Tools

• document_apply ~135 tokens
  Apply a proposal from document_propose_replacement to the document in this session's cabin (not to your original file). Stale proposal (the document moved on) is refused by the engine — propose again. Repeating an applied proposal is a no-op.
• document_comments ~63 tokens
  Comments (author, text, anchor, resolved) and tracked changes — up to 50.
• document_describe ~78 tokens
  Name, pages, paragraphs, words, number of comments and tracked changes, whether track changes is on. For documents; call first.
• document_export_pdf ~106 tokens
  Lay out the document as it is now in this session's cabin (after applied proposals, or as opened) and return a PDF download link valid for 24 hours, plus the page count. Documents only; for workbooks use document_save_copy.
• document_find ~86 tokens
  Paragraphs containing the text (case-insensitive), with snippets around the match.
• document_open ~221 tokens
  Open one of the demo files by name: documents footnotes, comments, forms, rtl, wild-horse, workshop, offer, tools; workbooks workbook, functions, macros, queries, gep, vba-web, sqlite, order-desk, onrr, cashflow, pivot, chart, notes, check, xtools. Default is footnotes. For your own file use documen
• document_open_file ~268 tokens
  Open YOUR file in a private editor cabin for this session: a .docx/.doc/.odt document or an .xlsx/.xlsm/.xlsb/.xls/.ods workbook, up to 50 MB. Give exactly one of: url (https link the server can fetch), base64 (file bytes; then name with the extension is required). Nothing in the file is executed. T
• document_propose_replacement ~188 tokens
  Propose the full new text of one paragraph (paragraph_index from document_read). Nothing changes yet: the editor core builds the change on a copy and returns before/after plus checks (numbers, dates, links kept). Then call document_apply with the proposal_id. Read the paragraph first.
• document_read ~141 tokens
  Paragraph text as a window: from = index of the first paragraph (0-based), count = how many (max 40). The answer carries next — where to continue, null at the end. A missing paragraph is a refusal, not an invention.
• document_save_copy ~163 tokens
  Write the document or workbook as it is now in this session's cabin (after applied proposals) to a copy and return a download link valid for 24 hours. Your original file is never touched. A workbook with macros comes back as .xlsm with the VBA project intact; a document keeps its styles, comments an
• macro_list ~72 tokens
  List VBA modules and runnable macros (entry points) in this workbook with their route and blockers. Runs nothing.
• macro_plan ~107 tokens
  Plan a macro run without running it: route, whether the engine can run it natively, blockers, instruction budget.
• macro_read_source ~98 tokens
  Read the source text of one procedure (module + procedure name from macro_list). Read-only; runs nothing.
• query_explain ~88 tokens
  Explain one Power Query query by name: its steps in order, where it loads, its connection. Reads only; refreshes nothing.
• query_list ~74 tokens
  List Power Query queries in this workbook: names, step chain, load target, connections. Reads only; refreshes nothing.
• sheet_apply ~138 tokens
  Apply a proposal from sheet_propose_edits to the workbook in this session's cabin (not to your original file); the engine recalculates. Refused if the workbook revision moved on since the proposal — propose again. Repeating an applied proposal is a no-op.
• sheet_describe ~103 tokens
  Workbook overview: every sheet tab with its used range, the current revision, and the header row of the sheet that is open. Call this first, then pass the tab name you need as "sheet" to sheet_read and sheet_find.
• sheet_find ~165 tokens
  Find cells whose value or formula contains the text (case-insensitive) in the used range of a sheet. ALWAYS pass "sheet" with the exact tab name when the workbook has more than one sheet: without it only the sheet that happens to be open is searched.
• sheet_propose_edits ~233 tokens
  Propose new contents for up to 20 cells (formulas like =SUM(B2:B9), or numbers/text). Nothing changes in the workbook: the engine previews the edits on the current revision and reports what would change and whether errors appear; the person decides whether to apply. Read the cells first. Do not over
• sheet_read ~196 tokens
  Read a rectangular range like A1:F20 (max 60 rows × 26 columns): values and formulas. Empty cells are omitted. ALWAYS pass "sheet" with the exact tab name when the workbook has more than one sheet — without it you read whichever sheet happens to be open, and the answer will quietly be about the wron
• workbook_inspect ~171 tokens
  Map the whole application model of this workbook in one call: sheets; VBA modules, procedures, which can run here and which are blocked and why; event handlers; external objects (CreateObject) and Windows API (Declare) dependencies; project references; Power Query queries; data connections; form con
