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 | $0.00055 | $0.03982 |
| Opus 5 | $0.00028 | $0.01991 |
| Sonnet 5 | $0.00011 | $0.00796 |
| Haiku 4.5 | $0.00006 | $0.00398 |
Grade A, and why
frontend-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 8d 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 — 486 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Frontend Design
Create distinctive, production-grade web interfaces that avoid generic AI aesthetics.
Design Thinking Process
1. Understand Context
Before writing code, answer:
- Purpose: What problem does this interface solve? Who uses it?
- Audience: Technical sophistication, expectations, emotional state when arriving
- Constraints: Framework requirements, browser support, performance budget, accessibility needs
2. Commit to an Aesthetic Direction
Choose a specific point of view — not "clean and modern" but a real aesthetic:
| Direction | Characteristics |
|---|---|
| Brutally minimal | Monochrome, system fonts, stark spacing, no decoration |
| Maximalist | Dense, layered, multiple type scales, rich texture |
| Retro-futuristic | Neon accents, dark backgrounds, grid lines, monospace |
| Organic/natural | Soft shapes, earth tones, hand-drawn elements, warm |
| Luxury/refined | Thin serifs, generous whitespace, muted palette, restrained |
| Playful/toy-like | Rounded shapes, bright primaries, bouncy animations |
| Editorial/magazine | Strong grid, dramatic type hierarchy, pull quotes |
| Brutalist/raw | Exposed structure, monospace, raw HTML feeling |
| Art deco/geometric | Symmetry, metallic accents, decorative borders, angular |
| Soft/pastel | Light palette, gentle gradients, rounded, approachable |
| Industrial/utilitarian | Exposed grid, status indicators, dense information |
3. Identify the Memorable Thing
Every interface should have one element someone remembers:
- An unexpected interaction
- A distinctive type treatment
- A bold color choice
- An animation that surprises
- A layout that breaks convention
4. Execute with Intentionality
The key is commitment, not intensity. Maximalism executed fully works. Minimalism executed with precision works. The mushy middle does not.
Typography
Principles
- Choose distinctive fonts, NOT defaults (avoid Arial, Inter, Roboto for display use)
- Pair a display font (personality) with a body font (readability)
- Size hierarchy: display (48-96px), heading (24-36px), body (16-18px), small (12-14px)
- Tight letter-spacing on large display text (-0.02 to -0.04em)
- Normal or slightly loose spacing on body text
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.

frontend-design is a cursor rule published in the GitHub repository thatrebeccarae/claude-marketing (132 stars, last pushed 3mo ago), licensed MIT. It adds 55 tokens to every session and 3,982 once invoked, about $0.0003 per session on Opus 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.
