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 | $0.00026 | $0.02230 |
| Opus 5 | $0.00013 | $0.01115 |
| Sonnet 5 | $0.00005 | $0.00446 |
| Haiku 4.5 | $0.00003 | $0.00223 |
Grade A, and why
security-testing 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.
How it starts
The opening of the file, as written. The whole thing — 312 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Security Testing
<default_to_action> When testing security or conducting audits:
- TEST OWASP Top 10 vulnerabilities systematically
- VALIDATE authentication and authorization on every endpoint
- SCAN dependencies for known vulnerabilities (npm audit)
- CHECK for injection attacks (SQL, XSS, command)
- VERIFY secrets aren't exposed in code/logs
Quick Security Checks:
- Access control → Test horizontal/vertical privilege escalation
- Crypto → Verify password hashing, HTTPS, no sensitive data exposed
- Injection → Test SQL injection, XSS, command injection
- Auth → Test weak passwords, session fixation, MFA enforcement
- Config → Check error messages don't leak info
Critical Success Factors:
- Think like an attacker, build like a defender
- Security is built in, not added at the end
- Test continuously in CI/CD, not just before release </default_to_action>
Quick Reference Card
When to Use
- Security audits and penetration testing
- Testing authentication/authorization
- Validating input sanitization
- Reviewing security configuration
OWASP Top 10 (2021)
| # | Vulnerability | Key Test |
|---|---|---|
| 1 | Broken Access Control | User A accessing User B's data |
| 2 | Cryptographic Failures | Plaintext passwords, HTTP |
| 3 | Injection | SQL/XSS/command injection |
| 4 | Insecure Design | Rate limiting, session timeout |
| 5 | Security Misconfiguration | Verbose errors, exposed /admin |
| 6 | Vulnerable Components | npm audit, outdated packages |
| 7 | Auth Failures | Weak passwords, no MFA |
| 8 | Integrity Failures | Unsigned updates, malware |
| 9 | Logging Failures | No audit trail for breaches |
| 10 | SSRF | Server fetching internal URLs |
Tools
| Type | Tool | Purpose |
|---|---|---|
| SAST | SonarQube, Semgrep | Static code analysis |
| DAST | OWASP ZAP, Burp | Dynamic scanning |
| Deps | npm audit, Snyk | Dependency vulnerabilities |
| Secrets | git-secrets, TruffleHog | Secret scanning |

What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-testing is a skill published in the GitHub repository summarybotng/summarybot-ng (2 stars, last pushed 2mo ago), licensed MIT. It adds 26 tokens to every session and 2,230 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 2026-09-03.
