Tapestry visual-card
Generate professional visual note cards (视觉笔记卡片/信息图) from knowledge base content as single-page HTML infographics with PNG export. Use when users want to create visual summaries, knowledge cards, infographics, or poster-style visualizations of topics from the knowledge base.

Generate professional visual note cards from knowledge base content: $ARGUMENTS
When to use this skill
Use this skill when:
- A user wants to create a visual note card or infographic from KB content
- The user asks to "visualize", "create a card", "make an infographic", or "generate a visual summary"
- The user mentions 视觉笔记, 知识卡片, 信息图, or one-pager summary
- You need to present knowledge base content in a shareable, poster-style format
- The user wants to export KB content for social media or presentations
Purpose
This skill transforms structured knowledge base content into beautiful, information-dense visual cards following an editorial magazine aesthetic. It produces:
- A self-contained HTML file with embedded styles and export functionality
- A high-quality PNG image (via Playwright rendering)
The cards follow a fixed layout structure optimized for readability and social sharing.
Workflow
Architecture: Agent-Driven Content Synthesis
This skill uses an Agent-driven approach where the Agent reads the template specification and autonomously decides how to map source content to template blocks.
Key principle: The template structure is fixed (7 display blocks), but content mapping is intelligent and adaptive.
Step 1: Identify the Source Content
Resolve the target from the argument:
- If a specific chapter path is provided (e.g., "ai-and-development-tools/ai-agent-architecture.md"), use that chapter
- If a topic is provided (e.g., "ai-and-development-tools"), offer to generate cards for its chapters
- If no argument, list available topics and ask the user to choose
# List available topics ls -d data/books/*/
Step 2: Run the Context Preparation Script
python visual-card/_scripts/generate_card.py --chapter "<topic>/<chapter.md>"
This prints a JSON object with three keys:
: the raw chapter markdownsource.content
: parsed metadata (title, author, date, etc.)source.frontmatter
: full natural language spec of the 7 template blockstemplate_specification
: task descriptioninstructions
Step 3: Read the Template Specification
Read
visual-card/_templates/card_template_spec.md to understand:
- What each of the 7 blocks is for
- Quality criteria for content selection
- Expected JSON output format with examples
Step 4: Synthesize the Content Mapping (Agent Task)
Analyze the source content against the template spec and produce a synthesis JSON. Write it to a temp file:
# Write synthesis to temp file cat > /tmp/card_synthesis.json << 'EOF' { "metadata": { "chapter": "<chapter-name>", "title_en": "<English title, 3-8 words>", "title_cn": "<Chinese title>", "topic_label": "<TOPIC LABEL IN CAPS>", "source_label": "<SOURCE IN CAPS>", "thesis": "<one sentence with <strong>keyword</strong> embedded>" }, "framework": { "formula": "<A × B × C format>", "formula_subtext": "<what the formula means>", "label": "<FRAMEWORK NAME>", "components": [ {"letter": "A", "name": "Component Name", "description": "One-line description"} ] }, "insights": [ {"number": "01", "title": "Insight Title", "description": "2-3 sentence insight description"} ], "dark_panel": { "icon": "⚡", "section_title": "<Section Title>", "block1": {"title": "<Block 1 Title>", "items": ["item 1", "item 2", "item 3"]}, "block2": {"title": "<Block 2 Title>", "items": ["item 1", "item 2", "item 3", "item 4"]}, "conclusion": {"label": "核心洞察", "text": "<conclusion text>", "highlight": "<highlighted phrase>"} }, "closing_thought": { "text": "<memorable closing insight>", "attribution": "<author or source>" } } EOF
Content decisions to make:
- Framework: Identify 2-6 core concepts that structure the topic (acronym or logical grouping)
- Insights: Select 3-5 most surprising, actionable, or paradigm-shifting points
- Dark panel: Narrative flow — overview → key mechanics → conclusion
- Thesis: A single provocative claim that captures the article's core argument
- Closing thought: A memorable synthesis that gives the reader something to carry away
Step 5: Generate HTML/PNG from Synthesis
python visual-card/_scripts/generate_card_from_synthesis.py \ --synthesis /tmp/card_synthesis.json \ --chapter "<topic>/<chapter.md>"
This renders the synthesis into the HTML template and exports PNG via Playwright.
Step 6: Present the Results
Report back with:
- The generated PNG path (primary deliverable)
- The HTML path (for browser-based editing/export)
- A brief summary of the content mapping decisions made
Card Design System
The visual cards follow a fixed editorial layout:
┌──────────────────────────────────────────┐ │ TOPIC LABEL SOURCE LABEL │ ← Top Bar ├────────────────────┬─────────────────────┤ │ English Title │ Thesis statement │ ← Title Area │ 中文标题 │ with key insight │ ├─────┬─────┬─────┬──┴──────────────────────┤ │ M │ P │ D │ G │ │ ← Framework Row (2-6 cards) ├─────┴─────┴─────┴─────┴──────────────────┤ │ ⚡ Dark Panel │ ★ Light Panel │ ← Two-Column Content │ (narrative/story) │ (numbered insights) │ ├──────────────────────────────────────────┤ │ Formula = M × P × D × G Closing note │ ← Highlight Bar ├──────────────────────────────────────────┤ │ FRAMEWORK LABEL BRAND NAME │ ← Footer └──────────────────────────────────────────┘
Color Palette
Default theme (customizable):
- Primary: Deep teal
#1a7a6d - Accent: Orange
#e8713a - Background: Warm gray
#f0ebe4 - Dark panel:
#1a1a1a
Typography
- English display: Playfair Display (serif)
- Chinese body: Noto Sans SC
- Monospace/labels: JetBrains Mono
Content Strategy
When generating cards from KB content:
- Extract or synthesize a framework - Identify the core structural model (2-6 components)
- Create a memorable acronym - Make the framework easy to remember
- Write a provocative thesis - Strong, opinionated claim in the title area
- Dark panel = narrative - Problems, transitions, paradigm shifts
- Light panel = insights - Actionable numbered takeaways (3-4 items)
- Bottom formula - Distill into one equation-style summary
Output Format
By default, generate both HTML and PNG:
- HTML file: Self-contained with embedded CSS, Google Fonts, and html2canvas for browser export
- PNG file: High-quality render at 1.5× scale (1800px wide), optimized for social media
Output location:
data/cards/YYYY-MM-DD-{topic-slug}/
Language Handling
CRITICAL: The card content language should match the source KB content language:
- If the KB chapter is in Chinese, generate Chinese card content
- If the KB chapter is in English, generate English card content
- Always include bilingual titles (English + Chinese) regardless of content language
- Technical terms and framework acronyms remain in their original language
Dependencies
The skill requires:
- Python 3.8+
- Playwright (for PNG rendering):
pip install playwright && playwright install chromium
Dependencies are checked and installed automatically on first run.

Example Usage
# Generate a card for a specific chapter python visual-card/_scripts/generate_card.py \ --chapter "data/books/markets-and-trading/market-structure-and-signals" # Generate with custom color scheme python visual-card/_scripts/generate_card.py \ --chapter "data/books/ai-and-research/model-training-and-optimization" \ --primary-color "#2d5a8c" \ --accent-color "#d4af37" # Generate HTML only (skip PNG) python visual-card/_scripts/generate_card.py \ --chapter "data/books/community-qa-and-discussion/platform-discussions" \ --html-only
Integration with Other Skills
This skill works best after:
- Synthesis: Content is already organized in the knowledge base
- Display: User has browsed the KB and identified interesting chapters
It can be chained with:
- Display: Generate cards for all chapters in a topic
- Feed: Create visual cards from feed items
Notes
- Cards are 1200px wide by default (poster format)
- PNG export uses device-scale-factor for high-DPI rendering
- The floating action button (FAB) in HTML allows browser-based export at multiple resolutions
- All cards include a copyright attribution to the original visual-note-card-skills project
