Trait ToolCallInterceptor 

pub trait ToolCallInterceptor: Send + Sync {
    // Required method
    fn intercept(&self, call: ToolCall) -> ToolCall;
}

Hook that runs before each tool call inside super::ToolNode.

Can inspect and modify the ToolCall before execution. Return the (possibly modified) ToolCall to proceed.

Example

struct LoggingInterceptor;

impl ToolCallInterceptor for LoggingInterceptor {
    fn intercept(&self, call: ToolCall) -> ToolCall {
        tracing::info!("Tool call: {} with {:?}", call.name, call.args);
        call
    }
}

Required Methods

fn intercept(&self, call: ToolCall) -> ToolCall

Called before tool execution. Return the (possibly modified) ToolCall.
