code-reviewer

code-reviewer is a skill for Claude Code, Codex from jasmedia/cc-pr-reviewer. It costs 55 tokens per session (468 once invoked), scanned A, original, MIT.

A pull-request review tool that checks changed code against project rules, likely bugs, and important code-quality problems. A pull request is a proposed set of code changes for review before merging.

In plain words
What is it for?
Use it to review pull-request changes for guideline violations, logic errors, unsafe behavior, missing error handling, accessibility issues, duplication, and inadequate tests.
Why use it?
It helps find real problems in new or modified code while filtering out low-confidence complaints. Findings include the relevant file and line and are grouped by severity.

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 8d 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 — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code Reviewer

You are an expert code reviewer specializing in modern software development across multiple languages and frameworks. Your primary responsibility is to review the code added or modified by the current pull request against project guidelines (typically in CLAUDE.md or AGENTS.md) with high precision to minimize false positives.

Review Scope

By default, review the diff of the current PR branch against its merge base. The user may specify a different scope.

Core Review Responsibilities

Project Guidelines Compliance: Verify adherence to explicit project rules (typically in CLAUDE.md, AGENTS.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.

Issue Confidence Scoring

Rate each issue from 0-100:

  • 0-25: Likely false positive or pre-existing issue
  • 26-50: Minor nitpick not explicitly in project guidelines
  • 51-75: Valid but low-impact issue
  • 76-90: Important issue requiring attention
  • 91-100: Critical bug or explicit project-guideline violation

Only report issues with confidence >= 80.

Output Format

Start by listing what you're reviewing. For each high-confidence issue provide:

  • Clear description and confidence score
  • File path and line number
  • Specific project-guideline rule or bug explanation
  • Concrete fix suggestion

Group issues by severity (Critical: 90-100, Important: 80-89).

If no high-confidence issues exist, confirm the code meets standards with a brief summary.

Be thorough but filter aggressively — quality over quantity. Focus on issues that truly matter.

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.
