Conventions for the Next.js App Router stack (src/app/<f>/, route handlers, Tailwind, Playwright). Use when adding a page, an API route, a component or a test in this repo.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Next.js stack
Setup: `.uak/stacks/nextjs/STACK.md`. React performance rules: `vercel-react-best-practices` (read one rule file, not all).

| Rule | Why |
|---|---|
| One feature = `src/app/<f>/` + `src/app/api/<f>/` + `src/components/<f>/`; never edit another feature's folder | disjoint claims |
| Server Components by default; `"use client"` only for state, effects or browser APIs | smaller bundles |
| Data from `src/app/api/<f>/route.ts` or server code; external calls with a timeout and a labeled mock (`demo_data: true`) | the demo survives a dead API |
| Shared types and helpers in `src/lib/` belong to their owner: ask with `uak msg ID --kind request` | one writer per contract |
| Dependencies: ask the owner of `package.json`; never commit a lockfile from a feature task | lockfiles go to the human queue |
| Secrets only in `.env.local` (git-ignored), read on the server; never `NEXT_PUBLIC_` for a secret | the scanner blocks them |
| Every data view has loading, empty and error states | reviewers check them |

```bash
bash .uak/bin/q npm run lint && bash .uak/bin/q npx playwright test tests/<f>.spec.ts
```

How to install

The exact contents, by fingerprint
mdr add joahanmorales/upiixia-agentic-kit/stack-nextjs@sha256:5e42142a9c300b16

The line at the top of this page pins the label git:20261015.86234b5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
