## Overview

DevFlow is a developer Q&A application: people browse and search questions, filter listings, and submit or edit questions with tags; account creation and sign-in provide identity. The sampled code shows question actions coordinating question/tag persistence, and authentication coordinating account and user lookups. The README is only the generic Next.js starter README, so capabilities such as collections, profiles, community, jobs, answers, votes, and OAuth providers are inferred from the route tree and model names; their runtime connections are not asserted where unsampled.

Main entry points: [`app/(root)/page.tsx`](https://github.com/uchecom/uchecom_devflow/blob/main/app/(root)/page.tsx) (Question Pages), [`lib/actions/question.action.ts`](https://github.com/uchecom/uchecom_devflow/blob/main/lib/actions/question.action.ts) (Question Actions), [`lib/actions/auth.action.ts`](https://github.com/uchecom/uchecom_devflow/blob/main/lib/actions/auth.action.ts) (Credential Actions), [`auth.ts`](https://github.com/uchecom/uchecom_devflow/blob/main/auth.ts) (Auth Configuration)
