+- clarify only the assumptions that change the package design
+- do not add speculative features, generic configurability, or decorative structure
+- when editing an existing skill, touch only files that directly serve the requested change
+- connect each meaningful change to a check: route evidence, sample run, resource-boundary check, governance check, or reviewer note
