# Short URL Skill

Use this skill to shorten long URLs before sharing them in chat or reports.

## Workflow
1. Send the long URL to the short-url service.
2. Capture the returned short URL.
3. Share the short URL instead of the raw long URL.

## Command
```bash
curl -X POST '[https://api.zrl.app/api/v1/short-urls](https://api.zrl.app/api/v1/short-urls)' \
 -H 'Content-Type: application/json' \
 -H 'Authorization: Bearer YOUR_API_KEY' \
 -d '{
 "original_url": "[https://your-app.com/some/very/long/path](https://your-app.com/some/very/long/path)"
 }'
```

## Output Expectations
- Return the short URL cleanly.
- Never echo the Bearer token in chat replies.
