From eff68f3af380bd986fffbaae219e400231aaf1b1 Mon Sep 17 00:00:00 2001 From: Nick Cipollina Date: Fri, 7 Aug 2026 09:34:30 -0400 Subject: [PATCH 1/7] feat(skills): add official Compono agent skill pack Adds skills/compono - an AI-coding-agent skill teaching Claude Code and other npx skills-compatible agents to write, modify, review, and troubleshoot Compono-based unit tests correctly, instead of relying on AutoFixture-shaped pretrained habits that don't apply to Compono's source-generated, deterministic design. Design captured in ADR-0035/PLAN-0035: one skill with package-conditional references/ (composition model, registrations/profiles/scopes, diagnostics, xunit-v3, nsubstitute, bogus, patterns-and-antipatterns), chosen over a router+sub-skills split after studying microsoft/aspire-skills as architectural reference - Compono represents one cohesive agent workflow today, not several distinct operational domains. Every API/example was swept against src/ (found and fixed one invented reference to a non-existent internal method along the way), and 18 eval scenarios (tagged activation/routing/behavioral-correctness) validate the skill via spot-checked live runs. Also documents the skill in docs/getting-started/ai-agent-skill.md and links it from README.md and Next Steps.

The first post-MVP work +item is developer tooling, not a runtime feature: an AI-coding-agent +"skill" that teaches an agent (Claude Code, and other `npx skills`- +compatible hosts) how to write, modify, review, and troubleshoot unit +tests that use Compono in a *consumer's* test project. + +This is necessary because Compono deliberately looks similar to, but +behaves differently from, AutoFixture — the library most agents already +"know" from pretraining. An agent working from general .NET knowledge +will reach for AutoFixture-shaped habits (`[Frozen]`, `ConfigureMembers`, +customization override, reflection fallback) that either don't exist in +Compono or actively conflict with its source-generated, deterministic +design. `docs/research/0001-autofixture-comparison.md` and +`docs/migrating-from-autofixture.md` already catalog this gap from real +migration evidence (Milestone 7); this ADR is about encoding that +hard-won knowledge into something an agent consults *before* writing +code, not just something a human reads. + +This repo already installs skills itself via `npx skills` (see +`skills-lock.json`, `.agents/skills/`, `.claude/skills/`) and follows the +`.agents/skills/engineering-workflow` design process for exactly this +kind of decision. + +## Decision Drivers + +- The skill must reflect Compono's actual shipped public API — no + invented APIs, no forward-looking/roadmap content presented as current. +- Triggering accuracy: activate for genuine Compono test-authoring work, + never hijack ordinary non-Compono .NET test work. +- Context efficiency: an agent shouldn't have to load NSubstitute-specific + or Bogus-specific guidance for a project that doesn't reference those + packages. +- Maintainability: adding a future integration package (a new test + framework, mocking library, Verify, etc.) shouldn't require restructuring + the whole skill. +- Installability: must work via `npx skills add /compono` and the + `skills/` subpath form, per the `npx skills`/skills.sh convention this + repo already uses for its own tooling. +- Guardrail strength: the skill's primary value is stopping AutoFixture- + habit mistakes before they're written, not documenting the happy path. + +## Considered Options + +1. **One skill** (`skills/compono/`) — single `SKILL.md` with detection, + routing, default workflow, and guardrails in the body; deep material in + `references/`, loaded conditionally by which packages are detected. +2. **Router + focused workflow skills** (mirroring + [microsoft/aspire-skills](https://github.com/microsoft/aspire-skills) + more literally) — a top-level `compono` router skill plus separate + skills for, e.g., authoring vs. diagnostics vs. configuration. +3. **Core + per-integration skills** — `compono` (core) plus + `compono-xunit`/`compono-nsubstitute`/`compono-bogus` as independent + skills, split along package boundaries. + +## Decision Outcome + +Chosen option: **1, one skill** (`skills/compono/`), with progressive +disclosure through `references/`. + +Compono is a single, coherent agent workflow — recognize the project uses +Compono → inspect the type/collaborators → decide whether/how to compose +→ act → validate — regardless of which optional packages +(`Compono.XunitV3`/`Compono.NSubstitute`/`Compono.Bogus`) are installed. +A task like "compose a theory with a shared NSubstitute double and a +Bogus-generated email" touches all three integration surfaces *in one +decision*, not three sequential workflows. Aspire's multi-skill split is +justified there because its sub-skills are genuinely different +*operational domains* with different tools and blast radius — scaffolding +(`aspire-init`), process lifecycle/CLI safety (`aspire-orchestration`), +cloud/CI (`aspire-deployment`), observability tooling +(`aspire-monitoring`). Compono has no such domain split: everything is +"write or fix C# test code against one composition API." Splitting it +would force either constant cross-skill handoff mid-task, or duplicated +core-composition explanation copy-pasted into every sub-skill. + +**Studied from [microsoft/aspire-skills](https://github.com/microsoft/aspire-skills) +and adopted, adapted to a single skill instead of six:** + +- The `description` frontmatter as the actual triggering/boundary + mechanism: a bold skill-type tag, `USE FOR:` (concrete signals/phrases), + `DO NOT USE FOR: (use X)` redirects, and — since there's no sibling to + hand off to — a `SCOPES TO:` note on which reference files apply given + detected packages, replacing Aspire's `INVOKES:` (which names sibling + skills we don't have). +- A **Detection table** (signal → how to detect → confidence) gating + which `references/` files are relevant, adapted from the router + skill's pattern but living in the one `SKILL.md` instead of a separate + router file. +- **Guardrails separated by severity**: hard "never do this" rules + (no reflection fallback, no `Activator.CreateInstance` workaround, no + silent AutoFixture substitution) get a top-of-file refusal section like + `aspireify`'s `.aspire/modules/` rule; softer per-topic guardrails live + in `references/patterns-and-antipatterns.md` with the reasoning, not + just the rule. +- **Evals with a `skill-invocation`-equivalent check** — positive + activation (genuine Compono test work), negative activation (ordinary + xUnit/NSubstitute/Bogus work with no Compono involvement), and + correct-behavior scenarios (right API chosen, registration precedence + respected, no invented APIs) — scaled down from Aspire's 167-stimulus, + CI-gated suite to a handful of scenarios proportionate to one skill. + +**Deliberately not adopted**: Aspire's self-deactivating one-time skill +pattern (`aspireify`'s SCAN→PROPOSE→EDIT→VALIDATE→DEACTIVATE) — Compono +has no one-time scaffolding phase distinct from ongoing authoring; adding +Compono to a project and writing a Compono test are the same kind of +"compose something" task, not two phases of one bigger job. + +**Reference file set** (subject to renaming/consolidation during +implementation — see the escape-hatch principle below; this is a starting +shape, not a frozen list): + +- `composition-model.md` — `Composer`, `Create()`/`CreateMany()`, + `[Composable]`, generated-plan discovery, determinism/seeding (folded in + rather than split out — seeding is inseparable from how a composition + path is derived, not a separate workflow) +- `registrations-profiles-and-scopes.md` — `Register()`, + `For().Use()`/`.Member()`, `ICompositionProfile`, `[Shared]`, + recursion detection +- `diagnostics.md` — the CMP0001–CMP0012 compile-time table, the runtime + `CompositionException`/tree-path/seed format, and the reproduce-a- + failure workflow +- `xunit-v3.md` — `[Compose]`/`[Compose]`/`[Shared]` in test + methods (only relevant if `Compono.XunitV3` is referenced) +- `nsubstitute.md` — `UseNSubstitute()`, substitutable-shape rules (only + relevant if `Compono.NSubstitute` is referenced) +- `bogus.md` — `UseBogus()`/`UseBogus()`, conventions/aliases (only + relevant if `Compono.Bogus` is referenced) +- `patterns-and-antipatterns.md` — the guardrail/anti-pattern catalog, + including the AutoFixture concept-mapping table (folded in here rather + than a separate migration file — the migration guidance *is* the + antipattern catalog, framed from the AutoFixture-habit direction) + +**Escape-hatch principle for future growth** (the actual reusable +decision this ADR records, per the user's explicit direction during +design review): start with one skill because Compono today represents a +single cohesive agent workflow.

Is there an existing `ICompositionProfile` + this codebase already uses? +3. **Decide** whether Compono is appropriate at all — see **When not to + use Compono** below — then which mechanism fits: + - An ordinary value, composed from scratch each time → let Compono + generate it, no configuration needed. + - A specific fixed value needed for an assertion → inline value + (`[Compose(42, "widget")]`) or a member rule + (`.For().Member(x => x.Y).Use(...)`), not a post-hoc mutation + after `Create()`. + - The *same instance* needs to be shared across the composed graph and + the test body → `[Shared]` (in `Compono.XunitV3`) — see + `references/registrations-profiles-and-scopes.md`. Don't reach for + `[Shared]` just to "make things consistent" or as a perceived + performance win; ordinary composition is already cheap. + - Interface/abstract-class/delegate needs a real test double → + `Compono.NSubstitute`'s `UseNSubstitute()`, not a hand-rolled stub, + if that package is referenced. + - A `string` member needs a realistic value (email, name, address) → + `Compono.Bogus`'s member-name conventions or `UseBogus(...)`, if + that package is referenced. Don't reach for Bogus everywhere — plain + generated values are fine when realism doesn't matter to the test. + - Cross-test/cross-project reusable setup → an `ICompositionProfile`, + not a copy-pasted builder lambda in every test. +4. **Check `[Composable]` necessity** — see + `references/composition-model.md`'s Discovery section. Most types need + nothing; only add it when the type has no local `Create()`/ + `CreateMany()` call site the generator can walk from (e.g. it's only + ever reached indirectly, or it lives in a referenced assembly you can't + annotate directly). Never add `[Composable]` speculatively across a + type hierarchy "just in case." +5. **Act** — write the composition call, registration, or profile change. + Prefer existing project conventions (an established profile, an + existing member-rule pattern) over introducing a new mechanism for the + same problem. +6. **Compile and run.** A compile-time failure is a `CMP0001`-`CMP0012` + diagnostic from `Compono.Generators` — look it up in + `references/diagnostics.md` before guessing a fix. A test-time failure + is a `CompositionException` — read its tree-shaped path and `Seed:` + line (also see `references/diagnostics.md`) to find exactly which + nested dependency failed, rather than guessing from the root type. + +## Guardrails + +These are hard rules, not preferences. Compono's whole design point is +*not* being a reflection-based fixture library — violating these +undermines the reason Compono exists in this project. + +- **Never introduce runtime reflection as a workaround.** No + `Activator.CreateInstance`, no constructor/property reflection, no + "just reflect over the type" fallback when composition fails. Compono + has no reflection fallback today — a composition failure means the + generator needs a supported shape, or a provider/registration needs to + be added. Reflection is excluded from the default architecture by + design (ADR-0001); it is not a valid escape hatch even for "just this + one test." +- **Never silently substitute AutoFixture** (or another fixture library) + because it's more familiar or because a Compono composition is + failing. If Compono genuinely can't do something a test needs, say so + explicitly and let the user decide — don't quietly reach for a + different library. +- **Never re-register or re-customize the same type to "fix" a build + error.** A second `Register()` for the same `T` (directly, via a + profile, or across two profiles) is a build-time conflict, not + last-write-wins like AutoFixture customizations. If a registration + conflicts, that's a signal to consolidate, not to add another one. +- **Never mark broad swathes of a production model `[Composable]` + "to be safe."** It's a narrow discovery-gap opt-in, not a general + "make this type composable" marker — see Detection above and + `references/composition-model.md`. +- **Never treat a `CompositionException` as flaky-test noise to retry.** + It's deterministic and reproducible from its own seed. Investigate and + fix, or use the seed to reproduce locally — don't wrap it in a retry. +- **Never hardcode "seed X produces value Y" as a permanent assertion.** + Determinism holds for a given Compono version, not across versions. + Only assert on values you explicitly pinned (inline values, member + rules, `[Shared]` reference equality). +- **Never bypass a `CMP0001`-`CMP0012` compile error by working around + the generator** (e.g. hand-writing a plan, suppressing the diagnostic, + or switching the type to be constructed manually elsewhere just to + dodge it).

From 7b6e05974640d9cb814c12e76fc861b394aa27b5 Mon Sep 17 00:00:00 2001 From: Nick Cipollina Date: Fri, 7 Aug 2026 10:58:33 -0400 Subject: [PATCH 5/7] test(skills): run the real skill-creator eval workflow, 97.4% vs 56.4% Closes the eval-workflow gap flagged in Jonas's PR #63 review. Ran the actual /skill-creator workflow instead of the earlier manual spot-check: 36 subagent runs (18 evals x with-skill/baseline), 18 independent grader subagents (one per eval, grading both variants against the same expectations), aggregated into benchmark.json/benchmark.md. Result: 97.4% pass rate with the skill (38/39 assertions) vs. 56.4% without it (22/39) - a real, evidence-backed gap. Summary artifacts and per-scenario grading committed at skills/compono/evals/benchmarks/, raw transcripts kept out of git per scope decision. Recorded honestly, not oversold: one run per configuration rather than skill-creator's default three, no timing/token capture, and a real methodology gap multiple graders independently caught - baseline subagents kept full repo filesystem access despite being told not to read the skill, so the true gap against a genuinely repo-isolated baseline is probably larger than 97.4/56.4, not smaller. Graders also surfaced concrete eval-quality feedback (several assertions pass regardless of skill use) - recorded as a follow-up in the benchmark README, not acted on in this pass. PLAN-0035 Status stays In Progress - the remaining Group 3 item (a real npx skills add run against a merge-ready ref) is still outstanding.

More significant here: without_skill produced fluent, specific Compono knowledge despite supposedly not having the skill loaded, which is a bigger issue for eval validity than the assertion wording — it suggests the with/without comparison may not be clean for this eval." + } +} From a8b81d2897d598315ec85c00dd02930f8dc8c396 Mon Sep 17 00:00:00 2001 From: Nick Cipollina Date: Fri, 7 Aug 2026 11:12:56 -0400 Subject: [PATCH 6/7] fix(skills): move evals/ out of the installable skill directory npx skills add does a recursive copyDirectory of a skill's whole folder (excluding only .git, per the real vercel-labs/skills source) - there's no ignore-file mechanism to exclude files. skills/compono/evals/ (the eval scenarios plus the 40-file benchmarks/2026-08-07/ report) would therefore have shipped into every consumer's install, with zero value to them. Moved to skills/compono-evals/ (sibling, no SKILL.md so npx skills never discovers it as an installable skill, outside skills/compono/'s own copy scope). Updated all path references in PLAN-0035 and recorded the defect in its Notes. Caught by the user reading the committed benchmark.md and asking whether it would ship - not caught by any review round before that.

Date: Fri, 7 Aug 2026 11:46:18 -0400 Subject: [PATCH 7/7] fix(skills): address Jonas's second PR #63 review round, run real npx skills add 6 confirmed findings: - diagnostics.md's troubleshooting step 6 had the same unscoped "deterministic, don't retry" claim already fixed in SKILL.md's guardrail during the first review round - missed the duplicate. Scoped identically (consumer factories/providers/IServiceProvider can be non-deterministic, inspect those first). - evals.json's eval 4 prompt never established Compono/Compono.XunitV3/ Compono.NSubstitute were installed or that it's a [Compose] row, yet its assertions required a [Shared] recommendation. Added the missing package/row context. - composition-model.md's seed rationale was still wrong in a subtler way than the first fix: re-verified Composer.cs directly - the fresh-random-seed behavior happens inside Create()/CreateMany() themselves (_configuration.Seed ?? CompositionSeed.Generate()), not at Composer.Create(...) construction time, so an unseeded composer draws a fresh seed on every individual call regardless of instance reuse. Rewrote precisely. - benchmarks/2026-08-07/README.md linked ../evals.json (resolves to a nonexistent path); fixed to ../../evals.json. - The eval-workflow completion claim was imprecise about what's actually retained - reworded so it's explicit that eval_metadata.json/per-run outputs only ever existed in ephemeral scratch, and timing.json/ metrics.json were never captured at all, not merely uncommitted. Also closed the one item both prior review rounds correctly left open: ran a real npx skills add (against the local checkout, since GitHub's URL parsing can't disambiguate a slash-containing branch name from a subpath) - confirmed it discovers exactly one skill (compono) and installs exactly SKILL.md + the 7 references/*.md files, nothing from compono-evals/.
