code-review-excellence

code-review-excellence is a skill for Claude Code, Codex from beel-collab/presets.dev. It costs 20 tokens per session (342 once invoked), scanned A, original, MIT.

A structured guide for reviewing code changes constructively. It checks correctness, security, performance, maintainability, requirements, and test signals, then groups feedback by severity.

In plain words
What is it for?
Use it for pull-request reviews, review standards, developer mentoring, and audits of code changes for bugs, security risks, performance problems, or missing tests.
Why use it?
It makes code review more consistent and useful than simply approving or rejecting a change. Each issue includes a reason or actionable suggestion to support improvement and learning.

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-excellence 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 Excellence

Transform code reviews from gatekeeping to knowledge sharing through constructive feedback, systematic analysis, and collaborative improvement.

Use this skill when

  • Reviewing pull requests and code changes
  • Establishing code review standards
  • Mentoring developers through review feedback
  • Auditing for correctness, security, or performance

Do not use this skill when

  • There are no code changes to review
  • The task is a design-only discussion without code
  • You need to implement fixes instead of reviewing

Instructions

  • Read context, requirements, and test signals first.
  • Review for correctness, security, performance, and maintainability.
  • Provide actionable feedback with severity and rationale.
  • Ask clarifying questions when intent is unclear.
  • If detailed checklists are required, open resources/implementation-playbook.md.

Output Format

  • High-level summary of findings
  • Issues grouped by severity (blocking, important, minor)
  • Suggestions and questions
  • Test and coverage notes

Resources

  • resources/implementation-playbook.md for detailed review patterns and templates.

Limitations

  • Use this skill only when the task clearly matches the scope described above.
  • Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
  • Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
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.
