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:

bash

${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:

bash

${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)
