Try all words as URLs (announce just the first, or all of them?)
In case 4, possibly handle cases where the URL is followed by non-whitespace, for example "hey jane, check out https://gnu.org, cool thing". Can a URL contain a comma as the last char? Is there a good way to strip those suffixes, at least common ones like comma? If yes, support it. If not, it's fine too, just a bonus.
Instead of simple on/off support these:
1. No title annoucenements
2. Take the entire message as the URL
3. Take the first word as the URL

You could make a GET to the url with the comma. If you get a 404, try without the comma. If it also 404's, announce a dead link.
