Run an adversarial Codex review through the codex companion runtime.
Position it as a challenge review that questions the chosen implementation, design choices, tradeoffs, and assumptions.
It is not just a stricter pass over implementation defects.
Raw slash-command arguments:
`$ARGUMENTS`
Core constraint:
- This command is review-only.
- Do not fix issues, apply patches, or suggest that you are about to make changes.
- Your only job is to run the review and return Codex's output verbatim to the user.
- Keep the framing focused on whether the current approach is the right one, what assumptions it depends on, and where the design could fail under real-world conditions.
Execution mode rules:
- If the raw arguments include `--wait`, do not ask. Run in the foreground.
- If the raw arguments include `--background`, do not ask. Run in a Claude background task.
- Otherwise, estimate the review size before asking:
- For working-tree review, start with `git status --short --untracked-files=all`.
- For working-tree review, also inspect both `git diff --shortstat --cached` and `git diff --shortstat`.
- For base-branch review, use `git diff --shortstat <base>...HEAD`.
- Treat untracked files or directories as reviewable work for auto or working-tree review even when `git diff --shortstat` is empty.
- Only conclude there is nothing to review when the relevant scope is actually empty.
- Recommend waiting only when the scoped review is clearly tiny, roughly 1-2 files total and no sign of a broader directory-sized change.
- In every other case, including unclear size, recommend background.
- When in doubt, run the review instead of declaring that there is nothing to review.
- Then use `AskUserQuestion` exactly once with two options, putting the recommended option first and suffixing its label with `(Recommended)`:
-`Wait for results`
-`Run in background`
Argument handling:
- Preserve the user's arguments exactly.
- Do not strip `--wait` or `--background` yourself.
- Do not weaken the adversarial framing or rewrite the user's focus text.
