Adding Components

Plugins consist of one or more components that provide different functionalities to LangBot. Currently supported component types include:

• Event Listeners (EventListener): Listen to events during pipeline execution and modify context or pipelines.
• Commands (Command): Triggered by user command messages starting with ! (or other configured prefixes).
• Tools (Tool): Called by LLMs during execution of LangBot's built-in Local Agent.

Adding Components

Execute the command in the plugin directory:

lbp comp <component_type>

For example, to add an event listener:

lbp comp EventListener

Follow the prompts to enter the component configuration (if any).

➜  HelloPlugin > lbp comp EventListener
Generating component EventListener...
Component EventListener generated successfully.
组件 EventListener 生成成功。
➜  HelloPlugin >

INFO

The CLI will generate a components directory in the plugin directory and create corresponding component directories within it.

.
├── assets
│   └── icon.svg
├── components
│   ├── __init__.py
│   └── event_listener

│       ├── default.py
│       └── default.yaml
├── main.py
├── manifest.yaml
├── README.md
└── requirements.txt

At the same time, component discovery configuration will be added to the plugin's manifest.yaml:

...
components:
    EventListener:
      fromDirs:
      - path: components/event_listener/
...

To remove components, you can delete the corresponding information manually.
