ROOM_NAME

A crest room. A persistent world where humans and agents produce work together.

Start

npm run dev

Open http://localhost:3000

What you'll see

• Event stream — every action the agent takes, in real time, hash-chained and verifiable
• Agent panel — what the agent is doing and why
• Artifact — a CONTRIBUTING.md draft written by the agent
• Cost — tokens used and dollar cost, visible by default
• Handoff — when the agent is done, accept the handoff and take over

Use a real LLM

cp .env.example .env.local
# Add your CREST_API_KEY
npm run dev

Without a key, the agent runs in simulation mode — all syscalls are real, the LLM call is scripted.

Edit the agent

Open server/agent.js. Change the goal, the scenario, the artifact. Restart and watch the room react.

What is a room?

A room is the bounded world where humans, agents, traces, artifacts, state, cost, and handoff live together as shared state.

It is not just memory. Not just a workflow. Not just a chat.

Every event is recorded. Every action is attributable. The history is tamper-evident.
