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 | $0.00102 | $0.00690 |
| Opus 5.5 | $0.00041 | $0.00276 |
| Sonnet 5.5 | $0.00020 | $0.00138 |
| Haiku 4.5 | $0.00010 | $0.00069 |
Grade A, and why
apply-aesthetic 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 12d 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 — 28 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill: Apply Aesthetic
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.
Choose and apply a design direction without breaking accessibility.
Steps
- Brief Inference first (mandatory). Before any tokens, name it: industry/domain, audience & tone, the one mood adjective the result must earn, motion depth, and the layout-family sequence (
${CLAUDE_SKILL_DIR}/../../../taste/design-taste.md→ Brief Inference + Variance Mandate). Generating before deciding = slop. - Pick a direction in
${CLAUDE_SKILL_DIR}/../../../taste/aesthetic-systems.md:- An archetype (recipe mapped to our tokens), or
- A named library system: browse with
python3 ${CLAUDE_SKILL_DIR}/../../../scripts/design_systems.py list(orsearch <term>/show <name>). Then runnode ${CLAUDE_SKILL_DIR}/../../../scripts/library.mjs get <name>and read theDESIGN.mdat the path it prints. An npm install carries the index and no spec, so this is what fetches it (checked against the sha256 the kit ships); where the spec is already on disk it fetches nothing. If it printsrefused, say the spec could not be fetched and pick from an archetype instead; never write a spec from memory.
- Apply the Library Contract (in
aesthetic-systems.md): re-pointsemantic.*tokens to the chosen system's color roles; map typography/spacing/radius/shadow/motion to${CLAUDE_SKILL_DIR}/../../../tokens/*.json. - Verify contrast of every mapped color pair (
${CLAUDE_SKILL_DIR}/../../../scripts/contrast.py/a11y-audit). A brand value that fails must be adjusted. Taste never overrides POUR. - Add motion per
${CLAUDE_SKILL_DIR}/../../../taste/motion-choreography.md; run the pre-flight aesthetic check indesign-taste.md.
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.

apply-aesthetic is a skill published in the GitHub repository plugin87/ux-ui-agent-skills (3,108 stars, last pushed 10d ago), licensed MIT. It adds 102 tokens to every session and 690 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.
