Use when formalizing contracts, legislation, regulations, policies, or compliance logic into computable form. Triggered when users need to encode legal rules, validate formalized law, generate web apps from legal logic, or translate natural language legal text into formal specifications. The skill covers L4 syntax, type system, pattern matching, validation with jl4-cli, and the complete workflow from analysis to deployment.
