Worked on targeted improvements across TanStack/router and TanStack/config, focusing on documentation and configuration management. Enhanced the TanStack/router repository by updating the cloning workflow documentation, replacing degit with gitpick to streamline and stabilize project setup for contributors. In TanStack/config, completed a migration of the ESLint configuration to the deprecated @stylistic/eslint-plugin-js, updating related dependencies in pnpm-lock.yaml and pnpm-workspace.yaml, and adjusting imports to ensure compatibility. Documented these changes with a minor version bump using a changeset. Leveraged skills in JavaScript, YAML, and version control to improve tooling consistency and reduce maintenance risk across the monorepo environment.
