A Claude Code plugin that orchestrates adversarial review loops between Claude Code and OpenAI Codex CLI. Claude writes plans and code; Codex tears them apart. They iterate until convergence.

This plugin adds two slash commands to Claude Code:

Pre-implementation planning with adversarial critique.

1. Claude analyzes your codebase and writes a detailed implementation plan
2. Codex reviews the plan as a pragmatic senior engineer — looking for real bugs, not theoretical nitpicks
3. Claude revises based on feedback
4. Loop continues until Codex approves (or 20 iterations max)
5. Pauses for your approval before any code is written

Post-implementation code review on your current git changes.

1. Captures your git diff
2. Codex reviews for bugs, security issues, and correctness problems
3. Claude autonomously fixes any critical issues found
4. Loop continues until Codex approves (or 20 iterations max)

• Claude Code CLI installed and configured
• OpenAI Codex CLI installed and on your PATH (codex exec must work)

Add the marketplace and install the plugin in Claude Code:

/plugin marketplace add bobby-beckmann/adversarial-review
/plugin install adversarial-review@adversarial-review

The /adversarial-plan and /adversarial-review commands will be available in all projects.

/plugin update adversarial-review@adversarial-review

Codex ends every review with one of:

• APPROVED — no blocking issues, work is acceptable
• NEEDS_REVISION — blocking issues that must be addressed

Reviews are calibrated to be pragmatic. A simple script doesn't get the same scrutiny as a payment system. Convergence typically happens in 2-3 iterations.

Each run creates a unique session directory under .adversarial-review/ in your project root:

.adversarial-review/
  latest -> abcd-efgh-ijkl/       # symlink to most recent session
  abcd-efgh-ijkl/
    plan_v1.md, plan_v2.md, ...   # plan iterations
    review_v1.md, review_v2.md, ... # Codex reviews of each plan
    plan_final.md                  # converged final plan
  mnop-qrst-uvwx/
    diff_for_review.md             # code changes sent for review
    code_review_v1.md, ...         # Codex code review rounds

Previous sessions are preserved. You may want to add .adversarial-review/ to your .gitignore.

• Iteration limit: Edit the commands in commands/ to change from the default 20
• Review prompts: Customize what Codex evaluates by editing scripts/codex-review.sh
• Review stance: The prompts are tuned for pragmatic review — modify them if you want stricter or more lenient feedback
