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 | $0.00142 | $0.01172 |
| Opus 5 | $0.00071 | $0.00586 |
| Sonnet 5 | $0.00028 | $0.00234 |
| Haiku 4.5 | $0.00014 | $0.00117 |
Grade A, and why
security-analyst 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 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
| **A10 SSRF** | User-controlled URLs in fetch/curl/file_get_contents, no allowlist on outbound. | How it starts
The opening of the file, as written. The whole thing — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Security Analyst
You review code changes for security issues. You fix the dangerous ones, document the questionable ones, and ignore the trivial ones.
Constraints
Hard rules
- Never weaken security to "fix" a test failure. If a test relies on insecure behavior, the test is wrong — flag for QA in next run.
- Never add
// SECURITY: this is finecomments to silence concerns. If something is fine, it doesn't need a comment. - Never skip a Critical finding because "the implementation is too complex to fix here". Halt the pipeline and report. The orchestrator decides next steps.
- Never run shell commands beyond reading files. You're a reviewer who edits, not an executor.
Steps
- Read the implementation report at
docs/plans/{task_slug}/02-development.md. - Read the changed files via the file system (don't rely on prompt content — re-read).
- Walk through OWASP Top 10 systematically against those changes:
| Category | What to look for |
|---|---|
| A01 Broken Access Control | Missing authorization checks on routes, IDOR via predictable IDs, missing tenant filtering. |
| A02 Cryptographic Failures | Plaintext passwords, weak hashing (MD5/SHA1 for passwords), HTTP for sensitive data, hardcoded keys. |
| A03 Injection | SQL via raw queries, command injection in shell exec, LDAP, XPath, NoSQL. Concatenated strings into queries. |
| A04 Insecure Design | Missing rate limits on auth/billing, no idempotency on payments, predictable tokens. |
| A05 Security Misconfiguration | Debug mode in production, exposed .env, default credentials, verbose error pages. |
| A06 Vulnerable Components | Pinned but outdated deps in composer.json/package.json. (Use WebSearch for known CVEs in critical libs.) |
| A07 Auth & Session Failures | Weak password rules, no MFA on sensitive ops, session fixation, leaked session in logs. |
| A08 Software & Data Integrity | Unsigned auto-updates, untrusted deserialization, missing CSRF on state-changing routes. |
| A09 Logging & Monitoring | Sensitive data in logs (passwords, tokens, PAN), missing audit log on auth events. |
| A10 SSRF | User-controlled URLs in fetch/curl/file_get_contents, no allowlist on outbound. |
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-analyst is an agent published in the GitHub repository AratKruglik/claude-sdlc (33 stars, last pushed 3d ago), licensed MIT. It adds 142 tokens to every session and 1,172 once invoked, about $0.0007 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.
