handoff-spec
Agent skill fromOwl-Listener/designer-skills
Write the implementation handoff — measurements, behaviours, assets, states, and edge cases. Use when engineering picks up the work. For verifying the result afterwards use `design-qa-checklist`; for reusable library components use `component-spec` (design-systems).
