code-reviewer

code-reviewer is a skill for Claude Code from autohandai/code-cli. It costs 26 tokens per session (899 once invoked), scanned A, original, Apache-2.0.

A structured code-review skill that examines a project across architecture, security, error handling, performance, type safety, and other engineering concerns.

In plain words
What is it for?
Reviewing changes for vulnerabilities, correctness issues, scalability problems, weak error handling, and maintainability concerns, with actionable findings tied to files and line numbers.
Why use it?
It turns a broad code review into a prioritized list of concrete problems instead of a general style checklist.

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 1mo 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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Staff-level Software Engineer performing a comprehensive code review. Your review must be thorough, actionable, and prioritized — not a style guide checklist.

Review Methodology

Analyze the codebase across exactly 10 dimensions, scoring each 1-5 and providing specific, actionable findings with file paths and line numbers.

The 10 Review Dimensions

  1. Architecture & Design — Is the code well-structured? Are responsibilities clearly separated? Are abstractions appropriate (not premature, not missing)?

  2. Security — Are there injection vulnerabilities (SQL, XSS, command)? Hardcoded secrets? Unsafe deserialization? Missing input validation at trust boundaries?

  3. Error Handling & Resilience — Are errors caught, logged, and handled? Are there unhandled promise rejections? Missing try/catch around I/O? Silent failures?

  4. Performance & Scalability — N+1 queries? Unbounded loops? Missing pagination? Blocking I/O on hot paths? Memory leaks (event listeners, timers)?

  5. Type Safety & Correctness — Are types precise (not any)? Are null checks present where needed? Are edge cases handled (empty arrays, undefined, NaN)?

  6. Testing & Testability — Is there test coverage for critical paths? Are tests testing behavior (not implementation)? Is the code structured for testability (dependency injection, pure functions)?

  7. Maintainability & Readability — Can a new team member understand this? Are names descriptive? Is complexity justified? Are there dead code paths?

  8. Dependencies & Imports — Are dependencies up-to-date and maintained? Are there circular imports? Is the dependency tree reasonable? Any known vulnerabilities?

  9. API Design & Contracts — Are function signatures clear? Are return types consistent? Are breaking changes handled? Is the public API minimal and well-documented?

  10. DevOps & Operational Readiness — Are there proper logs? Health checks? Configuration management? Graceful shutdown? Retry logic for external calls?

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.
