When users are double-clicking buttons or asking "did that work?" you've got a feedback visibility problem. This skill diagnoses the issue through Disney animation principles like anticipation, follow through, and staging. It's surprisingly practical: if feedback appears outside the user's focus area or vanishes in under a second, they'll miss it. The fix is usually combining multiple signals (color plus motion plus position) and keeping everything near the trigger point. Includes a checklist for the 100ms acknowledgment rule and code patterns for success pulses and error shakes. Best part is the troubleshooting question: can users tell if their action succeeded without reading any text?
