Run each rule
Each question is a lint rule scored 1 (fail) to 3 (pass), mirroring how a code linter flags violations by severity.

How it works
Weight by risk
Duplicate components and hardcoded values weight higher since they compound fastest as the product grows.
Report the violations
The result lists which rules failed or warned, in the order they should be fixed.
Frequently asked questions
Is this an actual automated linter?
No — there is no file-scanning backend. It structures a manual design review into the same pass/warn/fail format a code linter uses, so issues are easy to track and fix.
Why model this after code linting?
Code linters catch small inconsistencies before they compound into technical debt. The same discipline applied to design catches drift before it becomes expensive to fix.
What is the highest-weighted rule?
Duplicate components and hardcoded values, since both directly undermine the reusability a design system is meant to provide.
How often should I run this?
Before each release, similar to running a linter in CI before merging code.

Some Figma plugins can flag literal duplicate layers or unused styles inside a file. Design Lint applies a broader, weighted rule set based on your own review, without needing file access.
