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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00022 | $0.00249 |
| Opus 5 | $0.00011 | $0.00125 |
| Sonnet 5 | $0.00004 | $0.00050 |
| Haiku 4.5 | $0.00002 | $0.00025 |
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 5d 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 Skill
A practical example skill for code review tasks.
When to Use
Activate this skill when the user:
- Asks for a code review
- Wants to check code for bugs
- Requests feedback on a pull request
- Needs code quality improvements
Review Checklist
When reviewing code, check for:
- Correctness - Does the code do what it's supposed to?
- Security - Are there any vulnerabilities?
- Performance - Any obvious inefficiencies?
- Readability - Is the code clear and well-structured?
- Edge Cases - Are boundary conditions handled?
Response Format
Structure your review as:
## Summary
Brief overview of the code quality
## Issues Found
- Issue 1: [description] (severity: high/medium/low)
- Issue 2: [description] (severity: high/medium/low)
## Suggestions
- Improvement 1
- Improvement 2
## Verdict
APPROVE / REQUEST CHANGES / NEEDS DISCUSSION
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 nicobailon/skills-hook (2 stars, last pushed 9mo ago), licensed MIT. It adds 22 tokens to every session and 249 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 2026-08-31.
