Correctness And Error Handling

This is a systematic code auditor from Cognitedata that hunts down error handling gaps in your app. It walks through async data flows, checks what happens when API calls fail, and fixes issues in place rather than just reporting them. The workflow is opinionated: it maps your data sources by reading hooks, contexts, and API services first, then validates error states, loading states, and empty states across the UI. It's built for apps using the Cognite Data Fusion SDK but the approach works for any React app with async dependencies. Use it when you're hardening production code or inheriting a project where you suspect error cases were glossed over.
