no-unknown-token

The agent-era rule: models fabricate plausible token names (--color-primary-500 in a system that stops at --color-primary), and humans typo them. Any var(--x) not found in the token set is flagged, with a did-you-mean by edit distance.

✖ Unknown token --color-primry — did you mean --color-primary?
  • Not flagged: custom properties defined in the same file (component-local vars), --tw-* (Tailwind internals), names matched by allow globs — the escape hatch for runtime-injected vars like --shiki-* or next/font variables.
  • Default severity: error. This rule has no legitimate steady-state violations: either the token should exist, or the name belongs in allow.
