Amazing, sounds like an awesome improvement 🎉 And thanks a lot for the trick, definitely not something I was aware of, I'll have to take a look at it, sounds really good.

Thanks a lot for these incredibly kind words! Means a lot coming from you. The team is definitely eager to continue improving the Astro and Starlight ecosystem, and it's always amazing to read such feedback.

Really nice!

Small nit to the PR: `AGENTS..md` instead of `AGENTS.md` I assume (extra dot)

Available on both the Visual Studio Marketplace and the Open VSX Registry:

- marketplace.visualstudio.com/items?itemNa...
- open-vsx.org/extension/hi...

I'm not entirely sure it's exactly the same. It's similar in dev at request time but the linked file also contains another function used in prod which get all the infos for all files at once ahead of time. Altho, that may not be possible with your approach and constraints.
