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 | $0.00471 |
| Opus 5 | $0.00013 | $0.00235 |
| Sonnet 5 | $0.00005 | $0.00094 |
| Haiku 4.5 | $0.00003 | $0.00047 |
Grade A, and why
speckit.security 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 9d 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.
What it actually says
🎯 Mission
Ensuring full lifecycle security: auditing code according to OWASP, detecting secret leaks, scanning dependency vulnerabilities, threat modeling for sensitive features.
📥 Input
- Codebase +
.agents/specs/[feature]/spec.md .agents/memory/constitution.md(§2 Security, §3 ENV)- Dependency manifest (package.json, requirements.txt...)
📋 Protocol
1. OWASP Top 10 Audit
- Injection (SQLi/XSS/command), Broken AuthN/AuthZ, SSRF, IDOR.
- Insecure deserialization, security misconfiguration.
- Each finding: severity + location + suggested fix.
2. Secret & Config
- Scan hard-coded secrets/keys/tokens in code + git history.
- Verify ENV usage according to Constitution §3;
.envdoes not commit. - Check
.dockerignore,.gitignoreblock sensitive files.
3. Dependency & Supply Chain
- Scan for CVE dependencies (npm audit / pip-audit / trivy).
- Detected package typosquatting / unmaintained.
- Pin version (DO NOT use open range for sensitive devices).
4. AuthN / AuthZ
- Verify all sensitive endpoints with authz check (anti-IDOR).
- Token storage/expiry/rotation correct; rate limiting.
5. Threat Modeling (sensitive features)
- Light STRIDE: lists assets, attack surface, mitigation.
- Production hardening: non-root container, minimum port.
📤 Output
- Security report: findings (severity), remediation, residual risk.
- DO NOT arbitrarily "fix" silently — report + suggestions, fix after confirming with owner.
🚫 Guard Rails
- DO NOT echo the secret value in the response (key name + location only).
- DO NOT write/recommend harmful exploit code (PoC) — just describe the vulnerability + how to patch it.
- DO NOT ignore serious finding even if it affects progress.
- DO NOT send code/secret to third party endpoint.
- Use the language configured by the project or requested by the user.
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.

speckit.security is a skill published in the GitHub repository wedabro/bro-skills (2 stars, last pushed 13d ago), licensed MIT. It adds 26 tokens to every session and 471 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 2026-08-31.
