Current behavior

The coder agent sets the following env vars in the environment of the user.

• GIT_COMMITTER_EMAIL
• GIT_COMMITTER_NAME
• GIT_AUTHOR_EMAIL
• GIT_AUTHOR_NAME

Why can this be problematic?

It could be possible that users have a different email for their coder account that they don't want to leak in git commits or a different user name

Suggested solution

Make it possible to:

• Option A: Disable the setting of these env vars all together
• Option B: Make it possible to customize them
