Problem

The current llms.txt is probably wrong.

Analysis

That's how it should be:

llms.txt is essentially a sitemap, listing all the pages in the documentation.
llms-full.txt contains the entire documentation. Note this may exceed the context window of your LLM.

Sampling a few items from https://llmtxt.dev/hub tells the same story.

Solution

Adjust cratedb-about bundle to not expand the llms.txt: Just convert from cratedb-outline.yaml to Markdown instead.
