ZeroWidth Napkin

Sets cells in one tab of a sheet, by A1 address — values or formulas ('=SUM(B2:B9)'). Additive and surgical: only the addressed cells change. Check napkin_sheets_schema first so you know the tab names and where data ends; put headers in row 1 when creating a new region. To build a whole small table, write header cells + data cells in one call.

Edits a sheet's details: title, description, visibility, or `archived` (true takes it out of the gallery; false brings it back — the recovery move for a sheet created by mistake or no longer wanted). Cells are edited with napkin_sheets_set_cells, not here. Sheet ids come from napkin_sheets_list.

Renders one of a sheet's pinned charts against the LIVE data and returns the image so you can SEE it — the exact chart the user sees. The text part carries `imageUrl`; to show the user the chart inline in your reply, put a markdown image on its own line: ``. Use after napkin_sheets_add_chart to confirm the chart reads well, or whenever the user asks about a chart.

Appends one slide to an existing deck. Pick a layout (title | section | title-body | title-lead | two-column | three-column | comparison | statement | quote | closing | blank), give the title, and optionally `content` — markdown for the layout's remaining text areas, split by `---` lines (two-column/comparison take one block per column). Check the deck first with `napkin_deck_outline`.

Fills a slide's empty layout text areas by NAME — the names `napkin_deck_outline` surfaces as `[empty text stub: "…"]`. Pass `texts` mapping those exact names to content (markdown `- ` bullets welcome). Read the outline first to see which stubs a slide still has open.

Changes one slide as a whole: move it to another position in the deck (`moveTo`, 1-based — the other slides shift around it), hide it from the show without deleting it (`skipped`), show or hide its slide number (`pageNumber`), or replace its speaker notes (`notes`, markdown). Slide numbers come from napkin_deck_outline. To change what's ON the slide, use napkin_slide_fill or napkin_draw.

Renders a single slide of a Napkin deck to an image — exactly what present mode shows, cropped to the slide. Navigate by 1-based `slide` number in presentation order (get the map from `napkin_deck_outline` first; the result echoes `slideIndex`/`slideCount` so you can step through a deck slide by slide). Use this to check visual layout, drawings, and images that the text outline can't carry.

Adds columns to the end of a table. Existing records leave them empty.

Adds records, each a map of field name → value. Choices by option name (a new name becomes a new option); dates as YYYY-MM-DD; people by user id; checkboxes true/false. Every problem is reported at once and nothing is written until all records are valid.

Adds a saved view everyone sees: a grid (with where / sort), a board (lanes from a select or person column — groupBy), or a form people fill in to add records (formFields, formTitle, formIntro). A form's share link is made from the sheet's form view.

Makes a table tab — typed columns, one record per row, with grid, board and form views — in an existing sheet, or in a new sheet when sheetId is omitted. Use a table (not napkin_sheets_set_cells) for lists people keep: requests, vendors, bugs, contacts. The first column names each record. Column types: text, long_text, number, date, checkbox, select, multi_select, person, url, email.

Deletes records by id. People can undo this in the sheet only while it's open, so confirm with the person first.

A table tab's columns (name, type, choices), its views, and how many records it holds. Read this before writing records so field names and choices match.

Records from a table tab, keyed by field name, with optional where / sort / search / limit (max 500). For counts, sums and joins, napkin_sheets_query runs SQL over tables too (each table is an SQL table with an id column).

Changes some fields of records by id (from napkin_tables_query). Fields left out keep their values.

Search ZeroWidth product documentation. Returns matching pages with title, slug, public URL, and a query-relevant snippet. Use this when the user asks about a ZeroWidth product (Compass, Workbench, Caliper, Prism, Ledger, Napkin, the assistant), an API behavior, or a policy. No authentication required — the docs corpus is public.

Finds anything in the workspace in one call — uploaded files (searching the text inside them), folders, Workbench flows, shims, knowledge bases and tasks, Compass pages and changes, Caliper datasets, evals, rubrics, reviews, specs and sources, Ledger entries, Napkin sketches, decks, docs, sheets, diagrams and interfaces. The same search the person uses in Home. Use it FIRST whenever the user mentions something without saying where it lives ('the SOW', 'the dispatch interviews', 'that invoice'). The query is words in any order: each word must appear in the thing's name, its tags, the names of the folders it's filed under, or the text inside it — so 'northwind sow' finds the SOW filed in the Northwind folder, and 'dispatch interview' finds 'Dispatcher interview 1.md'. Results are ranked best first. Each hit carries its id, kind, path (for a link), folderPath (where it's filed, top-down), tags, and a snippet when the words were found inside it rather than in its name — say where a thing lives using folderPath. A file's id feeds workspace_files_read; other ids feed the kind's *_get tool. Pass folderId to search only inside one folder and everything under it. If nothing comes back, try fewer or different words before telling the user it doesn't exist. Results only include what the user can see, and only kinds this token may read.

Save a picture the user attached in THIS conversation to the workspace's files, in the Home folder "From chat", and get back its file id. Use it when the user wants a picture they sent you used somewhere — an interface shows it as <img src="file:<fileId>"> (CSS: url(file:<fileId>)). Pick the picture by `name`: the name in its `[attached image: <name>]` marker. Omit `name` only when the latest message with pictures has exactly one. Saving the same picture again returns the file it was already saved as. Only pictures from this conversation can be saved; a picture on a website can't be fetched, so ask the user to attach it here.
