UX/UI Agent Skills is a set of instructions, design tokens, reusable components, accessibility rules, and design-system references that guide Claude in producing interface designs and code. It is intended for developers and designers who want framework-independent, token-based UI work with accessibility checks. The catalogue entries package these UX, UI, component, and validation workflows as Claude Code skills and related add-ons.
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.

What it costs to keep this loaded
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 | $0.00092 | $0.00576 |
| Opus 5.5 | $0.00037 | $0.00230 |
| Sonnet 5.5 | $0.00018 | $0.00115 |
| Haiku 4.5 | $0.00009 | $0.00058 |
Grade A, and why
design-tokens 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.

What it actually says
Skill: Design Tokens
Step 0: is the kit here? This skill reads files from the kit. Check once:
ls ${CLAUDE_SKILL_DIR}/../../../tokens >/dev/null 2>&1 && echo KIT_OK || echo KIT_MISSINGOnKIT_MISSINGonly the skill folders were installed, which is whatnpx skills adddoes. Say so plainly, point the user atnpx ux-ui-agent-skills initor the plugin install, and stop. Do not guess the contents of a file you could not open.
Produce and maintain DTCG ($type/$value) tokens following the project's 3-tier system.
Steps
- Read
${CLAUDE_SKILL_DIR}/../../../.claude/rules/tokens-and-color.md→ "Token System" + "Color Guidelines" and${CLAUDE_SKILL_DIR}/../../../.claude/rules/typography-and-spacing.mdfor the rules (4px base, Major Third scale, OKLCH palette generation, dark-mode-at-semantic-layer). - Read the relevant existing files in
${CLAUDE_SKILL_DIR}/../../../tokens/to match structure:colors.json,typography.json,spacing.json,shadows.json,borders.json,breakpoints.json,motion.json,gradients.json,opacity.json,blur.json,sizing.json,states.json,theming.json. - Generate/extend tokens:
- Primitives = raw values (never used directly). Semantic = purpose aliases. Component = component-scoped.
- New palettes: generate 11 OKLCH shades; verify 500 ≥ 4.5:1 on white (text), 600 ≥ 3:1 (UI) using the
a11y-auditskill /${CLAUDE_SKILL_DIR}/../../../scripts/contrast.py. - Multi-brand/density →
theming.json.
- Validate: run
python3 ${CLAUDE_SKILL_DIR}/../../../scripts/validate_tokens.py(JSON validity + alias resolution).
Output
DTCG JSON. Preserve $description on every token. Reference, never hardcode.
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-tokens is a skill published in the GitHub repository plugin87/ux-ui-agent-skills (3,006 stars, last pushed today), licensed MIT. It adds 92 tokens to every session and 576 once invoked, about $0.0004 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 2026-08-30.

accessibility
Audit and improve web accessibility following WCAG 2.2 guidelines. Use when asked to "improve accessibility", "a11y audit", "WCAG compliance", "screen reader support", "keyboard navigation", or "make accessible".
component-family-consistency
Buttons, inputs, badges and pills share radius, colour logic, shadow, border and spacing. Use when building or reviewing a component library.
modular-scale-typography
Ratio-based type scale where every size relates to the others. Use when defining font sizes or type tokens, or when typography feels arbitrary.

View modes, row selection, mass actions, sorting, filters, search and table patterns. Use when designing data tables, listings, file browsers or any collection.
information-architecture
Naming, navigation, a UI that mirrors the data model, confirms for irreversible changes. Use when structuring a large application or naming its entities.
