swatchdog
Claude connectorCommunityChecks AI-built UI code against your design tokens and reports drift. Stateless, read-only.
swatchdog keeps an AI build on-brand. Give your agent your design system. Paste your tokens, describe them, or approve a set it proposes and swatchdog deterministically checks generated UI code against them, returning a compact, structured drift report: for each violation, the token axis (color / radius / spacing / type), the value found, the expected token and its value, and the location.
It reads declared styles and tokens, not pixels. It is stateless. Your tokens and code are passed with each call and never stored - and read-only: it reports drift; it does not modify code. Enforcement is your agent's job; the source of truth is yours; swatchdog is the instrument.
Works with no key (shared free lane, rate-capped). A one-time $12 personal key (swatchdog.dev) removes the cap in header-capable MCP clients (Claude Code, Claude Desktop, Cursor). The full pack library and hosted suite are at swatchdog.dev.
