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 | $0.00040 | $0.02399 |
| Opus 5 | $0.00020 | $0.01200 |
| Sonnet 5 | $0.00008 | $0.00480 |
| Haiku 4.5 | $0.00004 | $0.00240 |
Grade A, and why
stitch-ui-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 3d 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.

Stitch UI Design Prompting
Expert guidance for crafting effective prompts in Google Stitch, the AI-powered UI design tool by Google Labs. This skill helps create precise, actionable prompts that generate high-quality UI designs for web and mobile applications.
What is Google Stitch?
Google Stitch is an experimental AI UI generator powered by Gemini 2.5 Flash that transforms text prompts and visual references into functional UI designs. It supports:
- Text-to-UI generation from natural language prompts
- Image-to-UI conversion from sketches, wireframes, or screenshots
- Multi-screen app flows and responsive layouts
- Export to HTML/CSS, Figma, and code
- Iterative refinement with variants and annotations
Core Prompting Principles
1. Be Specific and Detailed
Generic prompts yield generic results. Specific prompts with clear requirements produce tailored, professional designs.
Poor prompt:
Create a dashboard
Effective prompt:
Member dashboard with course modules grid, progress tracking bar,
and community feed sidebar using purple theme and card-based layout
Why it works: Specifies components (modules, progress, feed), layout structure (grid, sidebar), visual style (purple theme, cards), and context (member dashboard).
2. Define Visual Style and Theme
Always include color schemes, design aesthetics, and visual direction to avoid generic AI outputs.
Components to specify:
- Color palette (primary colors, accent colors)
- Design style (minimalist, modern, playful, professional, glassmorphic)
- Typography preferences (if any)
- Spacing and density (compact, spacious, balanced)
Example:
E-commerce product page with hero image gallery, add-to-cart CTA,
reviews section, and related products carousel. Use clean minimalist
design with sage green accents and generous white space.
3. Structure Multi-Screen Flows Clearly
For apps with multiple screens, list each screen as bullet points before generation.
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.

stitch-ui-design is a skill published in the GitHub repository beel-collab/presets.dev (2 stars, last pushed 4mo ago), licensed MIT. It adds 40 tokens to every session and 2,399 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 2026-09-03.
