Feature request: Restrict URLs to a particular folder

I wanted to generate the llms txt for "Claude Code". Unfortunately, it spiders into ALL Claude documentation, including discovering URLs for other languages.

Here is the root URL:
https://docs.anthropic.com/en/docs/agents-and-tools/claude-code/overview

I'd love to be able to restrict it to map only the URLs beneath the `https://docs.anthropic.com/en/docs/agents-and-tools/claude-code/*` root URL.
