A set of rules for designing polished web interfaces with tactile depth, animated transitions, and carefully choreographed interactions. It targets bespoke layouts rather than standard component-library appearances.

It is for luxury landing pages, portfolios, editorial interfaces, and high-end SaaS screens that need detailed layout, typography, and interaction work.

It provides a defined visual and motion direction when a basic or clinical interface is not suitable.

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.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00020	$0.01660
Opus 5	$0.00010	$0.00830
Sonnet 5	$0.00004	$0.00332
Haiku 4.5	$0.00002	$0.00166

Security

Grade A, and why

soft-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 4d 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.

Skill: soft-design

Agent Skill: Principal UI/UX Architect & Motion Choreographer (Awwwards-Tier)

Overview

Engineers high-end, agency-level digital experiences characterized by tactile haptic depth, cinematic spatial rhythm, obsessive micro-interactions, and fluid spring physics. Rejects generic commodity SaaS templates in favor of bespoke layout archetypes, nested double-bezel enclosures, and purposeful motion dynamics.

When to Use

When tasked with creating luxury, premium, Awwwards-tier landing pages, portfolio showpieces, or editorial SaaS interfaces.
When explicitly prompted for "soft UI", "expensive design", "Apple-level polish", or "calm aesthetics".
When standard component libraries feel too clinical or generic.

Rules & Patterns

1. Absolute Zero Directive (Strict Anti-Patterns)

Banned Fonts: Inter, Roboto, Arial, Open Sans, Helvetica. (Use Geist, Clash Display, PP Editorial New, or Plus Jakarta Sans).
Banned Icons: Thick-stroked Lucide, FontAwesome, or Material Icons. Use ultra-light, precise line icons (Phosphor Light, Remix Line).
Banned Borders & Shadows: Generic 1px solid gray borders. Harsh dark drop shadows (rgba(0,0,0,0.3)).
Banned Layouts: Edge-to-edge sticky navbars glued to the top. Symmetrical 3-column Bootstrap-style grids without massive whitespace.
Banned Motion: Standard linear or ease-in-out transitions. Instant state changes without interpolation.

2. The Creative Variance Engine

Before writing code, consciously pick ONE combination:

Vibe & Texture Archetypes

Ethereal Glass (SaaS / AI / Tech): Deep OLED black (#050505), subtle radial mesh gradients, vantablack cards with backdrop-blur-2xl and white/10 hairlines.
Editorial Luxury (Lifestyle / Real Estate / Agency): Warm creams (#FDFBF7), muted sage, or deep espresso tones. Variable serif headings with subtle CSS noise overlay (opacity-[0.03]).
Soft Structuralism (Consumer / Health / Portfolio): Silver-grey or pure white backgrounds, bold grotesk typography, airy floating components with ultra-diffuse ambient shadows.

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.
