codex review

Runs a review of changes via the CLI.

codex review runs a code review non-interactively from the command line, i.e. without opening a running TUI session. According to the docs, you choose exactly one review target: either --uncommitted (staged, unstaged, and untracked changes), --base <branch> (diff against a base branch), --commit <SHA> (changes from a specific commit), or your own review instructions as a free-text PROMPT (also readable from stdin with -) — according to the docs, these options are mutually exclusive. --title sets the displayed commit title in the review summary, but only works together with --commit. There's also --strict-config, which triggers an error if config.toml contains unknown fields. Distinct from the standalone codex review call is the slash command /review, which according to the Codex source code is used within an already-running interactive session and also accepts instructions as an inline argument there.
