wren

Link the user's Wren account so authored notes land in their notebook. Returns the linked uid when a credential is present; otherwise explains that account linking must be completed first.

Draw ONE standalone figure in the user's Wren notebook, big on its own page: a graph, labelled diagram, chart, table, timeline, flowchart, mind map, concept map, number line or shapes. Notes, explanations, worked examples, summaries or text to copy go to write_notebook_page (a figure that goes with text: a figure block there). No target: a new note. target.noteId: a new page at the end of that note (same topic -> same note); with target.pageNumber: drawn onto that page if Wren wrote it (mode append keeps its ink, replace redraws it). The result has a private link (noteUrl; opens in the user's Wren account after sign-in): give it to the user.

Show one note's title, subject, page size and its pages (number, id, ink stroke count, whether Wren can add ink to it). Use it to pick a page to replace (write_notebook_page target.pageNumber) or draw onto (draw_figure).

Return the stable Wren account id (Firebase uid) and basic profile of the currently linked account. Call this after connect_account to confirm linkage.

List the user's Wren notes, most recently edited first, with id, title, subject and page count. Use it to find the noteId for write_notebook_page, draw_figure or get_note.

The user's latest notes, newest first: id, title, subject, pages, last edit, the outline of pages Wren wrote, and the note this chat has been writing to. Use it when the user returns to a topic, then add pages to that noteId.

Plan a 1-30 page handwritten Wren notebook and write its cover and contents (page 1; over 8 pages: a cover page and contents pages). The cover is not a slot: slots are the content pages, numbered from 1. Then write each slot with write_notebook_page (target.noteId + planSlot), one call per slot. Pass noteId to extend a plan: new pages become the next slots after the existing ones. Same topic as an earlier note → pass its noteId. Optional: part (a topic group such as "Obstetrics", never a page title) per page; coverFigure (one on-topic sketch) makes a better cover.

Write a handwritten study page in the user's Wren notebook (same topic -> target.noteId, not a new note). Write a FULL page (not for verbatim): 110-140 words in 6-8 blocks (a table/figure = ~40 words), a heading per part, 3-6 key terms marked (underline/highlight; a mark copies exact words of its own block), every number+unit and formula marked as math (its latex keeps every word: 20\ \text{m/s}), one accent, at most 1 short marginNote, the takeaway in a callout (key_answer, key_idea) or summary. Pair two <=12-word callouts with layoutHint:"side_by_side". Unknown fields are refused. Editable ink, not the user's own handwriting. Recipes: worked_example = problem callout (box) + 3-4 steps (1-2 sentences + equation each) + Check heading+paragraph + common_mistake & key_answer callouts. concept_summary = definition callout + boxed equation or table/flowchart + 2 headings with 2-sentence paragraphs + key_idea callout. comparison_sheet = 1-sentence intro + 5-6 row table + heading+paragraph on why it matters + common_mistake & key_idea callouts (side_by_side). process_walkthrough = overview + 4-6 steps, each with label (stage name) + 1-2 sentences, optional flowchart showing what the steps don't + key_idea or summary. revision_sheet = 2-3 headings with concise paragraphs/equations + common_mistake & remember callouts (side_by_side) + 4-item checklist. verbatim = text the user gave you to copy: their words unchanged and once, in paragraph/heading blocks, nothing added.
