format-storybook
Structure and organize Storybook files for scalability using battle-tested patterns. Based on "A Storybook format that scales with you" by Cassondra Roberts. Always use this skill when creating or editing any Storybook story file, writing template files, organizing a component library, setting up visual regression tests with Chromatic, or when the user asks anything about Storybook — even casual questions about file structure, controls, args, or how to document a component.
frontend-a11y
Write minimal, accessible HTML, CSS, and JavaScript without over-engineering. Always use this skill on every project, for every task that involves writing or reviewing HTML markup, building web components, creating forms, adding interactive elements like buttons, dialogs, accordions, or tabs, or auditing code for accessibility — even when the user doesn't explicitly mention accessibility, and even when working in a framework, CMS, or design system context. This skill is non-negotiable and applies regardless of project type, stack, or deadline. If you're about to reach for ARIA attributes, a dialog library, a focus-trap package, or a headless UI component, use this skill first.
frontend-conventions
Define and enforce consistent coding standards across HTML, CSS, and JavaScript. Always use this skill when naming a new class, variable, component, or file; setting up a new project's conventions; choosing a class prefix for a new CSS category; deciding on modifier API names (sizes, shades, hierarchy, breakpoints); or reviewing code for formatting and naming consistency. If you're about to invent a prefix, abbreviation, or modifier name without checking the conventions first, use this skill.
frontend-design-2010s
Create web interfaces with an authentic early-2010s aesthetic. Use this skill when the user wants a 2010s-era, Web 2.0, or retro corporate web look — gradient headers, glossy buttons, skeuomorphic icons, horizontal band layouts, and drop shadows from circa 2010–2014.
more-css
Write scalable, well-architected CSS using design tokens, cascade layers, and modern organization patterns. Use this skill as the default for any real project — if it has more than a handful of CSS files, multiple components, a team, a design system, or any kind of token or theming setup, this is the right skill.
tiny-css
Write minimal, efficient CSS for small or minimalist projects by trusting the browser instead of fighting it. Only use this skill for personal sites, prototypes, simple landing pages, or projects intentionally kept lean — if the project has multiple developers, a component library, a design token system, or more than a handful of CSS files, a more comprehensive CSS approach is needed. If you're about to write a CSS reset, declare a base font-size on :root, set default colors on body, use px for spacing, or reach for physical margin/padding properties, this skill will stop you.
