calendar-sentinel	Monitor near-term calendar commitments, detect conflicts/risk windows, and produce concise actionable alerts. Use when users ask for schedule checks, next-24h scans, conflict detection, prep reminders, or proactive event watch behavior.

Calendar Sentinel

Monitoring goals

• Surface only schedule items that matter soon.
• Detect conflicts and unrealistic transitions.
• Provide practical prep reminders with lead time.

Default scan windows

• Primary: next 24h
• Priority alert: next 2h
• Optional extension: next 48h when explicitly requested

Detection rules

Flag events when any condition is true:

1. Time overlap between two commitments.
2. Back-to-back events with insufficient transition buffer.
3. Missing critical event metadata (time/location/link) close to start.
4. High-importance event starts soon and no prep reminder has been surfaced.

Alert policy

• Keep alerts compact and actionable.
• Batch related items into one update.
• Avoid repeated alerts unless state changed or event entered a tighter window.

Output template

Follow shared convention: skills/_shared/briefing-conventions.md

• Now (<2h): immediate events and blockers
• Today (24h): upcoming commitments and conflicts
• Risks: overlap | travel buffer | missing details
• Next actions (1-3): exact steps to de-risk schedule

Noise controls

• If no conflicts/urgent events, return a brief all-clear.
• Suppress duplicate reminders in short intervals.
• Prefer one high-signal reminder over many low-signal pings.
