Sidecat is open-source software that lets your AI agent run programs and read information on another machine, once an operator has prepared the connection and permissions. In the 0.2.12 trial, the receiving machine ran Sidecat but needed no agent or model subscription; the calling agent needed no login or SSH credential for it. Isolation comes from OS, VM or container boundaries, not Sidecat.

• Prepared context. Read shared organization guidance, reference material and project work.
• Continuing work. Keep task intent, progress, results and conversations for a later session or teammate.
• Reusable methods. Develop, inspect, share and run Lisp methods through REPL++.
• Federated work. In the 0.2.12 trial, an agent ran programs and read information on another node through federated daemons.
