Automatically format JavaScript/TypeScript files after any Edit operation using prettier. This hook runs 'npx prettier --write' on any .js, .ts, .jsx, or .tsx file that Claude modifies, ensuring consistent code formatting. Uses npx so prettier doesn't need to be globally installed. Includes error suppression so it won't fail if prettier is not available.
Automatically format Python files after any Edit operation using black formatter. This hook runs 'black' on any .py file that Claude modifies, ensuring consistent Python code formatting. Requires black to be installed ('pip install black'). The command includes error suppression (2>/dev/null || true) so it won't fail if black is not installed.

Also use when the user mentions "engineering as marketing," "free tool," "marketing tool," "calculator," "generator," "interactive tool," "lead gen tool," "build a tool for leads," or "free resource." This skill bridges engineering and marketing — useful for founders and technical marketers.

Accessibility patterns for React and Next.js — semantic HTML, ARIA attributes, form labeling, keyboard navigation, focus management, and screen reader support. Use when building any interactive UI component or form.
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI).
