adversarial-review

adversarial-review is a command for coding agents from Vit129/agy-plugin-cc. It costs 15 tokens per session (721 once invoked), scanned A, a copy of adversarial-review, MIT.

A command that asks agy to challenge an implementation's approach, design choices, trade-offs, and assumptions. It performs a review without changing the code.

In plain words
What is it for?
Use it for a working-tree or branch review, including foreground, background, and dry-run modes, when you want critical feedback before accepting an approach.
Why use it?
It helps reveal weaknesses in the chosen solution that a defect-focused review might miss.

Command

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Token cost

What it costs to keep this loaded

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.

Security

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 5d 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.

Origin

This is a copy

83% identical to adversarial-review — 37 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 agy review. Position it as a challenge review that questions the chosen implementation, design choices, tradeoffs, and assumptions — not just a stricter pass over 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 agy'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 --dry-run, do not ask. Run in the foreground — it only prints the resolved options and available models, no review is performed.
  • 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, run git status --short --untracked-files=all.
    • Also inspect git diff --shortstat --cached and git diff --shortstat.
    • For base-branch review, use git diff --shortstat <base>...HEAD.
    • Treat untracked files as reviewable work 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 review is clearly tiny (roughly 1–2 files).
    • In every other case, recommend background.
  • 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.

Foreground flow:

  • Run:
node "${CLAUDE_PLUGIN_ROOT}/scripts/agy-companion.mjs" adversarial-review "$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 Bash in the background:
Bash({
  command: `node "${CLAUDE_PLUGIN_ROOT}/scripts/agy-companion.mjs" adversarial-review "$ARGUMENTS"`,
  description: "agy adversarial review",
  run_in_background: true
})
  • Do not wait for completion in this turn.
  • After launching the command, tell the user: "agy adversarial review started in the background. Check /agy:status for 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.
