Function Calling Consultation — Reliable LLM Tool Use

I will assess your LLM application and deliver a written function calling design consultation — covering function schema design for reliable tool selection, the right function granularity for your use case, parallel vs. sequential function calling strategy, and error handling design for function execution failures. Function calling design mistakes made before implementation produce systems where the LLM selects the wrong function for ambiguous cases, calls functions with incorrectly typed parameters, or fails to recover from function execution errors — all problems that careful schema design and error handling prevent.

The report covers your use case and tool requirements, function schema design principles for reliable selection, granularity recommendation (fine-grained vs. coarse-grained functions), parallel calling strategy, error handling design, and an implementation approach for your LLM provider.
