`draw_figure`Draws one standalone figure in the user's Wren notebook, large on its own page: a graph, labelled diagram, chart, table, timeline, flowchart, mind map, concept map, number line or shapes. Figure only, no text blocks (write_notebook_page pages can hold figure blocks next to text). No target: a new note. target.noteId: a new page at the end of that note; with target.pageNumber: drawn onto that page if Wren wrote it (mode append keeps its ink, replace redraws it). The result includes noteUrl, a private link that opens in the user's Wren account after sign-in.

`get_note`Returns one note's title, subject, page size and its pages (number, id, ink stroke count, whether Wren can add ink to it). Page numbers match target.pageNumber in write_notebook_page and draw_figure.	Returns one note's title, subject, page size and its pages (number, id, ink stroke count, whether Wren can add ink to it).

`list_notes`Lists the user's Wren notes, most recently edited first, with id, title, subject and page count. The noteId works as target.noteId in write_notebook_page and draw_figure, and as noteId in get_note.	Lists the user's Wren notes, most recently edited first, with id, title, subject and page count.

`list_recent_notebooks`Returns 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.

`plan_notebook`Plans a 1-30 page handwritten Wren notebook and writes 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. Each slot's page is written by write_notebook_page with target.noteId + planSlot, one page per call. With noteId, the plan extends that existing note: new pages become the next slots after the existing ones. Optional per page: part, a topic group such as "Obstetrics" (separate from the page title). Optional coverFigure: one on-topic sketch drawn on the cover.	Plans a 1-30 page handwritten Wren notebook and writes its cover and contents (page 1; over 8 pages: a cover page and contents pages).

`write_notebook_page`Writes one handwritten study page into the user's Wren notebook as editable ink, not the user's own handwriting. With target.noteId the page is added to that note; without it, a new note. 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's text is 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. layoutHint "side_by_side" pairs two callouts of up to 12 words. Unknown fields are refused. Page kinds: 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 = the user's own text, unchanged and once, in paragraph/heading blocks, nothing added.
