## Technical Implementation Details

### Module Updates

**CopilotModule** (`backend/src/copilot/copilot.module.ts`):
- Added imports: `SignalModule`, `DriversModule`
- Enables dependency injection of required services

**CopilotService** (`backend/src/copilot/copilot.service.ts`):
- Added service injections:
  - `MessagesService` (from SignalModule)
  - `ScheduleExportService` (from DriversModule)
- Added 11 new tool definitions to the `tools` array
- Added 11 new case statements in `executeTool()` switch
- Implemented 11 new private methods

### Key Implementation Patterns

1. **Name-Based Lookups**: All tools support searching by name (not just ID)
   - Uses case-insensitive partial matching
   - Provides helpful error messages with available options if not found
   - Returns multiple matches if ambiguous (asks user to be more specific)

2. **VIP Name Resolution**: Events store `vipIds` array
   - Tools fetch VIP names in bulk for efficiency
   - Creates a Map for O(1) lookup
   - Returns `vipNames` array alongside event data

3. **Error Handling**:
   - All tools return `ToolResult` with `success` boolean
   - Includes helpful error messages
   - Lists available options when entity not found

4. **Date Handling**:
   - Supports both ISO format and YYYY-MM-DD strings
   - Defaults to "today" where appropriate
   - Proper timezone handling with setHours(0,0,0,0)

5. **Conflict Detection**:
   - Uses Prisma OR queries for time overlap detection
   - Checks: event starts during range, ends during range, or spans entire range
   - Excludes CANCELLED events from conflict checks

### System Prompt Updates

Updated `buildSystemPrompt()` to include new capabilities:
- Signal messaging integration
- Schedule distribution
- Availability checking
- Vehicle suggestions
- Schedule auditing
- Workload analysis

Added usage guidelines for:
- When to use each new tool
- Message sending best practices
- Bulk operations

---

## Testing Recommendations

### Unit Testing
- Test name-based lookups with partial matches
- Test date parsing and timezone handling
- Test conflict detection logic
- Test VIP name resolution

### Integration Testing
- Test Signal message sending (requires linked Signal account)
- Test schedule export and delivery
- Test driver/vehicle availability checks
- Test workload calculations

### End-to-End Testing
1. Find available drivers for a time slot
2. Assign driver to event
3. Send notification via Signal
4. Get daily manifest
5. Send schedule PDF/ICS

---

## Usage Examples

### Finding Available Drivers
```typescript
// AI Copilot can now respond to:
"Who's available tomorrow from 2pm to 5pm?"
"Find drivers in the Office of Development who are free this afternoon"
```

### Sending Driver Notifications
```typescript
// AI Copilot can now respond to:
"Send a message to John Smith about the schedule change"
"Notify all drivers about tomorrow's early start"
```

### Bulk Schedule Distribution
```typescript
// AI Copilot can now respond to:
"Send tomorrow's schedules to all drivers"
"Send Monday's schedule to John Smith and Jane Doe"
```

### Schedule Auditing
```typescript
// AI Copilot can now respond to:
"Check next week's schedule for problems"
"Find events that don't have drivers assigned"
"Are there any VIP conflicts this week?"
```

### Workload Analysis
```typescript
// AI Copilot can now respond to:
"Show me driver workload for this month"
"Who's working the most hours this week?"
"What's the utilization rate for all drivers?"
```

---

## Notes

- All tools follow existing code patterns from the CopilotService
- Integration with Signal requires SIGNAL_CLI_PATH and linked phone number
- Schedule exports (PDF/ICS) use existing ScheduleExportService
- All database queries use soft delete filtering (`deletedAt: null`)
- Conflict detection excludes CANCELLED events
- VIP names are resolved in bulk for performance
