# CLAUDE.md — Scrum4Me

Desktop-first Scrum-app voor solo developers en kleine teams. Hiërarchie: product → PBI → story → taak. Zie [README.md](./README.md) voor setup.

---

## Orientatie

| Bestand | Waarvoor |
|---|---|
| `docs/INDEX.md` | Gegenereerde index van alle docs — begin hier |
| `docs/specs/functional.md` | Acceptatiecriteria, user flows |
| `docs/architecture.md` | Breadcrumb → 6 topische arch-bestanden |
| `docs/backlog/index.md` | Implementatievolgorde, "done when"-criteria |
| `docs/api/rest-contract.md` | REST API contract voor Claude Code |
| `docs/design/styling.md` | **Lees vóór elk component** — MD3-tokens, shadcn |
| `docs/plans/<key>-*.md` | Implementatieplan per milestone |
| `docs/adr/` | Architecture Decision Records — tech-keuzes (base-ui vs Radix, sort-order, demo-policy, …) |
| `docs/manual/` | 7-delige gebruiks- en operationele handleiding (workflow, git, docker, troubleshooting) |
| `docs/architecture/` | 6 topische architecture-bestanden (data-model, auth, sprint-execution, …) — uitwerking van `docs/architecture.md` |

## Hoe werk vinden

**Track A — MCP (aanbevolen):**
1. Branch aanmaken: `git checkout -b feat/<batch-slug>` — nog **geen** `gh pr create`
2. `mcp__scrum4me__get_claude_context` → pak de next story
3. Voer taken uit in `sort_order`; update status per taak
4. Lees het relevante patroon en styling vóór je begint
5. Verifieer: `npm run verify && npm run build` — `verify` = lint + typecheck + test
6. Commit per laag: `git add -A && git commit` — **geen** `git push` — zie [docs/runbooks/branch-and-commit.md](./docs/runbooks/branch-and-commit.md)
7. Herhaal stap 2–6 per story; branch blijft dezelfde
8. Queue leeg → `git push -u origin <branch>` + `gh pr create`

**Track B — manueel:**
1. Lees taak in `docs/backlog/index.md`
2. Zoek spec in `docs/specs/functional.md`
3. Lees patroon + styling → bouw → verifieer → vraag bevestiging → commit

## Hardstop regels

- **Styling:** nooit `bg-blue-500`; altijd MD3-tokens (`bg-primary`, `bg-status-done`, …)
- **UI:** gebruik `@base-ui/react` met `render`-prop, niet Radix `asChild`
- **Push:** commits accumuleren lokaal per taak (`git add -A && git commit`); push + PR pas bij lege queue of na expliciete gebruikersbevestiging — zie [branch-and-commit.md](./docs/runbooks/branch-and-commit.md)
- **Demo:** drie lagen — proxy.ts + server action + UI disabled knop
- **Enum:** DB UPPER_SNAKE ↔ API lowercase — uitsluitend via `lib/task-status.ts`
- **Foutcodes:** 400 = parse-fout, 422 = Zod-validatie, 403 = demo-token
- **Server/client grens:** `*-server.ts` bevat DB/node-only; nooit importeren in client component
- **Worker/jobs:** `ClaudeJob` queue (`QUEUED → CLAIMED → RUNNING → DONE|FAILED|SKIPPED`); MCP-worker claimt via `wait_for_job` en sluit met `update_job_status` — zie [worker-idempotency.md](./docs/runbooks/worker-idempotency.md)
- **Model/mode per ClaudeJob:** kind-default → product → job-snapshot → `task.requires_opus`. Resolver in `scrum4me-mcp/src/lib/job-config.ts` (en gespiegeld in `lib/job-config.ts`) — zie [job-model-selection.md](./docs/runbooks/job-model-selection.md)
- **Deployment:** `npm run verify && npm run build` vóór elke PR. Selectieve deploy-controle (labels + path-filter): zie [docs/runbooks/deploy-control.md](./docs/runbooks/deploy-control.md)

## Env vars

```bash
DATABASE_URL=""    # postgresql://...
DIRECT_URL=""      # pooler-bypass voor LISTEN/NOTIFY
SESSION_SECRET=""  # min 32 chars
CRON_SECRET=""     # Bearer-secret /api/cron/*
```

Volledig schema: `lib/env.ts`. Canonieke lijst: `.env.example` — bevat ook web-push (`VAPID_*`, `INTERNAL_PUSH_SECRET`), Sentry (`SENTRY_*`) en optioneel `ANTHROPIC_API_KEY`.

---

## MCP & cron

- **MCP-server (extern):** standalone Node-proces in `~/Development/scrum4me-mcp/` — Prisma-schema gesynced via `sync-schema.sh`. 30+ tools (`get_claude_context`, `wait_for_job`, `update_task_status`, …)
- **Cron (vercel.json):**
  - `/api/cron/expire-questions` — dagelijks 04:00 UTC
  - `/api/cron/cleanup-agent-artifacts` — dagelijks 03:00 UTC
- **Realtime:** SSE op `/api/realtime/*`, gevoed door PostgreSQL `LISTEN`/`NOTIFY` op kanaal `scrum4me_changes` (vereist `DIRECT_URL` voor pooler-bypass)

## Scrum-terminologie

PBI (niet: Feature/Epic) · Story (niet: Ticket) · Sprint Goal (niet: Objective)

## Verificatie

```bash
npm run verify && npm run build   # verify = lint + typecheck + test
```

Worker job-status protocol (wanneer `DONE` / `SKIPPED` / `FAILED`): zie [docs/runbooks/worker-idempotency.md](./docs/runbooks/worker-idempotency.md).
