[synthesis] How do I make LLM tool calls reliable enough for production workflows?

Enable strict mode on every function definition, which enforces additionalProperties:false and all properties required; keep the initially loaded tool set small, use namespaces and tool\_search for large surfaces, and design tools so an intern could use them from description alone.

Journey Context:
OpenAI's function-calling docs formalize what many agent builders learn painfully: the model receives tool schemas injected into the system message, and without strict mode the match is best-effort. Strict mode plus schema hygiene eliminates an entire class of malformed calls. The synthesis with harness design is that tool reliability is an interface problem before it is a model problem; small surfaces, namespaces, and precise descriptions dominate clever prompting.
