Don’t assume — If it’s not specified, the developer will guess. Specify everything.
Use tokens, not values — Reference spacing-md not 16px.
Show all states — Default, hover, active, disabled, loading, error, empty.
Describe the why — “This collapses on mobile because users primarily use one-handed” helps developers make good judgment calls.

| Mobile (<768px) | [What changes] |

### Edge Cases
- **Empty state**: [What to show when no data]
- **Long text**: [Truncation rules]
- **Loading**: [Skeleton or spinner]
- **Error**: [Error state appearance]

### Animation / Motion
| Element | Trigger | Animation | Duration | Easing |
|---------|---------|-----------|----------|--------|
| [Element] | [Trigger] | [Description] | [ms] | [easing] |

### Accessibility Notes
- [Focus order]

If Connectors Available

If ~~design tool is connected:

Pull exact measurements, tokens, and component specs from Figma
Export assets and generate a complete spec sheet

If ~~project tracker is connected:

Link the handoff to the implementation ticket
Create sub-tasks for each section of the spec

Tips

Share the Figma link — I can pull exact measurements, tokens, and component info.
Mention edge cases — “What happens with 100 items?” helps me spec boundary conditions.
Specify the tech stack — “We use React + Tailwind” helps me give relevant implementation notes.

About this skill

Trigger

Generate developer handoff specs from a design. Use when a design is ready for engineering and needs a spec sheet covering layout, design tokens, component props, interaction states, responsive breakpoints, edge cases, and animation details.

The verbatim description from this skill’s front matter — the string an agent matches on to decide whether to load it.

Colophon

How this issue was made

Source

github.com/anthropics/knowledge-work-plugins, branch main, last pushed 23 September 2026.

Licence

Apache-2.0 — the text of every skill is reproduced unmodified, frontmatter included, under the upstream licence.

Discovery

200 skills found by walking the repository tree for SKILL.md, not by matching a directory convention. 27 distinct layouts observed: bio-research/skills/*/SKILL.md, cowork-plugin-management/skills/*/SKILL.md, customer-support/skills/*/SKILL.md, data/skills/*/SKILL.md, design/skills/*/SKILL.md, engineering/skills/*/SKILL.md, enterprise-search/skills/*/SKILL.md, finance/skills/*/SKILL.md, human-resources/skills/*/SKILL.md, legal/skills/*/SKILL.md, marketing/skills/*/SKILL.md, operations/skills/*/SKILL.md, partner-built/apollo/skills/*/SKILL.md, partner-built/brand-voice/skills/*/SKILL.md, partner-built/common-room/skills/*/SKILL.md, partner-built/slack/skills/*/SKILL.md, partner-built/zoom-plugin/skills/*/SKILL.md, partner-built/zoom-plugin/skills/contact-center/*/SKILL.md, partner-built/zoom-plugin/skills/meeting-sdk/*/SKILL.md, partner-built/zoom-plugin/skills/meeting-sdk/web/*/SKILL.md, partner-built/zoom-plugin/skills/video-sdk/*/SKILL.md, partner-built/zoom-plugin/skills/virtual-agent/*/SKILL.md, partner-built/zoom-plugin/skills/zoom-mcp/*/SKILL.md, pdf-viewer/skills/*/SKILL.md, product-management/skills/*/SKILL.md, productivity/skills/*/SKILL.md, sales/skills/*/SKILL.md.

Issue colours

Resolved from the awesome-design-md registry — hue 39°, chroma 0.113. Two accent tones are generated per issue and each is proven against its own ground before it ships: a single accent that passes AA on both light and dark paper is arithmetically impossible.

Typefaces

Display: Copernicus is not available to us; set in Newsreader.

We never load a typeface at request time from a third-party origin, so a brand face we do not already self-host is substituted rather than fetched.

Heading repairs

1 repair applied to this skill so the document has one h1 and no skipped levels:

Removed “/design-handoff”, a leading h1 that duplicated the skill title.

Spec compliance

53 editorial notes across 41 of 200 skills. They are printed in the margin of each skill rather than as errors here.

and 31 more.

Images

Images inside a skill come from the upstream repository. Where the author gave no alternative text we mark the image decorative rather than inventing a description — a plausible caption we made up is worse than none for the reader who depends on it.

Marketplace

A plugin manifest is published at .claude-plugin/marketplace.json by Anthropic, declaring 120 plugins. It is read for editorial metadata only — never as the skill index, which is always the repository tree.

Signal

Install counts come from skills.sh. They measure downloads, not quality, and an unranked repository is not an unread one.

Agent surfaces

The whole issue is available as one markdown document at /anthropics/knowledge-work-plugins.md, and each skill at its own .md URL.

Publication

Set by Skills Docs from the source repository. Body text is Literata at the reader’s chosen size and measure; code is Geist Mono. Nothing on this page was written by us except this paragraph.

If you see unfamiliar placeholders or need to check which tools are connected, see CONNECTORS.md (opens in a new tab).

Generate comprehensive developer handoff documentation from a design.

Usage

/design-handoff $ARGUMENTS

Generate handoff specs for: @$1

If a Figma URL is provided, pull the design from Figma. Otherwise, work from the provided description or screenshot.

What to Include

Visual Specifications

Exact measurements (padding, margins, widths)
Design token references (colors, typography, spacing)
Responsive breakpoints and behavior
Component variants and states

Interaction Specifications

Click/tap behavior
Hover states
Transitions and animations (duration, easing)
Gesture support (swipe, pinch, long-press)

Content Specifications

Character limits
Truncation behavior
Empty states
Loading states
Error states

Edge Cases

Minimum/maximum content
International text (longer strings)
Slow connections
Missing data

Accessibility

Focus order
ARIA labels and roles
Keyboard interactions
Screen reader announcements

Principles

Don’t assume — If it’s not specified, the developer will guess. Specify everything.
Use tokens, not values — Reference spacing-md not 16px.
Show all states — Default, hover, active, disabled, loading, error, empty.
Describe the why — “This collapses on mobile because users primarily use one-handed” helps developers make good judgment calls.
