code-review

A protocol for reviewing code and giving a consistent decision about its quality and readiness. It checks whether the code works, is maintainable, handles unusual cases, and avoids obvious security or performance problems.

In plain words
What is it for?
Use it to understand the intended change, inspect relevant files, record a summary and recommendations in a review document, and finish with a pass-or-fix verdict.
Why use it?
It gives reviews a repeatable structure and makes findings easier to act on, with specific issues and file or line references.

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

code-review 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.

What it actually says

Code Review Skill

You are performing a code review. Follow this protocol for consistent, actionable feedback.

Review Process

Step 1: Understand the Context

  • Read the project brief and any related documentation in the workspace
  • Understand what the author was trying to accomplish
  • Check team_roster.json to know who wrote what

Step 2: Review the Code

  • Read all relevant files in the workspace
  • Check for:
    • Correctness — Does the code do what it's supposed to?
    • Quality — Is it readable, maintainable, well-structured?
    • Edge cases — Are there unhandled scenarios?
    • Security — Any obvious security issues?
    • Performance — Any obvious performance problems?

Step 3: Write Your Review

Write your review to: reviews/<step_name>_review.md

Include:

  1. Summary — Overall assessment
  2. Issues found — Specific problems with file/line references
  3. Suggestions — Improvements that aren't blockers
  4. Verdict — Your final decision

Step 4: Declare Verdict

Always end your review with one of these exact strings:

✅ When code is acceptable:

[DECISION] VERDICT: PASS — <brief reason>

❌ When code needs fixes:

[DECISION] VERDICT: FAIL — <brief reason with key issues>

Communication

After writing your review:

  • Use send_email(to="<author_name>", body="...", my_name="<your_name>") to notify the author
  • Include a summary of key issues if FAIL
  • Be constructive — suggest fixes, don't just point out problems

As a Code Author (receiving review)

When you receive a FAIL verdict:

  1. Read the review feedback carefully
  2. Fix the identified issues in your workspace files
  3. Message the reviewer: send_email(to="<reviewer_name>", body="Fixes applied, ready for re-review", my_name="<your_name>")
Changes

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.
