Here's a Convex agent skill for a sales forecasting application using the Hook tool. This skill includes a cron job pattern that runs daily to analyze customer interactions and update sales forecasts.

```javascript
// salesForecastingAgent.ts
import { cronJob } from 'convexskills'

const salesForecastingAgent = cronJob({
  name: 'updateSalesForecasts',
  interval: 'daily',
  handler: async (ctx) => {
    const customers = await ctx.db.query('customers').collect()
    const interactions = await ctx.db.query('interactions').collect()
    
    for (const customer of customers) {
      const recentInteractions = interactions.filter(
        (interaction) => interaction.customerId === customer.id
      )
      
      // Use Hook tool to analyze interactions and update forecast
      const forecast = await Hook.analyzeInteractions(recentInteractions)
      
      await ctx.db.patch(customer.id, {
        salesForecast: forecast,
        lastUpdated: new Date()
      })
    }
  },
})

export default salesForecastingAgent
```

This skill integrates with the Convex backend by:
1. Querying the customers and interactions tables
2. Using the Hook tool to analyze interactions
3. Updating the sales forecast for each customer
4. Recording the last update timestamp

The cron job runs daily to ensure forecasts are up-to-date.
