Skill for legal research on Italian and EU sources: legislation, administrative practice, and case law. Encode a working method, not an opinion: routing to official sources, citations with verifiable references, validity checks including ratione temporis, query minimization for contexts covered by professional secrecy, and concise output by default. The Agent Skills format is an open standard: the skill was created for Claude (claude.ai, Desktop, Cowork, Claude Code) and is reusable in tools that adopt the same format.
