Hot #2670 First seen Feb 19, 2026

Installation

$ npx skills add 2ykwang/agent-skills --skill html-visual

Summary

  • Generate an interactive single-file HTML visualization — mockup, wireframe, ERD, flowchart, chart, slides, architecture diagram, dashboard, timeline, mindmap, kanban, or table.
  • Use when the user wants something rendered rather than described: a UI mockup or wireframe, a database schema as an ERD, business logic as a flowchart, data as a chart, or content as slides.
  • Also use when they point at a file (schema, spec, data) and ask to see it visualized.

HTML Visualization

Input

$ARGUMENTS

Instructions

Visualize the user's request as an interactive single HTML file. First, read references/common-rules.md to review common rules.

Type Determination

Determine the type from the first word of $ARGUMENTS.

Argument Type Filename Pattern
mockup UI mockup (high-fidelity) mockup-{name}.html
wireframe Wireframe (low-fidelity, hand-drawn style) wireframe-{name}.html
erd ERD erd-{name}.html
flow Flowchart / Sequence diagram flow-{name}.html
chart Data chart chart-{name}.html
slides Presentation slides-{name}.html
arch Architecture diagram arch-{name}.html
dashboard Composite dashboard dashboard-{name}.html
timeline Timeline / Gantt chart timeline-{name}.html
mindmap Mindmap mindmap-{name}.html
kanban Kanban board kanban-{name}.html
table Interactive data table table-{name}.html

No match: Infer the type from the request content. If unable to infer, ask the user. When inferred, use visual-{name}.html as the filename.

{name} rule: Extract the core noun from the request and convert to kebab-case. e.g., "user login form" → login-form, "payment flow" → payment-flow.

Input Handling

  • File path provided: Read and analyze the file, then visualize.

e.g., /html-visual erd schema.prisma → Analyze the Prisma schema to auto-generate ERD

  • Existing HTML modification: Read and modify the existing file. Do not recreate from scratch.
  • Natural language only: Infer the type, then generate.

Context Gathering

  • Description is sufficient: Generate immediately (e.g., "simple login form mockup")
  • Project code reference needed: Read code/schema/API first (e.g., "our project's ERD", "current payment flow")
  • Criterion: If the request contains project context references like "our", "current", "project's", read the code first.

Type-Specific Guides

mockup

  • Device frame: Actual device frame shape for mobile/tablet UI
  • Multiple screens: Side-by-side layout + screen labels
  • Placeholder data: Realistic data matching project context
  • Tab/swipe for screen transitions

wireframe

  • Hand-drawn (sketch) style: Slightly irregular lines, hand-drawn feel
  • Black-and-white or grayscale. Minimal color
  • Text areas shown as gray blocks (no "Lorem ipsum")
  • Focus on layout and information structure, exclude visual details

erd

  • Entity boxes with attribute lists. Distinguish PK/FK
  • Relationship lines: 1:1, 1:N, N:M notation. Auto-track on node drag
  • Include relationship type legend

flow

  • Node types: Start/End (circle), Process (rectangle), Decision (diamond)
  • Directional arrows. Auto-track on node drag
  • Display branch conditions on connection lines

chart

  • Auto-select appropriate chart type for the data (bar, line, pie, scatter, etc.)
  • Axis labels + units, hover tooltips, legend
  • Use Chart.js or D3.js

slides

  • Reveal.js CDN-based
  • Slide transition animations
  • Code block highlighting (highlight.js)
  • Speaker notes support (toggle with S key)

arch

  • Separate system components by layer/zone (Frontend / Backend / DB / External)
  • Label communication lines with protocols (HTTP, gRPC, pub/sub, etc.)
  • Zoom/pan support
  • D3.js force-directed or direct SVG generation

dashboard

  • Arrange multiple charts/metrics in grid layout
  • KPI cards at the top (numbers + change rates)
  • Cross-chart interaction: Click one → filter others

timeline

  • Horizontal or vertical timeline
  • Event nodes + date labels
  • Zoom/scroll for period navigation
  • Use Mermaid gantt or D3.js

mindmap

  • Radial expansion from center node
  • Node collapse/expand
  • Use Mermaid mindmap or direct SVG generation

kanban

  • Columns: TODO / In Progress / Done (customizable)
  • Drag and drop cards between columns
  • Display labels/tags on cards

table

  • Sort by clicking column headers (ascending/descending)
  • Search/filter at the top
  • Pagination or virtual scroll
  • Cell highlight, row selection

Procedure

  1. Identify type + target. Ask if ambiguous. Read the file if a path is provided.
  2. Context gathering decision. Determine if project context is needed. If so, read relevant code/docs.
  3. Read references/common-rules.md. Review common principles, aesthetics, CDN, and error prevention rules.
  4. Read references/html-boilerplate.md. Start from the base HTML template.
  5. Generate HTML following the type-specific guide.
  6. Validate: Review the generated HTML.

- No smart quotes (curly quotes) in HTML attributes - No unclosed tags - No overlapping nodes/elements - If issues found, fix and re-validate

  1. Instruct to open {filename}.
