Adversarial Spec — Testing skill for Claude Code

adversarial-spec

A Claude Code plugin that iteratively refines product specifications through multi-model debate until consensus is reached.

**Key insight:** A single LLM reviewing a spec will miss things. Multiple LLMs debating a spec will catch gaps, challenge assumptions, and surface edge cases that any one model would overlook. The result is a document that has survived rigorous adversarial review.

**Claude is an active participant**, not just an orchestrator. Claude provides independent critiques, challenges opponent models, and contributes substantive improvements alongside external models.

Quick Start

# 1. Add the marketplace and install the plugin
claude plugin marketplace add zscole/adversarial-spec
claude plugin install adversarial-spec

# 2. Set at least one API key
export OPENAI_API_KEY="sk-..."
# Or use OpenRouter for access to multiple providers with one key
export OPENROUTER_API_KEY="sk-or-..."

# 3. Run it
/adversarial-spec "Build a rate limiter service with Redis backend"
