• obra/superpowers — brainstorming, systematic-debugging, writing-plans, and receiving-feedback trace back to this collection
• blader/humanizer — humanizer is maintained by @blader
• karpathy/autoresearch — autoresearch applies Karpathy's autonomous iteration principles
• anthropics/claude-plugins-official — playground originated from Anthropic's official plugin collection
