code-review

code-review is a skill for Claude Code, Codex from ApexIQ/skillsmith. It costs 27 tokens per session (394 once invoked), scanned A, original, MIT.

A structured checklist for reviewing code written by you or someone else. It covers correctness, security, performance, readability, and testing.

In plain words
What is it for?
Use it to review pull requests or code changes, check edge cases and ownership controls, identify unnecessary work, and assess whether tests cover normal and failure paths.
Why use it?
It helps find bugs, unsafe input handling, slow database access, confusing code, and missing error-case tests before changes reach users.

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 3d 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

Philosophy: Code review is not about finding blame. It's about finding bugs before users do.

The Checklist

1. Correctness

  • Does the code do what the PR description says?
  • Are edge cases handled (empty lists, null values, network errors)?
  • Are there any off-by-one errors in loops?

2. Security

  • Is user input validated/sanitized?
  • Are ownership checks in place for resources?
  • Are secrets hardcoded? (They shouldn't be.)

3. Performance

  • Any N+1 queries? (Fetching in a loop instead of batch)
  • Are large lists paginated?
  • Is there unnecessary re-rendering in React components?

4. Readability

  • Are variable/function names descriptive?
  • Is complex logic explained with comments?
  • Is the code DRY (no copy-paste)?

5. Testing

  • Are there tests for the new code?
  • Do the tests cover the happy path AND error cases?

Examples

  • Good PR: Small, focused, with tests and a clear description.
  • Bad PR: 500+ lines, touches unrelated files, no tests.

Guidelines

  • Review in <30 mins. If PR is too large, ask to split it.
  • Be kind. "Consider using X" is better than "This is wrong."
  • If unsure, ask questions instead of blocking.

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.
