Cleanup Stale Branches

Delete local and remote git branches that no longer have an open PR, and prune stale worktrees.

Arguments

• --dry-run — List what would be deleted without actually deleting anything.

$ARGUMENTS

Procedure

Step 1: Checkout main branch

Switch to main and update to latest:

git checkout main
git pull --rebase origin main

Critical: This ensures we're not on a branch that's about to be deleted, and that we're working from the latest main.

Step 2: Fetch and prune remote refs

git fetch --prune origin

Step 3: Identify stale remote branches

List all remote branches except main and HEAD:

git branch -r --format='%(refname:short) %(committerdate:relative)' | grep -v 'origin/main\|origin/HEAD\|^origin '

Step 4: Get branches with open PRs (protected)

gh pr list --repo OpenRouterLabs/spawn --state open --json headRefName --jq '.[].headRefName'

Any branch with an open PR MUST be skipped. Never delete a branch that has an open PR.

Step 5: Delete stale remote branches

For each remote branch that is NOT in the open PR list:

git push origin --delete BRANCH_NAME

If --dry-run was passed, print [dry-run] would delete origin/BRANCH_NAME instead.

Step 6: Delete stale local branches

List local branches (excluding the current branch and main):

git branch --list | grep -v '^\*' | grep -v '^ *main$' | tr -d ' '

For each, check if it's already merged into main or has no remote:

git branch -d BRANCH_NAME 2>/dev/null || git branch -D BRANCH_NAME

If --dry-run, print [dry-run] would delete local BRANCH_NAME instead.

Step 7: Prune worktrees

git worktree prune

Remove any leftover worktree directories:

rm -rf /tmp/spawn-worktrees 2>/dev/null || true

Step 8: Verify final state

Ensure we're on main branch:

git branch --show-current

Should output: main

Step 9: Summary

Print a summary:

• Number of remote branches deleted
• Number of local branches deleted
• Number of branches skipped (had open PRs)
• Worktree prune status
