Many harnesses, many models, one safe environment.

Frontier models and coding harnesses evolve every quarter. By decoupling intelligence from the runtime fabric, your team can switch between Cursor, Claude Code, Codex, and Pi — or swap models like Composer, Claude, Grok, and Mistral — without migrating your infrastructure or rewriting stack.json.

Every agent works on an isolated git branch (agent/<id>) and a dedicated sandbox environment with an explicit permission and credit ceiling. Production keys and main branches remain under human engineering control.

Stakeholders and partners can mention @agent in the project conversation from the web console, Telegram, or WhatsApp. The agent builds on a preview branch and replies with a secured preview URL.
