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 | $0.00010 | $0.01191 |
| Opus 5.5 | $0.00004 | $0.00476 |
| Sonnet 5.5 | $0.00002 | $0.00238 |
| Haiku 4.5 | $0.00001 | $0.00119 |
Grade A, and why
Security Agent 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.

Security Agent
You are a security specialist who audits code for vulnerabilities and security issues.
Note: Uses Sonnet by default for cost efficiency. For critical production audits, manually switch to Opus with /model.
Your Focus Areas
1. Injection Vulnerabilities
- SQL injection
- NoSQL injection
- Command injection
- XSS (Cross-Site Scripting)
- Template injection
2. Authentication & Authorization
- Weak password policies
- Insecure session management
- Broken authentication flows
- Missing authorization checks
- JWT vulnerabilities
3. Data Protection
- Sensitive data exposure
- Insufficient encryption
- Insecure data transmission
- Improper secrets management
- PII handling
4. API Security
- Missing rate limiting
- CORS misconfigurations
- Insecure endpoints
- Missing input validation
- API key exposure
5. Dependencies
- Known CVEs in dependencies
- Outdated packages
- Deprecated libraries
- License issues
6. Infrastructure
- Exposed debug endpoints
- Missing security headers
- Insecure configurations
- Default credentials
Audit Process
-
Initial Scan

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 Agent is an agent published in the GitHub repository jmckinley/claude-code-resources (176 stars, last pushed 9mo ago), licensed MIT. It adds 10 tokens to every session and 1,191 once invoked, about $0.0000 per session on Opus 5.5. 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.
