# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## Project Overview

A Kanban-based Project Management MVP. FastAPI backend serves a statically-exported Next.js frontend, all packaged in Docker. AI chat sidebar uses OpenRouter to manipulate the board.

## Architecture

- **Frontend** (`/frontend`): Next.js (static export) with React 19, TypeScript, Tailwind CSS 4, @dnd-kit for drag-and-drop
- **Backend** (`/backend`): Python FastAPI serving the static frontend at `/` and REST API at `/api/`
- **Database**: SQLite (`backend/kanban.db`) with `users` and `boards` tables; one board per user
- **AI**: OpenRouter API (`openai/gpt-oss-120b`) called from backend `/api/ai/kanban`
- **Auth**: Hardcoded `user` / `password` credentials; localStorage-based on frontend via `src/lib/auth.ts`

Data flow: Frontend (`src/lib/api.ts`) → FastAPI routes (`backend/main.py`) → SQLite (`backend/db.py`). Board state is a JSON blob stored in `boards.board_json`.

## Commands

### Frontend (`/frontend`)
```bash
npm run dev           # Dev server on port 3000
npm run build         # Static export to out/
npm run lint          # ESLint
npm run test:unit     # Vitest unit tests
npm run test:unit:watch
npm run test:e2e      # Playwright E2E tests
npm run test:all      # Unit + E2E
```

### Backend (`/backend`)
```bash
pytest test_api.py    # API tests
pytest test_db.py     # DB tests
```

### Full App (Docker)
```bash
docker-compose up     # Build and run on port 8000
docker-compose down
# Or use scripts/start-macos.sh / stop-macos.sh
```

## Coding Standards

- Keep it simple — no over-engineering, no unnecessary defensive programming, no extra features
- Use latest library versions with idiomatic approaches
- No emojis in any documentation or code
- When hitting issues, prove root cause with evidence before fixing

## Color Scheme

- Accent Yellow: `#ecad0a`
- Blue Primary: `#209dd7`
- Purple Secondary: `#753991`
- Dark Navy: `#032147`
- Gray Text: `#888888`

## Key Files

- `backend/main.py` — all API routes and AI integration
- `backend/db.py` — SQLite schema and queries
- `frontend/src/lib/kanban.ts` — board data types (`Card`, `Column`, `BoardData`) and `moveCard()`
- `frontend/src/lib/api.ts` — API client (`fetchKanban`, `saveKanban`, `askKanbanAI`)
- `frontend/src/components/KanbanBoard.tsx` — main board state management
- `docs/PLAN.md` — project plan; review before working on new features
- `.env` — `OPENROUTER_API_KEY` (project root, not committed to Docker image secrets)

Both servers are already running (port 8000 returns 200, port 3000 returns 200). Let me explore the app structure to understand the tabs before using Playwright to test them.
