How does the citation system work?

The skill tracks chunks and entities within its storage structure, enabling Claude to reference specific source documents when answering your questions.

What is the benefit of the 'hybrid' search mode?

Hybrid mode is the recommended setting as it combines local entity-level facts with global thematic analysis to provide the most comprehensive answer possible.

Does this skill require an external API key?

Yes, it requires an OpenAI API key to generate vector embeddings and process semantic queries through the LightRAG framework.

Is there a limit to the number of PDFs I can index?

The limit is primarily determined by your local storage and the token limits of your embedding model, but LightRAG is designed to handle large-scale document collections efficiently.

Can I index multiple directories of PDFs?

Yes, you can run the index command on any directory path, and the tool will build or update your knowledge graph accordingly.
