Build a resolved import DAG for `src/**/*.ts` and `src/**/*.tsx`, identify safe barrel opportunities, conservatively add or extend `index.ts` barrels without introducing cycles, and merge or collapse imports. Use when refactoring TypeScript imports in this repo or when the user asks to reduce import fan-out under `src/`.

Scans TypeScript and TSX code for attempts to bypass the type system, including `as any`, double-casts through `unknown`, redundant assertions, suspicious inline `ReturnType` and `Awaited<ReturnType>` usage, and single-use local wrapper aliases. Use when auditing `src/` for unsafe typing patterns or cleaning up type escapes.
