The invisible parts are: the disabled state with the right cursor and the right focus behavior, the loading state with the spinner that does not change the button's width, the focus ring that is visible against every background the button might land on, the keyboard activation on Enter and Space, the ARIA labeling for screen readers when the button is icon-only, the hover and active states that respect the user's reduced-motion preference, the typed props that catch misuse at the editor rather than at runtime, and the prop documentation that lets the next person to import it know how to use it correctly. Every component carries that surface area, and every component generated quickly tends to skip most of it."

      "type": "paragraph",
      "text": "The result is the codebase full of components that look right in Storybook and are subtly broken in production. The button that loses its focus ring on dark backgrounds. The dropdown that traps keyboard focus when it opens but does not return focus to the trigger when it closes. The dialog that scrolls the page underneath when the user scrolls inside it. The combobox that announces the wrong item to screen readers. None of these are deal-breakers individually. Cumulatively they make the application unusable for keyboard-only users and frustrating for everyone else, and the cost of fixing them later is much higher than the cost of getting them right the first time. The `/prism-component` skill is built for the right-the-first-time version: every component ships with the full state matrix, the ARIA coverage, the keyboard interactions, and the typed props, because each of those is part of what \"a component\" actually means."

The function looks right. It is missing the disabled state because the prompt did not mention it. It is missing the loading state because the prompt did not mention it. The ARIA attributes are absent or generic because the model defaults to whatever was most common in its training data, which is rarely the correct attribute set for the specific component. The keyboard interactions are whatever the underlying element provides by default, which is fine for a `<button>` and broken for a custom component built on a `<div>`. The component appears in the codebase, gets imported in five places, and the gaps are discovered one at a time over the next several months."

      "text": "Cursor and Copilot have a different version of the same problem. They suggest completions for the line you are typing, which is excellent for filling in the JSX of a component you have already structured and unhelpful for designing the component's contract. The contract (which props exist, which states are visible, which keyboard interactions are supported) has to be designed up front, and autocomplete cannot design it. The result is a component whose contract drifts as it gets extended: a new prop added without a default, a new state branch added without a corresponding type variant, an ARIA attribute added inconsistently across instances. Each addition feels small; the cumulative effect is a primitive that everyone in the team treats with caution because nobody fully trusts its behavior."

      "text": "A complete component has five parts. First, the typed contract: the props with their types, defaults, required vs optional, with TypeScript discriminated unions where the prop set varies by variant. Second, the state matrix: every visible state (default, hover, focus, active, disabled, loading, error, empty if applicable) implemented and demonstrated in Storybook. Third, the keyboard interactions: which keys do what, with the discipline that interactive elements respond to Enter and Space, that focusable elements have visible focus indicators, and that focus is managed correctly across complex interactions like menus and dialogs. Fourth, the ARIA coverage: roles, labels, descriptions, and live regions where applicable, calibrated to what the component actually does rather than what the model guesses. Fifth, the documentation: prop descriptions, usage examples, and accessibility notes, embedded in the source so the editor surfaces them on import."
    },
    {
      "type": "paragraph",
      "text": "These parts are not optional. A component that has the visual states without the keyboard interactions excludes keyboard users. A component that has ARIA without the right roles makes screen readers worse, not better. A component without typed props produces editor-time bugs that show up at runtime in the wrong contexts. The discipline of building the parts together is the discipline of treating components as primitives that the rest of the codebase will rely on, which is exactly what they are. The cost of skipping the discipline is paid by the next ten places that import the component."

The new component matches those conventions rather than introducing new ones. A button generated with `/prism-component` in a shadcn project looks and feels like the existing shadcn buttons; in a Material project, it follows the Material conventions."

Where the prop set varies by variant (an icon button has different required props from a text button), the contract uses TypeScript discriminated unions to enforce the variation at the type level. The contract is presented for review before code is generated, so the team can push back on prop names, default values, and required-vs-optional decisions while the cost of changing them is still cheap."

Each state has a Storybook entry so the team can review the visual treatment. The state implementation respects the user's preferences: `prefers-reduced-motion` disables motion, `prefers-color-scheme` adapts where the theme system supports it. Focus rings are visible against every background the component might land on; this is verified by axe-core and a manual contrast check during generation."
