When adding Usage Examples to docs/skills/<skill>.md, include subsections for Gemini, Claude, OpenAI, DeepSeek, and Ollama (prompt mode). Each block should be runnable: imports, load_env_file(), load_skill, adapter, system instructions, sample user message, and execute on tool call.
Link to agent_loops.md and README.md. List skill-specific env vars in an Environment table; link to api_keys.md for setup.
Do not duplicate the full API keys guide on skill pages.
