# Cron Job Configuration - Issue #29

## Overview

Implement cron job configuration for Mosaic Stack, likely as a MoltBot plugin for scheduled reminders/commands.

## Requirements (inferred from CLAUDE.md pattern)

### Plugin Structure

```
plugins/mosaic-plugin-cron/
├── SKILL.md          # MoltBot skill definition
├── src/
│   └── cron.service.ts
└── cron.service.test.ts
```

### Core Features

1. Create/update/delete cron schedules
2. Trigger MoltBot commands on schedule
3. Workspace-scoped (RLS)
4. PDA-friendly UI

### API Endpoints (inferred)

- `POST /api/cron` - Create schedule
- `GET /api/cron` - List schedules
- `DELETE /api/cron/:id` - Delete schedule

### Database (Prisma)

```prisma
model CronSchedule {
  id          String   @id @default(uuid())
  workspaceId String
  expression  String   // cron expression
  command     String   // MoltBot command to trigger
  enabled     Boolean  @default(true)
  createdAt   DateTime @default(now())
  updatedAt   DateTime @updatedAt

  @@index([workspaceId])
}
```

## TDD Approach

1. **RED** - Write tests for CronService
2. **GREEN** - Implement minimal service
3. **REFACTOR** - Add CRUD controller + API endpoints

## Next Steps

- [ ] Create feature branch: `git checkout -b feature/29-cron-config`
- [ ] Write failing tests for cron service
- [ ] Implement service (Green)
- [ ] Add controller & routes
- [ ] Add Prisma schema migration
- [ ] Create MoltBot skill (SKILL.md)
