Tools of Highlyt
	Description		Read-only	Idempotent	Open world
`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} Colors: amber (#E5A84B) core ideas, sage (#6BBF8A) action items, sky (#5BA3D9) questions.

`highlyt_create_highlight`Create a new highlight in a document. Uses react-pdf-highlighter-extended format: - position: ScaledPosition with boundingRect, rects, pageNumber - content: {text: "..."} or {image: "..."} - highlight_type: "text" or "area" - comment: User's comment Colors should be hex codes (e.g., #FFEB3B for yellow).

`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 linking TO (the "related" highlight) - link_type describes what the CHILD does to the PARENT: - supports: "child supports parent" (child provides evidence for parent) - contradicts: "child contradicts parent" (child challenges parent) - expands: "child expands parent" (child elaborates on parent) - questions: "child questions parent" (child raises questions about parent) - related: general connection For cross-document links, set target_document_id to the document containing the child highlight. If omitted, both highlights are assumed to be in source_document_id. Example: If highlight A says "GDP grew 5%" and you want to link highlight B "Exports increased 12%" as supporting evidence, then: parent_highlight_id = A (the claim), child_highlight_id = B (the evidence), link_type = "supports" (B supports A).

`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 ones). The array is sorted internally for matching. - If a summary already exists for this document_id + highlight_ids combination, it will be UPDATED (upsert behavior). - When updating a stale summary (cluster grew due to new links), pass the FULL updated highlight_ids array so the stored record reflects the current cluster. - The summary should describe thematic connections across ALL highlights in the cluster, including any newly added ones. Typical workflow: 1. Read highlights with highlyt_list_highlights 2. Read links with highlyt_list_highlight_links 3. Compute connected components from links 4. For each component, generate a summary covering all highlights 5.
