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 | $0.00071 | $0.02602 |
| Opus 5 | $0.00036 | $0.01301 |
| Sonnet 5 | $0.00014 | $0.00520 |
| Haiku 4.5 | $0.00007 | $0.00260 |
Grade A, and why
security-misconfiguration scanned grade A with 1 finding 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 4d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Security Misconfiguration (OWASP A06)
Detect and fix insecure default configurations, missing security headers, exposed debug info, and cloud misconfigurations.
When to Use
- Configuring web servers (Nginx, Apache)
- Setting up cloud resources (AWS, GCP, Azure)
- Deploying applications to production
- Reviewing security headers
- Auditing CORS configuration
- Checking for exposed sensitive endpoints
Common Misconfigurations
| Issue | Risk | Impact |
|---|---|---|
| Debug mode enabled | HIGH | Information disclosure |
| Default credentials | CRITICAL | Full system compromise |
| Missing security headers | MEDIUM | XSS, clickjacking |
| Directory listing | MEDIUM | Information disclosure |
| Verbose error messages | MEDIUM | Attack surface exposure |
| Open cloud storage | CRITICAL | Data breach |
| Unnecessary services | MEDIUM | Increased attack surface |
Detection Patterns
Debug Mode in Production
// VULNERABLE - Debug mode enabled
app.set('env', 'development');
DEBUG=* node app.js
// VULNERABLE - Stack traces in errors
app.use((err, req, res, next) => {
res.status(500).json({
error: err.message,
stack: err.stack // Never in production!
});
});
// VULNERABLE - Source maps in production
// webpack.config.js
devtool: 'source-map' // Exposes source code
Missing Security Headers
// VULNERABLE - No security headers set
app.get('/', (req, res) => {
res.send('<html>...</html>');
});
// Check current headers
curl -I https://example.com
// Missing: X-Frame-Options, CSP, etc.
CORS Misconfiguration
// VULNERABLE - Allow all origins
app.use(cors({
origin: '*',
credentials: true // Dangerous with wildcard!
}));
// VULNERABLE - Reflecting origin
app.use(cors({
origin: req.headers.origin, // Reflects any origin
credentials: true
}));
Cloud Storage Misconfiguration
// VULNERABLE - Public S3 bucket policy

}]
}
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-misconfiguration is a skill published in the GitHub repository latestaiagents/agent-skills (5 stars, last pushed 4mo ago), licensed MIT. It adds 71 tokens to every session and 2,602 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
