Drag-and-Drop QA — Coordinate-Based Verification

Codex Compatibility

When running this skill in Codex, translate Claude Code-only primitives before acting: AskUserQuestion -> chat/request_user_input, TodoWrite -> update_plan, Task/TaskCreate/TeamCreate/SendMessage -> spawn_agent/send_input/wait_agent when available and allowed, and EnterPlanMode/ExitPlanMode -> a concise chat plan plus explicit approval. Resolve Read/Write/Edit/Bash/WebSearch/WebFetch to Codex file/shell/web tools, and map ~/.claude/... paths to ~/.agents/... or ~/.codex/... unless the task explicitly targets Claude Code.

Agent browser tools often report ref-based drag as successful even when custom DnD libraries (dnd-kit, react-dnd, native HTML5 DnD wrappers) drop on the wrong target. Treat any drag <sourceRef> <targetRef> success as unverified unless the rendered state proves the move landed.

When to apply

Load this protocol whenever browser-driven verification touches drag-and-drop:

• dnd-kit DragOverlay / SortableContext flows
• Kanban / list reorder
• File / item drop zones
• Tree / outline reparenting
