Use this skill to statically review TypeScript static-enforcement policy: strict-family flag policy and silent loosening across a program graph (strict defaults true since TypeScript 6.0), per-package divergence, typed-lint rule selection and Project Service configuration, editor-versus-CI parity, `@ts-ignore`/`@ts-expect-error`/lint-disable suppression policy, lint-versus-typecheck duplication, and the typescript-eslint supported-version window. Reads configuration and lint config only; it never runs the linter or the compiler.
