api-documentation

api-documentation is a skill for Claude Code from sendralt/agentic-awesome-skills. It costs 23 tokens per session (848 once invoked), scanned A, a copy of api-documentation, MIT.

A workflow for creating and maintaining API documentation, including OpenAPI specifications, developer guides, examples, and interactive documentation. OpenAPI is a standard machine-readable description of an API.

In plain words
What is it for?
Use it to inventory an API, create its OpenAPI description, write developer instructions, and set up documentation for users or integrators.
Why use it?
It breaks documentation work into discovery, specification, and guide-writing stages, making missing endpoints, authentication, errors, and examples easier to identify.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

api-documentation 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 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.
