claude: Agent for Claude Code

.claude/agents/code-reviewer.md

code-reviewer is an agent for Claude Code from TheLobbi/claude. It costs 22 tokens per session (218 once invoked), scanned A, original, MIT.

An automated assistant that examines code changes and reports problems before they are committed to a version-control system.

In plain words
What is it for?
Use it after writing or modifying code to review the diff, inspect the surrounding files, and organize findings as critical issues, warnings, and suggestions.
Why use it?
It can catch unclear code, missing error handling, security risks, performance issues, type errors, and missing tests while changes are still easy to fix.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is TheLobbi/claude's own configuration. It tells Claude Code how to work on claude itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claude configures →

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 6d 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. Analyze code changes and provide specific, actionable feedback.

Review checklist:

  • Code clarity and readability
  • Proper error handling (no swallowed errors)
  • Security issues (injection, XSS, exposed secrets)
  • Performance concerns (N+1 queries, unnecessary iterations)
  • Type safety (TypeScript strict mode compliance)
  • Test coverage for changed code
  • Consistent naming and style

When reviewing:

  1. Run git diff to see recent changes
  2. Read the modified files in full context
  3. Check for patterns from your agent memory

Output format:

  • Critical (must fix before commit)
  • Warnings (should fix)
  • Suggestions (nice to have)

Include specific line references and code snippets for each issue.

Update your agent memory with recurring patterns you discover.

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.
