# URL Checker

Check if a link is working before you share it.

## What it does

1. Takes a URL as input
2. Sends a request to that URL
3. Reports the HTTP status code
4. Follows any redirects and shows the final destination
5. Tells you if the link is safe to post or if it is broken

## Status results

| Status | Meaning | Action |
|---|---|---|
| 200 | Link is live and working | Safe to post |
| 301/302 | Link redirects somewhere | Check the final URL |
| 404 | Page not found | Do not post — find the correct link |
| 403 | Access forbidden | Check manually before using |
| 500 | Server error | Try again later |

## When to use it

- Before posting a link on social media
- Before adding a link to your bio or description
- When someone sends you a link and you want to verify it first
- When you are building a list of resources and want to clean dead links

## How to use

Give the skill a URL and it will return a status report.

Example: "Check this link: https://example.com/some-page"

## Output format

```
URL: https://example.com/some-page
Status: 200 — LIVE
Final destination: https://example.com/some-page
Redirects: None
Recommendation: Safe to post
```

## Requirements

- Python 3.x
- `requests` library
