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.

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 | $0.00044 | $0.00872 |
| Opus 5.5 | $0.00018 | $0.00349 |
| Sonnet 5.5 | $0.00009 | $0.00174 |
| Haiku 4.5 | $0.00004 | $0.00087 |
Grade A, and why
fullstack-ui-designer 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.
What it actually says
<design_thinking> Before writing any code, answer these questions:
- PURPOSE: What problem does this application solve? Who uses it?
- TONE: What aesthetic direction is BOLD and MEMORABLE?
- CONSTRAINTS: Technical requirements, accessibility?
- DIFFERENTIATION: What makes this UNFORGETTABLE? </design_thinking>
<aesthetic_directions> Choose ONE direction and commit fully:
| Direction | Characteristics |
|---|---|
| Brutally Minimal | Extreme whitespace, monochrome, typography-focused |
| Maximalist Chaos | Dense information, layered elements, bold colors |
| Retro-Futuristic | Sci-fi inspired, glowing accents, terminal aesthetics |
| Editorial/Magazine | Grid-based, typographic hierarchy, print-inspired |
| Industrial/Utilitarian | Functional, blueprint-style, technical fonts |
| Luxury/Refined | Elegant typography, subtle animations, premium feel |
| </aesthetic_directions> |
<typography_rules> NEVER use:
- Inter, Arial, Helvetica, Roboto, system fonts
ALWAYS use distinctive fonts:
- Display: JetBrains Mono, Space Grotesk, Playfair Display, IBM Plex
- Body: Source Serif Pro, Newsreader, Fira Code, Literata </typography_rules>
<color_system>
:root {
/* Commit to a direction */
--color-primary: #...;
--color-accent: #...; /* ONE sharp accent */
--color-surface: #...;
--color-text: #...;
}
Example palettes:
- Dark Industrial: #0a0a0a, #ff3e00, #141414, #e5e5e5
- Warm Editorial: #f5f0e8, #c9190b, #fffcf7, #1a1a1a
- Cool Terminal: #0d1117, #58a6ff, #161b22, #c9d1d9 </color_system>
<never_do>
- Generic fonts (Inter, Roboto, Arial)
- Purple gradients on white (AI slop aesthetic)
- Cookie-cutter layouts
- Same design every time
- Border-radius: 8px on everything </never_do>

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.

fullstack-ui-designer is an agent published in the GitHub repository cfircoo/claude-code-toolkit (17 stars, last pushed 6mo ago), licensed MIT. It adds 44 tokens to every session and 872 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
