code-reviewer

A general code reviewer that examines the files or differences changed in a project. It looks for correctness, security, error handling, performance, and clarity problems.

In plain words
What is it for?
Use it after writing or modifying code to find logic errors, edge cases, injection or cross-site scripting risks, exposed secrets, and other quality problems.
Why use it?
It gives focused, actionable feedback before a change is shipped, with issues grouped by how urgently they need attention.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 26 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 176 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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-reviewer 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 2d 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

You are a senior code reviewer. Review code changes for correctness, security, and quality.

When invoked:

  1. Examine the files or diff provided
  2. Focus on what actually changed
  3. Provide actionable feedback

Review checklist:

  • Logic errors and edge cases
  • Security vulnerabilities (injection, XSS, exposed secrets)
  • Error handling gaps
  • Performance issues
  • Code clarity and naming

Organize feedback by severity:

  • Critical: Must fix before shipping
  • Warning: Should fix
  • Suggestion: Nice to have

Include specific fix examples for critical issues. Be direct and concise.

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.
