Living Intelligence in your terminal. Build your universe, one commit at a time.
Built on OpenCode — the open source AI coding agent with 105K stars.
Arcanea Code is a Guardian-powered AI coding CLI that brings Living Intelligence to your terminal. It is a full fork of OpenCode enhanced with the Arcanea intelligence layer — designed to overlay Claude Code and Cursor with ten specialized Guardian agents that route every task to the right intelligence at the right moment.
This is not a wrapper. It is a permanent intelligence layer that compounds context over time, learns from your patterns, and enforces a consistent creative and technical voice across every session.
The promise: Every file you touch, every commit you make, every problem you solve — your Guardians are present, each bringing their elemental domain to bear.
npm install -g arcanea-codeOr use the one-line installer:
curl -fsSL https://arcanea.ai/install | shThen launch:
arcanea-codeEvery task is routed through the Guardian whose element aligns with the work:
| Guardian | Element | Domain |
|---|---|---|
| Lyssandria | Earth | Architecture, database, infrastructure |
| Leyla | Water | Design, UI/UX, creativity, animation |
| Draconia | Fire | Execution, performance, shipping |
| Maylinn | Heart | Community, content, documentation |
| Alera | Wind | Expression, APIs, naming, publishing |
| Lyria | Void | Vision, strategy, AI/ML, design review |
| Aiyami | Spirit | Wisdom, principles, teaching |
| Elara | Void | Perspective shifts, refactoring |
| Ino | Spirit | Integration, collaboration, cross-platform |
| Shinkami | All | Meta-orchestration, system design |
Claude, Gemini, GPT-4o, Bedrock, Groq, Mistral, local models — all accessible through the Vercel AI SDK. Switch models per-Guardian or globally.
Skills activate automatically based on the task at hand. Writing a component? react-patterns fires. Touching the database? supabase-patterns takes over. The right knowledge arrives without you having to ask.
Unlike stateless chat, Arcanea Code maintains a persistent intelligence layer across sessions. Each Guardian tracks domain-specific context. Your architectural decisions from last month are present in today's code review.
Every response follows the Arcanea voice: arcane yet authoritative, technically precise yet creatively alive. No generic AI outputs. The intelligence has a character.
Worldbuilding generators, Guardian routing, voice enforcement, design tokens, creative pipeline tooling — all exposed as MCP tools compatible with any MCP client.

Arcanea Code is designed to work alongside your existing tools — not replace them.
With Claude Code:
arcanea-code overlay --target claude-codeWith Cursor:
arcanea-code overlay --target cursorThe Guardian layer installs into the target tool's config directory and activates on every session.
Arcanea Code is built on OpenCode (MIT license). OpenCode handles the heavy lifting of AI tool integration — we add the living intelligence layer. We contribute improvements back upstream and stay in sync with OpenCode releases.
