storybook

storybook is a skill for Claude Code, Codex from pproenca/dot-skills. It costs 242 tokens per session (3,716 once invoked), scanned A, original, MIT.

A guide to setting up Storybook, a tool for viewing and testing UI components in isolation, in TypeScript and React projects.

In plain words
What is it for?
It helps create component stories, configure controls and shared providers, mock network requests, and write interaction tests.
Why use it?
It helps avoid broken configuration and inconsistent stories that prevent controls, documentation, accessibility checks, and interaction tests from working.

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

storybook 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 6d 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.

dot-skills Storybook Best Practices

Comprehensive guide for using Storybook 9+ as the workshop and test bench for a TypeScript/React component library. 52 rules across 8 categories, ordered by the lifecycle of a component in your design system: a wrong .storybook/main.ts cascades into every story; a malformed CSF Meta blocks autodocs, controls, tests, and the a11y panel for that file.

What this skill covers

  1. Setup — main.ts, preview.ts, framework selection (Vite vs Webpack, Next.js vs React-only), addon installation via the CLI, staticDirs.
  2. Story authoring (CSF3) — satisfies Meta<typeof Component>, named exports = stories, tags: ['autodocs'] placement, when render is appropriate, story naming conventions.
  3. Args, argTypes, controls — when to rely on inference, when to declare control: 'select', fn() from storybook/test for callbacks, args vs parameters vs globals.
  4. Decorators & composition — global providers in preview.ts, MSW for network mocks, subpath-import module mocking (Storybook 9+), decorator signature pitfalls.
  5. Interaction testing — play functions, the storybook/test import path (NOT @storybook/test), destructured canvas/userEvent, findBy* over waitFor, addon-vitest for CI, portable stories.
  6. Accessibility (axe-core via @storybook/addon-a11y) — parameters.a11y.test = 'error' as a real gate, per-rule disables, runOnly scoped to your WCAG target, portal context, globals.a11y.manual for intentional-violation fixtures.
  7. Documentation & design system — autodocs vs MDX, MDX referencing stories with <Canvas of={...} />, status tags, design tokens as stories, Figma links via parameters.design.
  8. Build & deployment — Vite over Webpack, on-demand bundling for large libraries, deploy to Chromatic/Vercel for designer review, CI cache configuration.

When to Apply

Reach for this skill when:

  • Editing or creating a *.stories.tsx, *.mdx, .storybook/main.ts, .storybook/preview.ts, or vitest.config.ts that loads storybookTest.
  • Setting up Storybook on a new project (framework choice, npx storybook init follow-up).
  • Adding or upgrading an addon (a11y, vitest, designs, msw).
  • Wiring component tests through play functions and the Vitest addon.
  • Investigating "Storybook is slow", "controls show text instead of select", "a11y panel shows nothing for my dialog", "play function is flaky in CI".

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.
