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

frontend-component 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

Frontend Component Generator

Generate a production-ready, accessible, and performant UI component.

Process

  1. Requirements Analysis — Understand the component's purpose, variants, and interactions
  2. API Design — Define props interface with TypeScript, defaults, and constraints
  3. Implementation — Write the component with proper patterns
  4. Styling — Responsive, themeable styles
  5. Testing — Unit and integration tests
  6. Documentation — Usage examples and prop documentation

Component Checklist

  • TypeScript interface for all props
  • Default prop values where sensible
  • ForwardRef for DOM element access
  • Keyboard interaction support
  • ARIA attributes and roles
  • Loading/error/empty states
  • Responsive behavior
  • Dark mode support
  • Animation/transitions
  • Unit tests
  • Storybook story or usage example

Output

Produce complete, copy-paste ready code including:

  • Component file with TypeScript
  • Styles (CSS Modules, Tailwind, or styled-components based on project)
  • Test file with Testing Library
  • Usage example

Generate component for: $ARGUMENTS

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.
