Read 5 files 既存フロントエンドの全体像を把握しました。成果物の作成に進みます。まず作業を追跡するためタスクを登録し、frontend/AGENTS.md を作成します。 ● Write(AGENTS.md) Wrote 110 lines to AGENTS.md # Frontend The existing frontend is a pure client-side Kanban demo ("Kanban Studio"). It has no backend calls and holds all state in memory, resetting on reload. Later plan parts wire it to the FastAPI backend, add auth, and add an AI chat sidebar. ## Stack - Next.js 16 (App Router) with React 19 - TypeScript … +100 lines Now the main deliverable: enriching docs/PLAN.md. I'll rewrite it with detailed checklists, tests, and success criteria per part while preserving the confirmed decisions. ● Write(D:\temp\pm\docs\PLAN.md) Added 267 lin criteria. Work proceeds one part at a time; each part must meet its success criteria before the next begins. Enrich this document to plan out each of these parts in detail, with substeps listed out as a checklis t to be checked off by the agent, and with tests and success critieria for each. Also create an AGENTS .md file inside the frontend directory that describes the existing code there. Ensure the user checks and approves the plan. ## Confirmed decisions Part 2: Scaffolding - Frontend serving: Next.js static export (`output: 'export'`), served by FastAPI `StaticFiles` at `/`. Single Docker container. No SSR. - Auth: hardcoded `user` / `password`; on success the server issues a session stored in an HttpOnly cookie. Logout clears it. Multiple users supported in the schema for the future. - Database: SQLite. `users` table plus a `boards` table storing the whole board as a JSON blob in one column (`BoardData` shape). Created automatically if it does not exist. - AI: OpenRouter, model `openai/gpt-oss-120b`, `OPENROUTER_API_KEY` from root `.env`. - Package manager for Python (in Docker): `uv`. Set up the Docker infrastructure, the backend in backend/ with FastAPI, and write the start and stop s cripts in the scripts/ directory. This should serve example static HTML to confirm that a 'hello world ' example works running locally and also make an API call. ## Conventions Part 3: Add in Frontend - Backend package: `backend/app/` (FastAPI app), tests in `backend/tests/`. - Run backend tests with `uv run pytest`. Run frontend unit tests with `npm run test:unit` and e2e with `npm run test:e2e`. - Keep it simple: no features beyond what each part requires, no speculative abstraction. - No emojis anywhere. Keep docs minimal. Now update so that the frontend is statically built and served, so that the app has the demo Kanban bo ard displayed at /. Comprehensive unit and integration tests. --- Part 4: Add in a fake user sign in experience ## Part 1: Plan (this document) Now update so that on first hitting /, you need to log in with dummy credentials ("user", "password") in order to see the Kanban, and you can log out. Comprehensive tests. - [x] Enrich this document with per-part checklists, tests, and success criteria. - [x] Create `frontend/AGENTS.md` describing the existing frontend code. - [ ] User reviews and approves the plan. Part 5: Database modeling Tests / verification: - The user confirms the plan and the confirmed decisions above. Now propose a database schema for the Kanban, saving it as JSON. Document the database approach in doc s/ and get user sign off. Success criteria: - This document and `frontend/AGENTS.md` exist and are approved by the user. Part 6: Backend --- Now add API routes to allow the backend to read and change the Kanban for a given user; test this thor oughly with backend unit tests. The database should be created if it doesn't exist. ## Part 2: Scaffolding (Docker + FastAPI + scripts) Part 7: Frontend + Backend Goal: a running container that serves a placeholder static page at `/` and exposes a working API endpoint. No frontend build yet. Now have the frontend actually use the backend API, so that the app is a proper persistent Kanban boar d. Test very throughly. - [ ] Create `backend/pyproject.toml` (managed by `uv`) with FastAPI and Uvicorn. - [ ] Create `backend/app/main.py` with a FastAPI app: - [ ] - [ ] Write `backend/AGENTS.md` describing the backend layout and how to run it. - [ ] Create `Dockerfile` (root) that uses `uv` to install deps and runs Uvicorn. - [ ] Create `.dockerignore`. - [ ] Write start/stop scripts in `scripts/`: - [ ] `start.sh` / `stop.sh` (Mac + Linux) - [ ] `start.ps1` / `stop.ps1` (Windows) - [ ] Scripts build/run and stop the Docker container, mapping a port and passing `.env`. - [ ] Add `backend/tests/test_health.py` using FastAPI `TestClient`. Part 8: AI connectivity Tests: - `uv run pytest` passes (`GET /api/health` returns 200 and expected JSON). - Container builds and runs; `curl http://localhost:8000/api/health` returns ok. - Visiting `/` in a browser shows the hello-world page and the health result. Now allow the backend to make an AI call via OpenRouter. Test connectivity with a simple "2+2" test an d ensure the AI call is working. Success criteria: - One command (the start script) builds and runs the container. - `/` serves placeholder HTML and the page successfully makes an API call. - Stop script cleanly stops the container. Part 9: Now extend the backend call so that it always calls the AI with the JSON of the Kanban board, plus the user's question (and conversation history). The AI should respond with Structured Outputs tha t includes the response to the user and optionaly an update to the Kanban. Test thoroughly. --- Part 10: Now add a beautiful sidebar widget to the UI supporting full AI chat, and allowing the LLM (a s it determines) to update the Kanban based on its Structured Outputs. If the AI updates the Kanban, t hen the UI should refresh automatically. No newline at end of file ## Part 3: Add in Frontend (static build served by backend) Goal: the real demo Kanban board is served at `/` from the container. - [ ] Set `output: 'export'` in `frontend/next.config.ts` (and any config needed for static export, e.g. image handling if applicable). - [ ] Confirm the app builds statically (`npm run build` produces `out/`). - [ ] Update the Docker build to build the frontend and copy `frontend/out/` into the static directory the backend serves (multi-stage: Node build stage, then Python runtime stage). - [ ] Remove the placeholder `index.html` (now replaced by the exported app). - [ ] Ensure client-side routing / assets resolve correctly under `/`. - [ ] Keep existing frontend unit tests passing; keep Playwright e2e for the demo board. Tests: - Frontend unit tests pass: `npm run test:unit`. - Frontend e2e pass against the dev server: `npm run test:e2e`. - Integ Success criteria: - The container serves the real Kanban demo at `/` (not the placeholder). - All existing frontend tests pass; the board is fully interactive in the container. --- ## Part 4: Fake user sign in Goal: `/` requires login (`user` / `password`); logged-in users see the Kanban; logout returns to the login screen. Session via HttpOnly cookie. - [ ] Backend auth routes: - [ ] `POST /api/login` validates hardcoded credentials; on success sets an HttpOnly session cookie and returns the user; on failure returns 401. - [ ] `POST /api/logout` clears the session cookie. - [ ] `GET /api/me` returns the current user or 401 if not authenticated. - [ ] Session mechanism: signed cookie or server-side session id (keep simple). - [ ] Frontend: - [ ] Add a login screen (uses the color scheme; purple submit button). - [ ] On load, call `GET /api/me`; show login if unauthenticated, board if authenticated. - [ ] Add a logout control that calls `POST /api/logout` and returns to login. - [ ] Show an error message on invalid credentials. - [ ] Handle unauthenticated API access consistently (401 -> show login). Tests: - Backend unit tests: login success sets cookie; login failure returns 401; `me` reflects auth state; logout clears session. - Frontend unit tests for the login form (submit, error state, success transition). - E2E: visiting `/` shows login; wrong credentials show error; correct credentials show the board; logout returns to login; reload keeps session until logout. Success criteria: - Cannot see the board without logging in; login/logout works; session persists across reloads via the cookie. --- ## Part 5: Database modeling Goal: a documented SQLite schema storing the Kanban as JSON, signed off by the user. - [ ] Write `docs/DATABASE.md` describing: - [ ] `users` table (id, username, unique constraint; password handling note for MVP). - [ ] `boards` table (id, user_id FK, `data` JSON column holding `BoardData`, timestamps). - [ ] Relationship: one board per user for the MVP; schema allows multiple. - [ ] The JSON shape (mirrors frontend `BoardData`: columns + cards map). - [ ] How the DB is created on first run if missing; seed strategy (seed `initialData` for a new user's board). - [ ] Note migration/versioning approach (kept minimal for MVP). - [ ] User reviews and signs off on the schema. Tests / verification: - Schema doc reviewed against frontend `BoardData` for consistency. - User approves `docs/DATABASE.md`. Success criteria: - `docs/DATABASE.md` exists, is consistent with the frontend model, and is approved. --- ## Part 6: Backend (Kanban API + persistence) Goal: authenticated API to read and update a user's board, backed by SQLite, DB auto-created if missing. - [ ] Add SQLite access (stdlib `sqlite3` or SQLModel/SQLAlchemy - pick the simplest that fits; store `data` as JSON text). - [ ] On startup, create the DB and tables if they do not exist. - [ ] Implement routes (all require auth): - [ ] `GET /api/board` returns the current user's board (creating a seeded board if the user has none). - [ ] `PUT /api/board` replaces the current user's board with the posted `BoardData` (validated). - [ ] V - [ ] Seed a new user's board with the demo `initialData` equivalent. Tests (backend unit/integration, thorough): - DB and tables auto-create when the file is absent. - `GET /api/board` returns a seeded board for a fresh user. - `PUT /api/board` persists changes; a subsequent `GET` returns them. - Unauthenticated requests to board routes return 401. - Invalid payloads return 422. - Persistence survives process restart (data written to the SQLite file). Success criteria: - Board can be read and updated per user via the API, persisted in SQLite, with the DB created automatically. Backend tests pass. --- ## Part 7: Frontend + Backend integration - [ ] Choose an update strategy (save on each change; keep it simple and correct). - [ ] Handle loading and error states minimally. - [ ] Keep the `BoardData` type as the shared contract; ensure the frontend sends the same shape the backend validates. - [ ] Ensure static-export build still works with these client-side fetches (same origin). Tests (thorough): - Frontend unit tests for the data layer (fetch board, save board) with mocked API. - E2E against the running container: log in, modify the board (add/move/rename/delete), reload, and confirm changes persisted; log out and back in and confirm persistence. Success criteria: - The board is a real persistent Kanban: all edits survive reloads and re-logins. Unit and e2e tests pass. --- ## Part 8: AI connectivity Goal: the backend can call OpenRouter and a simple sanity test works. - [ ] Add an OpenRouter client in the backend using `OPENROUTER_API_KEY` and model `openai/gpt-oss-120b`. - [ ] Add a minimal internal test/endpoint that asks the model "what is 2+2" and checks the response contains 4. - [ ] Fail clearly if the API key is missing. Tests: - Connectivity test: the "2+2" call returns a response containing 4 (network-dependent; guard/skip when no key is present in CI). - Unit test for the client with a mocked HTTP response. Success criteria: - The backend can successfully call the model and the 2+2 sanity check passes. --- ## Part 9: AI over the Kanban with Structured Outputs Goal: the backend sends the board JSON plus the user's question and history to the model, and receives a structured response (a reply plus an optional board update). - [ ] Define the structured output schema: `{ reply: string, board_update?: BoardData }` (or a well-defined patch). Use OpenRouter Structured Outputs. - [ ] Add `POST /api/chat` (authenticated): accepts the user message and conversation history; loads the current board; calls the model; returns the structured result. - [ ] If `board_update` is present, validate it and persist it (reusing Part 6 logic). - [ ] Keep conversation history handling simple (client sends history, or store per user). - [ ] Robustly handle model output that omits a board update (reply only). Tests (thorough): - Unit tests with mocked model responses: reply-only; reply-with-valid-update (persisted); invalid update rejected without corrupting the stored board. - Integration: a message like "add a card X to Backlog" yields a board update that, when persisted, contains the new card. - Auth required; invalid input returns 422. Success criteria: - `POST /api/chat` returns a structured reply and can update the persisted board correctly and safely. Tests pass. --- ## Part 10: AI chat sidebar UI Goal: a polished chat sidebar; the AI can update the board and the UI refreshes automatically when it does. - [ ] Add a sidebar chat widget matching the color scheme (blue/purple/yellow accents). - [ ] Message list (user + assistant), input, send button, loading state. - [ ] Sensible empty state and error handling. - [ ] Wire it to `POST /api/chat`, sending the message and history. - [ ] W Tests (thorough): - Frontend unit tests: rendering messages, sending a message (mocked API), showing the reply, and triggering a board refresh when an update is returned. - E2E against the container: open the sidebar, ask the AI to add/move a card, confirm the assistant reply appears and the board updates automatically without manual reload. Success criteria: - A working, attractive AI chat sidebar where the assistant can create/edit/move cards and the board refreshes automatically when it does. Unit and e2e tests pass. --- ## Overall done criteria - Single Docker container: log in, see and edit a persistent Kanban board, and use an AI chat sidebar that can modify the board. Start/stop scripts for Mac, Windows, and Linux. All parts' tests pass. Part 1 の成果物を作成しました。 完了した成果物 1. frontend/AGENTS.md(新規作成) 既存フロントエンドの説明書。スタック(Next.js 16 / React 19 / Tailwind v4 / dnd-kit)、ディレクトリ構成、データモデル(Card / Column / BoardData、カードは id マップで保持)、状態管理(KanbanBoard が唯一のステートフルコンポーネント、全てメモリ内・永続化なし)、スタイル(CSS 変数のカラースキーム)、コマンド、そして後続パートへの注記(静的エクスポート可能・BoardData が永続化形状として自然)を記載。 2. docs/PLAN.md(詳細化) 確定した4つの設計判断を冒頭に明記し、Part 2〜10 それぞれに以下を付与: - - [ ] 形式の実装サブステップ・チェックリスト - テスト(単体 / 統合 / E2E の区別) - 成功基準(Done の定義) 主な流れ: - Part 2: Docker + FastAPI 骨組み、/api/health、hello world 静的配信、start/stop スクリプト(Mac/Win/Linux) - Part 3: Next 静的エクスポートを multi-stage ビルドで backend 配信 - Part 4: HttpOnly Cookie セッション認証(login/logout/me) - Part 5: docs/DATABASE.md(users + boards の JSON blob スキーマ)— ユーザー承認ポイント - Part 6: 認証付き board API + SQLite 永続化(DB 自動生成) - Part 7: フロント⇔バックエンド結合で永続化 - Part 8: OpenRouter 接続(2+2 サニティチェック) - Part 9: 盤面 JSON + 履歴を投げて Structured Outputs で応答+盤面更新 - Part 10: チャットサイドバー UI と盤面自動リフレッシュ 確認のお願い PLAN.md 内にユーザー承認ポイントを2箇所組み込みました: - Part 1(本計画そのもの)の承認 - Part 5(DBスキーマ)の承認 この計画内容でよろしいか、ご確認ください。修正・追加のご希望があれば反映します。承認いただければ、Part 2(スキャフォールディング)に進みます。 一点、判断が必要になりそうな点を先出しでお伝えします(今すぐ決める必要はありません): Part 6 の SQLite アクセス方法を「標準ライブラリ sqlite3」と「SQLModel/SQLAlchemy」のどちらにするか。MVP の単純さ優先なら前者を推奨しますが、Part 6 着手時に改めて確認します。 ✻ Cooked for 2m 29s ※ recap: Building a Kanban PM app in Docker; I just finished Part 1, creating frontend/AGENTS.md and detailing docs/PLAN.md with per-part checklists, tests, and success criteria. Next: get your approval on the plan, then start Part 2 scaffolding.
