}

Trait for tool definitions that can be wrapped into AgentTool.

Required Methods

fn tool_name(&self) -> &str

Returns the tool name used in LLM function-calling.

fn tool_label(&self) -> &str

Returns a human-readable label for UI display.

fn tool_description(&self) -> &str

Returns the tool description sent to the LLM.

fn tool_parameters(&self) -> Value

Returns the JSON schema for the tool’s parameters.

fn tool_execute( &self, tool_call_id: &str, params: Value, signal: Option<Receiver<()>>, ) -> Pin<Box<dyn Future<Output = Result<AgentToolResult, ToolError>> + Send>>

Executes the tool with the given call ID, parameters, and optional cancellation signal.

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
