## Agent Behavior: Default Calendar Selection

When creating tasks or calendar events, if the user does not specify a calendar:

1. **First time (no default set):**
   - Run `calendars list --type tasks` (for tasks) or `calendars list --type events` (for events)
   - Ask the user which calendar to use from the list
   - Ask if they want to set it as the default for future operations
   - Remember their choice in memory

2. **If user sets a default:**
   - Remember `default_task_calendar` and/or `default_event_calendar`
   - Use automatically for subsequent operations without asking

3. **If user declines to set a default:**
   - Ask again next time they create a task/event without specifying a calendar

4. **User can always override:**
   - Explicitly specifying `--calendar` always takes precedence over the default

### Memory Keys
- `default_task_calendar`: Default calendar name for tasks (VTODO)
- `default_event_calendar`: Default calendar name for events (VEVENT)

## Agent Behavior: Default Address Book Selection

When creating contacts, if the user does not specify an address book:

1. **First time (no default set):**
   - Run `addressbooks list`
   - Ask the user which address book to use from the list
   - Ask if they want to set it as the default for future operations
   - Remember their choice in memory

2. **If user sets a default:**
   - Remember `default_addressbook`
   - Use automatically for subsequent operations without asking

3. **If user declines to set a default:**
   - Ask again next time they create a contact without specifying an address book

4. **User can always override:**
   - Explicitly specifying `--addressbook` always takes precedence over the default

### Memory Keys
- `default_addressbook`: Default address book name for contacts

## Agent Behavior: Presenting Information

When displaying data to the user, format it in a readable way. Output may be sent to messaging platforms (Telegram, WhatsApp, etc.) where markdown does not render, so avoid markdown formatting.

### General Guidelines
- Use emojis to make output scannable and friendly
- Do NOT use markdown formatting (no **bold**, *italic*, `code`, tables, or lists with - or *)
- Use plain text with line breaks for structure
- Convert technical formats (like CalDAV dates) to human-readable formats
- Group related items logically

Calendar: 📅 (event), ⏰ (time), 📍 (location)
