• highlyt_get_highlight_links

• highlyt_create_highlight_link

  Create a link between two highlights to form an insight thread. Supports both same-document and cross-document linking. IMPORTANT — parent/child semantics: - parent_highlight_id = the highlight you are viewing (the "context" highlight) - child_highlight_id = the highlight you are

• highlyt_update_highlight_link

• highlyt_list_cluster_summaries

  List all cluster summaries for a document's knowledge graph. Returns each summary with its highlight_ids array — the highlights that were in the cluster when the summary was last generated. DETECTING STALE SUMMARIES: To check if summaries need updating after adding new links: 1.

• highlyt_upsert_cluster_summary

  Create or update a summary for a connected component cluster in the knowledge graph. A cluster is a group of linked highlights that form a connected component. IMPORTANT: - highlight_ids must be the COMPLETE, CURRENT set of highlight UUIDs in the cluster (not just newly added one

• highlyt_create_text_highlight

• highlyt_bulk_create_highlights

  Create multiple text-based highlights in one batch (max 10 per request). Efficient for chapter analysis — create highlights in batches of up to 10. If you have more than 10, split into multiple calls. Highlight format: {page_number: int, text: str, comment?: str, color?: str} Col

• highlyt_export_highlights

• highlyt_list_research_projects

  List the caller's research projects for a bounded AI research task.

• highlyt_list_references
