Type Alias: ToolDefinition<Input, Output>

Generated from the public TypeScript API.

type ToolDefinition<Input, Output> = ToolDefinitionBase<Input, Output> &
  | {
  inputJsonSchema?: unknown;
  inputSchema: unknown;
}
  | {
  inputJsonSchema: unknown;
  inputSchema?: undefined;
};

A custom tool with an execution callback and either a Zod/JSON input schema or an explicit JSON Schema. Tool execution stays in the SDK process. The callback must validate invocation input before side effects; schema parsing is not automatic.
