A structured review checklist for changed code. It examines simplicity, completeness, correctness, style, security, performance, and how easy the code is to test.

In plain words
What is it for?
Use it to review a code diff, check edge cases and error paths, find unused or incomplete code, and compare changes with project standards.
Why use it?
It helps catch bugs, missing error handling, unfinished code, unsafe inputs, and inconsistencies that may be overlooked in a quick review.

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 9d 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.

Code Review

Apply this structured review to every file changed in the diff or opened for review.

1. Simplicity Check (rules/structure.md)

  • Each function does one thing? (SRP)
  • No unnecessary abstractions? (no Strategy pattern for one-line math)
  • Fits on one screen? (< 40 lines per function)

2. Completeness Check (rules/completeness.md)

  • Any // TODO, FIXME, XXX, pass, NotImplementedError?
  • Any console.log, print(), debugger statements?
  • Any unused imports or variables introduced by these changes?
  • Any commented-out code or unreachable branches introduced by these changes?
  • Any pre-existing dead code that should be flagged to the user?
  • Every switch/match has a default/exhaustive case?
  • Parallel if/else branches (non-guard-clauses) handle all paths?

3. Correctness Check (rules/correctness.md)

  • All error paths handled? (no except: pass, no empty catch)
  • Edge cases covered? (null, empty, zero, boundary values)
  • Inputs validated?
  • Security risks? (injection, hardcoded secrets)

4. Style Check (rules/style.md)

  • Matches existing project style?
  • Formatter would pass? (Prettier, ruff, gofmt, etc.)
  • Imports at top?

5. Naming Check (rules/naming.md)

  • Names meaningful and in English? (calculate_total not calc)
  • Boolean prefixes? (is_, has_, should_)
  • Language-idiomatic? (snake_case for Python, camelCase for JS)

6. Performance Check (rules/performance.md)

  • N+1 queries in loops?
  • Unnecessary allocation inside loops?
  • Eager loading when lazy would do?

7. Testability Check (rules/testability.md)

  • Logic testable without excessive mocking?
  • Side effects isolated?

8. Async Check (rules/async.md)

  • Every promise/async handled? No fire-and-forget?
  • Resources cleaned up? (connections, handles, streams)

9. Documentation Check (rules/documentation.md)

  • Comments explain why, not what?
  • No obvious comments for self-explanatory code?
  • New modules or projects include execution instructions?

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.
