0. Summary

• Verdict: MINOR SUGGESTIONS ✏️

Fixes the /environment_variables endpoint in core/services/commander/main.py by wrapping os.environ (an os._Environ mapping, not a plain dict) in dict(...) so FastAPI can serialize it, and tightens the return annotation from Any to Dict[str, Any].

6. Code Quality & Style

• 6.1 [nit] core/services/commander/main.py:266 — os.environ values are always str, so Dict[str, str] is strictly more accurate than Dict[str, Any] and would give call sites better type information without changing runtime behavior.

Good catch. It was showing Could not get environment variables: [object Object]. on the frontend as well.
