canvas-design（画布设计）

Skill Paths

• Workspace skills: .github/skills/
• Global skills: C:/Users/LOQ/.codex/skills/ for Codex or C:/Users/LOQ/.agents/skills/ for the shared mirror

A two-step design workflow: first articulate a design philosophy, then create visual designs on canvas. Based on the anthropics/skills canvas-design approach.

When to Use This Skill

• Creating design philosophy documents (.md)
• Generating visual canvas designs (.png/.pdf)
• Articulating design principles and aesthetic rationale
• Crafting multi-page design documents
• Exploring design thinking and intentional visual communication

Step 1: Design Philosophy Document

Create a markdown document that articulates the design philosophy before any visual creation.

Philosophy Document Structure

## Skill Paths

- Workspace skills: `.github/skills/`
- Global skills: `C:/Users/LOQ/.codex/skills/` for Codex or `C:/Users/LOQ/.agents/skills/` for the shared mirror

## Core Intent
What is this design trying to communicate? What feeling should it evoke?

## Guiding Principles
1. **[Principle Name]** — Explanation of how this shapes decisions
2. **[Principle Name]** — Explanation
3. **[Principle Name]** — Explanation

## Aesthetic Direction
- **Color Philosophy**: Why these colors, what they represent
- **Typography Philosophy**: What the type choices communicate
- **Spatial Philosophy**: How whitespace and layout serve the intent
- **Material/Texture**: Physical or digital texture decisions

## Inspirations & References
- [Reference 1]: What specifically resonates and why
- [Reference 2]: The element to borrow vs. what to avoid

## Anti-Patterns
- What this design explicitly avoids and why

Philosophy Examples

Minimalist App Design:

"Every element must earn its place. If removing something doesn't hurt the experience, it shouldn't exist. Whitespace is not empty — it's breathing room for the content that matters."

Warm Community Platform:

"Design should feel like a well-lit kitchen — inviting, warm, organized but not sterile. Rounded corners, warm neutrals, and generous spacing signal 'you belong here.'"

Technical Documentation:

"Clarity is kindness. Dense information needs generous hierarchy, consistent patterns, and visual anchors. The reader should never wonder where they are."

Step 2: Canvas Creation

After establishing the philosophy, create visual designs that embody those principles.

Canvas Workflow

1. Review philosophy — Reread the design philosophy document
2. Define canvas — Set dimensions, background, grid system
3. Establish hierarchy — Place primary elements first
4. Apply philosophy — Every decision references a stated principle
5. Refine — Remove anything that doesn't serve the core intent

Essential Design Principles

Multi-Page Documents

For multi-page designs:

• Maintain consistent margins and grid across pages
• Use a master color palette derived from the philosophy
• Create a visual rhythm — varying density to prevent monotony
• Include breathing pages (minimal content) between dense sections

Quality Checklist

• Every element traces back to a stated principle
• Color choices align with the documented philosophy
• Typography serves the content hierarchy
• Whitespace is intentional, not leftover
• The design could be explained purely through its philosophy doc
• Nothing decorative exists without purpose

Craftsmanship Emphasis

Design is a craft. The difference between good and great design:

• Alignment: Not "close enough" but mathematically precise
• Spacing: Consistent rhythm using a base unit (4px, 8px)
• Color: Not just "looks nice" but optically balanced, accessible (WCAG AA+)
• Typography: Line height, letter spacing, and measure all tuned for readability
• Details: Transitions, hover states, focus indicators — the invisible work

"The details are not the details. They make the design." — Charles Eames

<!-- PORTABILITY:START -->
## Cross-Client Portability

This skill is written to stay usable across GitHub Copilot, Claude Code, Codex, and Gemini CLI.

- GitHub Copilot: keep the folder in a Copilot-visible skill or plugin path, or wrap the workflow as project instructions if the host does not support portable skill folders directly.
- Claude Code: keep the folder in a local skills directory or a compatible plugin or marketplace source.
- Codex: install or sync the folder into `$CODEX_HOME/skills/<skill-name>` and restart Codex after major changes.
- Gemini CLI: this repository generates a project command named `/skills:canvas-design` from this skill. Rebuild commands with `python scripts/export-gemini-skill.py canvas-design` and then run `/commands reload` inside Gemini CLI.

<!-- MCP:START -->
## MCP Availability And Fallback

No dedicated MCP server is required for the normal workflow in this skill.

- If the current host lacks an equivalent tool surface, use the bundled scripts, standard shell or editor tooling, and the manual workflow already described in this skill.
- Treat local verification as the fallback evidence path before closing the task.
