# Git Branch Cleanup ## Host dispatch contract - Codex: `$skill`, Codex collaboration roles, and GPT-5.6 tiers. - Claude: `/skill`, Agent/Skill tools, and Claude aliases. - A bare `/skill` in this shared source denotes the Claude form; Codex dispatches the same named skill as `$skill`. Reconcile local branches with the base branch. Most "unmerged" branches are already squash-merged — this is mostly pruning, not merging. **Triage first, act second.** Never blind-merge: open PRs are operator-gated and CI can be red even when conflict-free. Pairs with `/git-branch-consolidate`, which audits the whole estate for spec/plan/test completeness and hands its `delete-safe` set here. This skill owns the deletion approval flow; consolidate owns the audit. ## Golden rules - **Assess before acting.** PR state is authoritative, not `git branch --merged` (misses squash-merges). - **Conflict-free != ready.** A clean merge-tree probe says nothing about CI. Check both. - **Open PR = operator decision.** Never auto-merge an open PR without explicit go. High-blast-radius changes (infra, multi-tenant, auth, row-level security, scheduled jobs) go through `/review-gate` first. - **Worktree before branch.** A branch with a worktree cannot be deleted; remove the worktree first. - **Never touch:** the base branch (`main`/`master`/`develop`), the current checkout, or any branch whose worktree was committed to in the last hour (active work). - **Preserve dirty state.** Uncommitted work in
