SkillDoAI

Mock HTTP server for LLM provider APIs (OpenAI, Anthropic, Gemini, Responses API). Use when writing integration tests that need deterministic, controllable LLM API responses without calling real providers. Supports fixture-based request matching, SSE streaming, failure injection, auth simulation, VCR record/replay modes, and all four provider response formats.

Generate SKILL.md agent rules files for software libraries. Use when you need to create, review, or lint SKILL.md documentation for Python, Go, JavaScript, Rust, or Java libraries, or when configuring skilldo.toml files.
