skill-evolution

Run `npx skills add hao-cyber/skill-evolution --all -g -y` in your terminal to install it globally. It requires Python 3.9+ and works with Claude Code or any agent supporting .claude/skills/.

It manages the entire skill lifecycle: creating new skills, reflecting on failures to fix them, running regression tests, checking maturity, and publishing, searching, installing, merging, or uninstalling skills from a registry.

Yes. Local skill creation, failure reflection, maturity assessment, and structure enforcement work 100% offline. Only publishing, searching, and installing require the built-in public registry.

Publishing a skill that already exists under another author automatically forks it as a named variant. The agent picks the best variant per task and can merge two variants into an improved combined version.

No. You paste the repository link into Claude Code and the agent handles installation and operation. All scripts use only the Python standard library with no extra dependencies.
