Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 | $0.00030 | $0.04947 |
| Opus 5 | $0.00015 | $0.02474 |
| Sonnet 5 | $0.00006 | $0.00989 |
| Haiku 4.5 | $0.00003 | $0.00495 |
Grade A, and why
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 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 — 485 lines — stays where its author put it; the contents beside it link to each section on GitHub.
UX Designer
Design harness for Claude Code. Phases: Discovery → Brief & Milestones → Build & Converge.
The skill (parent agent) is a collector + variation manager. It runs discovery, writes the master brief and per-variation briefs, dispatches design-engineer sub-agents to build in isolated worktrees, then converges screenshots and merges the chosen variation.
The parent does NOT build code. Every variation — including variation_count == 1 — is dispatched to a design-engineer sub-agent. Build mechanics live in agents/design-engineer.md.
When to Use
- User asks to design a UI, landing page, dashboard, app screen, or visual interface
- User asks to prototype, wireframe, or mock up something
- User says "make this look good" or asks for design help on existing UI
- User provides a Figma reference, screenshot, or design system to replicate
- User wants to explore multiple visual variations
- User asks to build/update Storybook stories
- User wants animations, scroll effects, or immersive interactions
- User mentions "Claude Design" or wants that workflow
Core Philosophy
- Code is the deliverable — every artifact is shippable HTML/React/Vue/Svelte/Astro.
- Discovery before generation — fill gaps before building. Never guess direction.
- Visual verification — iterate on reality (screenshots), not assumptions.
- Parallel exploration — worktrees + sub-agents try multiple directions simultaneously.
AskUserQuestion
Every multiple-choice prompt uses the AskUserQuestion tool. Plain markdown is the fallback.
Load before first use (deferred tool):
ToolSearch({ query: "select:AskUserQuestion", max_results: 1 })
Constraints:
- 1-4 questions per call; 2-4 options per question
- Do NOT add an "Other" option — the tool adds it automatically
- Each option:
label(1-5 words) +description - Append
(Recommended)to label for top-pick when one direction is best multiSelect: trueonly for genuinely non-exclusive prompts
What ships with it
6 files 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.

ux-designer is a skill published in the GitHub repository clafollett/lafollettlabs-claude-plugins (2 stars, last pushed 1mo ago), licensed MIT. It adds 30 tokens to every session and 4,947 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 2026-08-31.
