Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00013 | $0.00883 |
| Opus 5 | $0.00006 | $0.00441 |
| Sonnet 5 | $0.00003 | $0.00177 |
| Haiku 4.5 | $0.00001 | $0.00088 |
Grade A, and why
adversarial-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
92% identical to adversarial-review — 10 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Run an adversarial Codex review through the shared plugin 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 Grok 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 --cachedandgit 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 --shortstatis 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.
- For working-tree review, start with
- Then use
AskUserQuestion(Grok:ask_user_question) exactly once with two options, putting the recommended option first and suffixing its label with(Recommended):Wait for resultsRun in background
Argument handling:
- Preserve the user's arguments exactly.
- Do not strip
--waitor--backgroundyourself. - Do not weaken the adversarial framing or rewrite the user's focus text.
- The companion script parses
--waitand--background, but Grok'srun_terminal_command(..., background: true)(Claude-compatibleBash(..., run_in_background: true)) is what actually detaches the run. /codex:adversarial-reviewuses the same review target selection as/codex:review.- It supports working-tree review, branch review, and
--base <ref>. - It does not support
--scope stagedor--scope unstaged. - Unlike
/codex:review, it can still take extra focus text after the flags.
Foreground flow:
- Run:
node "${GROK_PLUGIN_ROOT:-$CLAUDE_PLUGIN_ROOT}/scripts/codex-companion.mjs" adversarial-review "$ARGUMENTS"
- Return the command stdout verbatim, exactly as-is.
- Do not paraphrase, summarize, or add commentary before or after it.
- Do not fix any issues mentioned in the review output.
Background flow:
- Launch the review with
Bashin the background:
Bash({
command: `node "${GROK_PLUGIN_ROOT:-$CLAUDE_PLUGIN_ROOT}/scripts/codex-companion.mjs" adversarial-review "$ARGUMENTS"`,
description: "Codex adversarial review",
run_in_background: true
})
- Do not call
BashOutputor wait for completion in this turn. - After launching the command, tell the user: "Codex adversarial review started in the background. Check
/codex:statusfor progress."
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

adversarial-review is a command published in the GitHub repository jinxlzc/grok-codex-plugin (1 stars, last pushed 26d ago), licensed Apache-2.0. It adds 13 tokens to every session and 883 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 92% identical to adversarial-review, differing in 10 lines, and is treated as a copy.
