Module tool_schema 

Tool-catalog renderer — Phase 2 of action-grain unification (2026-04-20).

Renders Tool grains with kind = Definition into the wire format of a target LLM provider (OpenAI, Anthropic, Gemini, MCP, Hermes, Llama 3.1, Markdown, SML). Every adapter accepts a Phase-1-validated definition and produces output that is legal for its target provider by construction.

Adapter outputs are deterministic — same input, same bytes — so CAL template rendering is stable across replicas.

See docs/facts/tool-formats.md for output shape examples.
