# Merge PR

Merge the requested PRs immediately when possible, or enable auto-merge, and verify each result.

## Authorization

An explicit user invocation of `$merge-pr` is a merge request and authorizes merging the targets identified by the user's request or conversation context. This authorization includes enabling auto-merge for those targets when immediate merging is unavailable. The authorized targets include PRs returned by a selection workflow requested in the same message. Do not request confirmation again because the targets came from tool results rather than manually supplied PR numbers.

Automatic skill selection alone does not authorize merging or enabling auto-merge. A request to edit, inspect, or discuss this skill authorizes that work only. A handoff must retain the original human merge authorization and target scope.

## Core Rules

- Always use `gh pr merge` with `--squash`. Do not substitute merge commits or rebase merges.
- Never specify `--subject` or its short form `-t`, including an empty value. Leave the commit subject to the default `gh` and GitHub behavior. Do not override it interactively or through another merge interface.

See the [GitHub CLI merge documentation](https://cli.github.com/manual/gh_pr_merge) for these options.

## Resolve and Merge

Use the requested PR URLs, numbers, or selection criteria with the repository context. Resolve targets from the request and conversation context, including the complete results of a requested selection workflow. Use those targets even when the checkout has a detached HEAD.

Only when the request and conversation context do not identify targets, resolve the current branch's PR with `gh pr view --json url`. Ask for a target only when neither source identifies the intended PRs or when the requested scope is genuinely ambiguous. Do not ask for merge authorization again after an explicit invocation.

For an explicitly authorized workflow handoff with merge gates, honor its narrower constraints: let the caller own readiness checks, use its verified head with `--match-head-commit`, omit `--auto` when forbidden, and return after the single requested layer. A dependent stack stops on failure or a queued/unverified result instead of advancing to an upper PR. These constraints do not change the default direct-invocation behavior below.

Once the target is identified for a direct invocation, attempt the merge immediately. Do not preflight authentication, CI, reviews, draft status, conflicts, squash support, merge queues, or head SHAs. Let GitHub enforce its merge requirements. Do not announce plans to check readiness.

```sh
gh pr merge <PR_URL> --squash --auto
```

An explicit PR number can replace `<PR_URL>`. Use `--auto` by default unless the authorized handoff forbids it: `gh` merges immediately when possible and enables auto-merge when requirements remain unmet. Omit `--admin` and `--delete-branch` by default. Do not fix source, change PR metadata, submit approvals, or bypass rules to make the merge succeed. Additional actions require applicable human instructions. The two core rules still apply.

For multiple directly requested PRs without dependent-stack handoff constraints, attempt them sequentially in the requested order, or the supplied list order when no separate order is specified. Continue to the remaining PRs after an individual failure.

## Verify and Report

After each attempt, fetch the PR's URL, state, `mergedAt`, `mergeCommit`, and `autoMergeRequest`:

```sh
gh pr view <PR_URL> --json url,state,mergedAt,mergeCommit,autoMergeRequest
```

Report a completed merge only when GitHub confirms the PR is merged, and return its URL and merge commit SHA. Report an unavailable commit SHA or unreadable state as unverified.

For an open PR, report it as queued and pending if the CLI explicitly confirms merge queue registration. Otherwise, report auto-merge as enabled and pending when `autoMergeRequest` is non-null. Neither result is a completed merge. If verification cannot confirm the result, report it as unverified. Do not block the attempt because a queue applies or add `--admin` to bypass it.

If the command fails, including when auto-merge is disabled or permissions are insufficient, report the GitHub or CLI error briefly along with any verified outcome. Do not retry automatically or start a merge-readiness investigation. Keep the final report concise.
