Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00049 | $0.00941 |
| Opus 5.5 | $0.00020 | $0.00376 |
| Sonnet 5.5 | $0.00010 | $0.00188 |
| Haiku 4.5 | $0.00005 | $0.00094 |
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 13d 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.
This is a copy
100% identical to design-handoff — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts

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-mdnot16px. - 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.

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 sun2443/designer-skills (0 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 49 tokens to every session and 941 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to design-handoff, differing in 0 lines, and is treated as a copy.
