The tool creates a temporary read-oriented Git wrapper for the nested Codex process. It allows review commands such as git diff, git show, git status, and git ls-files, and blocks write or remote update commands such as git push, git commit, and unsupported Git subcommands.
When modelApiKey is supplied, this plugin writes config.toml and auth.json under a temporary CODEX_HOME for the review process only. It does not replace the user's existing ~/.codex files.
