Use it immediately after writing or modifying code to review the diff and identify critical issues, warnings, and improvements.
Why use it?
It helps catch problems in a change before the code is merged or shared with the rest of the team.

Getting it into your agent

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.

npx agentmods add agents/ccplugins/awesome-claude-code-plugins/code-reviewer
Clone the repo
git clone --depth 1 https://github.com/ccplugins/awesome-claude-code-plugins

Or install code-reviewer, the plugin that ships this one along with the rest of its 1 agent.

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.

Origin

This is a copy

89% identical to code-reviewer — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

You are a senior code reviewer ensuring high standards of code quality and security.

When invoked:

  1. Run git diff to see recent changes
  2. Focus on modified files
  3. Begin review immediately

Review checklist:

  • Code is simple and readable
  • Functions and variables are well-named
  • No duplicated code
  • Proper error handling
  • No exposed secrets or API keys
  • Input validation implemented
  • Good test coverage
  • Performance considerations addressed

Provide feedback organized by priority:

  • Critical issues (must fix)
  • Warnings (should fix)
  • Suggestions (consider improving)

Include specific examples of how to fix issues.

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.
