Approve PR + Add to Merge Queue

Usage

/approve-pr              # approve current branch's PR
/approve-pr 123          # approve PR #123
/approve-pr feat/my-feat # approve PR for branch feat/my-feat

Workflow

Step 1 — Identify the PR

If a PR number is provided, use it directly.

If a branch name is provided:

gh pr list --head "{branch}" --state open --json number,title,url,headRefName --limit 1

If no argument is provided, detect from the current branch:

BRANCH=$(git branch --show-current)
gh pr list --head "$BRANCH" --state open --json number,title,url,headRefName --limit 1

If no open PR is found, inform the user and stop.

Step 2 — Approve the PR

gh pr review {number} --approve --body "LGTM"

If this fails (e.g. you are the PR author and cannot self-approve), inform the user and stop — do not proceed to merge queue.

Step 3 — Add to Merge Queue

First, fetch the PR's GraphQL node ID:

gh api repos/{owner}/{repo}/pulls/{number} --jq '.node_id'

Then add to the merge queue via GraphQL:

gh api graphql -f query='
  mutation($prId: ID!) {
    addPullRequestToMergeQueue(input: { pullRequestId: $prId }) {
      mergeQueue {
        id
        nextEntryEstimatedTimeToMerge
      }
    }
  }
' -f prId="{node_id}"

If the merge queue mutation fails (e.g. merge queue not enabled on the repo, or branch protection not satisfied), fall back to enabling auto-merge instead:

gh api graphql -f query='
  mutation($prId: ID!) {
    enablePullRequestAutoMerge(input: { pullRequestId: $prId, mergeMethod: SQUASH }) {
      pullRequest { autoMergeRequest { mergeMethod } }
    }
  }
' -f prId="{node_id}"

Report which path was taken and whether it succeeded.

Step 4 — Report

## Approved + Queued — PR #{N}: {title}

- Approved: ✅
- Merge queue: ✅ added  (or ⚠️ fell back to auto-merge, or ❌ failed — reason)
- URL: {pr_url}

Rules

• Never use gh pr merge — use the GraphQL API for merge queue / auto-merge
• Do not approve if already approved (check review state first with gh pr reviews)
• Do not approve your own PRs — stop and inform the user
• Always report the final state clearly
