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 | $0.00028 | $0.00363 |
| Opus 5 | $0.00014 | $0.00181 |
| Sonnet 5 | $0.00006 | $0.00073 |
| Haiku 4.5 | $0.00003 | $0.00036 |
Grade A, and why
ui-build 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.
What it actually says
Design and build: $ARGUMENTS
Work through the full UI/UX Design Pro loop:
- Orient — read
knowledge/INDEX.mdandknowledge/01-principles/decision-framework.md. - Understand — identify the job-to-be-done and the single primary action. If the brief is underspecified, apply the framework's opinionated defaults and state your assumptions; ask only if a decision genuinely blocks you.
- Load the relevant references via the index routing table (the matching
06-patterns/*playbook,02-foundations/*,03-components/*, and07-implementation/recipes.md). - Design then build — hierarchy → layout → tokens → components → all five states (empty/loading/error/success/ideal) → motion → responsive → accessibility. Match the existing repo's stack if there is one; otherwise default to React + TypeScript + Tailwind v4 + shadcn/ui + Radix + Motion + Lucide. Own styling, borrow behavior from accessible primitives.
- Self-review — run the result against
knowledge/05-quality/review-checklist.md, fix what fails, and report how it holds up (contrast, focus, states, responsive, reduced-motion).
Deliver complete, copy-pasteable code (with imports and any deps to install), plus a short note on assumptions and what the user should verify on real devices.
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.

ui-build is a command published in the GitHub repository ca-who-codes/ultimate.UIUX.design.skills (4 stars, last pushed 1mo ago), licensed MIT. It adds 28 tokens to every session and 363 once invoked, about $0.0001 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.
Other commands, from other repositories
accessibility-specialist
Use when a screen might fail WCAG. Unlabeled inputs, no keyboard path, contrast below AA, missing landmarks, broken heading order, screen reader gaps, or a request for an a11y review or EU Accessibility Act check.
color-specialist
Use when colour is failing. Contrast below AA, a palette with no system behind it, dark mode that is only inverted light mode, or semantic colours that carry no meaning.
conversational-ui-designer
Use when designing a chat or assistant interface. Message layout, bot personality, streaming and typing states, rich message cards, error recovery, or voice input.
form-designer
Use when a form is losing people. Too many fields, validation that interrupts typing, unclear required fields, a multi-step flow with no sense of progress, or inputs with no labels.
motion-designer
Use when animation feels wrong. Transitions too slow or too bouncy, motion with no purpose, blanket transitions on every property, no reduced-motion support, or animation that drops frames.
spacing-layout-specialist
Use when spacing looks arbitrary. Padding and margins off any scale, inconsistent gaps between the same components, no grid underneath, or a layout that needs a denser mode.
