Adds a "summary" link to each post on HN. Clicking the link opens either ChatGPT or Claude (one can choose) in a new tab with the prompt pre-poluated to summarise the post in question.

Very small. Surprisingly useful. Code here: https://github.com/JohannesSeikowsky/hn-summary-firefox-exte...

I'm not at all against reading posts in full, but often don't have the time. I also appreciate the option to ask follow-up questions in the LLM chat. That's what this is good for.

For those who don't use Firfox - you can probably just feed this into your coding agent of choice and tell it to whip up the same thing for your browser.
