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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00040 | $0.02118 |
| Opus 5 | $0.00020 | $0.01059 |
| Sonnet 5 | $0.00008 | $0.00424 |
| Haiku 4.5 | $0.00004 | $0.00212 |
Grade A, and why
stitch-ued-guide 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 5d 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 — 178 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Stitch UED Guide
This is a reference guide, not an action skill. Use it when:
- You need specific design terminology for a Stitch prompt (masonry, glassmorphism, split-screen)
- You're unsure how to describe a layout pattern or visual style
- You want to apply color + theme structure consistently
- You need to know device-specific constraints for prompt writing
Prompt engineering strategy
The most effective Stitch prompts follow this 4-part structure:
[Context & Style] + [Layout Structure] + [Component Details] + [Content & Data]
Context & Style:
"Mobile fitness app for gym-goers. Dark mode with neon green accents. Cyberpunk aesthetic. Rounded corners."
Layout Structure:
"Bottom navigation bar (Home, Workout, Progress, Profile). Scrollable main feed. Sticky top bar with greeting."
Component Details:
"Workout cards with gradient border, thumbnail, title, duration badge, and 'Start' pill button."
Content & Data:
"Sample data: 'Upper Body Blast' (45 min), 'Core Destroyer' (20 min), 'Morning Run' (30 min, completed today)."
Stitch model selection
| Model | When to use |
|---|---|
GEMINI_3_1_PRO |
High-fidelity designs, complex layouts, when quality matters — recommended default |
GEMINI_3_FLASH |
Fast iteration, wireframes, rapid exploration, when speed matters |
GEMINI_3_PRO |
Deprecated — still works but will be removed. Use GEMINI_3_1_PRO instead |
Color variant reference (colorVariant)
Controls how Stitch derives the full color palette from your primaryColor:
| colorVariant | Visual effect | Best for |
|---|---|---|
MONOCHROME |
Single-hue, editorial feel | Luxury, minimal, text-heavy, portfolios |
NEUTRAL |
Subdued, professional | Corporate, enterprise, medical |
TONAL_SPOT |
Balanced accent spots on neutral base | SaaS, productivity, dashboards |
VIBRANT |
Bold, energetic colors | Consumer apps, social, food |
EXPRESSIVE |
Multicolor, dynamic | Creative, gaming, entertainment |
FIDELITY |
Precise brand color matching | Brand-heavy, marketing, landing pages |
CONTENT |
Palette adapts to content | Media, editorial, photo-heavy |
RAINBOW |
Full spectrum | Kids apps, events, playful |
FRUIT_SALAD |
Warm multicolor | Food, lifestyle, wellness |
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-ued-guide is a skill published in the GitHub repository gabelul/stitch-kit (43 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 40 tokens to every session and 2,118 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.
