I have a code review agent and it issued the following command:

git --no-pager diff --merge-base origin/HEAD HEAD --name-status

And the response that it captured is:

tus                                                                             M       src/foo/bar.cpp

There this "tus" at the beginning is actually from the "--name-status" getting included in the output. This confuses the AI agent where it says: "The output seems truncated. Let me try again with a different approach." and then it tries:

git --no-pager diff --merge-base origin/HEAD HEAD --name-status 2>&1

Which has the following captured output:

tus 2>&1                                                                        M       src/foo/bar.cpp

And again it says "The output looks like it might be getting cut off at the start. Let me try a different approach ..."
