## Core Features
- Inbound Feishu or Lark messages drive a DeepSeek Harness agent through the host agents service, and replies stream back into a live-updating Feishu message.
- Each chat identifier maps to a stable project directory under a configured workspace root, creating an isolated folder for every group or direct message conversation.
- Conversations use fixed per-chat session identifiers, allowing each chat session to resume after restarts instead of starting from an empty context.
- On first launch without credentials, the plugin can display a QR registration wizard that creates Feishu app credentials and stores them locally after scanning.
- Slash commands include /help, /new, /where, and /model for showing help, clearing chat context, showing the project directory, and showing or switching the model.

## Use Cases
- Teams can run separate coding projects in parallel by assigning one Feishu group to one workspace folder.
- Developers can interact with a dsh coding agent from Feishu direct messages when direct message handling is enabled.
- Users can combine conversational coding prompts with separate Lark CLI workflows for documents, sheets, messaging, or calendar operations.

## Technical Details
- The plugin connects to Feishu over a long-lived WebSocket, so no public IP address or callback URL is required.
- Credentials are read from inline plugin configuration, environment variables, or the local file written by the registration wizard.
- The package installs from source with pnpm, builds source into lib, and loads into dsh through a Cordis patch that injects agents, sessions, agentPresets, and agentDefaultModel.
- Runtime configuration includes tenant selection for feishu.cn or larksuite.com, model and provider overrides, workspace root, direct-message toggle, and group mention requirement.

## Notes
- The host requires a working DeepSeek Harness checkout, Node.js ^22.19.0 || >=24.0.0, and a DeepSeek API key.
- Feishu bot registration is per user, and the app secret cannot be shared without transferring control of the bot.
- Setting DSH_PERMISSION_MODE=danger-full-access disables agent approval prompts, which is required because Feishu users cannot approve local prompts.
