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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00056 | $0.00808 |
| Opus 5 | $0.00028 | $0.00404 |
| Sonnet 5 | $0.00011 | $0.00162 |
| Haiku 4.5 | $0.00006 | $0.00081 |
Grade A, and why
code-auditor 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 11d 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.

Code Auditor
Comprehensive codebase analysis covering architecture, code quality, security, performance, testing, and maintainability.
When to Use
- "audit the code"
- "analyze code quality"
- "check for issues"
- "review the codebase"
- "find technical debt"
- "security audit"
- "performance review"
What It Analyzes
1. Architecture & Design
- Overall structure and organization
- Design patterns in use
- Module boundaries and separation of concerns
- Dependency management
- Architectural decisions and trade-offs
2. Code Quality
- Complexity hotspots (cyclomatic complexity)
- Code duplication (DRY violations)
- Naming conventions and consistency
- Documentation coverage
- Code smells and anti-patterns
3. Security
- Common vulnerabilities (OWASP Top 10)
- Input validation and sanitization
- Authentication and authorization
- Secrets management
- Dependency vulnerabilities
4. Performance
- Algorithmic complexity issues
- Database query optimization
- Memory usage patterns
- Caching opportunities
- Resource leaks
5. Testing
- Test coverage assessment
- Test quality and effectiveness
- Missing test scenarios
- Testing patterns and practices
- Integration vs unit test balance
6. Maintainability
- Technical debt assessment
- Coupling and cohesion
- Ease of future changes
- Onboarding friendliness
- Documentation quality
Approach
- Explore using Explore agent (thorough mode)
- Identify patterns with Grep and Glob
- Read critical files for detailed analysis
- Run static analysis tools if available
- Synthesize findings into actionable report
Thoroughness Levels
- Quick (15-30 min): High-level, critical issues only
- Standard (30-60 min): Comprehensive across all dimensions
- Deep (60+ min): Exhaustive with detailed examples

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-auditor is a skill published in the GitHub repository mhattingpete/claude-skills-marketplace (671 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 56 tokens to every session and 808 once invoked, about $0.0003 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.

verify-implementation
A workflow that runs a project’s verification skills to produce a report on coding patterns, architecture rules, and project conventions. It is intended for work after implementation, before a pull request, or during code review.
review-loop
Run the adversarial verification loop — implement, then hand the change to a fresh checker that did not write it, fix what it finds, and re-dispatch until APPROVE. Use before claiming any behavioural change is done, and on requests like "review loop", "adversarial review", "independent review", "get this verified"…

Trigger when the user requests a review of frontend files (e.g., .tsx, .ts, .js). Support both pending-change reviews and focused file reviews while applying the checklist rules.
fork-discipline
Audit and enforce the core/client boundary in multi-client projects. Detects where shared platform code is tangled with client-specific code, finds hardcoded client checks, config files that replace instead of merge, scattered client code, migration conflicts, and missing extension points. Produces a boundary map…

Run an independent code review using the OpenAI Codex CLI in headless mode. Gets a second opinion from a different model family (the current Codex models) on recent changes, a PR, a commit, or the whole app — covering bugs, regressions, security, data consistency, UX/state bugs, performance risks, and testing gaps.…
