Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00055 | $0.01206 |
| Opus 5.5 | $0.00022 | $0.00482 |
| Sonnet 5.5 | $0.00011 | $0.00241 |
| Haiku 4.5 | $0.00006 | $0.00121 |
Grade A, and why
design 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Design - UI/UX Implementation
Create interfaces that feel intuitive, responsive, and delightful. Focus on the small details that distinguish polished apps from mediocre ones.
When to Use This Skill
- Implementing new screens or components
- Reviewing UI code for UX issues
- Deciding between loading state patterns
- Placing buttons, CTAs, and interactive elements
- Handling errors and edge cases gracefully
- Adding animations and transitions
- Choosing animation timing and curves
The Golden Rules
- Thumb-first design - Primary actions in the bottom 2/3 of the screen
- Immediate feedback - Every tap/action should have visible response
- Smart defaults - Auto-focus, pre-fill, remember preferences
- Graceful failures - Errors should guide, not blame
- Platform respect - iOS swipe-back, Android gestures, Material patterns
- Purposeful motion - Animate to communicate, not to impress
Core Principles
Every Action Deserves Feedback
Users should never wonder "did that work?" - provide visual press states, haptics, loading indicators, and success/error messages. See interaction-guide.md for details.
Auto-Focus Intelligence
Focus the right field at the right time - login screens should auto-focus email, search screens should auto-focus the search field. See interaction-guide.md for the complete decision table.
Error Recovery, Not Error Display
Errors should help users succeed. Instead of "Error: Invalid input", show "Email needs an @ symbol". See visual-guide.md for error state patterns.
Touch Targets
Minimum 48×48dp for all interactive elements. See interaction-guide.md for sizing guidelines.
Purposeful Animation
Animation should communicate change, not decorate. Use 300ms for transitions, match curves to motion direction, and always respect reduced motion preferences. See animation-guide.md for timing, curves, and patterns.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 is a skill published in the GitHub repository launch52-ai/flutter-template (2 stars, last pushed 7mo ago), licensed MIT. It adds 55 tokens to every session and 1,206 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-31.
