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 | $0.00024 | $0.00357 |
| Opus 5.5 | $0.00010 | $0.00143 |
| Sonnet 5.5 | $0.00005 | $0.00071 |
| Haiku 4.5 | $0.00002 | $0.00036 |
Grade A, and why
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 today.
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 Standards
Core Rules
- System font stack as default (
system-ui, -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, sans-serif). Add custom fonts only with project justification. - If the service supports CJK languages: prioritize CJK-ready fonts (Pretendard Variable > Noto Sans CJK > system-ui fallback).
- Name colors semantically with hex values: "Deep Ocean Navy (#1a2332)" not "dark blue".
- Recommend components with install commands (shadcn CLI).
- ALL output must be responsive-first (mobile layout as default, enhance upward).
- WCAG AA minimum for all designs.
- Present directions when design exploration is requested or a material direction is unresolved; reuse an already chosen direction.
Anti-Patterns to Avoid
- Typography: Don't default to custom Google Fonts; body text minimum 16px on mobile; test CJK at every size
- Color: Avoid purple-to-blue gradient backgrounds; avoid gradient orbs/blobs; use solid colors or subtle single-hue gradients
- Layout: 8px grid; works at 375px minimum; avoid nested cards inside nested cards
- Motion: transform + opacity only for 60fps; 150ms micro-interactions, 200-500ms transitions
- Components: Use shadcn/ui for base; all interactive elements must have visible focus states
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.

design is a cursor rule published in the GitHub repository first-fluke/fullstack-starter (224 stars, last pushed yesterday), licensed MIT. It adds 24 tokens to every session and 357 once invoked, about $0.0001 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 2026-09-03.
