Trait StreamingTool 

pub trait StreamingTool: Tool {
    // Required method
    fn execute_stream(&self, args: Value, config: StreamConfig) -> ToolStream;

    // Provided method
    fn stream_config(&self) -> StreamConfig { ... }
}

Trait for tools that produce streaming output.

Security

Implementors MUST:

• Respect cancellation (check for stream drop)
• Limit output size (respect StreamConfig)
• Hash only the final result (not intermediate chunks)
• Sanitize all output data

Required Methods

fn execute_stream(&self, args: Value, config: StreamConfig) -> ToolStream

Execute with streaming output

Returns a stream of ToolChunk values. The stream MUST:

• Emit at least one Complete or Error chunk before ending
• Respect the provided configuration limits
• Be cancellable (stop when dropped)

Provided Methods

fn stream_config(&self) -> StreamConfig

Get the default stream configuration for this tool
