adversarial-review

adversarial-review is a skill for Claude Code from quaat/autonomous-development. It costs 37 tokens per session (195 once invoked), scanned A, original, MIT.

A read-only review focused on serious risks such as login access, permissions, stored data, database changes, concurrent actions, retries, privacy, and outside services.

In plain words
What is it for?
Use it after normal verification for changes involving authentication, authorization, persistence, migrations, concurrency, retries, data loss, privacy, or external services.
Why use it?
It looks for failure scenarios that ordinary tests or code review may miss, especially where mistakes could expose data or cause loss.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: names the AskUserQuestion tool; mentions Codex.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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 6d 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.

What it actually says

Adversarial review

Use for high-risk changes after ordinary verification and code review.

python3 "${CLAUDE_PLUGIN_ROOT}/scripts/controller.py" set-risk --require-adversarial --reason "$ARGUMENTS"
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/controller.py" codex --phase adversarial

Read the generated adversarial-NN.codex.json. Distinguish concrete failure scenarios from speculation and identify the smallest evidence-backed mitigations. Do not edit product files in this skill.

Changes

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.
