 "title": "Block arbitrary Tailwind values in agent-written UI",
 "page_title": "How to block arbitrary Tailwind values in agent-written UI with Lint",
 "summary": "Flag off-scale Tailwind values so agents use your theme's spacing, colors, and sizes instead.",
 "who": "A front-end developer whose coding agent keeps adding one-off pixel values like p-[13px] that break the design system.",
 "problem": "Agents often invent arbitrary Tailwind values. These pass review in isolation but drift the UI away from the theme.",
 "outcome": "Arbitrary values are reported as Lint errors, and the error points the agent back to values already in the theme.",
 "steps": [
  "Run `npm install -D @shadcn/lint eslint @typescript-eslint/parser` in the project.",
  "Create eslint.config.mjs with the shadcn plugin and the rule \"shadcn/no-arbitrary-values\": \"error\", as shown in the React ESLint setup.",
  "Run `npx eslint .` and confirm it reports any existing arbitrary values.",
  "Fix the reported files or add the Lint command to package.json as the Lint script."
 ],
 "agent_prompt": "Use the GitHub repo shadcn-ui/lint to set up the no-arbitrary-values rule in <project-path>. Follow the README ESLint setup for React, then run the lint command. Expected output: a list of arbitrary Tailwind values in the project, or zero errors. Verify that the rule reports a test class such as p-[13px] in one component file.",
 "agents": [
  "any"

 "difficulty": "Intermediate",
 "time": "30 minutes",
 "basis": "readme",
 "caveat": "The README says Oxlint reads only the script blocks of Vue and Svelte files, not their templates, so template classes need ESLint.",

 "lang": "typescript",
 "requirements": [
  "Node.js 20.19 or later",
  "A Tailwind v4 project (shadcn/ui is not required)",
  "ESLint 9.30 or later, or Oxlint 1.80 or later",
  "A React, Vue, or Svelte project"
