Skill3 is a lightweight Java CLI that relearns a technical skill for an AI agent. It discovers documentation sources, scores them for authority and freshness (anchored to a target model's knowledge cutoff), synthesizes them with a local LLM into an Agent Skills SKILL.md, and vets the result with NVIDIA's SkillSpector.
