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 | $0.00124 | $0.01586 |
| Opus 5 | $0.00062 | $0.00793 |
| Sonnet 5 | $0.00025 | $0.00317 |
| Haiku 4.5 | $0.00012 | $0.00159 |
Grade A, and why
ux-design-from-scratch 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.

Design From Scratch (UX Creation Orchestrator) Skill
How this skill behaves (read first)
This is the front door for building a new design from zero, and the generative twin of
ux-design-review. Where design-review orchestrates the validation direction
(generative → audit), this skill orchestrates the compositional direction
(generative → generative): it sequences the scope ladder — foundations → components →
screens → flows — pulling in each lower-scope skill as the work needs it, then hands the result
to design-review for validation.
It is the executable form of the compositional orchestration section of
docs/orchestration-policy.md. Its whole job is to avoid two failures: building a single screen
with no system underneath it, and over-building everything (all foundations, all 12 components)
when the product only needs a few.
When NOT to use this skill: if the user asks for one specific artifact ("design a pricing page", "build a date-picker"), let that skill trigger directly. This orchestrator is for multi-artifact, from-scratch builds. Explicit scope overrides orchestration.
Step 0 — Establish the context profile (once)
The single most important field here is the inverse of the review case:
- Design system in play? For a true from-scratch build the answer is usually no → the foundation skills are in scope and come first. If the user does have tokens/a styleguide already, skip the foundations and start at components/screens, inheriting their system (the suppression matrix, applied to creation).
- What's being built — a single screen with its system, a small flow, or a whole product surface? This sets how far down the ladder to go and how many screens/components to compose.
- Platform — mobile vs. web (changes layout, touch targets, navigation patterns).
- Brand / audience / industry — drives the gated decisions inside the foundation and screen skills (color emotion, tone, security posture).
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-design-from-scratch is a skill published in the GitHub repository Uxcel-Lab/product-skills (12 stars, last pushed 2mo ago), licensed MIT. It adds 124 tokens to every session and 1,586 once invoked, about $0.0006 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.
