Trait Tool 

pub trait Tool: Send + Sync {
    // Required methods
    fn name(&self) -> &str;
    fn description(&self) -> &str;
    fn input_schema(&self) -> Value;
    fn execute(&self, input: Value) -> ToolResult<'_>;
}

A tool that can be invoked by an LLM.

Tools are contributed by plugins via Plugin::tools() and registered with the host’s tool registry. The LLM calls tools by name.
