marxbiotech PR Cache Cleanup
Remove cache files for PRs that have been merged or closed.
When to Use
Invoke this skill when:
- User wants to clean up stale cache files
- User says "clean up cache", "cleanup merged PR caches", "remove old caches", or "clear review cache"
- User wants to free up space from old cache files
Note: This skill has disable-model-invocation: true because it deletes files and should only be user-triggered.
Workflow
Step 1: Preview (Dry Run)
Always start with a dry run to show what would be deleted:
${CLAUDE_PLUGIN_ROOT}/scripts/cache-cleanup.sh --dry-run
Step 2: Confirm with User
Present the preview results to the user:
- How many files would be deleted
- Which PRs they belong to
- PR states (MERGED, CLOSED, NOT_FOUND)
Ask for confirmation before proceeding.
Step 3: Execute Cleanup
Only after user confirmation:
${CLAUDE_PLUGIN_ROOT}/scripts/cache-cleanup.sh
Step 4: Report Results
Inform the user:
- Number of files deleted
- Number of files kept (open PRs)
- Any errors encountered
Options
| Flag | Description |
|---|---|
--dry-run |
Preview only, don't delete |
--all |
Remove ALL cache files including open PRs (use with caution) |
