Canvas Design
A two-step design workflow: first articulate a design philosophy, then create visual designs on canvas. Based on the anthropics/skills canvas-design approach.
- Leverage native parallel subagent dispatch and 200k+ context windows where available.
When to Use This Skill
Use symptom -> action triggers: when one matches, apply this skill and verify with the protocol below.
- 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
## 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
## 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
| Principle | Description |
|-----------|-------------|
| **Intentionality** | Every element exists for a reason |
| **Hierarchy** | Guide the eye through deliberate contrast and spacing |
| **Consistency** | Repeated patterns build trust and comprehension |
| **Restraint** | Fewer elements, each carrying more weight |
| **Craftsmanship** | Pixel-perfect alignment, harmonious proportions |
### 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

## Cross-Client Portability
This skill is written to stay usable across GitHub Copilot, Claude Code, and Codex.
- GitHub Copilot: keep the folder in a Copilot-visible skill path or wrap the
workflow in project instructions when folder discovery is unavailable.
- Claude Code: keep the folder in a local skills directory or a compatible plugin source.
- Codex: install or sync the folder into
`$CODEX_HOME/skills/canvas-design` and restart Codex after major changes.

## MCP Availability And Fallback
Preferred MCP Server: None required
- Fallback prompt: "Use the Canvas Design skill without MCP. Rely on its local instructions, bundled resources, standard shell or editor tools, and direct verification. Show the evidence used before concluding."
- Do not claim an MCP operation was used when the active host does not expose it.
- Treat local files, tests, rendered outputs, logs, or screenshots as the fallback evidence path.
<!-- MCP:END -->
## Anti-Patterns
- Starting from a generic template without adapting it: The output may look polished but still miss the real audience or medium.
- Ignoring final render or export review: Layout bugs often appear only after the asset is opened in its destination tool.
- Fixing content and presentation in one pass: It becomes hard to tell whether a problem is structural or visual.
## Verification Protocol
Before claiming "skill applied successfully":
1. Pass/fail: The Canvas Design implementation names the target runtime, framework version, and affected files.
2. Pass/fail: Build, lint, test, or equivalent local validation is run for the changed surface.
3. Pass/fail: Edge cases for errors, dependency drift, and environment differences are addressed or explicitly out of scope.
4. Pressure-test scenario: Apply the workflow to a change that passes happy-path tests but fails one boundary condition.
5. Success metric: Zero untested success claims; every implementation claim maps to a command or artifact.
### 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
