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 | $0.00000 | $0.00762 |
| Opus 5.5 | $0.00000 | $0.00305 |
| Sonnet 5.5 | $0.00000 | $0.00152 |
| Haiku 4.5 | $0.00000 | $0.00076 |
Grade A, and why
design 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 1mo 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.
This is a copy
97% identical to design — 5 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/design - UI/UX Design Principles Quick Reference
Purpose
Load the UI/UX Design Principles skill for framework-agnostic design patterns, layout principles, and enterprise UX guidelines.
CRITICAL: This skill should be invoked PROACTIVELY for ALL frontend work, regardless of framework (React, Flutter, etc.).
Quick Reference
| Command | Action |
|---|---|
/design |
Load comprehensive design principles |
/design layout |
Show layout and information architecture patterns |
/design hierarchy |
Show visual hierarchy principles |
/design components |
Show component design guidelines |
/design responsive |
Show responsive design patterns |
What You Get
- Top-Down Design Methodology (layout → features → components → details)
- Layout & Information Architecture (70/30 rule, grid systems)
- Visual Hierarchy Principles (F-pattern, Z-pattern, inverted pyramid)
- Enterprise UX Patterns (action hierarchy, search & filter, bulk actions)
- Component Design Guidelines (cards, buttons, empty states, loading states)
- Responsive Design Patterns (breakpoints, layout changes)
- Accessibility Standards (WCAG 2.1 AA compliance)
- Design System Principles (tokens, naming conventions)
- Common Pitfalls & Solutions
Quick Principles
Top-Down Design Order (ALWAYS Follow)
LEVEL 1: FRAME/LAYOUT (Highest Priority)
→ Space division, visual hierarchy, information architecture
LEVEL 2: FEATURE COMMUNICATION
→ Discoverability, action hierarchy, navigation
LEVEL 3: COMPONENT EFFECTIVENESS
→ Widget appropriateness, interaction patterns, feedback
LEVEL 4: VISUAL DETAILS (Lowest Priority)
→ Colors, shadows, animations, typography refinements
The 70/30 Rule
- 70% of space = primary content (what user came to see/do)
- 30% of space = secondary UI (navigation, filters, chrome)
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.

design is a command published in the GitHub repository terrene-foundation/metis (2 stars, last pushed 5mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 762 tokens. A static security scan graded it A with 0 findings. It is 97% identical to design, differing in 5 lines, and is treated as a copy.
