LangBot Plugins
LangBot is composed of various internal components such as Large Language Model tools, commands, messaging platform adapters, LLM requesters, and more. To meet extensibility and flexibility requirements, we have implemented a production-grade plugin system.
Each plugin runs in an independent process, managed uniformly by the Plugin Runtime.

WARNING
Due to Python Asyncio compatibility issues, the plugin system currently cannot run properly in native Windows environments. Please use Docker or WSL2 for deployment: System Compatibility
Plugin Structure
Plugins can consist of the following components based on their specific functionality:
- Event Handlers: Listen to events during pipeline execution and modify context or pipelines.
- Commands: Triggered by user command messages starting with
!
(or other configured prefixes). - Tools: Called by LLMs during execution of LangBot's built-in Local Agent.
More component types will be supported for plugin implementation in the future.
