Claude Code runs scheduled loops for ideas

Claude Code's native loop feature schedules recurring prompts, automating tasks from build fixes to daily digests within your active session.

Claude Code's built-in loop feature allows you to schedule recurring prompts at intervals ranging from one minute to three days. This enables automation for tasks like fixing builds, summarizing communications, or generating daily reports directly from your CLI. Unlike external cron jobs, Claude Code loops maintain session context, allowing the agent to build on previous iterations. Loops are session-scoped and run while your Claude Code session is active, providing a safe and controlled environment for iterative work. For durable automation beyond an active session, consider GitHub Actions or Claude Desktop app's scheduling.
