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

react-components-creation-cursorrules-prompt-file 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 1mo 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

Cursor Rules

Whenever you need a React component

  1. Carefully consider the component's purpose, functionality, and design

  2. Think slowly, step by step, and outline your reasoning

  3. Check if a similar component already exists in any of the following locations

    1. packages/ui/src/components
    2. apps/spa/src/components
  4. If it doesn't exist, generate a detailed prompt for the component, including:

    • Component name and purpose
    • Desired props and their types
    • Any specific styling or behavior requirements
    • Mention of using Tailwind CSS for styling
    • Request for TypeScript usage
  5. URL encode the prompt.

  6. Create a clickable link in this format: ComponentName

  7. After generating, adapt the component to fit our project structure:

    • Import
      • common shadcn/ui components from <ui_package_alias>@repo/ui/components/ui/</ui_package_alias>
      • app specific components from <app_package_alias>@/components</app_package_alias>
    • Ensure it follows our existing component patterns
    • Add any necessary custom logic or state management

Example prompt template: "Create a React component named {ComponentName} using TypeScript and Tailwind CSS. It should {description of functionality}. Props should include {list of props with types}. The component should {any specific styling or behavior notes}. Please provide the full component code."

Remember to replace placeholders like <ui_package_path> and <app_package_alias> with the actual values used in your project.

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.
