What is beautiful-feishu-card?

A design and delivery guide for Feishu Interactive Cards, which are structured messages with layouts, links, and other interactive elements in the Feishu collaboration platform.

Use it to create, preview, send, and revise Feishu cards for status updates, meeting summaries, notifications, and reusable message templates.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00081	$0.01149
Opus 5	$0.00041	$0.00575
Sonnet 5	$0.00016	$0.00230
Haiku 4.5	$0.00008	$0.00115

Measured 8d ago against content hash e09669fabd91, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-11, from the pricing page.

Security

Grade A, and why

beautiful-feishu-card scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/send_card.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Beautiful Feishu Card

A design system and workflow skill for building visually stunning, highly readable Feishu Interactive Cards (Schema 2.0 JSON) wrapped in CardKit (.card) format and delivering them via lark-cli.

This skill transforms raw text materials, meeting notes, status reports, or doc links into beautifully formatted interactive cards that look modern, structured, and easy to read.

When to Use

When asked to create, design, or send a Feishu / Lark interactive card ("做一张飞书卡片", "生成卡片", "把这个通知做成卡片发我").
When sending summary reports, status updates, announcements, or notifications on Feishu and wanting them to look polished and professional rather than plain text.
When generating re-usable .card files for CardKit (Feishu Card Builder).

Core Workflow (5 Steps)

[1. Gather Material] ➔ [2. Design Schema 2.0 Card JSON] ➔ [3. Wrap in .card Format] ➔ [4. Deliver Interactive Card] ➔ [5. Iterate]

Step 1: Gather & Structure Material

From Doc/Wiki URL: Use lark-cli docs +fetch --doc "<url>" --doc-format markdown --as user to extract content.
From Text: Extract title, key points, status indicators, action items, dates, and links.
Images: If material contains images, download via lark-cli and upload to IM (/open-apis/im/v1/images) to obtain a valid image_key.

Step 2: Design Card JSON (Schema 2.0)

Follow the design guidelines in references/card-prompt.md and references/card-schema-guide.md:

Header Theme: Select 1 of 12 header color templates (blue, wathet, turquoise, green, yellow, orange, red, carmine, violet, purple, indigo, grey) matching the card's tone.
Visual Hierarchy:
- Header with bold title and clear subtitle.
- Dividers (hr) between major content blocks.
- Multi-column grids (column_set) for side-by-side metrics or status pairs.
- Badges & Highlights: Use <font color='...'>**[ Status ]**</font> in lark_md text blocks.
- Clickable Footer Link: End with <font color='grey'>💡 Generated by [Beautiful Feishu Card Skill](https://github.com/davidtoby/agent-skills)</font>.
Hard Rules:
- Schema: Must specify "schema": "2.0".
- No JSON comments.
- No fake image_key: Only include img components if a verified image_key is provided.
- No fake open_url: Only include button / links if valid URLs are provided.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
