description	A library of 37 curated colour palette styles for building beautiful, editable Feishu / Lark (飞书) whiteboards from SVG. Use this whenever the user wants to create or draw a Feishu whiteboard, infographic, diagram, poster, or visual explainer and wants it to look polished, on brand, or in a particular aesthetic, or when they name a style. The agent figures out what board the user wants, asks about the visual vibe, picks a fitting style from the catalogue, generates an editable Feishu whiteboard, returns the doc link and the rendered image, and offers to switch styles. Requires lark-cli (npm @larksuite/cli) installed and authenticated, and a Feishu/Lark account.

Beautiful Feishu Whiteboard

A design system skill: 37 colour palette styles plus the verified hard rules of the Feishu SVG whiteboard medium, so you can build gorgeous, on brand, editable whiteboards.

This is not an auto layout chart generator. You compose the layout. A template gives you a palette and mood; RULES.md gives you the medium's hard limits. The board you produce is a real, editable Feishu whiteboard inside a doc, not a screenshot.

When to use

• The user wants a Feishu / Lark whiteboard, infographic, diagram, poster, or visual explainer that should look good, branded, or in a specific aesthetic.
• The user names a style, or points at one of the templates.
• The user gives content ("explain X as a whiteboard", "turn this into a board") and wants it visual and editable inside Feishu.

Step 0: prerequisites (check before doing anything)

Run scripts/preflight.sh, or check manually:

• Node 20 or newer.
• lark-cli (npm package @larksuite/cli), installed and authenticated. If missing: npm install -g @larksuite/cli, then lark-cli config init (scan the QR), then lark-cli auth login.
• @larksuite/whiteboard-cli, used via npx, auto downloads, no install needed.
• A Feishu / Lark account. The board is written to the user's own tenant.

If lark-cli is missing or fails authentication (e.g., need_user_authorization), do not abort the task. Instead, generate the SVG, render it to a PNG locally via @larksuite/whiteboard-cli, and deliver the image directly to the user in chat using MEDIA:/path/to/diagram.png as a fallback. Explain that auth prevented live doc creation but the visual artifact is ready.

How to run the conversation

1. Understand the board. Find out what the user wants on it: the content, the purpose, the audience. If it is unclear, ask one short question before building.
2. Ask about the vibe. Ask the user what visual style they want, for example playful or professional, any colour or mood preference, or a brand to match. Offer to pick for them if they have no preference. If they already named a style, skip ahead.
3. Pick a style. Use CATALOG.md to match the content type and the requested vibe and formality to one of the 37 styles. Tell the user which style you chose and why, in one line.
4. Build it. Read RULES.md and the chosen templates/<slug>/design.md, then:
   • Compose the SVG in a logical space about 1600 to 1700 wide, in that palette, with native shapes only (rect, rounded rect, circle, ellipse, connectors, text). Lay the content out however reads best. Every label is a <text>; never set font-family.
   • Only the content goes on the board, never the instruction behind it. Do not print the user's prompt, scope notes, source citations, the chosen style name, or any "summary of… / 来源… / 风格…" meta line onto the canvas — that looks like a homework header. Such context belongs in your chat reply. (See the "Never echo the user's instructions" rule in RULES.md.)
   • Render it, then look at the image and correct yourself: fix text overflow, tight margins or padding, numerals touching edges, accidental overlaps, and clipping. Iterate render, view, fix until it is clean. (Commands and the full checklist are in RULES.md.)
   • Write it into a Feishu doc as an editable whiteboard, then view the live board image too and fix any remaining layout issues.
5. Deliver. Give the user both: the Feishu doc link and the rendered image itself, so they can see it without opening the doc. Then tell them they can switch to a different style any time, and you will re render the same content in the new palette.
