Toolkits & Structured Tool Inputs
Bundle related tools into reusable toolkits and define structured, typed arguments with schemas so agents call your tools reliably with the right parameters.
Beyond Single Tools
Real integrations rarely need just one function. A database integration needs list-tables, run-query, and describe-schema together.
A toolkit groups related tools so an agent gets a coherent capability in one bundle.
The Single-String Limitation
A basic tool takes one string input. But many actions need multiple typed arguments — a date range, a user id, a limit.
Structured tools let the agent pass several validated parameters instead of cramming them into one string.
