What problem does it solve? Managing recurring automated jobs often leads to schedule collisions, notifications firing in the middle of the night, and duplicate side effects when jobs re-run. This Skill validates cron schedules, enforces staggering rules, and gates delivery during quiet hours so autonomous jobs run predictably. ## Core Features & Use Cases - Collision-Free Scheduling: Enforces a maximum of one job per 5-minute slot and suggests the next available slot when a conflict is detected. - Quiet Hours Gating: Holds job output in a queue during 11 PM - 8 AM local time, with a user-awake override, and releases the backlog on morning contact. - Idempotency Enforcement: Requires checkpoint state files and existing-output checks so jobs can run twice without duplicate pages or timeline entries. - Use Case: You want a nightly job that syncs a multi-source brain. The Skill validates the cron expression, picks a non-colliding slot, writes a thin one-line prompt referencing the target skill file, and consolidates per-source sync entries into a single gbrain sync --all --parallel line. ## Quick Start Schedule a cron job that runs the weekly review skill every Monday at 9:05 AM and holds any output generated during quiet hours.
