dart-manage-pr

Use this skill in Codex to run the DART dart-manage-pr workflow. The editable workflow source currently lives in .claude/commands/, and this generated Codex skill is a generated Codex adapter entrypoint.

Invocation

• Claude Code/OpenCode: /dart-manage-pr <arguments>
• Codex: $dart-manage-pr <arguments>

Treat the text after the skill name as $ARGUMENTS. When the workflow references $1, $2, etc., map those to the positional values supplied by the user.

Command Body

Manage an open DART pull request after explicit maintainer/user approval for mutations: $ARGUMENTS

Required Reading

@AGENTS.md @docs/onboarding/contributing.md @docs/onboarding/ci-cd.md @docs/onboarding/testing.md @docs/onboarding/ai-tools.md

Modes

• mode=manage (default): run the full PR-management loop below to the next terminal state.
• mode=merge: maintainer-only. Complete the local pre-merge validation in step 6 and merge a ready PR only after explicit maintainer/user approval for the merge.

Invocation Contract

When the user says manage <PR> or continue managing <PR> without limiting the request to status-only, treat that as approval to run the full PR-management loop to the next terminal state:

• required policy metadata checked and corrected when stale;
• CI monitored until green, failed, or blocked;
• merge conflicts reproduced and resolved locally;
• review comments addressed, pushed, resolved, and re-reviewed when appropriate;
• PR body/testing evidence refreshed when it no longer matches the branch.

This explicit approval covers routine PR-maintenance mutations for that loop: additive fix commits and pushes, PR description/metadata corrections, resolving already-addressed review threads, rerunning failed CI jobs, and requesting a fresh AI review after follow-up fixes. It does not cover merging the PR into the target branch, force-pushes, branch deletion, PR closure, base-branch changes, or human reviewer requests; ask separately for those.

Do not call the PR managed just because checks are green. Continue until the PR is mergeable with required checks complete and addressed review threads resolved, or until a concrete blocker remains.

Identify the PR

Use the PR number or URL from $ARGUMENTS. If none is provided, infer the PR from the current branch:

gh pr view --json number,url,headRefName,baseRefName

Then inspect the full state:

gh pr view <PR_NUMBER> --json number,title,state,isDraft,baseRefName,headRefName,mergeStateStatus,milestone,url,reviewDecision,statusCheckRollup
gh pr checks <PR_NUMBER>

Workflow

1. Confirm scope and policy:
   • Check that the base branch, title, and PR template are correct.
   • Verify the milestone is set before merge: DART 7.0 for a main base, the branch-matching DART 6.x patch milestone for a release-* base. If it is missing, set it only after explicit maintainer/user approval.
   • For bug fixes, verify the required DART 6 LTS + main dual-PR flow.
   • Confirm the PR body's testing/status section matches the current head and does not point reviewers to deleted dev-task evidence as still pending.
   • Confirm the PR body follows template order: Summary, Motivation / Problem, Changes / Key Changes, optional Before / After, Testing, Breaking Changes, and Related Issues / PRs. Keep Summary first as the skimmable outcome; fold leading problem context into Summary and keep the fuller why in Motivation.
   • When the PR has user-facing API, workflow, behavior, or performance impact, confirm a concise Before / After section compares old and new surfaces; for performance claims make the baseline explicit (CPU path, parent commit, main, or prior implementation) plus workload, metric, and limitations.
   • Ensure transient visual evidence (screenshots, headless renders, GIFs, videos) is hosted as GitHub PR/issue attachments rather than committed to the branch; if committed only for the PR body, replace it with an attachment URL or ask a maintainer to upload.
   • Inspect local state before editing:

     git status --short --branch
     git diff --stat
     git diff --check
     

2. Monitor CI:

   gh pr checks <PR_NUMBER> --watch --interval 30 --fail-fast
   

   If checks are still queued or running, report the current jobs and keep watching unless the user asked only for status. Also poll mergeability:

   gh pr view <PR_NUMBER> --json mergeStateStatus,headRefOid,isDraft,reviewDecision
   

   If GitHub reports conflicts, fetch the target branch and resolve them before treating green checks as sufficient.
3. Fix failures:
   • Inspect the newest failed run or job, not an older cancelled run. Use the dart-fix-ci workflow for non-trivial CI debugging.
   • Reproduce locally with the relevant pixi run ... task or focused test.
   • Before committing fixes, run pixi run lint; also build or test when code or behavior changed. Commit only intended files.
   • Prefer additive follow-up commits for published PRs. Amend or force-push only after explicit maintainer/user approval and only when the user requests it or a clear reason exists (removing sensitive content, repairing branch history).
   • Merge the latest base branch into the PR branch before any push, and follow the base-merge, automated-review, and bot no-reply rules in docs/onboarding/ai-tools.md; each push, PR comment, review re-trigger, or thread resolution needs explicit maintainer/user approval.
4. Address reviews:
   • Use the dart-review-pr workflow for substantive review feedback and the automated-review handling in docs/onboarding/ai-tools.md (no inline bot replies; verify claims locally; apply AI-review fixes silently).
   • For human reviewers, reply only when a response is useful after a fix or when a question needs clarification.
   • After an approved push that addressed Codex comments on a PR that already had a Codex review, post a fresh top-level @codex review; that PR comment needs explicit maintainer/user approval and must not duplicate an active trigger.
   • For substantive code PRs, an independent review session (a human, or a separate agent session running /dart-review-pr) must record findings before merge approval; docs-only and mechanical changes are exempt.
5. Mark ready or merge only when appropriate:
   • Confirm review requirements are satisfied and local validation matches the intended transition.
   • If the PR is draft, mark it ready after explicit approval once Codex is clean and local validation passed on the current head: default pixi run test-all, plus pixi run -e cuda test-all on Linux hosts with a visible NVIDIA CUDA runtime. Hosted CI may still be pending.
   • Use the current head SHA when merging so a moved branch cannot be merged accidentally. Prefer squash/rebase over merge commits per repository settings; recent DART main PRs use single-parent PR-title commits.
6. mode=merge gate (maintainer-only): before any merge, run local pre-merge validation on the current head after the latest pushed change: pixi run test-all and, on Linux hosts with a visible NVIDIA CUDA runtime, pixi run -e cuda test-all; do not substitute the default run for the CUDA run, and record a skip or blocker explicitly. Merge only after CI and review are green, the milestone is set, an independent review recorded findings, the PR is not draft, GitHub reports it mergeable, and explicit merge approval is given. PR comments, review re-triggers, thread resolution, reviewer requests, ready-for-review transitions, merges, and branch deletion are external mutations that require explicit maintainer/user approval.
7. Clean up after merge:
   • Confirm the PR merged and identify the head branch before deleting.
   • After explicit maintainer/user approval, prefer merge-time deletion with the approved merge method and head SHA:

     gh pr merge <PR_NUMBER> --squash --match-head-commit <HEAD_SHA> --delete-branch
     

     Use --rebase or --merge instead of --squash when requested.
   • After explicit maintainer/user approval, otherwise delete only the PR branch after confirming it has landed:

     git push origin --delete <HEAD_BRANCH>
     git switch main
     git pull --ff-only
     git branch -D <HEAD_BRANCH>
     

     Squash and rebase merges do not preserve the branch tip in main ancestry, so force-delete locally only after confirming the PR branch landed and only after explicit maintainer/user approval.

• Local pre-merge validation state when mode=merge ran.
• Commits pushed, merge action, and branch cleanup action.
• Remaining blockers or next action.
