Merge Github Pr

Merge GitHub PR

Purpose

Merge pull requests that meet all required conditions.

---

Constraints

• Apply @rules/git/general.mdc
• Never merge a PR without a converged code review. A code review must have been run on the PR's final diff and report no errors — 0 Critical + 0 Moderate findings (Minor does not block). This is the hard merge gate from @rules/git/general.mdc Merging; it is mandatory on every merge and is verified in step 2 below.
• Never merge PRs with conflicts
• Never merge PRs with failing CI (unless explicitly instructed)
• Never bypass required approvals or protections
• The only tolerated CI failure is a GitHub Actions billing / account-limit error when the merge is explicitly requested (see GitHub Actions billing exception below). Any other failure — real test failure, lint, static analysis — still blocks.

---

Execution

1. Load PRs

• Identify candidate PRs ready for merge
• For each candidate, load PR context by running skills/code-review-github/scripts/load-issue.sh — the single deterministic entry point. Never call gh pr view, gh pr checks, or gh api /repos/.../pulls/... directly. Read isDraft, mergeable, mergeStateStatus, reviewDecision, and statusCheckRollup[] off the resulting JSON document.
• If the script is unavailable (missing tool, exit code 2/3) fall back to the GitHub MCP server.

2. Pre-checks (must all pass)

For each PR, derive the verdict from the JSON document loaded in step 1:

• Converged code review on the final diff (hard gate, no exception) — a code review must have run on the exact commits being merged and report no errors: 0 Critical + 0 Moderate findings (Minor does not block). Verify it from the PR's review comments in the loaded JSON: locate the latest code-review status comment (the technical CR comment / convergence status posted by @skills/code-review-github/SKILL.md / @skills/process-code-review/SKILL.md), confirm it reports criticalCount + moderateCount == 0, and confirm it reflects the head commit. Because the CR comment is upserted in place (@skills/code-review/SKILL.md Cross-run history — follow-up runs edit the same comment), use its updatedAt (not createdAt) for the staleness check: it is current only when updatedAt is at or after the newest commits[].authoredDate (the head commit). A comment whose updatedAt predates the head commit is stale and does not count. If no code-review comment exists, the latest one still carries Critical / Moderate findings, or its updatedAt predates the head commit, do not merge — report that the code-review gate is unmet and that the review must be run (or re-run) to convergence via @skills/code-review-github/SKILL.md + @skills/process-code-review/SKILL.md first. This gate is never waived — not by an explicit merge request, not by the billing exception below, and not by a GitHub reviewDecision == "APPROVED" on its own.
• Not a Draft — isDraft == false. A Draft PR signals the review/fix loop has not converged (@rules/git/general.mdc Draft pull requests): the Draft state mirrors the unmet code-review gate, so do not merge a Draft and report it as skipped. If the PR's code review has in fact converged (0 Critical + 0 Moderate), it must first be promoted out of Draft by @skills/process-code-review/SKILL.md (gh pr ready) before this skill will merge it — never flip a Draft to ready here just to merge it. The billing exception below never relaxes this.
• No merge conflicts — mergeable == "MERGEABLE" and mergeStateStatus is not DIRTY or BEHIND
• CI is passing — every entry in statusCheckRollup[] has a passing state (SUCCESS / NEUTRAL / SKIPPED), with the single billing exception below when the merge was explicitly requested
• Required approvals are present — reviewDecision == "APPROVED"
• Branch is up to date with base branch — mergeStateStatus != "BEHIND"

If any check fails:

• do not merge
• report reason

GitHub Actions billing exception (explicit merge only)

A single, narrow exception relaxes the CI-passing check — only when the caller explicitly requested the merge (an automatic / opportunistic merge never qualifies):

• When it applies: the only blocking entries in statusCheckRollup[] are GitHub Actions runs that did not execute because of a billing / account-limit problem — typically a state of ERROR (or a workflow that never started) whose detail message is an unambiguous billing notice such as "The job was not started because recent account payments have failed or your spending limit needs to be increased", "billing", or "spending limit". In that case the gate ignores those specific entries and allows the merge.
• Detection must stay conservative. Treat an entry as a billing failure only when its message clearly names a billing / payment / spending-limit cause. A bare ERROR / FAILURE with no billing wording is a real failure — never assume billing. When in doubt, do not merge: report the ambiguous entry and stop.
• The exception is billing-only. It never relaxes any other gate: a missing or non-converged code review (the hard CR gate above), a Draft PR (isDraft == true), a real CI failure (tests, lint, static analysis) on any non-billing entry, mergeStateStatus == "DIRTY" / "BEHIND", an unmergeable state, or reviewDecision != "APPROVED" still blocks the merge regardless of the explicit request.
• Report what was waived. When the merge proceeds under this exception, list each ignored billing entry (check name + the billing message) in the output so the waiver is auditable.

When the merge was not explicitly requested, this exception does not apply — a billing failure blocks like any other failing check.

3. Merge

• Merge PR using CLI
• Use project default merge strategy

4. Post-merge

• Delete branch (if configured)
• Remove worktree (opt-in only) — if an isolated git worktree was explicitly created for this work unit (per @rules/git/general.mdc Worktrees / Workspaces), remove it now that the merge is complete:

1. Verify the worktree is not the currently active working tree and has no uncommitted changes. If it is active or dirty, report the issue and skip removal — never pass --force.
2. git worktree remove — removes the worktree directory and its metadata.
3. git worktree prune — cleans up any remaining stale worktree metadata.

If no worktree was explicitly created for this work unit (the default: agent worked in the shared tree), skip this step entirely.

• Confirm merge success

Output

• List merged PRs
• List skipped PRs with reasons

---

Principles

• Safety over speed
• Never bypass CI or review gates — a converged code review (0 Critical + 0 Moderate) on the final diff is a mandatory precondition for every merge
• Merge only fully ready PRs
• Be explicit about skipped PRs
