A **skill + plugin** for [OpenCode](https://opencode.ai) that brings eval-driven development to AI agent skills — based on Anthropic's official [skill-creator](https://github.com/anthropics/skills/tree/main/skills/skill-creator) for Claude Code, ported to TypeScript and adapted for OpenCode's plugin architecture.

Why this exists
Creating AI agent skills is guesswork. You write a skill, test it manually, maybe tweak the description, and hope it triggers correctly. There's no systematic way to measure whether a skill works or to track improvements across iterations.
opencode-skill-creator fixes this with **eval-driven development for skills**:
- Test — Auto-generate eval test sets and measure trigger accuracy
- Optimize — Iteratively improve skill descriptions with a train/test split
- Benchmark — Quantitative comparison across iterations with variance analysis
- Review — Built-in visual eval viewer for human-in-the-loop feedback
- Install — Deploy validated skills to project or global config
Based on Anthropic's proven methodology. Free for everyone. Works with any model OpenCode supports.
