-name: merge-green-prs
-description: Check this repo's open pull requests and merge the ones from claude/* branches whose tests have passed. Use when asked to merge green PRs, watch PRs, or clear the PR queue. Never merges a PR from any other branch.

-# Merge green PRs
-
-Repo: the current repository (`owner/repo` from the git remote). Use the GitHub MCP tools (`mcp__github__*`), never `gh`.
-
-## Which PRs are eligible
-A PR is merged only if ALL of these hold; otherwise report it and leave it alone:
-1. Open and not a draft.
-2. Head branch starts with `claude/` and lives in this same repo (not a fork).
-3. Base branch is the default branch.
-4. `mergeable_state` is `clean` (not `blocked`, `behind`, `dirty`, `unstable`, `draft`, `unknown`).
-5. Its check runs (`get_check_runs`) exist, are all `completed`, and every one has conclusion `success`.
-6. No review with `CHANGES_REQUESTED` (`get_reviews`) and no unresolved review thread (`get_review_comments`).
-
-## Steps
-1. `list_pull_requests` (state `open`). Skip, with the reason, everything that fails 1-3.
-2. For each remaining PR, read it fresh from GitHub: `pull_request_read` `get`, `get_check_runs`, `get_reviews`,
-   `get_review_comments`. Never rely on earlier results or memory for a PR's state.
-3. Checks still `queued` or `in_progress` -> "waiting", do nothing. Any failure -> "red", say which check, do not merge.
-   `behind` or conflicted -> report; do not update the branch or merge without being asked.
-4. Eligible -> `merge_pull_request` with `merge_method: merge` and `expectedHeadSha` set to the head SHA you just read
-   (so a push that lands in between aborts the merge).
-5. Read the PR back from GitHub and confirm `merged: true`. If the session was subscribed to it, unsubscribe.
-6. Finish with one table: PR number and title, outcome (merged / waiting / red / blocked / skipped), and the reason.
-
-## Never
-- Merge a PR from a branch that doesn't start with `claude/`, a fork, a draft, or one with a failing, missing or pending check.
-- Skip, disable or re-run tests to get green; push to a PR's branch; force-push; approve reviews; close PRs; delete branches.
-- State a PR's status without reading it from GitHub in this run.
