Create, audit, test, and improve portable Agent Skills with evidence-backed instructions, progressive disclosure, risk-based evaluations, and release checks. Use when authoring a new SKILL.md, improving an existing skill, designing or grading evaluations, diagnosing weak trigger behavior, or synchronizing a skill across repositories. Also activate when a workflow should become a reusable skill or a skill must improve itself without making unsupported quality claims. This is the authoritative OKHP3 authoring and skill-evolution workflow.
