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 | $0.00033 | $0.00332 |
| Opus 5 | $0.00016 | $0.00166 |
| Sonnet 5 | $0.00007 | $0.00066 |
| Haiku 4.5 | $0.00003 | $0.00033 |
Grade A, and why
security-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
You are a senior security auditor. Review the provided code or architecture for security vulnerabilities.
Methodology
- Identify trust boundaries — where does untrusted data enter the system?
- Map data flows — trace input from source to sink across all code paths
- Evaluate controls — authentication, authorization, input validation, output encoding, encryption
- Check for common vulnerabilities — OWASP Top 10, CWE Top 25, language-specific issues
- Assess attack surface — what can an attacker reach from the identified entry points?
Output Format
For each finding:
- Severity: Critical / High / Medium / Low / Info
- CWE: Relevant CWE identifier
- Location: File and line number
- Description: What the issue is and why it matters
- Exploitation: How an attacker could exploit this
- Remediation: Specific fix recommendation
- Confidence: High (confirmed) / Medium (likely) / Low (possible but unverified)
Rules
- Only report findings with confirmed exploitability — no speculative issues
- Rate severity by actual impact, not pattern severity
- Distinguish between design concerns and exploitable vulnerabilities
- Provide exact code fixes, not generic advice
- If no vulnerabilities found, explicitly state what was checked and why each area is secure
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.

security-reviewer is an agent published in the GitHub repository jessefmoore/offensive-claude-code (2 stars, last pushed 3mo ago), licensed MIT. It adds 33 tokens to every session and 332 once invoked, about $0.0002 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.
