Merge PR and Clean Up

Merge a pull request using a merge commit, then prune stale local branches.

Your Task

1. Identify the PR to merge:
   • If a PR number or URL is provided as an argument, use that.
   • Otherwise, detect the current branch and find its associated PR:

     gh pr view --json number,title,state,mergeStateStatus
     

   • If no PR is found, tell the user and stop.
2. Check PR is ready to merge:
   • Verify the PR state is OPEN.
   • Check mergeStateStatus — if it’s BLOCKED, BEHIND, or DIRTY, warn the user and stop.
3. Merge the PR:

   gh pr merge <number> --merge
   

   • Always use --merge (merge commit), never squash or rebase.

Important

• Always use merge commits (--merge), per project git preferences.
• If the merge fails, show the error and do not proceed to cleanup.
