<slug>/agent-transcripts/` is covered under Transcripts. For worktrees under `.cursor/worktrees/`, use `git worktree list`, which finds worktrees wherever they live.
+- This build is not installed as a plugin. Where pstack text searches `~/.cursor/plugins/` for a pstack file, or picks the copy whose `.cursor-plugin/plugin.json` has the highest `version`, read the file under `{{PSTACK_DIST}}` instead.
+- `{{PSTACK_DIST}}/README.md` and `{{PSTACK_DIST}}/docs/` are unmodified copies of upstream's README and docs, so they describe Cursor. `{{PSTACK_DIST}}/docs/harness/claude-code.md` is upstream's Claude Code adapter. It does not apply to Codex; this file takes its place.
 
 ## Subagents
 
 - `Task` means Codex's `spawn_agent`. Use the collaboration tools actually exposed by the session. In the desktop surface, `wait_agent` waits for mailbox updates; read the delivered messages and final answers to collect results. `send_message` sends a message without starting an idle agent, `followup_task` assigns more work and starts an idle agent, and `interrupt_agent` stops its current turn while keeping it available. Interruption is not closure. Use `send_input`, `wait`, or `close_agent` only on hosts that expose those tools; do not invent absent tools.
 - Pass the prompt as `message`, and set `model` and `reasoning_effort` as described under Models. Drop `subagent_type`, `run_in_background`, and any other parameter Codex does not have. Codex subagents already run in the background.
+- Where pstack says to pick each subagent's reasoning level and fast or standard speed for the job, per the Subagents section of **poteto-mode**, adjust only `reasoning_effort`. Start from the role's value, move the effort the way poteto-mode says, then clamp it as described under Models. Codex has no per-spawn speed choice, so ignore the speed half and never add `-fast`. If the spawn rejects the adjusted effort, spawn with the role's value and say so.
 - When this host only accepts model overrides with a partial or empty fork, use `fork_turns: "none"` for independent tasks and include their context explicitly. This controls history inheritance, not V1/V2 transport or encryption.
 - `readonly: true` means the prompt must say the agent may read files and run commands but must not edit files, commit, or push.
 - `environment: "cloud"` means a local subagent that works in its own git worktree and output directory.
 - `subagent_type: "poteto-agent"` means a subagent whose message starts with "Read {{PSTACK_DIST}}/skills/poteto-mode/SKILL.md in full, including its Principles section, before any work." Then give the task.
-- `subagent_type: "Comment Sicko"` means a read-only subagent whose message starts with "Read {{PSTACK_DIST}}/agents/comment-sicko.md and follow it as your instructions."

 - A pstack step that tells you to spawn subagents is the skill instruction that authorizes spawning. A model chosen in the pstack settings file is the user's explicit model choice.
 - Codex can stop a subagent from spawning its own subagents (`agents.max_depth`). When a spawn fails for that reason, do those roles yourself, one after another, and say so in the report.

 - `/loop` means a timed wait between checks: a shell `sleep` of at most 60 seconds per call, repeated. In the Codex desktop app, a thread heartbeat automation can wake the thread for longer intervals.
 
+## Skill notes
+
+Invoke every skill as `$name`. These skills need more than the mappings above:
+
+- `ketchup`: the user's last message is the last one they typed in this session. `wait_agent` results, subagent messages, and notifications are not their messages. Give each screenshot or video the work produced as a Markdown image or link to its absolute local path, and say in the same line what it shows, since not every Codex client renders media inline. Write diagrams as fenced `mermaid` blocks. For charts, see `/visualize` under Tools pstack does not ship.
+- `poteto-help`: the build rewrites its install, settings, and mode guidance for Codex (overlay patch `0002`). Its links to the README and guide pages open the unmodified upstream copies, which describe Cursor's install, Custom Modes, and settings. For this build, install with `tools/pstack_opencodex.py build` and `install`, invoke skills as `$name`, start each task with `$poteto-mode` because Codex has no Custom Modes, resume a task in a new session through the Session pickup playbook, keep model settings in `~/.codex/pstack-models.md`, and say that `make-bot-ui` is not installed.
+- `create-formal-verification-skill`, `maintain-formal-verification-skill`, and `create-verification-skill`: write a generated project-local skill to the repository's `.agents/skills/<name>/SKILL.md`, with frontmatter whose `name` equals the folder name and a `description`. A session that started before the file existed may not list it, so open it by path or start a new session.
+- `correct`: the agent instruction file is the repository's `AGENTS.md`. Keep the rule table there.
+- `benchmark-checklist`, `principle-explain-the-number`, `in-your-own-words`, and `sharpen` need nothing beyond this file.
+
+## Help and guide pages
+
+`$poteto-help` links to `{{PSTACK_DIST}}/README.md` and `{{PSTACK_DIST}}/docs/guide/`. The build copies them unmodified from upstream, so they describe Cursor's install, Custom Modes, and settings. For this build, install with `tools/pstack_opencodex.py build` and `install`, and run skills as `$name`. Codex has no Custom Modes, so start each task with `$poteto-mode`; a new session does not remember the last one, so resume through the Session pickup playbook. Settings live in `~/.codex/pstack-models.md`, and `make-bot-ui` is not installed.
+
 ## Cursor features Codex does not have
 
 - Cursor cloud agents and the Cursor dashboard. Codex subagents run on this machine and stop when Codex exits. Their state lives in `wait_agent` results, their worktrees, pushed branches, and the program's ledger files. Where pstack describes a Cursor restart, apply the same rule to a Codex restart: treat every subagent as gone and resume from those records. Where pstack offers a local root or a cloud root, follow the local root instructions.
 - Cursor's built-in skills, such as its babysit skill. Codex has none of them, so follow the pstack playbook pstack names.
 - Cursor automations, webhook routines, and Grok Bots. The `make-bot-ui` skill depends on them and is not installed.
-- Graphite. Orchestrate's stack tools (`orch frontier`) run `gt` and read PR numbers through Graphite, which needs `gt auth` and `gt init` in the repository. Before starting Orchestrate, check `command -v gt` and check that `~/.config/graphite/user_config` contains an `authToken` key without printing its value, for example with `rg -q authToken ~/.config/graphite/user_config`. If `gt` is missing or not authenticated, tell the user before any work. The other playbooks use `gh` and never require `gt`.

 - `control-cli`: a tmux session or a PTY command for CLIs and TUIs.
 - Bugbot and Cursor's agentic security review: apply their triage rules to whatever review bots the repository uses. If none comment, skip those steps.
 - MCP discovery in the **why** skill: Cursor's `mcps/` directory means the MCP tools in your own tool list, named `mcp__<server>__<tool>`. `codex mcp list` shows the configured servers.
+- `/visualize`: Cursor's chart tool. Draw a fenced `mermaid` chart instead, such as `xychart-beta` for numbers, or give the numbers in one sentence. Never invent a number.
