What problem does it solve? After fixing a bug, the same root-cause pattern often exists in other components, but developers rarely check. This Skill mechanically extracts the anti-pattern from a fix commit and scans the entire design system for matching occurrences, then batches the related fixes. ## Core Features & Use Cases - Root-cause extraction: Reads the last fix commit message and diff to derive a grep-able anti-pattern (token leaks, magic numbers, API misuse, a11y gaps, asymmetric icon sizing). - DS-wide detection: Runs static grep or Playwright-based visual scans across the design system source to build a candidate list with file and line evidence. - Authority-gated batch fixing: Classifies candidates into auto-fix, engineering-judgment, backlog, or human-decision paths, then verifies with TypeScript compilation, unit tests, and visual scans. - Use Case: After fixing a padding formula bug in one component, invoke the scan to find the same formula error in five other components, fix them all, and add a canonical hook to prevent regression. ## Quick Start Ask the AI to run /scan-similar-bugs after your fix commits to find and fix the same bug pattern across the whole design system.
