About

skill-upper helps authors set up, run, and interpret evaluations for Agent Skills using the skill-up CLI. It installs a Skill into a real agent engine, runs prompts per test case, then grades results via rules, LLM judges, or custom scripts and produces a report. A developer uses it to add evals or regression cases, write eval.yaml and case.yaml, and verify a Skill before shipping.

  • Runs skill-up CLI evals for Agent Skills across engines like Claude Code and Codex
  • Scaffolds eval.yaml/case.yaml, authors judges, and produces reports
  • Migrates from Anthropic evals.json to the skill-up format
