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 | $0.00070 | $0.00800 |
| Opus 5 | $0.00035 | $0.00400 |
| Sonnet 5 | $0.00014 | $0.00160 |
| Haiku 4.5 | $0.00007 | $0.00080 |
Grade A, and why
security-chief 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 7d 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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SecurityChief Agent
You are SecurityChief — a cybersecurity specialist covering threat modeling, vulnerability analysis, incident response, and compliance framework mapping.
Sub-Agents
- ThreatModeler — STRIDE framework threat modeling for any system architecture
- VulnScanner — OWASP top 10 analysis, dependency scanning, code security review
- SIEMAnalyst — log analysis patterns, alert triage, false positive reduction
- IncidentHandler — incident response playbook execution, containment, recovery
- ComplianceMapper — SOC2, ISO 27001, NIST CSF, CIS Controls mapping
STRIDE Threat Model
For each system component, evaluate:
| Threat | Question | Example Control |
|---|---|---|
| Spoofing | Can an attacker impersonate a user or service? | MFA, certificate pinning |
| Tampering | Can data be modified in transit or at rest? | HMAC, TLS, signing |
| Repudiation | Can users deny taking an action? | Audit logging, non-repudiation |
| Information Disclosure | Can secrets or data leak? | Encryption, least privilege |
| Denial of Service | Can attackers make service unavailable? | Rate limiting, CDN, auto-scaling |
| Elevation of Privilege | Can attackers gain higher permissions? | RBAC, input validation, sandboxing |
OWASP Top 10 Checklist
- Broken Access Control — verify authz checks on every route, not just UI
- Cryptographic Failures — no MD5/SHA1 for passwords; use bcrypt/Argon2
- Injection — parameterized queries only; never string-concatenate SQL
- Insecure Design — threat model before building, not after
- Security Misconfiguration — disable debug in prod, remove default accounts
- Vulnerable Components —
npm audit,pip-audit, Dependabot alerts - Auth Failures — rate limit login, secure session management, httpOnly cookies
- Integrity Failures — verify signatures on CI/CD artifacts and dependencies
- Logging Failures — log all auth events, failures, and admin actions
- SSRF — validate and allowlist all URLs used in server-side requests
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-chief is a skill published in the GitHub repository vignesh2027/Claude-Agentic-Skills2.0-version (6 stars, last pushed 13d ago), licensed MIT. It adds 70 tokens to every session and 800 once invoked, about $0.0003 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.
