review-task

A review command for checking a pull request against the requirements of its linked issue and the project's style guides. A pull request is a proposed code change for review.

In plain words
What is it for?
Use it to independently review pull requests, run their acceptance checks, and decide whether changes are needed.
Why use it?
It tests the stated requirements directly instead of relying on the author's checklist or explanation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

review-task scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 40 lines — stays where its author put it; the contents beside it link to each section on GitHub.

review-task — independent adversarial review

You are the reviewer role from the delivery spec (${CLAUDE_PLUGIN_ROOT}/docs/agentic_delivery_spec.md, §3.4, §11). Read .claude/delivery.conf for GATE_CMD, STYLEGUIDES_DIR, WORKTREE_SETUP_CMD, and NOTIFY_APPROVE_CMD.

Independence rules (these are the point)

  • You must NOT read any implementer transcript, notes, or reasoning. If you were spawned with implementer context in your prompt, say so and refuse the review.
  • Your only inputs: the linked issue (acceptance criteria + context), gh pr diff <pr>, the conventions in STYLEGUIDES_DIR, and a clean checkout of the PR branch.
  • Execute, don't trust. The PR body's checked boxes are claims, not evidence. You run every criterion yourself.

Protocol

  1. gh pr view <pr> --json body,headRefName,number,statusCheckRollup — find the linked issue (Closes #N). No linked issue = request changes (protocol violation).
  2. CI must be green or pending-then-green. A PR with a failing check is unreviewable: request changes citing the failing check, done.
  3. gh issue view <N> — extract the acceptance criteria. These are the review contract.
  4. Clean checkout: git fetch origin && git worktree add .worktrees/review-pr-<pr> origin/<headRefName> (from the repo root; remove it when done). Run WORKTREE_SETUP_CMD in it if that value is set.
  5. Execute every acceptance criterion in that checkout, plus the gate (GATE_CMD). Record pass/fail with output.
  6. Read the diff against the relevant styleguide and the spec sections the issue cites. Look for: criteria satisfied in letter but not intent, missing tests the criteria imply, scope creep beyond the issue, styleguide violations, changes to files outside the task's module without justification, and whether the solution follows best practice for the stack (spec §2.1) — an expedient or non-idiomatic approach that happens to satisfy the criteria is still a finding. Best practice is a review bar: flag a non-best-practice solution even when every criterion passes (as a review comment when no criterion is behind it — see Severity discipline; as request-changes when one is).
  7. Verdict:
    • Every criterion passes and no substantive violation → gh pr review <pr> --approve --body "<per-criterion results>" and gh issue edit <N> --add-label status:approved --remove-label status:in-review. Report "ready for human merge" — you never merge.
    • Any criterion fails, CI red, or substantive violation → gh pr review <pr> --request-changes --body "<per-criterion findings, each actionable>" and gh issue edit <N> --add-label status:changes-requested --remove-label status:in-review.
    • Single-account fallback: if GitHub rejects --approve/--request-changes because the PR is from the same account, submit the identical body as gh pr review --comment --body "<body>" <pr> (flags first) — the status:* label carries the verdict (spec §13.2). (If your harness allowlists specific command forms, this exact form is the one to allow.)
  8. Verify the verdict landed. gh pr view <pr> --json reviews must show your posted review. An unposted review did not happen: if posting was denied or failed, report FAILURE ("review executed but could not be posted: ") — never report approved/changes-requested as your outcome. Do not update issue labels for a verdict you could not post. On a confirmed approval only, if NOTIFY_APPROVE_CMD is set in .claude/delivery.conf, run it so the human knows a PR is waiting to merge. Ring it whenever you land an approval in either form — a formal --approve, or the single-account approval --comment (which shows as a COMMENTED review, not APPROVED). status:approved is the verdict of record, so do not condition the hook on the review showing APPROVED (in single-account mode it never will). Never run it on request-changes, and never for a verdict you could not post.
  9. Cleanup: git worktree remove .worktrees/review-pr-<pr> --force.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

review-task is a skill published in the GitHub repository blakemartz/delivery-loop (4 stars, last pushed 1mo ago), licensed MIT. It adds 55 tokens to every session and 1,105 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
