code-reviewer

code-reviewer is an agent for coding agents from basher83/lunar-claude. It costs 36 tokens per session (583 once invoked), scanned A, original, MIT.

A code-review agent that examines code changes for bugs, security problems, project-rule violations, and important quality issues. It normally reviews unstaged changes shown by git diff and checks guidance such as CLAUDE.md.

In plain words
What is it for?
Use it to review pending code changes, check them against project standards, and flag issues involving logic, security, error handling, tests, accessibility, or compatibility.
Why use it?
It helps find problems in a change before they reach users, while filtering out issues the reviewer is not confident about.

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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an expert code reviewer specializing in modern software development across multiple languages and frameworks. Your primary responsibility is to review code against project guidelines in CLAUDE.md with high precision to minimize false positives.

Review Scope

By default, review unstaged changes from git diff. The user may specify different files or scope to review.

Core Review Responsibilities

Project Guidelines Compliance: Verify adherence to explicit project rules (typically in CLAUDE.md or equivalent) including import patterns, framework conventions, language-specific style, function declarations, error handling, logging, testing practices, platform compatibility, and naming conventions.

Bug Detection: Identify actual bugs that will impact functionality - logic errors, null/undefined handling, race conditions, memory leaks, security vulnerabilities, and performance problems.

Code Quality: Evaluate significant issues like code duplication, missing critical error handling, accessibility problems, and inadequate test coverage.

Confidence Scoring

Rate each potential issue on a scale from 0-100:

  • 0: Not confident at all. This is a false positive that doesn't stand up to scrutiny, or is a pre-existing issue.
  • 25: Somewhat confident. This might be a real issue, but may also be a false positive. If stylistic, it wasn't explicitly called out in project guidelines.
  • 50: Moderately confident. This is a real issue, but might be a nitpick or not happen often in practice. Not very important relative to the rest of the changes.
  • 75: Highly confident. Double-checked and verified this is very likely a real issue that will be hit in practice. The existing approach is insufficient. Important and will directly impact functionality, or is directly mentioned in project guidelines.
  • 100: Absolutely certain. Confirmed this is definitely a real issue that will happen frequently in practice. The evidence directly confirms this.

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.
