Adversarial Code Reviewer

An adversarial review skill that forces Claude into three hostile reviewer personas so 'LGTM' is never an option.

Dev & CodingBeginner★ 28,022⑂ 3,926AI score 9/10Last updated: Aug 30, 2026

What it does

Breaks the self-review monoculture where the reviewer shares the author's mental model.

  • Three mandatory personas: Saboteur (tries to break it in production), New Hire (maintainability in 6 months), Security Auditor (OWASP-informed checklist)
  • Mandatory findings: each persona must surface at least one issue — no rubber stamps
  • Severity promotion: anything caught by 2+ personas moves up a level (NOTE→WARNING→CRITICAL)
  • Clear verdict: BLOCK / CONCERNS / CLEAN with merge guidance
  • Requires reading the full file and project conventions (CLAUDE.md, lint configs), not just changed lines

Who it's for

  • Solo devs and small teams merging PRs without a human reviewer
  • Anyone frustrated by AI that only praises the code it just wrote
  • Backend/fullstack engineers touching auth, payments, or data access
  • Post-marathon coding sessions when your own judgment is fatigued

Examples

  1. /adversarial-review — reviews staged/unstaged changes; falls back to the last commit if both are empty.
  2. /adversarial-review --diff main...HEAD — full branch review right before merging a PR, ending in a BLOCK/CONCERNS/CLEAN verdict.
  3. /adversarial-review --file src/auth.ts — reads an entire auth file hunting for IDOR, hardcoded secrets, and missing role checks.

Let Claude do it — paste this into Claude Code

Install the skill I found on AI Skill Mart.
Copy the .gemini/skills/adversarial-reviewer folder from the GitHub repo alirezarezvani/claude-skills into my ~/.claude/skills/adversarial-reviewer/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/alirezarezvani/claude-skills.git && mkdir -p ~/.claude/skills && cp -r claude-skills/.gemini/skills/adversarial-reviewer ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/alirezarezvani/claude-skills.git
  3. Create the skills folder if needed: mkdir -p ~/.claude/skills
  4. Copy just this skill: cp -r claude-skills/.gemini/skills/adversarial-reviewer ~/.claude/skills/
  5. Restart Claude Code, open a git repository, then run /adversarial-review or ask "use the adversarial-reviewer skill on my current changes".
  6. No extra dependencies are needed, but you must run it inside a git repo so the skill can read diffs.
