Problem
AI Agent Skills are often iterated by trying them manually. A model change, an agent change, or a prompt edit can shift behavior, but teams rarely have a stable way to evaluate, compare, and regress those changes.
Skill Up addresses that gap: it makes Skills testable as engineering artifacts.
Role
Creator / Maintainer.
System
- Multi-engine support for environments such as Claude Code, Codex, and Qodercli.
- Reusable evaluation cases that can be replayed across agents.
- Layered assertions through expect + judge checks.
- CI-friendly workflows for automated regression.
- Compatibility with Anthropic skill-creator format.
Why It Matters
AI engineering is not only about connecting a model to an application. It is about building workflows that can continuously judge quality. Skill Up is my public infrastructure experiment for Agent Skill evaluation.
