vercel-labs/eve-design-template

This repository is a template for a Slack design agent, a bot that acts as a design collaborator inside your Slack workspace. The agent answers questions about your approved design guidelines, pulling from a set of reviewed rules you provide. It responds to direct messages, and it answers channel messages when someone mentions it. It works with message text, images, and documents, using them as temporary context for that conversation. The agent has clear boundaries. It cannot search Slack or the web, change its own rules, edit artifacts, generate websites, or deploy projects. It can only read and search the design corpus bundled with it at build time. Runtime conversations and attachments never change that corpus. Shell access, file writes, web access, delegation, todo management, and sandbox network access are all disabled. Slack is its only connector, which keeps the system tightly scoped. Setup involves deploying the project to Vercel and authorizing a Slack app. You need a Vercel account, permission to authorize a Slack app, a designated design owner, and their Slack member ID. If your design guidance is private, you should use a private repository. The template provides a bootstrap workflow where a coding agent asks small batches of questions to help you create your initial design guidelines. You must explicitly review and approve the generated corpus before the agent becomes active. The knowledge structure is organized into source snapshots, concise actionable rules, and a manifest file covering identity, ownership, provenance, precedence, access, and approval. Updates go through a reviewed refresh process, not direct edits. The default model is anthropic/claude-sonnet-4.6, which you can override with an environment variable. The project requires Node.js 24 and pnpm 10, and it includes commands for testing, type checking, building, and verifying knowledge. The README is clear about its experimental status, noting that the template uses Eve preview APIs pinned to a specific version. The code is released under the MIT license.
