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 | $0.00331 | $0.00331 |
| Opus 5 | $0.00166 | $0.00166 |
| Sonnet 5 | $0.00066 | $0.00066 |
| Haiku 4.5 | $0.00033 | $0.00033 |
Grade A, and why
copilot-kit frontend.instructions.md 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 yesterday.
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
Frontend/UI Standards
🎨 Before Any UI Work
READ: .github/skills/frontend-design/SKILL.md
⚠️ ANTI-PATTERNS (NEVER DO)
| ❌ Don't | ✅ Do |
|---|---|
| Bento grids everywhere | Ask if grid is needed |
| Mesh/Aurora gradients | Consider solid colors first |
| Dark + neon as default | Ask for color preference |
| Same layout every time | Vary based on content |
| Skip asking preferences | Always ask when unclear |
📐 Core Principles
- Mobile-first: Start with mobile, scale up
- 8-point grid: Use multiples of 8 for spacing
- 60-30-10 color rule: Primary 60%, Secondary 30%, Accent 10%
- Accessibility: WCAG 2.1 AA minimum
🎯 Touch Targets
- Minimum 44px × 44px for mobile
- 8px+ spacing between targets
- Primary CTAs in thumb zone
⚡ Performance
- Lazy load images below fold
- Use
loading="lazy"on images - Prefer CSS animations over JS
- Animate only
transformandopacity
🔧 Tailwind (if used)
- Use design system scale, not arbitrary values
- Extract repeated patterns to components
- Follow v4 CSS-first configuration
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.
