LangBot Official AgentRunner Plugins

This repository contains the official external-service AgentRunner plugins for LangBot, migrated from the legacy built-in runners.

Overview

Each plugin directory is a standalone LangBot plugin that can be discovered, installed, and executed by the LangBot Plugin Runtime using AgentRunner Protocol v1.

Plugins

Plugin	Runner ID	Legacy Runner	Description
dify-agent	plugin:langbot/dify-agent/default	dify-service-api	Dify application integration
n8n-agent	plugin:langbot/n8n-agent/default	n8n-service-api	n8n workflow webhook integration
coze-agent	plugin:langbot/coze-agent/default	coze-api	Coze (扣子) bot integration
dashscope-agent	plugin:langbot/dashscope-agent/default	dashscope-app-api	Aliyun DashScope (百炼) integration
langflow-agent	plugin:langbot/langflow-agent/default	langflow-api	Langflow flow integration
tbox-agent	plugin:langbot/tbox-agent/default	tbox-app-api	Ant Tbox (百宝箱) integration

The official local-agent runner is maintained in the sibling langbot-local-agent repository because it has a separate release and test surface.

SDK Alignment

This repository consumes AgentRunner Protocol v1 through langbot-plugin-sdk. External-service runners mainly use:

• ctx.input for text and multimodal payloads
• ctx.params for workflow/business inputs
• ctx.state and ctx.conversation for external session IDs
• ctx.runtime.metadata.streaming_supported when the target service supports both streaming and non-streaming calls

ctx.prompt is exposed by the SDK for runners that call LangBot-hosted models directly, especially langbot-local-agent. These external-service runners should not reinterpret it as a replacement for each third-party platform's own prompt or app configuration.
