GAN Skill for Claude Code: Adversarial AI Tool for Idea Refinement

GAN Skill for Claude Code

A Claude Code skill called /gan implements an adversarial AI approach to idea refinement, using alternating Discriminator and Generator roles to critique and evolve concepts through multiple rounds of iteration.

How It Works

The system operates with two alternating roles:

• Discriminator (🔴): Steel-mans your idea first, then systematically attacks it
• Generator (🟢): Concedes valid hits, defends with substance, evolves the idea

Each round builds on all previous rounds with no repetition. The tool was developed through self-iteration where the creator used /gan to stress-test /gan itself, resulting in multiple feature improvements over 20+ rounds.

Features Developed Through Self-Iteration

• ✅ Added forced role selection (/gan d, /gan g)
• ✅ Added intensity modes (hard = pre-mortem, soft = Socratic questions)
• ✅ Added multi-language output (:en, :ja, :ko)
• ✅ Added Reconnaissance Mode (smarter first-round critique)
• ❌ Tried adding explicit "soft Generator" rules — /gan rejected it (the old implicit behavior was actually better)

Every feature was either born from or survived adversarial pressure. The initial version was rough — just a Discriminator that attacks. When the creator ran /gan on its own design, the Discriminator found that "there's no defense, only attack." The Generator responded by adding itself — a role that absorbs the critique, concedes what's valid, and evolves the idea into something stronger.

Installation and Security

Installation takes approximately 30 seconds:

mkdir -p ~/.claude/skills/gan && curl -o ~/.claude/skills/gan/SKILL.md https://raw.githubusercontent.com/GAN-Thinking/gan-skill/main/SKILL.md

The skill is contained in one SKILL.md file with zero permissions — no Bash, no file access, no internet. The creator notes they're not a native English speaker and used Claude to help write the original post, demonstrating the tool's purpose: to make AI work harder for you.
