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.

Fable 5.1 $0.00071 $0.03388
Opus 5.5 $0.00028 $0.01355

Security

Grade A, and why

premium-saas-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 22d 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.

Origin

This is a copy

How it starts

The opening of the file, as written. The whole thing — 571 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Premium SaaS Design Framework

In Stanford's large 2002 web credibility study (B.J. Fogg and colleagues), a site's visual design was the factor people mentioned most often when they judged whether to trust it.

This skill captures the professional design workflow used by senior product teams and UI/UX designers, adapted for AI-assisted development. The framework transforms AI from a "guessing machine" into a true design partner.


The Core Loop

DEFINE → BUILD → REVIEW → REFINE
   ↑                        │
   └────────────────────────┘

This loop is everything. It's used by real product teams and works wonders with AI.


The 7 Context Artifacts

AI needs context to produce premium results. These 7 documents form your "design contract" with AI:

1. Project Brief

What: Single document explaining what you're building, why, and for whom. Purpose: Gives AI direction and understanding of the project.

# Project Brief: [Product Name]

## What We're Building
[Description of the product/website]

## Primary Target Audience
- [Persona 1]: [Description]
- [Persona 2]: [Description]

## Goals
1. [Primary goal - e.g., drive signups]
2. [Secondary goal - e.g., build trust]
3. [Tertiary goal - e.g., explain the product]

## Requirements
- Fully responsive (mobile-first)
- Blazing fast performance
- Accessible (WCAG 2.1 AA)
- [Other requirements]

## Sections
1. Hero
2. Trust Logos
3. Features
4. [etc.]

Key Insight: Think of AI as a new team member. You wouldn't tell them "build me a website" without context.


2. Content Files (One Per Section)

What: Separate file for each section containing all copy/content. Purpose: Focuses AI on content separately from design.

# Hero Section Content

## Headline
[Main headline text]

## Subheadline
[Supporting text]

## CTA Primary
Text: [Button text]
Action: [What happens on click]

## CTA Secondary
Text: [Link text]
Action: [What happens on click]

## Social Proof (optional)
[Trust indicators, stats, etc.]

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.
