api-anything

Transform an OpenAPI / Swagger specification into a production-grade, agent-first CLI.

Governing contract

Every CLI produced by this skill must conform to the CLI-MANIFEST — the normative design contract for agent-first CLIs. The full manifest is embedded in references/cli-manifest-contract.md. Read it before generating any CLI code.

The manifest defines 23 principles across 5 parts (Foundations, Read & Discover, Safe Mutation, Transactional Workflows, Multi-Agent Coordination). It covers the output envelope, error taxonomy, exit codes, read/write separation, guide command, LLM=true handling, mutation safety, and transactional workflow patterns that the generated CLI must implement.

When to use this skill

• User provides an OpenAPI 3.x or Swagger 2.0 spec and wants a CLI built from it
• User wants an agent-usable CLI wrapper around a REST API
• User needs enterprise auth profiles (OAuth, OIDC, mTLS, API keys) wired into a CLI
• User wants normalized resource commands rather than raw HTTP path mirroring
