ZeroWidth Napkin

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, zv1), an API behavior, or a policy. No authentication required — the docs corpus is public.

Fetch the full Markdown body of a specific docs page by its slug. Use this after `search_docs` when the user needs the complete content of a page. No authentication required.

Enumerate all available docs pages, optionally filtered by product (e.g. 'compass', 'legal', 'overview'). Use this to discover what slugs exist before calling `get_doc`. No authentication required.

Lists the comment threads on one workspace entity (open first, then resolved) with authors and timestamps. Read this before weighing in on contested work — the threads are where disagreement lives before it becomes a decision.

Posts a comment on a workspace entity — a new thread, or a reply when rootId is given. Use it to leave findings where the discussion already lives (an eval result on the flow being debated, a summary on a long thread). Mention people via mentionedUserIds (from workspace member ids) to ring their notification bell; never mention someone who didn't ask to be pulled in.

Sets a comment thread's resolved state (rootId = the thread's root comment id). Resolve ONLY when the human asked or the thread's question is demonstrably settled — and say what settled it in a reply first. Reopening is for new evidence.

Lists sketch boards in the active workspace — name, id, kind (sketch / deck), shape count, last activity. Boards are SPATIAL canvases (drawing, diagrams); the markdown DOCUMENTS are docs — napkin_docs_list. Archived boards are hidden unless `includeArchived`; `q` narrows by name. When the user mentions a sketch, drawing, whiteboard, or napkin, find it here, then LOOK at it with `napkin_boards_

Returns a board's shapes as data — each with its id, kind, position, size, and text — so you can TARGET one to change or remove with napkin_draw (`updates` / `deletes` take these ids and absolute board coordinates). Pen strokes come back as a point count, not the points. For what the board LOOKS like, use napkin_boards_view instead. Board ids come from napkin_boards_list.

Renders the sketch board to an image and returns it so you can SEE what's drawn — layout, arrows, handwriting-style strokes, sticky notes — not just data about it. Use this before answering any question about a sketch's contents, and cite the board when you do — `[[board:ID]]` alone on its own line embeds the sketch card in your reply.

Edits a board's details: name, description, visibility, or `archived` (true takes it out of the gallery; false brings it back — the recovery move for a board you created by mistake or the user no longer wants). Board ids come from napkin_boards_list. Boards are working material: no approval card, every change attributed.

Returns a Napkin deck as a markdown outline — one section per slide in presentation order, with slide titles, text content (bold + bullets preserved), empty layout stubs still awaiting content, and a summary of drawn marks. This is the cheap way to know what a deck SAYS; use `napkin_slide_view` when you need to see how a specific slide LOOKS. Works on any board that has slides. Cite the deck wit

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.

Creates a blank Napkin board — a sketch (free canvas) or a deck (slides). NOT for written documents: 'draft/write a doc, note, memo' is napkin_docs_create. Use when the user asks for one, or proactively when a sketch/deck would carry the conversation better than words; hand it over with `[[board:ID]]` alone on its own line. For a deck with content, prefer `napkin_deck_write` (one call, whole dec

Creates a deck from a markdown outline — the SAME dialect `napkin_deck_outline` reads back, so any deck you've read shows the format. Decks are SLIDES for presenting; a prose document ('write this up', 'draft a doc') is napkin_docs_create instead. Rules: `## Heading` starts a slide (heading becomes the slide title and its biggest text block); optional trailing `[layout: title | section | title-b

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.

Draws shapes, strokes, and labels on a board — diagram on a sketch, annotate a deck slide — and, via `updates` / `deletes`, changes or removes shapes that are already there (ids from napkin_boards_get; the fix for something you drew wrong). For NEW elements never compute absolute board coordinates: with `slide`, coordinates are slide-local — (0, 0) top-left to (960, 540) bottom-right of that

Paints every slide of a deck with a theme — slide background, heading and body typefaces, and text colors — in one call, the same as picking it in the deck's theme menu. Font sizes are kept. Prefer "brand" (the workspace's own brand kit) unless the user asks for something else. Built-in themes: plain (Helvetica on white. Gets out of the way.); editorial (Garamond headings on cream. Reads like

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.

Lists the workspace's brand kits: id, name, description, and which one is the workspace's brand (`isDefault`). Most workspaces have one. Use napkin_brand_get to read a kit.

Reads a brand kit — the workspace's brand unless you name another. READ THIS BEFORE writing or designing anything for the workspace: a deck, a doc, an interface, copy. Returns `brief` (the whole kit as markdown: every section — overview, voice, colors, typography, imagery, motion, and whatever else the team wrote — with the reason behind each rule; follow the reasons when a case isn't covere

Finds words the brand says to avoid in a piece of writing, with what to say instead and why. Pass `text`, or a deck (`boardId`) or doc (`docId`) to check its words. Run it on your own drafts before handing them back.

Restyles a piece in the brand — the workspace's brand unless you name a kit. `deck` (a board id): every slide gets the brand's background, typefaces, and text colors; sizes are kept. `interface` (an interface id): rewrites its brand.css, so anything styled with var(--brand-*) updates. `accent` makes one of the kit's colors the piece's accent — use it when the piece is about one product or camp

Creates a new brand kit, or edits one that is NOT the workspace's brand. Use it when someone asks you to put their brand together (from their site, a deck, or what they tell you) or to try a variation. You can't change the workspace's brand itself — make a draft and tell the user they can choose it in Napkin's Brand section. A kit is a document of sections, each with `title`, `kind` (overview, v

Gets the font files for a kit's typefaces from Google Fonts and keeps them in the kit, so decks, slide pictures and the canvas draw the brand's real typefaces instead of a stand-in. Only typefaces that name a family (like Poppins) and don't have files yet are fetched. Works on any kit, including the workspace's brand: it adds the files for the typefaces the kit already names and changes nothing el

Shows you the pictures in a kit's Examples sections — screenshots of work that gets the brand right — with each one's note on what makes it good, plus the example links. Look before you design a deck, page or interface in the brand, and hold your work to the same bar: the layouts, density, type sizes and use of color you see there.

Adds pictures to a brand kit section — logo versions, product marks, example screenshots, imagery. Each file comes from a public https `url` (fetched by the server) or, for a small file that isn't online, base64 `data` with a `filename`. PNG, JPEG, WebP, GIF and SVG, up to 20 MB each. Every file becomes a workspace file and an asset on the section, appended after the ones already there. Give eac

Look at the pictures in a brand kit — logos, product marks, footage stills, layout references, examples — before you use them. Without `section` or `names` it lists every picture by section with its note, so you know what exists. With `section` (a section title, like Imagery) or `names` (pictures' names as the brief lists them) it shows you those pictures, up to 8 at a time. Look before you bu

Exports a deck's slides as PNG files at each slide's real pixels — a square post at 1080×1080, a story at 1080×1920, a leaderboard at 728×90 — ready to upload to an ad platform or a social post. One slide comes back as a PNG; several as a .zip named by deck, slide and size. Hidden slides are left out. The file is saved to the workspace's files; give the user `downloadUrl` (it opens for anyo

Lists the slide layouts napkin_deck_compose can build from — the brand kit's own first, then the built-in ones — with when to use each and the slots it takes (`needs` must be filled; `takes` are optional). Every layout adapts to every size, fits its text, and uses the brand's colors, faces and logos; the logo fills itself in. Pick by what the slide has to say: one line (statement), a number (s

Builds a designed deck: each slide is a layout with its slots filled, or HTML and CSS you write; a real browser lays it out, and it becomes an ordinary Napkin deck people can edit. Use this whenever a deck should look designed — it's how to get layout, big numbers, color blocks, and pictures right. LAYOUTS FIRST - For ads, posts, carousels and title slides, start from a layout (napkin_layouts_l

Lists the workspace's Napkin docs (quick markdown documents — drafts, notes, working text; the LINEAR surface, distinct from boards which are drawing canvases) newest first, with excerpts. Archived docs are hidden unless `includeArchived`; `q` narrows by title. Fetch one with napkin_docs_get. When referring the user to a doc in your reply, put `[[doc:ID]]` alone on its own line — it renders as

Fetch one Napkin doc's full markdown body by id (from napkin_docs_list). Read before editing — napkin_docs_update replaces or appends against the current body.

Create a Napkin doc — a markdown DOCUMENT (prose, structure, code blocks), not a drawing canvas (that's napkin_boards_create) and not slides (napkin_deck_write). Optionally pass a title and initial markdown body. Use for drafts the user asked you to start. After creating, cite it as `[[doc:ID]]` alone on its own line — it renders as a clickable card. NEVER cite it as [[board:ID]].

Edit a Napkin doc. For a change to existing prose use `edits` — a list of exact find/replace pairs, which is the SAFEST option and the one to reach for by default: it leaves everything you did not target untouched, and it fails loudly rather than clobbering a doc somebody else is typing in. `append` adds a section at the end. `body` replaces the WHOLE document and should be a last resort. Also r

Lists the workspace's Napkin sheets (multi-tab spreadsheets — the small-data surface) newest first with tab/chart counts. Archived sheets are hidden unless `includeArchived`; `q` narrows by title. Inspect one with napkin_sheets_schema, then query it with napkin_sheets_query.

Returns a sheet's tabs as SQL table definitions — CREATE TABLE scripts with row counts (each tab is a table; its header row names the columns; formula cells contribute computed values). Read this BEFORE writing a napkin_sheets_query so your SQL matches the real tables.

Runs a SQLite SELECT over a sheet's tabs-as-tables (get the table/column names from napkin_sheets_schema first). Full SQLite dialect: WHERE, GROUP BY, ORDER BY, JOINs across tabs, aggregates. Results cap at 200 rows. This is THE way to answer questions about a sheet's data — never eyeball cells when a query can answer precisely.

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.

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.

Adds a LIVE chart to a sheet — its SQL re-runs against the tabs on every view, so it never goes stale. Write the query with napkin_sheets_query first to confirm the shape (first column = x axis, numeric columns = series, or set x/series explicitly). Prefer aggregated queries (GROUP BY) — a chart of raw rows is rarely the answer.

Creates a Napkin sheet (multi-tab spreadsheet), optionally titled. Then populate it with napkin_sheets_set_cells (headers in row 1). Tell the user where it landed — the Sheets tab in Napkin.

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.

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).

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.

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.

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

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

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

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.

Lists the workspace's Napkin diagrams (interactive flowcharts — processes, decision trees, system maps) newest first. Archived diagrams are hidden unless `includeArchived`; `q` narrows by title. Fetch one's mermaid source with napkin_diagrams_get. When referring the user to a diagram in your reply, put `[[diagram:ID]]` alone on its own line — it renders as a clickable card. NEVER cite a diagra

Fetch one Napkin diagram's mermaid source by id (from napkin_diagrams_list). Read before editing — napkin_diagrams_update replaces the whole source.

Create a Napkin diagram — an interactive FLOWCHART (process, decision tree, system map), not a doc (napkin_docs_create) or drawing canvas (napkin_boards_create). Pass the mermaid source. Use for process maps the user asked you to draw. After creating, cite it as `[[diagram:ID]]` alone on its own line — it renders as a clickable card. NEVER cite it as [[board:ID]].

Edit a Napkin diagram: retitle, describe, REPLACE the whole mermaid source, set visibility, or `archived` (true takes it out of the gallery, false brings it back — the recovery move for a diagram created by mistake). Read the diagram first (napkin_diagrams_get) so your new source keeps the parts the user wants. Diagram ids come from napkin_diagrams_list.

List the interfaces in a workspace — small self-contained screens (a custom chat, a control panel, a prototype) that run on their own origin and can call the flows they've been granted. Returns ids, names and how many flows each may run.

Read one interface: its name, the flows it may run (with the published version each is pinned to), and the contents of its files. READ BEFORE EDITING — napkin_interfaces_write matches text exactly against what is there now. Pass a path to read one file when the interface has several. An interface is plain HTML, CSS and JavaScript in one or more files, served from its own origin. Put styles in a

See what an interface LOOKS like and DOES right now: the page RUNS from its current files under the same rules as the live page (no web fonts, no remote pictures), and you get a picture plus anything that went wrong (script errors, failed promises, blocked requests, console errors). Use it after every write and before saying an interface is finished: reading the code tells you what you wrote, not

Create an interface — a small screen of its own the user can open and send to people. Use when someone asks for a custom chat UI, a little tool, or a prototype of how something would feel in their product. It starts with a working index.html you then edit. It can reach NOTHING in the workspace until a flow is granted with napkin_interfaces_grant. Cite it in your reply as `[[interface:ID]]` alone

Write one file of an interface. Use `edits` — exact find/replace pairs — which is the SAFEST option and the one to reach for by default: it leaves everything you did not target untouched, and it fails loudly rather than clobbering a file somebody is editing. `body` replaces the WHOLE file and is for a new file or a deliberate rewrite. ONE CALL HOLDS ABOUT 15,000 CHARACTERS of file: a longer `b

Save where an interface is now as a numbered version. Share links point at a published version, so what someone was sent doesn't change while work continues. Do this when the user says it's ready to show people, not after every edit.

Set what an interface may run — flows and shims, each pinned to a published version. This is the interface's ONLY reach into the workspace, and it replaces the whole list, so include everything it should keep. Ids and published versions come from workbench_flows_list / workbench_shim_list and their revisions. Ask the user before widening this.

Set the sheet tables, Ledger metrics and Workbench Tasks an interface may use (ADR 0085, 0086), replacing the whole list. Tables: access read, add (read and add records) or edit (also change and delete); optionally limit to some columns by name. Metrics: read or record. Tasks: the page may start them. The page then calls zw.tables.query / add / update / remove, zw.metrics.read / record and zw.task

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 men

Returns the tags on a batch of entities of one kind — the labels galleries organize by. Ids come from the kind's list/get tool or from search_workspace. Use it before entity_tags_set so you replace the full set knowingly, and to answer 'what is this filed under'. Entities the user can't see are omitted.

Without a tag: every tag in use across the workspace with how many entities carry it, most-used first — the vocabulary the team already organizes by. With a tag: everything filed under it across every tool, each with its kind, id, title, and path. Use it to reuse existing labels instead of inventing near-duplicates, and to answer 'show me everything about X' when X is a label.

Replaces the FULL tag set on one entity (an empty list clears it). Read the current tags with entity_tags_get first and pass the merged list — this is not additive. Tags are lowercase letters, numbers, spaces, and hyphens; prefer labels already in use (entity_tags_browse) so the workspace's vocabulary stays small. The id comes from the kind's list/get tool or search_workspace.

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 me
