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 | $0.00538 | $0.00538 |
| Opus 5 | $0.00269 | $0.00269 |
| Sonnet 5 | $0.00108 | $0.00108 |
| Haiku 4.5 | $0.00054 | $0.00054 |
Grade A, and why
ultimate.UIUX.design.skills CLAUDE.md 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
CLAUDE.md
This repository is Design Pro — a knowledge base that gives you senior-level design judgment across two tracks: 🖥️ interfaces (screens, apps, components, design systems) and 🎨 visual & marketing design (decks/PPT, social carousels & posts, ads, A4/A3 posters, flyers, business cards, event banners, email/newsletters, infographics, brand kits).
For any design work (designing, building, styling, or reviewing anything visual), follow the operating instructions in AGENTS.md and use the knowledge base under knowledge/ via progressive disclosure.
Quick start:
- Read
knowledge/INDEX.mdandknowledge/01-principles/decision-framework.md. - For a fixed-canvas asset (deck/social/print/email), also lock the canvas via
knowledge/08-visual-composition/format-specs.mdbefore designing. - Load only the references the task needs (use the index routing table).
- Self-review against
knowledge/05-quality/review-checklist.mdbefore declaring done.
If this repo is installed as a Claude Code plugin, the ui-ux-pro skill activates automatically on design requests. Commands — interfaces: /ui-build, /ui-review, /design-system; visual/marketing: /make-deck, /make-carousel, /make-creative. Subagents: ui-designer, frontend-implementer, visual-designer, design-reviewer.
Non-negotiables: one focal point / primary action per artifact · 8pt spacing · legible type (16px web body / ~24pt slide / large-for-distance on posters / 14–16px email) · contrast 4.5:1 (incl. text over images) · interfaces handle all 5 states (empty/loading/error/success/ideal) · fixed-canvas assets set correct size/bleed/color space first · semantic HTML + visible focus + keyboard + alt text · motion only on transform/opacity with reduced-motion fallback · one brand family across a set · restraint over decoration.
Scope note: this repo owns the visual design craft. For marketing copy, strategy, and distribution (ad copy, SEO, CRO, deliverability), pair it with a marketing-skills library.
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.
