Model Context Hooks

React hooks for registering assistant-ui tools, data renderers, instructions, and model context providers.

API Reference

useAuiToolOverrides

Overrides toolkit entries for the current assistant scope.

This is intended for dynamic local-state tools whose model-facing contract is declared in a "use generative" toolkit file with execute: stubTool(), but whose actual executor must close over React state in the mounted component. Keep the override keys stable after mount; dynamic key addition/removal is not currently observed. Overrides are registered at priority 1000, above toolkit defaults. Only one mounted override provider may define a given tool name at a time.
