When to Use This Skill
| Use this skill when... | Use the alternative when... |
|---|---|
| Running git gc, repacking objects, or shrinking the .git directory | Use git-coworker-check first if other agents may be writing to the same checkout |
| Pruning merged local branches and old stashes | Use git-cli-agentic for read-only branch/stash queries without mutating state |
| Verifying repo integrity with git fsck | Use git-security-checks for secret scanning rather than object integrity |
| Cleaning up a checkout before a long-lived feature branch goes stale | Use git-rebase-patterns to clean up commit history rather than the object store |
Context
- Current branch: !
git branch --show-current - Git status: !
git status --porcelain=v2 --branch - Local branches: !
git branch -vv --format='%(refname:short) %(upstream:short) %(upstream:track)' - Stash list: !
git stash list - Repository size: !
du -sh .git
Parameters
Parse these parameters from the command (all optional):
--prune: Remove unreachable objects and optimize repository--gc: Run git garbage collection (aggressive)--verify: Verify integrity of git objects--branches: Clean up merged branches only--stash: Clean up stashes only--all: Run all maintenance tasks (default if no flags specified)
Your task
Perform repository maintenance and cleanup based on the flags provided.
Step 1: Check for accidentally committed files
- Environment files, IDE files, dependencies, build artifacts, secrets
- Suggest adding to
.gitignoreand removing withgit rm --cached
Step 2: Update .gitignore
- Suggest common patterns if missing
- Offer to append missing patterns
Step 3: Delete merged branches (if --branches or --all)
- List and clean branches merged via GitHub PR
- Protect main, master, develop, staging, production
- Delete local branches safely with
git branch -d - Require user confirmation before deleting branches
Step 4: Clean up redundant stashes (if --stash or --all)
- Show stash ages and context
- Suggest cleanup for old stashes (>30 days)
- Drop stashes from deleted branches
- Require user confirmation before dropping stashes
Step 5: Repository optimization (if --prune, --gc, or --all)
# Prune unreachable objects
git prune
# Run garbage collection
git gc --aggressive
# Repack objects
git repack -ad
# Show size improvement
du -sh .git
Step 6: Verify repository integrity (if --verify or --all)
git fsck --full --strict
Report any issues found.
Step 7: Final summary
- Report all actions taken
- Show before/after metrics
Safe Operations
These operations are safe and non-destructive:
git gc- Garbage collectiongit prune- Prune unreachable objectsgit fsck- Verify integrity
These require user confirmation:
git branch -d- Delete branchesgit stash drop- Drop stashes
