Getting started

Install the hotcell daemon and run your first contained agent.

Placeholder page — the scaffolding is real, the prose is a stub. Replace with actual docs before deploying.

Install

npm install -g hotcell

Start the daemon

hc daemon &   # REST :4750 · preview :4751 · egress gateway :4752

Run a contained agent

hc run --egress --spend-cap 5 "claude 'fix the failing tests'"

The sandbox gets a revocable egress token with a hard $5.00 spend cap and default-deny egress — the gateway is the only way out.

Shape egress policy

hc egress <sandbox> --spend-cap 5 --models 'claude-*' --rate-calls 60 --rate-window 1m --ttl 24h

Dashboard

Open 127.0.0.1:4750 for the live terminal, metrics, cost meter, and preview links.
