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 | $0.00072 | $0.01440 |
| Opus 5 | $0.00036 | $0.00720 |
| Sonnet 5 | $0.00014 | $0.00288 |
| Haiku 4.5 | $0.00007 | $0.00144 |
Grade A, and why
shadcn-tailwind 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 12d 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.

shadcn Tailwind Implementation Patterns
Use this skill when the UI stack is React or Next.js with shadcn/ui and Tailwind CSS. Reuse the general react or react-nextjs skill for application logic and use this skill for component styling, primitives, variants, and utility hygiene.
When to Use
- Building or modifying UI with shadcn/ui components and Radix primitives
- Styling components with Tailwind CSS utility classes in a React or Next.js project
- Creating component variants, extending shadcn primitives, or composing design system elements
- Reviewing Tailwind class hygiene, responsive behavior, or design token consistency
When NOT to Use
- Task is about React logic, hooks, or state without styling specifics — use
react - Task is about Vue/Nuxt with Vuetify or PrimeVue — use
vuetify-primevue - Task is about visual design decisions (color palette, typography scale, animation craft) — use

Delivery Workflow
Use the checklist below and track progress:
shadcn Tailwind progress:
- [ ] Step 1: Discover existing UI primitives, tokens, and utility conventions
- [ ] Step 2: Reuse or extend existing shadcn/ui components
- [ ] Step 3: Implement variants and layout with disciplined Tailwind usage
- [ ] Step 4: Verify accessibility and responsive behavior
- [ ] Step 5: Review class hygiene, consistency, and reuse
Component Reuse Rules
- Reuse existing shadcn/ui primitives before creating new wrappers.
- Keep wrappers thin and capability-focused; do not create parallel component libraries casually.
- Extend components through variants and composition rather than copy-pasting markup.
- Preserve the expected API shape of shared primitives unless a project-wide migration is intended.
Tailwind Utility Discipline
- Prefer readable class grouping over long unstructured class strings.
- Keep layout, spacing, typography, and state styles intentional.
- Reuse the project's utility helpers such as
cnor equivalent merge helpers when available. - Avoid one-off arbitrary values unless the design system genuinely needs them.
- Map recurring visual patterns into shared components or variants instead of repeating the same utility bundles.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

shadcn-tailwind is a skill published in the GitHub repository JakubMikolajek/codex-skills-collection (5 stars, last pushed 6d ago), licensed MIT. It adds 72 tokens to every session and 1,440 once invoked, about $0.0004 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.
