Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00974 |
| Opus 5.5 | $0.00000 | $0.00390 |
| Sonnet 5.5 | $0.00000 | $0.00195 |
| Haiku 4.5 | $0.00000 | $0.00097 |
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 2mo 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 — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Code Reviewer Skill
A comprehensive code review skill that analyzes code quality, security, performance, and best practices.
When to Use
Invoke this skill when:
- User asks to review code or a pull request
- User requests code quality analysis
- User wants security or performance audit
- Commands:
/review,/code-review,/pr-review
Capabilities
1. Code Quality Analysis
- Dead code detection
- Unused imports/variables
- Code duplication (DRY violations)
- Complexity metrics (cyclomatic complexity)
- Function/method length analysis
- Naming conventions
2. Security Review
- SQL injection vulnerabilities
- XSS vulnerabilities
- Command injection risks
- Hardcoded secrets/credentials
- Insecure dependencies
- Authentication/authorization issues
- Input validation gaps
3. Performance Analysis
- N+1 query detection
- Inefficient algorithms
- Memory leaks
- Unnecessary re-renders (React)
- Bundle size concerns
- Caching opportunities
4. Best Practices
- SOLID principles adherence
- Design pattern usage
- Error handling
- Logging practices
- Test coverage gaps
- Documentation completeness
Review Process
Step 1: Understand Context
1. Identify the language/framework
2. Understand the purpose of the code
3. Check for existing patterns in the codebase
4. Review any related tests
Step 2: Systematic Review
Use the checklist at checklist.md to perform a thorough review.
Step 3: Categorize Findings
| Severity | Description | Action Required |
|---|---|---|
| Critical | Security vulnerabilities, data loss risks | Must fix before merge |
| High | Bugs, significant performance issues | Should fix before merge |
| Medium | Code quality issues, minor bugs | Consider fixing |
| Low | Style issues, minor improvements | Optional |
| Info | Suggestions, alternative approaches | For consideration |
Step 4: Provide Actionable Feedback
What ships with it
1 file 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.
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 hackermanishackerman/claude-skills-vault (2 stars, last pushed 24d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 974 tokens. 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 2026-08-31.
