CLAUDE.md Drift Audit (forked, read-only)

Days window: $ARGUMENTS (default 7 if empty).

Perform these steps in order, then return a single punch-list summary. Do not modify any file.

1. Inventory every CLAUDE.md and *.claude/rules/*.md in the tree using find . -name "CLAUDE.md" -type f -not -path "*/.git/*" -not -path "*/node_modules/*". List paths and line counts.
2. Collect change signal for the window:
   • git log --since="$ARGUMENTS days ago" --name-status --no-merges --diff-filter=DR → deleted and renamed paths.
   • git diff "@{$ARGUMENTS days ago}" --name-status -- package.json requirements.txt pyproject.toml go.mod Cargo.toml 2>/dev/null → manifest deltas (removed/added deps).
3. Cross-reference each CLAUDE.md against those signals using grep / Read:
   • Mark any line that names a deleted or renamed path.
   • Mark any line in a Tech Stack / Dependencies section that names a removed dep.
   • Mark any @path/... chain import or markdown link whose target was deleted.
4. Return the punch list in this exact shape (markdown), nothing else:

## Drift Audit (window: <N> days)

Total CLAUDE.md inspected: <count>
Signals examined: <deleted_paths>, <renamed_paths>, <removed_deps>

### Findings
- <path>:<line> — <one-sentence reason> — suggested action
- ... (one bullet per drift; omit section if empty)

### Clean
- <path> (lines unchanged, references valid)

5. If no drift is found, return exactly ## Drift Audit\n\nNo drift in <N>-day window. <count> files inspected.. Do not pad the output.
