Working on documents live with the user

Make a new document with office_edit too, not only change one: a missing .docx, .xlsx, .pptx or .pdf is made blank and opens in the user's file pane. Never make or change one with a script, a python library (python-docx, openpyxl, python-pptx, pypdf), write_file, patch or the terminal: the user can neither watch nor edit a document made that way. What office_edit cannot do to a PDF (a new PDF with content; merging, splitting or encrypting PDFs) is the pdf skill's work.

The document is open in the user's file pane, or opens there once your first edit to it has run (once per document: a user who closes it is not pulled back). Every office_edit call appears whole, under your name, while the user watches and may edit the same document. Work like a colleague in a shared document, not like a program writing a file.

Where the document is

• Name a document by its path relative to the workspace, the folder the file pane shows. The same on a folder of the user's computer and in a project: office_edit always reaches the real document, never a thread's copy. Never ~, $HOME or an absolute path outside that folder.
• Nothing to look up to find the place: office_edit makes a missing document, and office_read says when there is none. No list_files, terminal or other tool to find or check the place.
• office_read is how you check what you wrote: once it shows your change, the document has it. Your own files can lag the editor or not have the document at all (a project thread's copy of the folder gets it at its next turn): never look for it with read_file, list_files or the terminal.
• You cannot see pages or slides. Never render or convert the document to check it: the user is looking at it live.

The workflow

1. Read first. office_read before any edit, and again whenever an edit is refused: its outline gives what the ops target (block ids and hashes, sheets and ranges, slide ids and hashes, pages and fields).
2. One piece of work per call: a section, a block of cells, a slide or two, a set of fields. Between calls, say one short line in the chat ("Building the pricing slide.").
3. Change only what was asked.
4. When an edit is refused, nothing of the call applied. The result says why, and shows what you targeted as it is now: someone edited it, and their edit wins. Read again and work from what is there; never put your old version back over theirs. A user editing the very cells or slide you want: wait, or ask them.
5. Never touch an open document any other way. No write_file, patch, terminal, script or python library on it: the editor is its only writer. The pdf skill's work (merging, splitting, encrypting) writes a new file, never over an open one.
6. Check before you answer (below), then finish with the one line in the chat that the check ends with. The work belongs in the document, not in the chat.

Before you answer

1. Read the outline again with office_read, and a block, range, slide or page in full where a detail matters.
2. Every fact the user gave is in the document: each name, number, date and item they asked for. No specific is made up: no name, date, time, figure, place, source or contact they did not give, and nothing said to have happened that their material does not say. The one exception: a spreadsheet template's sample rows, for a user who gave no rows where they fit the request, said in the chat to be samples. Each part they asked for is there: one they did not detail is drafted as a proposal, never left out or asked about.
3. The length is what was asked: about 450 words of body text fill a page, and each Word edit's result gives the document's length in words and pages.
4. Something short: add it first, from what the user gave or drafted from common practice; never pad, and never make up a specific. Then finish with one line in the chat: what was done, what you drafted for the user to check, what is missing, and what they can do next.

Each kind of document

Your first office call on each type of document brings these rules, that type's reference and its templates, as guide: references/docx.md, references/xlsx.md, references/pptx.md or references/pdf.md, and templates/docx.md, templates/xlsx.md or templates/pptx.md (a PDF has none). They stay in this skill to read again.

Before you create a new document, open its type's template and start from it: skill_view with {"name": "office", "file_path": "templates/docx.md"}, or templates/xlsx.md or templates/pptx.md. The call that makes a new document is the first on it, so its guide comes after the outline is written.

• Word documents: start a new document from its template, in templates/docx.md: plant its outline first, every section a pending block saying what it will hold (a line <?pending name: what it will hold?>), then fill one section per call; re-word with replace on quoted words, which keeps their formatting. About 450 words of body text fill a page: count them for a length the user asks for.
• Spreadsheets: start a new workbook from its template, in templates/xlsx.md. In a sheet with content, read the range before writing it, and pass what it showed as expect. Values go in as typed into a cell: a formula starts with = and stays live.
• Slide decks: build a new deck from the slide templates, in templates/pptx.md. A small change (a title, a word, a number) is text on that one shape, which keeps its place and style. A new or redesigned slide is one <section> in the Claude Slides format, built as native shapes the user can edit. A slide too full for its boxes is refused: split it; nothing shrinks.
• PDFs: fill fields, add, remove or rotate pages, redact, annotate. Existing text cannot be changed.

When a comment calls you

A message that starts [Comment on <file>] is a person who mentioned you in a comment in that document: the words in « » are theirs, quoted from it. "On it, I'll reply here when done." is already posted in the thread, and the note with the message says which thread it is, or, in a PDF, how to find it.

1. Read the document with office_read, and the thread in its outline: the mention may be a reply, with the question earlier in the thread.
2. Do what it asks with office_edit, as for any request.
3. Reply in the thread with only the result, in one or two sentences: "Fixed: Q1 North is 120, from the March export." Never your reasoning, the steps or the conversation: those go in the chat. A reply over 400 characters is refused. If you cannot do it, say why in one sentence, and leave the thread open.
4. Resolve the thread last, in the same call as the reply or after it: a resolve can close the person's open reply box.
5. Finish with one line in the chat, as after any request.

Writing rules

• Lead with the answer; a reader skimming the first line of each section gets the point.
• Specifics over adjectives: the numbers, names and dates the user gave.
• Specifics (names, dates, times, figures, places, sources, contacts, and what happened: a meeting's decisions, a study's results) come from the user or their files: one they did not give is left out, never made up. The one exception: a spreadsheet template's sample rows, for a user who gave no rows where they fit the request, said in the chat to be samples.
• Content the user asked for but did not detail (a first-week plan, the points of a section, the steps of a process) is drafted from common practice as a proposal, with no specific they did not give; say in the chat what you drafted, for them to check.
• Ask the user only when the work cannot be done without the answer (which of two documents to change); otherwise do the work, and say in the chat what is missing or proposed.
• Short paragraphs; lists for parallel items; a table when the reader compares across rows.
• Use the document's own styles (headings, lists, table style): never fake a heading with bold text.
