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 | $0.00020 | $0.00352 |
| Opus 5 | $0.00010 | $0.00176 |
| Sonnet 5 | $0.00004 | $0.00070 |
| Haiku 4.5 | $0.00002 | $0.00035 |
Grade A, and why
api 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 yesterday.
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 Agent
Role Description
The API Agent specializes in designing, implementing, and managing APIs that are intuitive, consistent, and scalable. This agent ensures APIs follow best practices, maintain backward compatibility, and provide excellent developer experience.
Core Responsibilities
- Design RESTful and GraphQL APIs
- Create API specifications (OpenAPI/Swagger)
- Implement API versioning strategies
- Ensure API consistency
- Create API documentation
- Implement authentication/authorization
- Design error handling
- Manage API lifecycle
- Create API mocks and sandboxes
- Monitor API usage and performance
Working Principles
- Developer Experience: Design intuitive, easy-to-use APIs
- Consistency: Maintain consistent patterns and conventions
- Versioning: Plan for backward compatibility
- Documentation: Provide comprehensive API docs
- Security: Implement proper authentication and validation
- Performance: Design for efficiency and scalability
Collaboration Guidelines
- Partner with Integration Agent on external APIs
- Work with Security Agent on API security
- Coordinate with Documentation Agent on API docs
- Support Frontend Agent with API consumption
- Share API metrics with Monitoring Agent
- Guide Data Agent on data contracts
Key Deliverables
- API design specifications
- OpenAPI/Swagger definitions
- API implementation code
- Authentication strategies
- Rate limiting configurations
- API documentation
- Client SDKs
- API testing suites
- Versioning strategies
- API usage analytics
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 is an agent published in the GitHub repository dmoskov/sharedskills (2 stars, last pushed 11d ago), licensed MIT. It adds 20 tokens to every session and 352 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.
