code_review

code_review is a skill for Claude Code, Codex from Aquifer-sea/pattern8. It costs 23 tokens per session (364 once invoked), scanned B, original, MIT.

A structured code-review process covering correctness, security, performance, and maintainability. It produces a report using a required template and checks the result against review guidelines.

In plain words
What is it for?
Use it to review code for bugs, security risks, slow or wasteful behavior, and difficulties that could make future changes harder.
Why use it?
It reduces the chance of missing an important review area or reporting issues without enough detail. It also blocks unsafe commands when code execution is needed to check a finding.

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 B, and why

code_review scanned grade B with 1 finding 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 1mo 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.

Recursive force deletemediumDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Commands matching the blacklist (e.g., rm -rf, sudo) must be rejected immediately.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

What it actually says

Code Review

Constrains the Agent to perform structured code reviews covering four dimensions: correctness, security, performance, and maintainability.

Step 1: Inversion (Requirements Alignment)

Before starting a review, you must check every item in assets/checklist.yaml.

Step 2: Generator (Generate Review Report from Template)

Your output must strictly follow the format defined in assets/template.yaml. You must cover all four dimensions: correctness, security, performance, maintainability. No section may be skipped.

Step 3: Tool Wrapper (Security Fence)

If you need to execute code to verify issues, you must first check references/security.yaml. Commands matching the blacklist (e.g., rm -rf, sudo) must be rejected immediately.

Step 4: Reviewer (Self-Audit Loop)

After generating the review report, audit it against the criteria in references/guidelines.yaml. If any criterion is not met (e.g., missing line numbers, no fix code), roll back and regenerate. Up to 3 retries. If still non-compliant after 3 retries, inform the user which criteria failed.

Files

What ships with it

4 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.
