What problem does it solve? When a feature "almost works" or a dev server just started, developers lack a systematic way to confirm the entire user story actually functions across every layer — UI, API routes, data sources, and response rendering — instead of checking each piece in isolation. ## Core Features & Use Cases - Story Inference: Reads recently edited files, routes, and environment files to infer the exact user story being built before running any checks. - Layer-by-Layer Evidence Gathering: Inspects browser console, dev server terminal, runtime logs, and environment variables, reporting findings at each boundary. - Data Flow Tracing: Walks the path from UI trigger through client request, API handler, external dependencies, and back to rendered response, catching common breaks like missing awaits, wrong HTTP methods, and absent env vars. - Use Case: After implementing a new form that submits to an API route backed by a database, ask for a full verification to confirm the browser renders, the request reaches the handler, the database call succeeds, and the response renders correctly. ## Quick Start Ask the assistant to verify the full flow end to end for the feature you just built.
