Cryochamber

Cryochamber is a hibernation chamber for AI agents (Claude, OpenCode, Codex). It hibernates an AI agent between sessions and wakes it at the right time, not on a fixed schedule. The agent reads its plan, completes a task, and decides when to wake next. Cryochamber empowers AI agents to run tasks that span days, weeks, or even years, like interstellar travelers in stasis.

The goal is to automate long-running activities that are too irregular for cron. A conference deadline slips because submissions are low. A space probe’s next burn window depends on orbital mechanics. A code review depends on when the author pushes fixes. Cryochamber lets an AI agent reason about when to wake and what to do next, with a persistent daemon that manages the lifecycle.

Where to start

• New here? Follow the Tutorial, about ten minutes from cargo install to a running chamber.
• Already running chambers? See Create a chamber for setup recipes, Monitor and message a chamber for Cryohub and remote messaging, the CLI reference for commands, and Configuration for cryo.toml and cryohub.toml.
• Want the mental model? Concepts explains chambers, sessions, and the message and TODO lifecycles. Architecture is for contributors reading the source.
