Improvement Evaluator

Measures whether a Skill actually makes AI perform better on real tasks.

When to Use

• Verify that a SKILL.md change improves AI task execution (not just document structure)
• Run a task suite against a candidate SKILL.md and compare with baseline
• Get execution_pass_rate as a concrete quality metric
• Run standalone evaluation on current SKILL.md to discover baseline failures

When NOT to Use

• 只想检查 SKILL.md 结构质量 → use improvement-learner
• 只想给候选打分 → use improvement-discriminator
• 跑全流程 → use improvement-orchestrator
