During October 2025, Ali Motahari focused on improving code quality in the TanStack/query repository by addressing a bug in the no-unstable-deps ESLint rule. He enhanced the rule to correctly recognize useQueries hooks that utilize the combine property, preventing false positives that previously affected code analysis. Ali introduced a dedicated helper function, hasCombineProperty, and developed targeted unit tests to ensure the fix remains robust against future changes. His work relied on JavaScript and TypeScript, leveraging skills in ESLint and testing to deliver a precise, maintainable solution that strengthens lint rule reliability for React Query codebases.
