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 | $0.00054 | $0.00995 |
| Opus 5 | $0.00027 | $0.00498 |
| Sonnet 5 | $0.00011 | $0.00199 |
| Haiku 4.5 | $0.00005 | $0.00100 |
Grade A, and why
UI Library Selection 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 11d 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.

Guide for Selecting a UI Component Library
Choosing the right UI library is a crucial architectural decision that impacts development speed, application performance, and long-term maintainability. This guide covers how to evaluate and select the best UI library or styling solution for your project.
1. Evaluation Criteria
When comparing libraries, consider the following technical and operational factors:
| Criterion | What to Evaluate | Why it Matters |
|---|---|---|
| Bundle Size & Tree-shaking | Does it support ES modules? Can you import individual components? | Impacts initial load time and overall app performance. |
| Accessibility (a11y) | Does it follow WAI-ARIA guidelines? Are components keyboard navigable? | Ensures legal compliance and usability for all users. |
| Theming & Customization | How easy is it to override default styles? Does it support dark mode? | Determines if you can match your brand identity without fighting the framework. |
| TypeScript Support | Are types included or maintained via DefinitelyTyped? Are they strict? | Enhances developer experience, auto-completion, and bug prevention. |
| Community & Maintenance | Look at GitHub stars, open issues, release frequency, and ecosystem. | Indicates longevity and likelihood of finding solutions to obscure bugs. |
2. React UI Libraries Comparison
| Library | Paradigm | Pros | Cons | Best For |
|---|---|---|---|---|
| shadcn/ui | Copy-paste components (not a dependency) | Full control, Tailwind native, high quality | Requires manual updates, boilerplate in your repo | Modern SaaS, custom designs, team with strong React/Tailwind skills |
| MUI (Material-UI) | Full UI Framework | Massive ecosystem, highly featured, robust | Large bundle size, Material design look is hard to shake | Enterprise apps, internal tools, rapid prototyping |
| Radix UI | Unstyled primitives | Perfect accessibility, bring your own styles | Steep learning curve for styling from scratch | Design systems, highly custom UIs |
| Chakra UI | Styled components with utility props | Excellent developer experience, accessible | Runtime CSS-in-JS overhead | Startups, fast-moving teams wanting good defaults |
| Mantine | Full UI Framework | Huge amount of hooks/components, fully featured | Custom styling approach, learning curve | Feature-rich web apps, dashboards |
| Ant Design | Full UI Framework | Comprehensive, great for data-heavy apps | Large bundle, opinionated design, localization hurdles | Complex enterprise admin panels |
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.

UI Library Selection is a skill published in the GitHub repository GktuOktay/ai-skills (2 stars, last pushed 8d ago), licensed MIT. It adds 54 tokens to every session and 995 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 2026-08-31.

prototype
Build a throwaway prototype to answer a design question. Use when the user wants to sanity-check whether a state model or logic feels right, or explore what a UI should look like.
design-taste-frontend
Anti-slop frontend skill for landing pages, portfolios, and redesigns. The agent reads the brief, infers the right design direction, and ships interfaces that do not look templated. Real design systems when applicable, audit-first on redesigns, strict pre-flight check.
design-everyday-things
Apply foundational design principles: affordances, signifiers, constraints, feedback, and conceptual models. Use when the user mentions "why is this confusing", "affordance", "error prevention", "discoverability", "human-centered design", "mental model", "mapping", "seven stages of action", "users keep making…
