Thanks, that’s a good point. Yeah, it makes retrieval look like function calling or tool selection, which I guess makes the idea more generic and better suited to current AI systems like MCP.

For the ToC generation quality, you can try our API: https://docs.pageindex.ai/ or the open-sourced version: https://github.com/VectifyAI/PageIndex. I didn’t realize other people were working on similar ideas or had similar packages. It would be great if you could share the links to the AI agent you mentioned. Thanks!
