npx @curdx/flow install --all to install frontend-designAnthropic's official skill (277k+ installs, 2026-03). It pushes Claude to make distinctive choices:
When the skill is available, it auto-activates in my workflow — design guidance is injected while generating UI.
Read:
.flow/CONTEXT.md — user's UI preferences
.flow/specs/<name>/requirements.md — UI-relevant US/AC
.flow/specs/<name>/design.md — UI component design (if any)
.flow/specs/<name>/research.md — design inspiration sources
Pay special attention to .flow/CONTEXT.md:
Confirm with the user:
Default: 2 HTML variants for fast iteration.
Skill: frontend-design
args: <description of the need>
The skill outputs UI code. I:
If the user wants 2-3 variants:
Variant A: "minimalist"
- Generous whitespace
- System font
- Single color
Variant B: "distinctive"
- Custom fonts (e.g. Space Grotesk + Inter)
- Intentional palette (e.g. warm neutrals + a single accent)
- Subtle animation
Variant C (optional): "dense"
- High information density
- Fits high-frequency users (e.g. admin UI)

# UI Design Decisions: <feature>
Generated: YYYY-MM-DD
## Variant A: Minimalist
- Font: system default (-apple-system, Segoe UI)
- Tone: white + light gray
- Rationale: fits products aiming for simplicity
- Trade-off: no visual memory hook
## Variant B: Distinctive
- Font: Space Grotesk (headings) + Inter (body)
- Tone: warm neutrals + #F59E0B accent
- Animation: submit button hover uses 200ms transform
- Rationale: branded feel, memorable
- Trade-off: must load external fonts
## Variant C: Dense
- Highest information density
- Completes all actions on one page
- Rationale: friendly to high-frequency users
- Trade-off: new users may feel overwhelmed
## Recommendation
- MVP → Variant B (brand feel + usability)
- If team resources are tight → Variant A
- For admin tools → Variant C
## Next Step
- After the user picks a variant → /curdx-flow:implement turns the HTML into production components

Next:
- Pick a variant → tell me which one → I'll turn it into production components
- Or the `browser-qa` skill to verify interactions in-browser (chrome-devtools)
The frontend-design skill makes "opinionated choices". I won't water them down because "someone might not like it".
A single option → hard for the user to decide. Two extremes + one middle ground → the user has a comparison.
Each sketch is a single HTML file, no build, double-clickable. Easy to share and iterate.
The sketch stage = HTML prototype. Convert to React/Vue/Svelte components only after a variant is chosen (that's /curdx-flow:implement's job).
Integrates with the frontend-design skill (Anthropic official). Falls back to Tailwind + shadcn defaults when unavailable.
