code-reviewer

A code-review helper that examines code for bugs, security problems, quality issues, and performance concerns. It gives feedback with suggested improvements and ranks issues by seriousness.

In plain words
What is it for?
Use it to review pull requests or inspect code for problems such as null-pointer errors, SQL injection, weak access controls, repeated database queries, unnecessary loops, and memory leaks.
Why use it?
It helps catch mistakes that may be missed during normal development, such as unsafe input handling, exposed secrets, missing error handling, or inefficient database access.

Made for: Claude Code, Codex.

Per session 19 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.
When invoked 184 The whole file, excluding the scripts and references it only reads on demand.

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.

What it actually says

Code Reviewer

This skill helps you review code for common issues.

When to Use

Use this skill when:

  • Reviewing pull requests
  • Checking code quality
  • Looking for security vulnerabilities

Guidelines

  1. Always check for:

    • Null pointer exceptions
    • SQL injection vulnerabilities
    • Hardcoded secrets
    • Missing error handling
  2. Provide constructive feedback with suggestions

  3. Prioritize issues by severity

Examples

Example 1: Security Review

When asked "review this code for security issues", focus on:

  • Input validation
  • Authentication/authorization
  • Data sanitization

Example 2: Performance Review

When asked about performance, check for:

  • N+1 queries
  • Unnecessary loops
  • Memory leaks
Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

code-reviewer is a skill published in the GitHub repository hidai25/eval-view (133 stars, last pushed 10d ago), licensed Apache-2.0. It adds 19 tokens to every session and 184 once invoked, about $0.0001 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.
