This repository is a native plugin built exclusively for DeepSeek Harness (DSH) that enables collaborative workflows between human users and multiple independent AI agents in a single persistent session. Each AI agent has its own custom identity, model configuration, and separate session, and can leverage tools and skills from the active DSH agent preset to complete assigned tasks. To install the prebuilt version from GitHub, you just run the DSH manage plugin command pointing to this repository, then restart DSH to load the plugin. If you prefer to build from source, you can clone the repo, run npm install and npm run build, then add the local directory to your DSH web profile.

The typical workflow starts with configuring your model providers in DSH system settings, then creating AI members in the plugin’s user center with custom names, avatars, personality prompts, and assigned models. After that, you can create one-on-one private chats, multi-AI group chats, or choose from pre-set meeting templates like AI court, code review, or roundtable discussion. For complex work, you can split tasks into a dedicated task board, compare multiple candidate solutions on a structured decision board, and store final outputs in a results library for human review and approval. This plugin is ideal for users that need to leverage multiple AI models to work through complex problems and make structured decisions.

This plugin is released under the open source MIT license, and requires Node.js 22 or higher if you build it from source. All conversation and meeting data is stored locally on your machine in the DSH home directory, and the plugin never reads or stores your API keys, which are pulled directly from DSH system configuration. Each AI agent can be assigned custom permissions ranging from read-only to full workspace access, and high-risk actions from restricted agents require explicit human approval before execution. Configurable rate limiting and request queueing help reduce the chance of hitting provider rate limits when multiple agents share the same provider account.
