Why not take the best of both worlds? Use pre-commit hooks for client-side validation, and run the same checks in CI as well. I’ve been using this setup for years without any issues.

One key requirement in my setup is that every hook is hermetic and idempotent. I don’t use Rust in production, so I can’t comment on it in depth, but for most other languages—from clang-format to swift-format—I always download precompiled binaries from trusted sources (for example, the team’s S3 storage). This ensures that the tools run in a controlled environment and consistently produce the same results.
