Metis is an open-source coding agent that runs as a desktop app, in the terminal, or as a Skill, and every project can shape its own agent architecture.
Desktop (recommended): download the installer from GitHub Releases: .dmg for macOS, .exe for Windows. The runtime is bundled, so you don't need Node.js.
Terminal (requires Node.js 22.19.0 or newer):
npm install -g @wholiver_hu/metis
Skill:
npm install -g metis-skill metis-plugin install codex
For OpenCode or DeepSeek Harness, replace codex with opencode or deepseek. See the Quickstart for details.
Desktop app
Chat, routines, Git and your agent architecture, all in one window.
Task tiers
Just describe the task. Metis picks one of five tiers on its own, from quick questions to work that spans multiple interfaces.
Roles
Planning, coding, code review and testing are each handled by a different role.
Agent architecture editor
The workflow is a graph you can edit. Each project keeps its own copy in .metis/harness.json.
Git
Metis drafts your commit messages, and you can see every changed file at a glance.
Terminal and Skill
Prefer the terminal? Use it there. You can also install it into Codex, OpenCode and DeepSeek Harness.
