+## State Persistence
+
+AgentAPI can save and restore its conversation state to disk across workspace restarts. This complements `continue` (which resumes the Codex CLI session) by also preserving the AgentAPI-level context. Enabled by default, requires agentapi >= v0.12.0 (older versions skip it with a warning).
