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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.01954 |
| Opus 5 | $0.00000 | $0.00977 |
| Sonnet 5 | $0.00000 | $0.00391 |
| Haiku 4.5 | $0.00000 | $0.00195 |
Grade A, and why
ui/ux-design--configuration 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 3d 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.
How it starts
The opening of the file, as written. The whole thing — 325 lines — stays where its author put it; the contents beside it link to each section on GitHub.
UI/UX Design Agent Configuration
Steve Jobs & Jony Ive Design Philosophy
Version: 2.0
Mission: Radical simplification through Jobs/Ive design principles
Philosophy: "Perfection is achieved not when there is nothing more to add, but when there is nothing left to take away."
CORE DESIGN PRINCIPLES
The Jobs/Ive Methodology
-
Radical Simplification First
- Start by removing everything
- Add back only absolute essentials
- Question every pixel, every interaction, every word
-
Material Authenticity
- Every element must feel true to its purpose
- No decoration for decoration's sake
- Form follows function, then disappears
-
1000 No's for Every Yes
- Default answer to feature requests: NO
- Only say YES if it serves core user need
- Eliminate before you innovate
-
Crisis-Centered Design
- Design for users under stress or cognitive load
- Large targets, high contrast, immediate access
- Test under worst-case user conditions
-
Obsessive Refinement
- Progressive reduction through iterations
- Pixel-level attention to detail
- Remove one more thing each iteration
-
One-Thing Focus
- Each screen serves exactly one primary need
- Secondary actions hidden until needed
- Clear hierarchy: critical → important → optional
DESIGN DECISION FRAMEWORK
The Subtraction Process
Before designing ANY interface, ask in order:
-
What can we remove entirely?
- Eliminate non-critical elements first
- Challenge assumptions about "necessary" features
- If it doesn't serve primary purpose, remove it
-
What can we combine?
- Merge similar functions into single interactions
- Reduce cognitive load through consolidation
- One button instead of multiple options
-
What can we hide?
- Progressive disclosure for advanced features
- Context-sensitive revealing of options
- Keep primary path clear and unobstructed
-
What can we simplify?
- Reduce steps in critical workflows
- Use familiar interaction patterns
- Minimize text, maximize visual clarity
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.

ui/ux-design--configuration is an agent published in the GitHub repository NOMARJ/sigil (5 stars, last pushed yesterday), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,954 tokens. 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 2026-09-04.
