Building Gnosis: A Multi-Agent Terminal with a 3D Office UI

Description and use

Gnosis visualizes multi‑agent AI work in a 3D office, improving clarity and cutting prompt costs.

Managing multiple AI agents in a terminal is hard to visualize and understand, leading to confusion and inefficiency.

Gnosis reduces visual clutter, improves agent traceability, and cuts prompt costs by 12×, while supporting model hot‑swapping and extensive tooling.

1. Install Gnosis via npm.
2. Launch the local server; the React + Three.js UI renders the office.
3. Agents are spawned and assigned to zones (Coordinator, Planning, Coding, Application, Sub-Agents).
4. Users click an agent to view its session and logs.
5. Mid-session, switch OpenRouter models without losing context.
6. Use built‑in tools (Tree‑sitter indexing, file browser, diff viewer, etc.) to interact with code.
7. Monitor performance and cost via prompt caching metrics.

One measured request dropped from $0.0252 to $0.0021 — a 12× reduction

Gnosis also includes: Tree‑sitter code indexing, Scoped sub‑agents, Local PTY terminal streaming, Obsidian persistent memory, etc.
