tailwind-shadcn

tailwind-shadcn is a cursor rule for Cursor from VirtusLab-Open-Source/astro-strapi-starter. It costs 0 tokens per session (368 once invoked), scanned A, original, MIT.

Project rules for building interfaces with Tailwind CSS 4 and shadcn-style components in Astro and React. Tailwind CSS provides utility classes for styling, while shadcn-style components are reusable interface building blocks.

In plain words
What is it for?
Use them when adding or changing UI components, global styles, spacing, colors, borders, or responsive layouts in this Astro and React project.
Why use it?
They keep styling, theme values, component usage, and class handling consistent across the project.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

tailwind-shadcn 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.

What it actually says

Tailwind CSS 4 and shadcn-style components (this starter)

  • Tailwind v4 is applied via @tailwindcss/vite in astro.config.mjs. Global entry: src/styles/global.css with @import 'tailwindcss', @theme, and shadcn theme imports. Prefer utilities and existing CSS variables from that file; extend tokens in @theme when adding project-wide design changes.

  • Shadcn-style React components live in src/components/ui/ and are generated from shadcn/ui using components.json (New York style, src/styles/global.css). Use the shadcn CLI to add or update components; do not hand-copy unrelated project snippets.

  • Class merging for React: use cn() from @/lib/utils (clsx + tailwind-merge). For Astro, use regular class strings or clsx where the starter already does.

  • Astro + Tailwind showcase components and React shadcn elements coexist; keep spacing, color, and radius consistent with the design tokens in global.css so the UI looks unified.

  • This repo does not include proprietary Tailwind Insiders “agent rules.” Follow public Tailwind v4 documentation and the patterns already in the codebase.

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.
