What problem does it solve? Frontend bugs in server-rendered apps often hide in the seams between Mustache templates, route wiring, client bundles, and API responses, and they slip through when reviews focus only on style. This Skill provides a disciplined audit workflow for the Academic Events web/ app that finds real user-facing defects and locks them down with deterministic tests. ## Core Features & Use Cases - Contract Mismatch Detection: Finds mismatches between HTML ids/classes, JS selectors, SSR template variables, route output, and checked-in bundles. - Flow-Level Bug Hunting: Targets query-state hydration, URL sync, login redirects, token persistence, modal/tab state, and datetime normalization issues. - Regression Coverage Pairing: Maps each finding to the right test type (pure helper, jsdom plus VM, spawned route test, or browser pass) under web/tests. - Use Case: When a dashboard filter stops syncing to the URL or a login redirect misbehaves, use this Skill to trace the flow from SSR shell to client boot, prove the defect, and add a failing-then-passing test. ## Quick Start Review the week page frontend for query-state and date rendering bugs, then add matching regression tests under web/tests.
