marxbiotech PR Cache Sync
Synchronize local cache with the latest PR review comment from GitHub.
When to Use
Invoke this skill when:
- User wants to ensure their local cache is up-to-date
- User suspects the cache might be stale
- User says "sync PR cache", "pull latest review", "refresh cache", or "update local cache"
Workflow
Step 1: Get PR Number (Cache-Aware)
PR_NUMBER=$("${CLAUDE_PLUGIN_ROOT}/scripts/get-pr-number.sh")
This uses the branch-to-PR-number cache (branch-map.json) with 1-hour TTL, falling back to GitHub API on cache miss.
If no PR exists for the current branch, inform the user and stop.
Step 2: Run Sync Script
${CLAUDE_PLUGIN_ROOT}/scripts/cache-sync.sh "$PR_NUMBER"
The script will:
- Show previous cache timestamp (if exists)
- Force refresh from GitHub
- Compare hashes to detect changes
- Report results
Step 3: Report Results
Inform the user:
- Whether the cache was updated
- If content changed since last cache
- The new cache timestamp
