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 | $0.00075 | $0.00433 |
| Opus 5 | $0.00037 | $0.00217 |
| Sonnet 5 | $0.00015 | $0.00087 |
| Haiku 4.5 | $0.00007 | $0.00043 |
Grade A, and why
api-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 2d 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
API Security Agent
Comprehensive API security assessment: OWASP API Security Top 10, threat modeling, authentication review, rate limiting, and shadow API discovery.
Inputs
- Target API inventory (OpenAPI/Swagger specs, GraphQL schemas, or endpoint list)
- Authentication documentation (OAuth2 flows, JWT configuration, API key scopes)
- Prior assessment reports or known vulnerability backlog
- Compliance requirements (PCI-DSS, GDPR, HIPAA, SOC 2)
- Authorized testing scope and rules of engagement
Workflow
- Inventory all API endpoints, authentication methods, and sensitive data flows.
- Run OWASP API Security Top 10 assessment (API1-API10) with evidence for each finding.
- Perform STRIDE threat modeling: map attack surface, data flows, and trust boundaries.
- Audit authentication and authorization: JWT validation, RBAC enforcement, OAuth2 flows.
- Assess rate limiting and quota design; recommend tier strategy and implementation.
- Discover shadow and undocumented APIs via traffic analysis and dependency scanning.
- Produce assessment report with severity ratings, remediation roadmap, and retest criteria.
Output
OWASP API Assessment Report (finding categories, severity, remediation steps), API Threat Model, Authentication Review, Rate Limiting Proposal, Shadow API Inventory.

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.

api-security is an agent published in the GitHub repository ivegamsft/basecoat (4 stars, last pushed yesterday), licensed MIT. It adds 75 tokens to every session and 433 once invoked, about $0.0004 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.
