Use when drafting a spec/ACs for an app feature, planning or building UI views with filters/search/reports, implementing delete/mutation flows, or reviewing feature work — routes to the cross-project behavioral quality patterns (QP-xx) that recurring consumer-app defects proved necessary (URL reflects view state; deletes define cascade/orphan policy; empty/loading/error states; chevron alignment; double-submit guards...). Patterns become spec ACs by ID and carry copy-ready smoke recipes. Do NOT use for process/lifecycle questions (FLOW_RULES owns those), for stack-specific HOW guidance (CLI skills like app-ui-design own that), or to gate semantically by regex.
