## Commit attribution

Codex can add a [git trailer](https://git-scm.com/docs/git-interpret-trailers) to
generated commit messages so commits make Codex's involvement explicit. This
behavior is gated by the `codex_git_commit` feature flag; the top-level
`commit_attribution` setting is only used when that feature is enabled.

Add the following to `~/.codex/config.toml`:

```toml
commit_attribution = "Codex <noreply@openai.com>"

[features]
codex_git_commit = true
```

When enabled, Codex appends a `Co-authored-by:` trailer using the configured
attribution value. If `commit_attribution` is omitted, Codex uses
`Codex <noreply@openai.com>`. Set `commit_attribution = ""` to disable the
trailer while leaving the feature flag enabled.
