Skill Evaluator
Evaluate Agent Skills against agentskills.io specification and best practices.
Core Philosophy
Good Skill = Expert-only Knowledge − What the LLM Already Knows
| Knowledge Type | Treatment | Example |
|---|---|---|
| Expert (LLM doesn't know) | Keep — this is value | "mediabox not cropbox for PDF size" |
| Activation (LLM may forget) | Keep if brief | "Always validate XML before packing" |
| Redundant (LLM knows) | Delete — token waste | "What is a PDF file" |
