description	Re-detect this project's tech stack from package.json / requirements.txt / pyproject.toml / go.mod / Cargo.toml and diff it against the Tech Stack section of every CLAUDE.md. Read-only — returns added / removed / renamed dependencies, never edits.
when_to_use	Use when the user asks "is my Tech Stack section up to date?", "what deps changed?", "rescan my dependencies", after dependency upgrades, or as part of /sync-claude-md --weekly.

CLAUDE.md Dependency Rescan (forked, read-only)

Optional explicit manifest: $ARGUMENTS (default: auto-detect all five manifest types).

Run these steps in order. Do not modify any file.

1. Detect manifests. Look for package.json, requirements.txt, pyproject.toml, go.mod, Cargo.toml at the repo root and one level deep (workspaces/monorepos).
2. Extract declared dependencies from each:
   • package.json → keys of dependencies and devDependencies (skip versions).
   • requirements.txt → first token of each non-comment line.
   • pyproject.toml → [project.dependencies] / [tool.poetry.dependencies] keys.
   • go.mod → module paths under require (...).
   • Cargo.toml → keys under [dependencies] / [dev-dependencies].
3. Inventory documented deps in every CLAUDE.md (and .claude/rules/*.md): grep for the Tech Stack / Dependencies sections and the lists under them.
4. Compute three sets per file:
   • added: in manifest but absent from this CLAUDE.md.
   • removed: documented in this CLAUDE.md but absent from manifest.
   • renamed: documented and present in manifest but spelled differently (react-router vs react-router-dom, pg vs psycopg2).
5. Return in this exact shape:

## Dependency Rescan

Manifests detected: <list>
Total declared deps: <count>

### Per file
#### <path-to-CLAUDE.md>
- Added (in manifest, not documented): <list or "none">
- Removed (documented, not in manifest): <list or "none">
- Renamed / aliased: <list or "none">

6. If every documented set matches its manifest, return exactly ## Dependency Rescan\n\nAll documented deps match manifests. <M> files inspected.. Do not pad.

Hard rule: do not propose specific edits — just surface the diffs. /sync-claude-md decides whether to write them.
