+# llm-sync: PluginSource doesn't scan marketplace-installed Claude Code plugins (Priority 3 | Status: in_progress)
+
+## Description
+## Problem
+
+`PluginSource` in [`stapler-scripts/llm-sync/src/sources/plugins.py`](stapler-scripts/llm-sync/src/sources/plugins.py#L28-L40) only scans two locations for plugins to sync to Antigravity/OpenCode:
+
+```python
+def _find_global(self) -> Optional[Path]:
+    candidates = [
+        Path.cwd() / "plugins",
+        Path.home() / ".config" / "llm-sync" / "plugins",
+    ]
+    ...
+
+def _find_local(self) -> Optional[Path]:
+    local = Path.cwd() / ".claude-plugins"
+    return local if local.exists() else None
+```
+
+Claude Code plugins installed via `/plugin install` from a marketplace live under `~/.claude/plugins/marketplaces//...//` (confirmed on this machine: `~/.claude/plugins/known_marketplaces.json` lists `claude-plugins-official`, with plugins actually installed under `~/.claude/plugins/cache/claude-plugins-official/...` per `~/.claude/plugins/installed_plugins.json`). None of these paths are scanned by `PluginSource`, so any skill/command/agent that ships as a real marketplace plugin (rather than as a loose file under `.claude/skills/`, `.claude/agents/`, `.claude/commands/`, which the separate `ClaudeSource` recursive glob does pick up) silently never reaches Antigravity or OpenCode.
+
+Note: this is distinct from — and narrower than — namespaced skills like `sdd:1-ideate`. Those are just nested directories under `.claude/skills/sdd/skills/` and already sync fine via `ClaudeSource.load_skills()`'s recursive glob. This issue is specifically about content packaged as an actual Claude Code *plugin* (with a `.claude-plugin/plugin.json` manifest) and installed through the marketplace mechanism rather than placed directly in `dotfiles/plugins/`.
+
+## Suggested fix
+
+Add `~/.claude/plugins/cache/*/*` (or read `~/.claude/plugins/installed_plugins.json` to resolve exact install paths) as an additional candidate root in `PluginSource._find_global()`, alongside the existing dotfiles-local and `~/.config/llm-sync/plugins` paths.
+
+## Evidence
+- `stapler-scripts/llm-sync/ [truncated]
+
+## Acceptance Criteria
+0. [ ] PluginSource discovers plugins installed via the Claude Code marketplace mechanism by resolving installPath entries from ~/.claude/plugins/installed_plugins.json, in addition to the existing ./plugins and ~/.config/llm-sync/plugins roots
+1. [ ] Plugins marked disabled (false) in ~/.claude/settings.json's enabledPlugins map are excluded from the sync output
+2. [ ] A missing or malformed ~/.claude/plugins/installed_plugins.json does not crash llm-sync; it results in zero marketplace plugins loaded plus a console warning, matching the existing error-handling style in PluginSource
+3. [ ] When the same plugin name exists both in a local/dotfiles root and via marketplace install, the local copy wins (existing local-overrides-global precedence is preserved)
+4. [ ] cli.py's sync_plugins actually installs/syncs discovered marketplace plugins to the Claude and Antigravity global targets, not just loads them into memory
+5. [ ] An installed_plugins.json entry with multiple scope records (list-valued) for the same plugin resolves to exactly one Plugin object, not duplicates
+6. [ ] A stale installPath (directory no longer present on disk) is skipped without aborting the rest of the marketplace scan
+7. [ ] Verified on the reference machine: kotlin-lsp@claude-plugins-official (currently disabled) is excluded from sync output; toggling enabledPlugins to true (or removing the key) causes it to be included

+## Notes
+Imported from https://github.com/tstapler/dotfiles/issues/36
+
+## Prior Attempts
+- Role: triage | Commits: 0
+--- END BACKLOG ITEM DATA ---
+
+Your plan is at `/home/tstapler/.stapler-squad/triage-artifacts/b608ab1e-b86e-4130-8879-7328cd363063/plan.md`. Read plan.md and validation.md before writing code.
+
+## Your Task Protocol
+1. Read ALL acceptance criteria before starting any work.
+2. Work through criteria systematically; run `/backlog/done-N` when criterion N is complete. If you
+need to manually run a standalone stapler-squad instance to click through a change by
+hand, see CLAUDE.md's "Manual/interactive testing without touching the live deployed
+instance" section - use a distinct PORT and STAPLER_SQUAD_INSTANCE every time, and kill
+that instance yourself once you are done with it. Never leave one running in the
+background. Other sessions in this same workspace will not know it exists, and repeated
+unclosed instances have previously exhausted this machine's memory.
+3. When ALL criteria are done, run `/backlog/review` with a 2–3 sentence summary of what you built.
+4. If you hit a blocker or need human input, run `/backlog/review` describing what you need — do not stop silently.
+5. If your context is compacted or you lose track of your task, re-read `.backlog-context.md` or run `/backlog/status` immediately before continuing.
+6. If the `/backlog/*` commands fail or the MCP server is unavailable, continue your work using the criteria listed in `.backlog-context.md` and record completed criteria in your commit messages.
+7. NEVER end your session without calling `/backlog/review` — this is how the task is closed properly.
+8. After `/backlog/review`, stay in this session — do not exit. Wait roughly 2-3 minutes, then run `/backlog/status` again to check for a verdict. PASS → immediately run `/backlog/ship` yourself to open the pull request (it drives `/github:pr-ship`, which can rebase, resolve merge conflicts, and react to failing CI checks) — shipping the PR is part of this task, not a separate step someone else does; do not stop here. FAIL/PARTIAL → fix the noted gaps yourself and run `/backlog/review` again.
+9. Keep count of how many times you've run `/backlog/review` in THIS session (count your own calls in this conversation — nothing tracks it for you). After 3 review cycles without a PASS, STOP looping: run `/backlog/ship` anyway to open a PR so a human can pick up the review directly, rather than retrying `/backlog/review` again. Nothing will kill or replace this session while you do any of this.
+
+## Fallback Instructions
+If MCP tools are unavailable, continue using the acceptance criteria above.
+Record completed criteria in commit messages. Run git commit after each criterion is done.
+
+## Before You Start
+This worktree's branch may be behind main (this file is rewritten on every spawn and re-attach, but the branch itself is not auto-synced). Run `git merge main` before starting substantive work. If it merges cleanly, continue. If it conflicts, resolve them as part of this task — you have the context to do it correctly; a background process does not.

+You are ready to ship your work as a pull request — either because /backlog/review just returned PASS, or because review has looped without reaching a PASS and it's time to hand the work to a human instead of retrying indefinitely.
+
+Before shipping, confirm all acceptance criteria are marked complete (`/backlog/status`).
+
+Steps:
+1. Create the pull request:
+   Run `/github:pr-ship` — this drives the PR through local CI, code review, remote CI, and
+   merge-conflict resolution. It will stop short of actually merging; the final merge is left to
+   the human reviewer.
+
+2. Once `/github:pr-ship` reports all gates green: if this work has NOT already received a PASS verdict (i.e. you're shipping because review looped without converging, not because it passed), request the automated review with the PR number included:
+   Run `/backlog/review` with a 2-3 sentence summary of what was built and the PR number.
+   If review already returned PASS before you got here, skip this — running it again will fail (the    item is no longer `in_progress`), and there's nothing left for it to check.
+
+3. Report the PR back onto this backlog item — REQUIRED, do not skip:
+   Call the report_pr_created MCP tool with item_id=b608ab1e-b86e-4130-8879-7328cd363063, pr_url=<the PR URL /github:pr-ship or gh pr create printed>, pr_number=<the PR number>, and summary=<2-3 sentences: what changed and why>.
+   You created this PR yourself — nothing else will ever report it back to the item record. Skipping this step leaves the item stuck in review with a real PR that is invisible to the reviewer and the operator.
+
+Note: if the repository has no GitHub remote, run `gh pr create` manually — do NOT use `--fill`, which
+just concatenates commit messages with no test plan. Write `--title` using Conventional Commits format
+and a `--body` structured as `## Summary` (why this change was made, from the backlog item above),
+`## What Changed` (a short bullet list), and `## Test plan` (a checklist of concrete verification steps).
+Then run `/backlog/review`, then step 3 above to report the PR.
