https://github.com/user-attachments/assets/8f1d8567-f9fb-41bb-a6a0-b2ff98a13f25 ## Multiplayer coding agents This demo shows you how to implement a multiplayer coding agent tool, with [Liveblocks](https://liveblocks.io/). - **Shared chats**: Each chat is a multiplayer Liveblocks Feed. - **Queue and merge**: Messages posted while the agent is busy are queued and handled as a follow-up. - **Jev triage**: TypeSafe AI chooses whether a response to each message is needed—a coding agent, or just a regular AI. - **Quick answers**: Questions are answered with read-only tools to browse the repository. - **Coding sessions**: A Cursor agent commits, pushes, and opens a pull request of requested changes. - **Changes and PR tabs**: Side panel shows the PR's diff rendered with `@pierre/diffs`. - **Multiplayer documents**: Write Markdown documents as well as code, and edit them in a multiplayer markdown editor. - **Skills**: Place skils into the `/skills` folder, load them with `/`. - **Notifications**: Participants receieve a notification when the agent has completed coding. - **Access control**: Members of your GitHub organization, and users on the allow-list, can talk to the agent. ### Set up - Install all dependencies with `npm install` - Create an account on [liveblocks.io](https://liveblocks.io/dashboard) - Copy your **secret** key from the [dashboard](https://liveblocks.io/dashboard/apikeys) - Create an `.env.local` file at the root (see `.env.example`) and add your **secret** key as the `LIVEBLOCKS_SECRET_KEY` environment variable - Create a Cursor API key in the [Cursor dashboard](https://cursor.com/dashboard) and add it as `CURSOR_API_KEY` (use a team **service account** key so runs aren't tied to one person) - In the Cursor dashboard, connect GitHub under **Integrations** and grant the Cursor GitHub App access to the repositories your team will work on - Create a [GitHub OAuth App](https://github.com/settings/developers) with the callback URL `http://localhost:3000/api/auth/callback/github`, and add its client id and secret as `AUTH_GITHUB_ID` and `AUTH_GITHUB_SECRET` - Set `AUTH_SECRET` to a random string (`openssl rand -base64 32`) - Set `GITHUB_ALLOWED_ORG` to your GitHub organization, or list logins in `GITHUB_ALLOWED_USERS`; leave both empty locally to let anyone who signs in take part - Create an account on [vercel.com](https://vercel.com) - Copy your **AI gateway key** from the [dashboard](https://vercel.com/ai-gateway) into the `AI_GATEWAY_API_KEY` environment variable (this enables Jev triage and quick answers; without it, every message goes to the coding agent) - Optionally set `GITHUB_TOKEN` to a read-only fine-grained token so private repositories' branches and files can be read, `CURSOR_MODEL` to change the default model, or `NEXT_PUBLIC_LOCKED_REPO` to pin every chat to one repository - Run `npm run dev` and go to [http://localhost:3000](http://localhost:3000)
