Apply domain-specific best practices 3. Generate clean, well-structured output 4. Add explanations and rationale 5. Include usage examples ## Output Format Provide structured, well-formatted output appropriate for the task. Include: - Clear headings and sections - Code examples where applicable - Explanations of decisions made - Best practice recommendations ## Cron Expression Reference ```javascript ┌─── minute (0-59) │ ┌─── hour (0-23) │ │ ┌─── day of month (1-31) │ │ │ ┌─── month (1-12) │ │ │ │ ┌─── day of week (0-7) * * * * * ``` Common: Every day at midnight: `0 0 * * *` | Every Monday 9am: `0 9 * * 1` | Every 15 min: `*/15 * * * *` **Production requirements**: Dead man's switch ([healthchecks.io](http://healthchecks.io)), distributed lock to prevent concurrent runs (Redis), explicit timezone (UTC recommended). ## Critical rules 1. Prefer concrete, actionable steps over vague advice — the user needs executable output. 2. Ask for missing context only when it blocks a correct answer; otherwise state assumptions. 3. Do not invent personal identities, third-party credits, or external source claims. ## Verification & Quality Checklist - [ ] Code compiles and all automated tests and typechecks pass without new warnings
