XQUIC PR Formatting

This skill owns contributor-facing PR content, summary-to-code consistency, and PR state checks. It does not own local staging, commits, branch pushes, CI diagnosis, review-comment fixes, or code review.

Required Workflow

1. Read CONTRIBUTING.md and the pull-request specification.
2. Start from the repository pull-request template.
3. Build and validate the title with the exact shape from Pull Request Title: use [<change-id>] Fix #<issue-number>: <concise English summary> when closing an issue, or [<change-id>]: <concise English summary> otherwise. Allow only +, -, =, or ~ as the change identifier. Use one concise English sentence that describes the core change.
4. Treat the template's three concise sections as the canonical PR body structure: mechanism, validation cases, and aggregate CONTRIBUTING.md status.
5. Check the branch name against the task-to-prefix mapping in CONTRIBUTING.md, then check commit format, CLA state, rebase and squash state, code style, complete-unit-suite result, relevant tests, CI state, and issue-closing syntax.
6. Explain the changed mechanism and cite the exact RFC or draft section for protocol behavior. Include the exact Fixes: #<issue-number> line for an issue fix.
7. Verify internally that the complete local unit suite passed; a focused unit test is insufficient. In the PR, list only executed client-to-server case IDs and concise behavior, or concise missing case evidence.
8. For new case IDs, require a fresh, conflict-free reservation scan across every other open PR's published head. Keep successful scan details in local evidence; expose only a concise blocker when a conflict exists.
9. Check every CONTRIBUTING.md item internally. Publish one overall result, Local regression: Complete or concise failed cases, and CI: Complete or only incomplete check names.
10. Write multiline descriptions or comments to a Markdown file first.
11. After the development pipeline's validation gate passes and the branch is already pushed, create every new code pull request as draft through the available GitHub client using that file. Keep follow-up updates in draft unless the active task is to move the current published head toward review.
12. After any code push changes the published PR head, rerun this skill against the current base-to-head diff before the PR is updated or moved forward. Update the mechanism, validation cases, and aggregate gate summary so they describe the current code and validation evidence, not a prior head.
13. Fetch the published pull request and confirm its number, URL, base, head, canonical title, body, real line breaks, and draft state.
14. Verify the published PR summary matches the current base-to-head diff: changed mechanism, protocol citations, issue linkage, case IDs, local gate, and CI status must all be current and source-backed.
15. When the active task is to move a code PR out of draft, run xquic-pr-pre-review against the published pull request. Read ~/build/harness/pr-review-<number>/pr-review-<number>.md and require pre_review_result: true for its exact published head. Keep the report out of the commit and concise PR body. Preserve its sibling abnormal-case artifacts as local inputs to the next PR iteration.
16. When moving a PR toward review, immediately repeat the reservation scan with the published current PR included. If duplicate case IDs exist, the lowest PR number keeps them. Keep or return every later PR to draft and send it back through allocation and validation before another update.
17. Reflect a collision as an incomplete local gate; keep successful details out of the body. Fetch the published pull request and verify its title, concise body, real line breaks, RFC and issue links, aggregate statuses, base, head, draft or review state, and URL. Update the concise body and move an otherwise complete PR to review only after this check passes.

Pull Request Body

Use .github/pull_request_template.md as the single body shape. Do not add per-check checklists or validation transcripts. Use Not applicable with a short reason when protocol or runtime cases do not apply.

List cases only as:

<case ID> — <concise behavior>

Pull Request Title

Use [<change-id>] Fix #<issue-number>: <concise English summary> for an issue-closing pull request and [<change-id>]: <concise English summary> otherwise. The marker is one of +, -, =, or ~. Summarize the core change in one concise English sentence and use GitHub's draft state instead of adding status prefixes to the title.

Guardrails

• Keep claims factual and source-backed.
• Keep the PR body concise; detailed evidence belongs in code, CI, or ignored local validation artifacts.
• Do not publish a title that omits the canonical change marker, uses another issue syntax, or contains a non-English description.
• Do not use escaped newline strings for multiline GitHub content.
• Do not claim the complete local unit suite passed when only a focused test ran.
• Do not leave a PR summary describing an older head after code changes are pushed.
• Do not move a production code pull request to review without required unit coverage and accepted local gate evidence.
• Do not submit a new production code pull request before the development pipeline's validation gate passes, and do not create it initially as ready.
• Do not move a production code pull request to review before its exact published current head passes pre-review.
• Do not accept a missing, stale, false, or inconclusive pre-review report.
• Do not publish or update a ready-for-review production PR with a case ID reserved by another open PR.
• Do not treat a failed or incomplete open-PR query as an empty reservation set.
• Do not leave the later-numbered PR ready after a post-publication collision; reallocate its ID and rerun validation.
• Do not publish detailed commands, test function names, case names, logs, namespace ranges, tested SHA, or successful reservation snapshots.
• Do not mark the aggregate CONTRIBUTING.md result passed when the branch, commits, CLA, rebase state, style, local regression, CI, or issue syntax does not support it.
• Do not accept an allowed branch prefix when it belongs to a different task type.
• Do not include internal agent names, temporary artifacts, or process chatter in contributor-facing content.
• Do not stage, commit, push, rebase, or force-push while acting only on PR formatting or state.
• Preserve the distinction between issue-independent harness work and a product change that happens to exercise it.
