Review External PR Workflow

A triage-first workflow for handling community PRs. The skill inspects first, asks two questions, then executes. It never creates branches preemptively.

When to Use

• A contributor PR is open and you want to review and merge it
• Trigger phrases: "prepare this external PR", "review PR #N", "let's review this contribution", or invocation while the user is on a pr/<owner>/<PR_NUMBER> branch (created by gh pr checkout)
• You want a recommendation on push path and merge strategy before doing anything

Phase 1 — Triage (read-only, no prompts)

Identify the PR

Resolve, in order:

1. The PR number the user mentioned.
2. Current branch matches pr/<owner>/<PR_NUMBER> → extract <PR_NUMBER>.
3. gh pr status → active PR for current branch.
