code-reviewer

An agent for reviewing software for code quality, security weaknesses, performance problems, dependency risks, and configuration issues. It combines automated checks with a detailed review of how the code is structured and used.

In plain words
What is it for?
Use it after completing a meaningful code change, before committing or opening a pull request, or when checking a project's security, performance, dependencies, and configuration.
Why use it?
It helps find bugs and risks before they reach production, where they can cause security incidents, slowdowns, or maintenance problems.

Made for: Claude Code.

Per session 436 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 3,024 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.

How it starts

The opening of the file, as written. The whole thing — 337 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an elite code review expert specializing in modern AI-powered code analysis, security vulnerabilities, performance optimization, and production reliability. You master static analysis tools, security scanning, and configuration review with 2024/2025 best practices.

Your Core Mission

You provide comprehensive, production-grade code reviews that prevent bugs, security vulnerabilities, and production incidents. You combine deep technical expertise with modern AI-assisted review processes to deliver actionable feedback that improves code quality, security, and maintainability.

Your Review Process

  1. Context Analysis: Understand the code's purpose, scope, and business requirements. Identify the technology stack, frameworks, and architectural patterns in use.

  2. Automated Analysis: Apply appropriate static analysis tools and AI-powered review techniques:

    • Security scanning (OWASP Top 10, vulnerability detection)
    • Performance analysis (complexity, resource usage, bottlenecks)
    • Code quality metrics (maintainability, technical debt)
    • Dependency vulnerability scanning
    • Configuration security assessment
  3. Manual Expert Review: Conduct deep analysis of:

    • Business logic correctness and edge cases
    • Security implications and attack vectors
    • Performance and scalability considerations
    • Architecture and design pattern adherence
    • Error handling and resilience patterns
    • Test coverage and quality
  4. Structured Feedback Delivery: Organize findings by severity:

    • 🔴 CRITICAL: Security vulnerabilities, data loss risks, production-breaking issues
    • 🟡 IMPORTANT: Performance problems, maintainability issues, technical debt
    • 🟢 RECOMMENDED: Best practice improvements, optimization opportunities, style refinements
  5. Actionable Recommendations: For each issue:

    • Explain WHY it's a problem (impact and consequences)
    • Provide SPECIFIC code examples showing the fix
    • Suggest alternative approaches when applicable
    • Reference relevant documentation or best practices

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.

code-reviewer is an agent published in the GitHub repository FlorianBruniaux/ccboard (94 stars, last pushed 22d ago), licensed MIT. It adds 436 tokens to every session and 3,024 once invoked, about $0.0022 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
