Figma Design Brief Skill
Converts a product requirement or feature request into a structured design brief — everything a designer needs to open Figma and start building confidently.
Required Inputs
- Feature or requirement (paste PRD snippet, ticket, or describe the feature)
- User goal (what is the user trying to accomplish?)
- Platform (iOS / Android / Web / Responsive / All)
- Existing components available (optional)
- Timeline (when does design need to be ready?)
Programmatic Helper
Contrast ratios cannot be eyeballed. The AA line sits at 4.5:1, and #777777
on white is 4.478 (fails) while #767676 is 4.54 (passes) — no amount of
looking at a screenshot separates those. Compute them:
npx --yes notugly fix "#8ab4f8" "#ffffff" # ratio, APCA, and the nearest passing colour
npx --yes notugly onepager <url> --out review.html # every pairing, printable
npx --yes notugly vision # which colours merge for colour-blind viewers
notugly fix returns the ratio, the APCA lightness contrast, and the closest
colour to the one already chosen that passes — same hue, same chroma. Paste
those numbers into the tables below rather than estimating them.
Deterministic, zero dependencies, and no model call — so it costs nothing to run and gives the same answer every time.
If the brief specifies colours, state the measured ratio for each intended text/background pairing. A brief that specifies an unreachable pairing wastes a design cycle before anybody notices.
Output Structure
1. Brief Header
Feature, PM, Designer, Platform, Design due, Dev handoff dates.
2. What We Are Designing and Why
- The goal: [One sentence — user problem being solved]
- Context: [2-3 sentences. Why now? What triggers this?]
