The description that tells Claude how this tool works was rewritten in this release, in the main system prompt (the standing instructions Claude receives at the start of a conversation) for both the command line and the SDK.\n\nThe current description still covers these points:\n\n- Scheduled jobs only run while Claude Code is idle, not in the middle of answering\n\n- Durable jobs are saved to `.claude\/scheduled_tasks.json` and resume automatically the next time Claude Code starts\n\n- One-time durable tasks missed while Claude Code was closed are brought up for catch-up\n\n- Session-only jobs end when Claude Code exits\n\n- The scheduler shifts run times slightly: repeating tasks can fire up to 10% of their interval late (at most 15 minutes), and one-time tasks set for :00 or :30 can fire up to 90 seconds early\n\n**Why**\n\nThese instructions shape how Claude sets up scheduled tasks for you, such as which times it picks and whether it makes a job last across restarts, so a change in wording can change how it schedules things.\n\n- Area: Scheduled Tasks\n- Names: `CronCreate`\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 0\/5\n- Scope: individual\n- Heads-up: no"}
