Hi @dominicbytes,
I appreciate your enthusiasm to help out the project, but I would encourage you to please take a moment to review our AI Policy.
While in this case, a legitimate problem was identified, this really should have been a 4 or 5 line change vs the 82 line diff we have at the time of reviewing.
Please see my review comments and apply my requested feedback, and we can go ahead and get this merged.

These 3 lines of code here and the above import subprocess are really the only section of this 80~ line diff that are really needed, as the return code was basically discarded from the previous code was discarded, allowing this check to pass even if dotnet format returned an error code, which is a valid problem.

Reduced to the exit-status fix plus require_serial. Removed the test file and CI step; restored existing path handling. Local process checks and repository hooks pass.

Injection (CWE-78): Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Pass repository paths as an argument vector.
shell=True allows shell metacharacters in repository filenames to execute commands and breaks paths containing spaces. Keep each path as a separate argument.
Proposed fix
- path: " ".join([f for f in sys.argv[1:] if os.path.commonpath([f, path]) == path])
+ path: [f for f in sys.argv[1:] if os.path.commonpath([f, path]) == path]

Confirmed: shell interpretation already exists in the original os.system call. The argument-vector fix was removed per maintainer review to keep this PR focused on exit status. Leaving this finding open for the maintainer to decide whether to include that fix here or separately.

@dominicbytes, acknowledged. The shell=True behavior predates this pull request. The command-injection concern remains valid, but it is outside the current exit-status scope. I will leave the finding open for maintainer disposition.

Learning: In `misc/scripts/dotnet_format.py`, shell interpretation existed before pull request `#1397` through `os.system`. Maintainer review removed the argument-vector change from pull request `#1397` to keep the change focused on propagating `dotnet format` exit status. The command-injection hardening can be handled in a separate change.

@dominicbytes & @coderabbitai,
I think the previous version of this line was fine as it was:
result = subprocess.run(["dotnet", "format", path, "--include", *files]).
My review comment for this section was more so to mark this section as what to keep and indicate the portion of it I was interested in merging.
I don't really see a reason to add shell=True here just to match the exact behavior of os.system. While I am less concerned about security / stability concerns here since we already have safeguards in place that would mitigate the occurrence of file names accidentally breaking this code, as well as mitigation against bad actors exploiting it in practice... It'd be best not to reintroduce a vulnerability just for the sake of exactly replicating the original behavior. So I'd have to agree with Coderabbit here.

@Arctis-Fireblight, agreed. The argument-vector form is the correct implementation here.
files must remain a list, and the invocation should use:
subprocess.run(["dotnet", "format", path, "--include", *files], check=False)This preserves exit-status propagation and avoids shell interpretation. The finding remains open until that change is applied.

Learning: For Redot-Engine/redot-engine pull request `#1397`, the intended `misc/scripts/dotnet_format.py` implementation is `subprocess.run(["dotnet", "format", path, "--include", *files], check=False)`. Do not use `shell=True` merely to reproduce the former `os.system` behavior. Keep `files` as a list so paths are passed as individual command arguments.
