What problem does it solve? Writing YON (YounndAI Object Notation) documents by hand is error-prone: strict separator rules, required fields per tag, profile and format choices, and block encoding constraints all must be satisfied for output to parse. This Skill guides an agent to create, generate, or convert content into syntactically valid, roundtrip-safe YON. ## Core Features & Use Cases - Prose-to-YON Conversion: Maps natural language constraints ("must", "never", "should") to @RULE levels while preserving hedging and uncertainty verbatim. - Decision Gates: Structured selection of profile (core, decl, exec, audit, cognitive, agent), format (canon, min, ultra), and document kind before writing. - Validation Checklist: Built-in verification of @DOC placement, @BEGIN/@END pairing, @MAP quoting, and required fields per tag. - Use Case: Convert a messy prose API policy ("all calls must have auth tokens, premium users get 500/min") into a parseable kind=rule YON document with @RULE, @MAP, and @STAMP records. ## Quick Start Convert this rate limiting policy into a YON rule document using the decl profile and min format.
