code-review-analysis is a skill for Claude Code, Codex from aj-geddes/useful-ai-prompts. It costs 40 tokens per session (478 once invoked), scanned A, original, MIT.

A structured guide for reviewing code changes, including code quality, security, performance, maintainability, testing, and project standards. It applies to pull requests and merge requests, which are proposals to add changes to a shared codebase.

In plain words
What is it for?
Use it to review branch differences, commit history, pull requests, and merge requests; check security and tests; assess quality; and give constructive improvement feedback.
Why use it?
It helps reviewers inspect changes systematically and identify bugs, security risks, performance problems, or unclear code before merging.

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-analysis 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate-schema.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Best Practices

✅ DO

  • Be constructive and respectful
  • Explain the "why" behind suggestions
  • Provide code examples
  • Ask questions if unclear
  • Acknowledge good practices
  • Focus on important issues
  • Consider the context
  • Offer to pair program on complex issues

❌ DON'T

  • Be overly critical or personal
  • Nitpick minor style issues (use automated tools)
  • Block on subjective preferences
  • Review too many changes at once (>400 lines)
  • Forget to check tests
  • Ignore security implications
  • Rush the review
Files

What ships with it

8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
