+### Session Resumption Behavior
+
+By default, Claude Code automatically resumes existing conversations when your workspace restarts. Sessions are tracked per workspace directory, so conversations continue where you left off. If no session exists (first start), your `ai_prompt` will run normally. To disable this behavior and always start fresh, set `continue = false`
