design-handoff

design-handoff is a skill for Claude Code, Codex from getcrew44/crew44. It costs 36 tokens per session (598 once invoked), scanned A, original, MIT.

A design-to-development handoff guide that turns a finished interface design into detailed build instructions. It covers layout, design tokens (named style values), states, mobile behavior, unusual cases, animation, and accessibility.

In plain words
What is it for?
Use it to document screens and components before coding. It helps specify responsive layouts, reusable styles, interaction states, edge cases, and accessibility requirements.
Why use it?
It prevents developers from having to guess how the design should behave. Missing details such as loading, error, or keyboard states can otherwise become inconsistent or turn into bugs.

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 6d 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.

Design Handoff

Produce a spec that lets the Coding Agent build the design without guessing. If it isn't specified, they'll have to invent — and they'll invent inconsistently.

Principles

  • Tokens, not values. Reference --space-4 or color-primary-600, not 16px or #2563eb. If a value isn't in the system, flag that as a token gap, not a one-off.
  • Show every state. Default, hover, active, focus, disabled, loading, error, empty, success. A state you skip becomes a bug.
  • Explain the why. "This collapses to a sheet on mobile because the action is one-handed" helps the engineer make sensible judgment calls when reality diverges from the spec.
  • Specify edges, not just the happy path. Long text, no text, slow connection, partial data — pin the behavior.

Sections the spec must cover

  1. Overview. What this screen or component does, who uses it, and the user state when they encounter it.
  2. Layout. Grid, breakpoints, responsive behavior at each breakpoint. Where things move, hide, or change order.
  3. Tokens used. Color, typography, spacing, radius, shadow — listed with their token names and where they apply.
  4. Components. Each component named, with variants, props that matter for behavior, and any composition rules.
  5. States and interactions. Per element, the full state list with the visual change and trigger.
  6. Responsive behavior. What changes at each breakpoint. Not just "stacks on mobile" — what gets prioritized, what gets cut.
  7. Edge cases. Long copy, empty data, zero results, max items, slow connection, error states. The expected behavior for each.
  8. Motion. Per animated element: trigger, what moves, duration, easing. Honor prefers-reduced-motion.
  9. Accessibility. Focus order, ARIA labels and roles, keyboard interactions, screen reader announcements, contrast confirmations.

Common spec gaps that cause rework

  • Loading and error states for async content.
  • What happens when content overflows (truncate? wrap? scroll?).
  • Empty state for collections that start empty.
  • Behavior under slow or failed network.
  • Keyboard shortcuts and tab order through complex layouts.
  • Animation choreography across linked elements.

What this file has done since we first saw it

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.

design-handoff is a skill published in the GitHub repository getcrew44/crew44 (359 stars, last pushed 2mo ago), licensed MIT. It adds 36 tokens to every session and 598 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
