📅 Coordinate nudges with calendar events

[adrianwedd]

Summary

Create intelligent coordination between nudges and calendar events to provide seamless, context-aware support that respects meeting schedules and enhances productivity.

Core Coordination Features

Meeting Awareness

• Pre-meeting preparation: 15-minute, 5-minute, and 1-minute meeting reminders with context
• Do Not Disturb: Automatic nudge silencing during active meetings
• Post-meeting transitions: Support for context switching after meetings end
• Meeting type recognition: Different nudge behavior for different meeting types

Schedule Optimization

• Nudge timing: Schedule break reminders between meetings
• Focus block protection: Respect calendar focus time with minimal interruptions
• Travel time awareness: Account for commute time in nudge scheduling
• Buffer time utilization: Use small gaps for quick task nudges

Context-Aware Nudging

• Meeting preparation: Suggest agenda review, materials gathering
• Energy management: Schedule breaks during long meeting blocks
• Task coordination: Align task reminders with available calendar slots
• Priority adjustment: Urgent tasks get nudges before busy periods

Integration Scenarios

Daily Schedule Management

• Morning: "Your first meeting is at 10am. You have 90 minutes for focused work!"
• Pre-meeting: "5 minutes until 'Project Review' - time to gather your notes and take a breath."
• Between meetings: "15 minutes until your next call. Perfect time for that quick email task!"
• End of day: "Last meeting done! Time to capture any follow-ups before you switch off."

Focus and Productivity

• "I see you have 2 hours blocked for 'Deep Work' - I'll keep nudges minimal. Go get 'em!"
• "Your focus block ends in 15 minutes. Time to start wrapping up and preparing for your next meeting."
• "Great job in that long meeting! Your brain needs a movement break before the next one."

ADHD-Specific Support

• Transition warnings: "Big context switch coming - you have client calls after lunch. How are you feeling?"
• Hyperfocus protection: "I notice you've been coding through your lunch break. Your 2pm meeting is in 30 minutes."
• Executive function support: "Tomorrow is packed with meetings. Want to prep tonight while you're in planning mode?"

Technical Implementation

Calendar Integration

• CalDAV support for other calendar systems
• Event parsing and metadata extraction

Schedule Analysis

• Meeting block detection and categorization

Event-Driven Updates

• Real-time calendar change notifications

Calendar Event Classification

Meeting Types

• Focus blocks: Protected time requiring minimal interruptions
• Admin time: Good for task reminder nudges
• Social meetings: Preparation nudges for interpersonal context
• Client calls: Higher-stakes meetings requiring extra preparation
• Team meetings: Collaborative context nudges

Timing Considerations

• Duration awareness: Different nudge strategies for 30min vs 3-hour blocks
• Back-to-back detection: Special handling for consecutive meetings
• All-day events: Recognition of holidays, conferences, focus days
• Recurring patterns: Learning from weekly/monthly meeting rhythms
