Procedure

1. Before changing directories, resolve investigation-root, reviews/, and .github/skills/shared/review-vcpkg-pr-guide.md against the caller's original directory to absolute paths. Keep the resolved reviews directory as reviews-root; never rebase it onto a worker's workspace.
2. Discover candidates using GitHub search (gh api or the Search API), not the generic pulls list: repo:microsoft/vcpkg is:pr is:open draft:false updated:>=<today minus 30 days>. Prefer authentication via gh or GITHUB_TOKEN to avoid low unauthenticated limits.
3. Fetch each candidate's changed files; identify ports from ports/<portname>/.
4. Prepare isolated workspaces as below. Review every candidate independently with a general-purpose worker using its default high-capability model; do not override it with a fast or lightweight model. Require it to read the entire guide and follow every instruction. Group competition only in the final index. Pass each worker:
   • PR number ({{PR_NUMBER}}).
   • Selected review-depth.
   • Absolute workspace and worker-local investigation-root.
   • Absolute {{REPORT_DIR}} (pr-{{PR_NUMBER}} under reviews-root).
   • Absolute guide path.
5. Write each report when completed. Write index.md last from the final per-PR results and port-specific competition groups.

Parallel execution safety

1. Give each concurrent worker its own writable detached worktree or equivalent detached-HEAD workspace and intermediate artifacts under investigation-root. Never share a writable repository path between workers.
2. Create all isolated workspaces before launching workers. Copy the caller's vcpkg.exe (Windows) or vcpkg (non-Windows) into each workspace root.
3. Use the caller's working tree only when exactly one worker is active and the user explicitly allows it.
4. If VCPKG_DOWNLOADS is already nonempty, preserve it for all workers and review commands. Use that shared directory only through vcpkg; never clean or delete it. Otherwise, do not set it.

index.md content

index.md must include:

1. Coverage summary, including how many PRs were reviewed, skipped, or failed.
2. PRs grouped by the shared guide's verdicts: approve, approve-with-notes, request-changes, and unknown, with relative links to their reports.
3. Competing PRs grouped only by the specific modified ports they share.
4. PRs with no touched ports/<portname>/ entries.
5. PRs that failed to review, with a short reason instead of silently omitting them.

Required output layout

Write only final deliverables under the fixed reviews-root, not under investigation-root:

1. index.md at reviews-root.
2. report.md in each worker's {{REPORT_DIR}}, including the guide's self-contained ## Fix handoff for use without this session's chat history.
3. patches/*.patch in each worker's {{REPORT_DIR}} -- only for examples-and-patches; omit if no patches were produced and explain any unpatched issues in the report.

Do not stop until the index and every reviewed PR's report exist at these absolute destinations and are complete.
