Generate structured developer handoff annotations

Figma Annotation Guide Skill

Produces a complete set of developer handoff annotations for a Figma screen or component — the notes that turn a visual design into a buildable spec.

Required Inputs

• Screen or component description (describe or summarise what was designed)
• Platform (iOS / Android / Web / React Native)
• Interaction type (static / interactive / animated / form)
• Developer audience (mobile / frontend / full-stack)

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.

Contrast annotations should carry the computed ratio and the target, e.g. "4.52:1 — passes AA for body text". An annotation that says "check contrast" is a task, not an annotation.

Output Structure

1. Screen/Component Overview

Name, purpose, entry points, exit points.

2. Interaction Annotations

[Element name]

• Default state: [Visual description]
• On tap/click: [Exact action — API call, state change, navigation]
• Loading state: [Description]
• Success state: [What happens after]
• Error state: [What error looks like and user options]
• Disabled condition: [When and why]

3. State Inventory

Element	States Required
[Element]	Default, Hover, Active, Disabled, Loading, Error, Empty

Flag missing designs: "Warning: Error state not designed — needed before build"

4. Spacing and Layout Notes

Fixed vs fluid elements, scroll behaviour, breakpoints, safe areas.

5. Content and Copy Rules

Character limits, dynamic vs static content, truncation rules, empty states.

6. Accessibility Annotations

Touch targets, screen reader labels, focus order, colour contrast, motion preferences.

7. Edge Cases and Developer Questions

• [Unresolved question for developer to flag]

Quality Checks

• Every interactive element has all states defined
• State inventory flags missing designs
• Accessibility covers touch targets and screen reader labels
• Empty states specified
• Edge cases listed as actionable questions

Anti-Patterns

• Do not annotate only the happy path — error states, loading states, and empty states must all be documented
• Do not use vague spacing descriptions like "some padding" — specify exact pixel values or token names
• Do not skip accessibility annotations — focus order, ARIA labels, and colour contrast ratios must be included
• Do not leave interaction behaviour undescribed — every interactive element needs a documented response
• Do not produce annotations without edge cases — developers need to know what happens at boundaries

Example Trigger Phrases

• "Write dev annotations for this Figma screen"
• "Create developer handoff notes for [screen/component]"
• "Document this design for the engineering team"
• "Write the Figma spec for [feature]"
• "What should I annotate before handing off this design?"
