What problem does it solve? Compilation success and green unit tests do not prove a Blazor UI actually works in the browser. This Skill performs a read-only, end-to-end audit of a Blazor or Razor component library, tracing rendering, state notifications, CSS/markup contracts, JavaScript interop, disposal, packaged assets, and demo topology to produce severity-ranked findings with file:line evidence. ## Core Features & Use Cases - Full behavioral chain tracing: Maps DOM events through handlers, state mutation, notifications, projection rebuilds, render requests, and persistence to find broken links. - Interop and lifecycle pairing checks: Verifies attach/detach, listener add/remove, DotNetObjectReference create/dispose, and observer start/stop pairs, plus RenderTree sequence stability across transitions like Undo/Redo. - Package and demo verification: Confirms the demo consumes the current source, package, or bundle and that the browser loaded the exact artifact under test. - Use Case: bUnit tests pass but drag-and-drop fails in the browser; the audit checks hit-test geometry, producer/consumer reachability, and real operation commits instead of trusting DOM presence. ## Quick Start Ask the agent to audit your Blazor component library end to end, covering components, CSS, JavaScript interop, state notifications, packaging, and real-browser behavior, and to return severity-ranked findings with file:line evidence.
