review-rubric

review-rubric is a skill for Claude Code, Codex from telus-labs/stagecraft. It costs 58 tokens per session (789 once invoked), scanned A, original, MIT.

A checklist for reviewing a code change against its specification, behaviour, security, tests, readability, and performance.

In plain words
What is it for?
Use it during peer review to classify findings as blockers or suggestions and decide whether the change is approved or needs changes.
Why use it?
It gives reviewers a consistent way to find broken behaviour, missing tests, security problems, and unexplained differences from the requested design.

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-rubric 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 10d 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.

Review Rubric

Use this skill when performing a code review. It defines the standard review checklist every reviewer must work through.

Mandatory Checks (every review)

1. Spec Compliance

  • Does the code match pipeline/design-spec.md?
  • Are all API contracts implemented as specified?
  • Are there undocumented deviations? (BLOCKER if unexplained)

2. Correctness

  • Are all edge cases from the spec handled?
  • Are error paths handled and tested?
  • Are there off-by-one errors, null dereferences, or type mismatches?

3. Security

  • No secrets in code
  • Input validation present
  • Auth checks in place where spec requires them
  • No SQL string concatenation

4. Test Coverage

  • Does new behaviour have corresponding tests?
  • Do tests actually test the behaviour (not just call the function)?

5. Readability

  • Can a new team member understand this code in 5 minutes?
  • Are complex sections commented?

Comment Classification

Every review comment must be one of:

BLOCKER — Must be fixed before this PR can merge. Use for: security issues, missing tests, spec violations, broken behaviour.

SUGGESTION — Would improve the code. Author's call. Use for: style preferences, minor optimisations, naming improvements.

QUESTION — Need clarification. Not blocking unless answered badly. Use for: unclear intent, possible oversight, design question.

Verdict

REVIEW: APPROVED — No blockers. May have suggestions. REVIEW: CHANGES REQUESTED — One or more blockers. List them.

Scope

This rubric is for pipeline Stage 5 peer reviews — when dev agents review each other's PRs during a /pipeline run. For standalone pre-merge review of changes made outside the pipeline (direct edits, implement skill work, /hotfix runs), use the pre-pr-review skill instead.

Gotchas (add failures here over time)

  • Do not approve a PR just because it "looks fine". Work through the checklist.
  • Do not raise the same point another reviewer already raised (read their review first).
  • Do not BLOCKER a style preference. That's what linters are for.

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.
