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

shadcn-ui 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 10d 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

shadcn/ui Agent Workflow

When asked to work with shadcn/ui components, follow this imperative workflow to ensure you generate correct code that aligns with the project's configuration.

1. Context Gathering

Before generating any code or installing components, you must determine the project's configuration:

  • Inspect components.json to find the aliases, tailwind configuration, and the style (e.g., default or new-york).
  • Identify the base library being used (e.g., lucide-react or Radix primitives).
  • Check which components are already installed in the components/ui/ directory.

2. Component Installation & Discovery

  • Search first: If a required component is not installed, search the documentation or registry for it.
  • Install securely: To install a component, use the official CLI command npx shadcn@latest add [component].
  • Registry Security: Do NOT blindly install components from third-party or untrusted registries (e.g., via URLs) without explicitly reviewing the source code first and requesting user approval.

3. Composition & Customization

When assembling components (e.g., forms, dashboards, settings pages):

  • Follow patterns: Use established shadcn/ui composition rules. For example, use Form and FormField wrappers for forms, and ToggleGroup for option sets.
  • Semantic CSS: Use the project's semantic CSS variables (e.g., bg-background text-foreground, bg-primary) rather than hardcoded Tailwind colors.
  • Customization: To customize a component, edit its source code in the components/ui/ directory directly. Do not wrap it in unnecessary outer divs just to apply styles if modifying the component itself is cleaner.

4. Version Upgrades

When upgrading shadcn/ui components or the CLI itself, always review the official changelog before running update commands to ensure no breaking changes affect customized components.

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.
