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 | $0.00022 | $0.00653 |
| Opus 5 | $0.00011 | $0.00327 |
| Sonnet 5 | $0.00004 | $0.00131 |
| Haiku 4.5 | $0.00002 | $0.00065 |
Grade A, and why
magic-ui-generator 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 5d 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.

Magic UI Generator
Leverage Magic by 21st.dev to build modern, responsive UI components using an AI-native workflow that prioritizes choice and design excellence.
Context
This skill leverages Magic by 21st.dev to build modern, responsive UI components. Instead of generating a single standard solution, it focuses on providing multiple design variations to choose from, drawing inspiration from a curated library of real-world components and premium design patterns (Shadcn UI, Magic UI, Aceternity, etc.).
When to Use
Trigger this skill whenever:
- A new UI component is requested (e.g., pricing tables, contact forms, hero sections).
- Enhancing an existing UI element with animations, better styling, or advanced features.
- Brainstorming different design directions for a specific feature.
- Professional logos or icons are needed (via the built-in SVGL integration).
Execution Workflow
- Analyze Requirements: Review the component description. Ensure the target output aligns with the project's stack (e.g., Next.js, TypeScript, Tailwind CSS). Define clear constraints for accessibility and responsiveness.
- Generate Variations: Interface with the Magic MCP server or use the
browser_subagentto explore 21st.dev/magic to generate several distinct, unconventional styles for the requested component.- Pro Tip: Use descriptive prompts pushing for modern aesthetics: "avant-garde SaaS pricing table with glassmorphism and animated borders" or "highly immersive contact form with dynamic floating labels."
- Present Options: Briefly describe the generated variations side-by-side. Highlight stylistic differences, layout approaches, and premium features (sticky headers, hover animations, etc.).
- Integrate Selection: Once a favorite variation is chosen:
- Integrate the fully functional, production-ready TypeScript code.
- Ensure dependencies (
lucide-react,framer-motion) are installed. - Handle proper props, types, and responsive behaviors.
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.

magic-ui-generator is a skill published in the GitHub repository beel-collab/presets.dev (3 stars, last pushed 4mo ago), licensed MIT. It adds 22 tokens to every session and 653 once invoked, about $0.0001 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 2026-09-03.
