Create, test, benchmark, and autonomously optimize custom Claude Code skills via category-aware design, gotchas-driven development, eval prompts, performance analysis, and iterative mutation on test inputs with binary scoring and failure reflection.
npx claudepluginhub leejuoh/claude-code-zero --plugin skill-creator-proAutonomously optimize any Claude Code skill by running it repeatedly, scoring outputs against binary evals, mutating the prompt, and keeping improvements. Based on Karpathy's autoresearch methodology with reflection-driven mutation, confidence scoring, and structured session archives. Use when: optimize this skill, improve this skill, run autoresearch on, make this skill better, self-improve skill, benchmark skill, eval my skill, run evals on, autoresearch, auto-optimize. Do NOT use for: creating skills from scratch (use skill-creator-pro), description/trigger optimization (use skill-creator-pro Phase 5), or one-off manual improvements.
Create new skills, modify and improve existing skills, and measure skill performance with category-aware design, gotchas-driven development, and progressive disclosure coaching. Use when users want to create a skill from scratch, update or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, optimize a skill's description for better triggering accuracy, or get guidance on skill architecture and design patterns. Also trigger when someone mentions "make a skill", "create a command", "skill for X", "improve my skill", "turn this into a skill", or wants to capture a workflow as a reusable skill.
