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 | $0.00071 | $0.01484 |
| Opus 5.5 | $0.00028 | $0.00594 |
| Sonnet 5.5 | $0.00014 | $0.00297 |
| Haiku 4.5 | $0.00007 | $0.00148 |
Grade A, and why
ui-ux-designer 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 today.
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.

UI/UX Designer & Design Systems Skill
Overview
This skill governs UI/UX design systems using the official Google Labs / Google Stitch DESIGN.md (google-labs-code/design.md) 2-layer specification. It maintains a single concise project-wide root DESIGN.md (<= 110 lines) alongside ultra-compact feature UI deltas (the ## Design section of the single discovery file docs/<feature-name>/spec.md, <= 30 lines) so visual tokens, WCAG 2.1 AA accessibility, and component states remain deterministic without 200-line per-feature boilerplate.
When to Use
Capability-Gated Trigger Rules
- INVOKE ONLY IF UI screens/components are created or modified AND root
DESIGN.mdis missing or new visual tokens, layouts, or screen states are introduced. - SKIP for backend/APIs, data pipelines, CLIs, SQL, refactors, or minor UI tweaks already covered by root
DESIGN.md. - Delegate Elsewhere: Backend/API contracts ->
senior-architect-engineering; production widget/CSS code ->code-implementerorflutter-implementer; automated UI/E2E runs ->qa-tester.
Process: The Standard design.md Lifecycle
- Inspect Root
DESIGN.md(<= 110 lines):- Check if root
DESIGN.md(or legacydesign.md/docs/design/) exists. - If missing: Author root
DESIGN.md(<= 110 lines) from references/design-md-template.md following the Google 2-layer spec:- Layer 1 (Machine-Readable YAML Frontmatter):
name,version,colors(primary,surface,text,error, etc.),typography(font_sans,font_mono,scale),rounded,spacing, andcomponentsusing{colors.primary}token references. - Layer 2 (8 Concise Sections):
## Overview,## Colors,## Typography,## Layout,## Elevation & Depth,## Shapes,## Components,## Do's and Don'ts.
- Layer 1 (Machine-Readable YAML Frontmatter):
- If present: Reuse existing tokens; append new global tokens/components in-place only when genuinely needed.
- Check if root
- Author Optional Feature UI Delta (
## Designindocs/<feature-name>/spec.md,<= 30 lines):- Fill
## DesignONLY when the feature introduces net-new screen layouts, user flows, or interactive states. Ifspec.mdis missing, create it from the 3-heading template (## Product,## Design,## Architecture); edit ONLY## Design. - Reference root
DESIGN.mdtokens ({colors.primary},{spacing.md}) directly—never duplicate full color/typography tables per feature.
- Fill
What ships with it
1 file 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.

ui-ux-designer is a skill published in the GitHub repository jggomez/expert-ai-developer-skills (30 stars, last pushed yesterday), licensed Apache-2.0. It adds 71 tokens to every session and 1,484 once invoked, about $0.0003 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 2026-11-06.
