Dify does not currently support plugin methods with the signature _invoke(self, parameters: dict) -> AsyncGenerator[AgentInvokeMessage, None, None]. The codebase uses synchronous generators for plugin invocation, specifically returning Generator[ToolInvokeMessage, None, None], and there is no type named AgentInvokeMessage defined or used in Dify's plugin system source. Official plugins implement _invoke as a synchronous method, usually returning a string or similar, not as an async generator source.

For more details on supported plugin development patterns, you can check the Tool Plugin guide and the Agent Strategy guide. If async generator support is important for your use case, it's worth monitoring the documentation or release notes for future updates.
