I ported Anthropic's official skill-creator from Claude Code to OpenCode — now you can create and evaluate AI agent skills with any model

Hey r/LocalLLaMA - I open-sourced a tool that brings eval-driven development to AI agent skills. It's based on Anthropic's official skill-creator for Claude Code, but rewritten in TypeScript to work with OpenCode (which s 300+ models including local ones). The problem: creating skills for AI agents is trial-and-error. You write a skill, test it manually, and hope it triggers on the right prompts. There's no systematic way to measure if a skill works.
