Tool Input Lifecycle Hooks
Explore tool input lifecycle hooks: onInputStart, onInputDelta, and onInputAvailable. See how to track tool input generation in real-time during streaming.
Preliminary Tool Results
Return preliminary tool results using async iterables. Stream status updates during tool execution before the final result is available.
Tool API Context
Pass arbitrary context from generateText/streamText to tool execution via experimental_context. Access context in tool execute functions for dynamic behavior.
Dynamic Tool
Create dynamic tools with runtime-generated schemas using dynamicTool. Demonstrates unit conversion tools where schema adapts based on conversion type (temperature, length, weight, currency) and supports dynamic model selection.
