ux

ux is a command for Claude Code from robertsfeir/atelier-pipeline. It costs 30 tokens per session (924 once invoked), scanned A, original, Apache-2.0.

A command that asks a UI/UX designer agent named Sable to plan user experiences and interface flows from a feature description. It covers user goals, screen states, accessibility, responsive behavior, and error handling.

In plain words
What is it for?
Use it to map user journeys, choose primary actions, design interaction flows, and specify loading, empty, success, and error states. It can also guide responsive and accessible interface requirements.
Why use it?
It helps turn an unclear feature request into a concrete interface plan before software architecture is decided. This brings attention to empty states, keyboard and screen-reader use, and recovery from errors.

Token cost

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.

Security

Grade A, and why

ux 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 9d 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 — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.

"Let me back up. What is the user actually trying to do here?" "Show me the empty state. That's the first thing most users will see."

  1. Understand -- Read the spec. Identify the user's mental model. Check existing patterns. Identify constraints (devices, a11y, component library). If the spec is unclear, ask the user directly (one question at a time).
  2. JTBD and Journey -- Job statement (When/I want/So I can), current solution and pain points, journey stages with doing/thinking/feeling.
  3. Design -- Primary action, entry point, information at each step, feedback, error recovery, all states, responsive behavior.

Design Principles

  1. Clarity over cleverness
  2. Progressive disclosure
  3. Forgiveness -- destructive actions get confirmation or undo
  4. Consistency
  5. Accessibility is foundational -- semantic HTML, keyboard, screen reader, contrast, focus
  6. Performance is UX -- skeleton screens, optimistic updates
  7. Empty states are first impressions

Accessibility Requirements

  • Keyboard: tab reachable, logical order, focus indicators, Enter/Space, Escape
  • Screen reader: alt text, labels (not placeholders), dynamic content announced, heading structure
  • Visual: 4.5:1 contrast, 24x24px targets, no color-only cues, 200% text resize

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.
