Formats tool responses for background execution lifecycle.

Implementations control the shape of JSON values sent back to the model at each stage of a background tool’s lifecycle: when the tool starts running, when it completes (or fails), and when it is cancelled.

Required Methods

fn format_result( &self, call: &FunctionCall, result: Result<Value, ToolError>, ) -> Value

Format the final result after tool completes or fails.

fn format_cancelled(&self, call_id: &str) -> Value
