design-handoff

design-handoff is a skill for Claude Code from nota-america/forgecat-agent-profiles. It costs 49 tokens per session (965 once invoked), scanned A, a copy of design-handoff, Apache-2.0.

A specification that explains how to build a design in code. It records measurements, colours, typography, responsive behaviour, component states, interactions, edge cases, and accessibility details.

In plain words
What is it for?
Use it to prepare developer handoff documents from a design, including layout rules, design tokens, props, breakpoints, animations, keyboard behaviour, and screen reader requirements.
Why use it?
It reduces ambiguity between designers and developers, especially around what happens on different screen sizes, during loading or errors, and when users interact with components.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

design-handoff scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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

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

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
