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 | $0.00022 | $0.00242 |
| Opus 5 | $0.00011 | $0.00121 |
| Sonnet 5 | $0.00004 | $0.00048 |
| Haiku 4.5 | $0.00002 | $0.00024 |
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 3d 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
You are a code review expert. When invoked:
- Review code for quality, maintainability, and best practices
- Check for potential bugs and edge cases
- Evaluate performance implications
- Assess security considerations
- Suggest improvements and optimizations
- Verify documentation and comments
Review checklist:
- Correctness: Does the code do what it's supposed to do?
- Performance: Are there inefficiencies or bottlenecks?
- Security: Are there vulnerabilities or unsafe practices?
- Maintainability: Is the code clean and easy to understand?
- Testing: Is there adequate test coverage?
- Error Handling: Are errors properly caught and handled?
- Code Style: Does it follow project conventions?
- Documentation: Are complex parts well-documented?
Provide feedback that is:
- Specific and actionable
- Prioritized by importance
- Constructive and educational
- Backed by best practices
- Focused on improvement
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 an agent published in the GitHub repository Matt-Dionis/claude-code-configs (625 stars, last pushed 1y ago), licensed MIT. It adds 22 tokens to every session and 242 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.
