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.

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 | $0.00039 | $0.01098 |
| Opus 5.5 | $0.00016 | $0.00439 |
| Sonnet 5.5 | $0.00008 | $0.00220 |
| Haiku 4.5 | $0.00004 | $0.00110 |
Grade A, and why
scaffold-project 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 10d 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.
What it actually says
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.
Generate a new design-project skeleton from ${CLAUDE_SKILL_DIR}/../../../templates/product-design/ into a target directory the user names.
The layout to produce (exactly the reference structure):
<target>/
# CONTEXT CLAUDE LOADS
CLAUDE.md the brief Claude reads every session
CLAUDE.local.md your personal prefs, gitignored
.mcp.json Figma, Notion, Drive connections
# TEAM TOOLKIT
.claude/
rules/ conventions, loaded only when relevant
skills/ repeatable workflows, off main context
commands/ your custom slash commands
settings.json shared permissions, checked into git
# YOUR PROJECT
design-tokens.json source of truth: color, type, spacing
src/components/ the real UI Claude reads and edits
public/images/ real images so prototypes don't break
reference/ real screens Claude studies for context
The fast path, when the kit is installed or reachable via npx:
npx ux-ui-agent-skills new <target>
That does steps 2 and 3 below in one call (template copied, CLAUDE.local.md
un-suffixed, engine areas installed without overwriting the lean brief). Then pick
up at step 4. The manual steps are spelled out so the same result can be produced
by hand from a clone.
Steps:
-
Ask for the target directory if not given. Create it if it does not exist.
-
Copy every file of
${CLAUDE_SKILL_DIR}/../../../templates/product-design/into it, preserving the tree. Two rules on the copy:CLAUDE.local.md.templatelands asCLAUDE.local.md(the suffix exists only so the kit's own gitignore cannot swallow the file)..gitkeepstays in.claude/skills/,.claude/commands/,src/components/,public/images/, andreference/so the empty folders survive the first commit. The template already ships.gitignore(which ignoresCLAUDE.local.md),.mcp.json,.claude/settings.json, and three rules files (components.md,tokens.md,accessibility.md).
-
Install the engine next to it so the gates the brief references actually run:
npx ux-ui-agent-skills add tokens components taste accessibility \ workflows content frameworks design-systems scripts skillsUse
add, notinit:initalso writes the full engineCLAUDE.mdover the lean project brief. The project brief stays short by design, and the engine knowledge loads from the copied folders when a task needs it. -
Install the render gates' one dependency in the target:
npm i -D playwright. Skipping this is silent: every render gate printsSKIPPEDand exits 0. -
Fill in the placeholders in
CLAUDE.mdwith the user: product, primary user, stack, icon set, vocabulary. Leave nothing in angle brackets behind. -
Point
design-tokens.jsonat the brand: replace theprimitive.brandramp, keep the semantic and component tiers, then prove it still passes:python3 ${CLAUDE_SKILL_DIR}/../../../scripts/validate_contrast.py -
Remind the user to fill
reference/with real screens andpublic/images/with real imagery, and to set the MCP env vars (FIGMA_API_KEY, ...) in their own shell. Never write a secret into.mcp.json.
Verify before handing over: the target tree matches the layout above, and
python3 ${CLAUDE_SKILL_DIR}/../../../scripts/validate_template.py
passes against the source template.
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.

scaffold-project is a skill published in the GitHub repository plugin87/ux-ui-agent-skills (2,012 stars, last pushed 6d ago), licensed MIT. It adds 39 tokens to every session and 1,098 once invoked, about $0.0002 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 2026-10-07.
