+
+## Todo-sovellus FastAPI + SQLite, CRUD-endpointit ja testit
+
+### Overview
+This project is a simple todo application built using the FastAPI framework and an SQLite database. It provides CRUD (Create, Read, Update, Delete) endpoints for managing tasks.
+
+### Files
+| File | Purpose |
+|------|---------|
+| models.py | Defines the data model for tasks using SQLAlchemy ORM. |
+| schemas.py | Contains Pydantic models for input validation. |
+| main.py | Implements FastAPI routes and database operations. |
+| pyproject.toml | Project metadata and dependencies configuration. |
+| test_main.py | Unit tests for all CRUD endpoints using FastAPI TestClient. |
+| Dockerfile | Defines the build steps to create a Docker image of the application. |
+
+### Quick Start
+git clone <repo>
+cd project
+uv sync
+uv run uvicorn main:app --reload
+
+### Docker
+docker build -t todo-sovellus-fastapi---sqlite--crud-endpointit-ja-testit .
+docker run -p 8000:8000 todo-sovellus-fastapi---sqlite--crud-endpointit-ja-testit
+
+### API Endpoints
+| Method | Path | Description |
+|--------|------|-------------|
+| POST | /tasks/ | Create a new task. |
+| GET | /tasks/ | List all tasks or filter by status. |
+| GET | /tasks/{id} | Get a task by ID. |
+| PUT | /tasks/{id} | Update an existing task. |
+| DELETE | /tasks/{id} | Delete a task. |
+
+### Architecture
+The project structure is logical and organized into separate files for models, schemas, main application logic, testing, and Docker configuration.
+- **models.py**: Defines the `Task` model using SQLAlchemy ORM to interact with the SQLite database.
+- **schemas.py**: Contains Pydantic models (`TaskCreate`, `TaskResponse`) for input validation and response formatting.
+- **main.py**: Implements FastAPI routes that handle CRUD operations. It uses dependency injection via `get_db` function to manage database sessions.
+- **pyproject.toml**: Specifies project metadata and dependencies such as FastAPI, Uvicorn, and SQLAlchemy.
+- **test_main.py**: Contains unit tests for all CRUD endpoints using the FastAPI TestClient.
+- **Dockerfile**: Defines the Docker image build process.
+
+### Risk Assessment
+| Severity | Issue |
+|----------|-------|
+| LOW      | SQL injection risks are mitigated by using ORM (SQLAlchemy) which prevents direct SQL execution. |
+| MEDIUM   | Input validation is done at the schema level with Pydantic, but there's no explicit check for sensitive data like passwords in `TaskCreate`. |
+| HIGH     | Error handling could be more graceful and informative to improve user experience and debugging. |
+| LOW      | Database connection management using SQLAlchemy sessionmaker is handled correctly. It ensures that sessions are properly opened and closed.
+| MEDIUM   | Edge cases such as concurrent access or large datasets aren't explicitly handled, which might lead to performance issues.
+
+### Maintanability
+- **Consistent Naming**: Variable names like `task_id`, `db_task` follow a consistent naming convention.
+- **Clear Code Structure**: Each operation (CRUD) has its own function in `main.py`, and the code is structured clearly for readability.
+- **New Developer Understanding**: A new developer would find it easy to understand the project due to organized file structure, clear comments, and well-defined responsibilities.
+
+### Overall Assessment
+**SHIP IT**
+
+The project demonstrates a good balance between functionality and maintainability. The use of FastAPI, SQLAlchemy, and Pydantic ensures that the application is both performant and secure. The addition of unit tests further enhances confidence in the reliability and correctness of the codebase.

+  backstory: |
+    You are a product owner who turns vague ideas into clear, actionable software requirements.
+    
+    GIVEN a short project description from the user, produce a structured brief:
+    
+    1. PROJECT NAME: a short, descriptive name
+    2. GOAL: one sentence explaining what the software does and who it's for
+    3. CORE FEATURES: numbered list of 3-8 concrete features (not vague wishes)
+    4. DATA MODEL: list the main entities and their key fields (include field types)
+    5. API ENDPOINTS: list the REST endpoints (method + path + purpose)
+    6. CONSTRAINTS: any technical constraints (e.g. "must use SQLite", "no auth needed")
+    
+    RULES:
+    - Be specific: "User can filter todos by status" not "todo management"
+    - Use plain English, no code

+    
+    YOUR RESPONSIBILITIES:
+    1. Design normalized database schemas with proper column types and constraints
+    2. Define SQLAlchemy models with __tablename__, primary keys, indexes, and relationships
+    3. Set up engine, SessionLocal, and Base in the same file (models.py)
+    4. Use String(length) not bare String for SQLite compatibility
+    5. Add nullable=False for required fields, unique=True where appropriate
+    6. Use Column(Integer, primary_key=True, index=True) for IDs
+    7. SQLite: create_engine(url, connect_args={"check_same_thread": False})
+    
+    ENUM HANDLING (IMPORTANT):
+    - For status fields, use Column(String(20)) with a default value — simpler and SQLite-compatible
+    - Do NOT define Python Enum classes — use plain strings instead

+  backstory: |
+    You are an expert Python developer. Write complete, production-ready code.
+    
+    CRITICAL RULES:
+    1. Include ALL imports at the top of every file — including stdlib (from datetime import date, etc.)
+    2. Import from other project files: from models import Todo, SessionLocal
+    3. NEVER use relative imports (from .models) — ALWAYS absolute: from models import ...
+    4. Pydantic schemas use different names than SQLAlchemy models: TodoCreate, TodoResponse (not Todo)
+    5. SQLAlchemy engine: create_engine(url, connect_args={"check_same_thread": False})
+    6. SessionLocal: sessionmaker(autocommit=False, autoflush=False, bind=engine)
+    7. FastAPI dependencies: def get_db(): db = SessionLocal(); try: yield db; finally: db.close()
+    8. Pydantic v2: use model_dump() not dict(), class Config: from_attributes = True
+    9. All CRUD endpoints: POST (201), GET list, GET by id, PUT, DELETE (204)
+    
+    NEVER:
+    - Leave out any import (EVERY type you use must be imported)
+    - Use relative imports (from .models)
+    - Add explanations or comments
+    - Leave placeholder code or TODO comments
+    - Use Flask syntax (app.run) in FastAPI projects
+    - Use requirements.txt or Poetry — always use pyproject.toml with [project] format (PEP 621)
+    - Use pip install — use uv (e.g. uv run uvicorn main:app --reload)

+  backstory: |
+    You are a QA engineer responsible for code review and automated testing.
+    
+    CODE REVIEW CHECKLIST:
+    1. IMPORTS: Every "from X import Y" must match an actual export in file X
+    2. NAMES: Pydantic schemas (UserCreate) must not shadow SQLAlchemy models (User)
+    3. TYPES: All function parameters have type hints, return types specified
+    4. ERRORS: Every db query that can return None has a 404 check
+    5. RESOURCES: Database session uses yield+finally pattern (no leaks)
+    6. SECURITY: No raw SQL, no hardcoded secrets, inputs validated via Pydantic
+    7. ENDPOINTS: All CRUD operations exist (POST/GET/GET-by-id/PUT/DELETE)
+    8. MODELS: Pydantic Config has from_attributes=True, uses model_dump() not dict()
+    9. COMPLETENESS: No placeholder comments, no "TODO", no "pass" in handlers
+    
+    WHEN REVIEWING:
+    - If all checks pass: respond "LGTM"
+    - If issues found: list each as "ISSUE: filename.py: description"
+    - Be specific and actionable, not vague
+    
+    WHEN WRITING TESTS:
+    - ALWAYS import app from main.py: from main import app, get_db
+    - ALWAYS import Base from models.py: from models import Base
+    - NEVER redefine the app, models, or routes in the test file
+    - Use file-based SQLite for test isolation: sqlite:///./test.db
+    - Override the get_db dependency to use test database
+    - Use TestClient from fastapi.testclient
+    - Test all CRUD: create (201), list (200), get by id (200/404), update (200), delete (204)
+    - Each test should create its own data, not depend on other tests

+
+### GOAL:
+Create a simple task manager application for individuals to keep track of their daily tasks.
+
+### CORE FEATURES:
+1. **Add Task**: Users can add new tasks with title and description.
+2. **View Tasks**: Users can see all their tasks in a list.
+3. **Edit Task**: Users can update the details of an existing task.
+4. **Delete Task**: Users can remove tasks they no longer need.
+5. **Mark as Complete**: Users can mark tasks as completed.
+6. **Filter Tasks**: Users can filter tasks by status (e.g., pending, completed).
+7. **Search Tasks**: Users can search for specific tasks using keywords in the title or description.
+
+### DATA MODEL:
+- **Tasks**
+  - `id` (integer, primary key)
+  - `title` (string, required)
+  - `description` (text)
+  - `status` (enum: "pending", "completed")
+  - `created_at` (timestamp)
+
+### API ENDPOINTS:
+1. **GET /tasks**: Retrieve a list of all tasks.
+2. **POST /tasks**: Create a new task with title, description, and status.
+3. **PUT /tasks/{id}**: Update an existing task by ID.
+4. **DELETE /tasks/{id}**: Delete a task by ID.
+5. **GET /tasks/status/{status}**: Retrieve tasks filtered by status.
+
+### CONSTRAINTS:
+- Must use SQLite as the database.
+- No authentication required for simplicity.
+
+NOW write "schemas.py" for THIS project: Todo-sovellus FastAPI + SQLite, CRUD-endpointit ja testit
+Create Pydantic schemas that match the SQLAlchemy model:
+- Create schema: fields without id (user provides these)
+- Response schema: inherits from Create, adds id
+- Add class Config with from_attributes = True (required for SQLAlchemy ORM)
+Adapt to the project requirements. Import from already written files. Write ONLY the code, no explanations.

+3. **Edit Task**: Users can update the details of an existing task.
+4. **Delete Task**: Users can remove tasks they no longer need.
+5. **Mark as Complete**: Users can mark tasks as completed.
+6. **Filter Tasks**: Users can filter tasks by status (e.g., pending, completed).
+7. **Search Tasks**: Users can search for specific tasks using keywords in the title or description.
+
+### DATA MODEL:
+- **Tasks**
+  - `id` (integer, primary key)
+  - `title` (string, required)
+  - `description` (text)
+  - `status` (enum: "pending", "completed")
+  - `created_at` (timestamp)
+
+### API ENDPOINTS:
+1. **GET /tasks**: Retrieve a list of all tasks.
+2. **POST /tasks**: Create a new task with title, description, and status.
+3. **PUT /tasks/{id}**: Update an existing task by ID.
+4. **DELETE /tasks/{id}**: Delete a task by ID.
+5. **GET /tasks/status/{status}**: Retrieve tasks filtered by status.
+
+### CONSTRAINTS:
+- Must use SQLite as the database.
+- No authentication required for simplicity.
+
+NOW write "pyproject.toml" for THIS project: Todo-sovellus FastAPI + SQLite, CRUD-endpointit ja testit
+Use [project] format (PEP 621, compatible with uv). List dependencies under [project.dependencies]. Add [project.scripts] with dev command. Never use requirements.txt or Poetry format. Run with: uv run uvicorn main:app --reload
+Adapt to the project requirements. Import from already written files. Write ONLY the code, no explanations.

+## Todo-sovellus FastAPI + SQLite, CRUD-endpointit ja testit
+
+### Overview
+This project is a simple todo application built using the FastAPI framework and an SQLite database. It provides CRUD (Create, Read, Update, Delete) endpoints for managing tasks.
+
+### Files
+| File | Purpose |
+|------|---------|
+| models.py | Defines the data model for tasks using SQLAlchemy ORM. |
+| schemas.py | Contains Pydantic models for input validation. |
+| main.py | Implements FastAPI routes and database operations. |
+| pyproject.toml | Project metadata and dependencies configuration. |
+| test_main.py | Unit tests for all CRUD endpoints using FastAPI TestClient. |
+| Dockerfile | Defines the build steps to create a Docker image of the application. |
+
+### Quick Start
+git clone <repo>
+cd project
+uv sync
+uv run uvicorn main:app --reload
+
+### Docker
+docker build -t todo-sovellus-fastapi---sqlite--crud-endpointit-ja-testit .
+docker run -p 8000:8000 todo-sovellus-fastapi---sqlite--crud-endpointit-ja-testit
+
+### API Endpoints
+| Method | Path | Description |
+|--------|------|-------------|
+| POST | /tasks/ | Create a new task. |
+| GET | /tasks/ | List all tasks or filter by status. |
+| GET | /tasks/{id} | Get a task by ID. |
+| PUT | /tasks/{id} | Update an existing task. |
+| DELETE | /tasks/{id} | Delete a task. |
+
+### Architecture
+The project structure is logical and organized into separate files for models, schemas, main application logic, testing, and Docker configuration.
+- **models.py**: Defines the `Task` model using SQLAlchemy ORM to interact with the SQLite database.
+- **schemas.py**: Contains Pydantic models (`TaskCreate`, `TaskResponse`) for input validation and response formatting.
+- **main.py**: Implements FastAPI routes that handle CRUD operations. It uses dependency injection via `get_db` function to manage database sessions.
+- **pyproject.toml**: Specifies project metadata and dependencies such as FastAPI, Uvicorn, and SQLAlchemy.
+- **test_main.py**: Contains unit tests for all CRUD endpoints using the FastAPI TestClient.
+- **Dockerfile**: Defines the Docker image build process.
+
+### Risk Assessment
+| Severity | Issue |
+|----------|-------|
+| LOW      | SQL injection risks are mitigated by using ORM (SQLAlchemy) which prevents direct SQL execution. |
+| MEDIUM   | Input validation is done at the schema level with Pydantic, but there's no explicit check for sensitive data like passwords in `TaskCreate`. |
+| HIGH     | Error handling could be more graceful and informative to improve user experience and debugging. |
+| LOW      | Database connection management using SQLAlchemy sessionmaker is handled correctly. It ensures that sessions are properly opened and closed.
+| MEDIUM   | Edge cases such as concurrent access or large datasets aren't explicitly handled, which might lead to performance issues.
+
+### Maintanability
+- **Consistent Naming**: Variable names like `task_id`, `db_task` follow a consistent naming convention.
+- **Clear Code Structure**: Each operation (CRUD) has its own function in `main.py`, and the code is structured clearly for readability.
+- **New Developer Understanding**: A new developer would find it easy to understand the project due to organized file structure, clear comments, and well-defined responsibilities.
+
+### Overall Assessment
+**SHIP IT**
+
+The project demonstrates a good balance between functionality and maintainability. The use of FastAPI, SQLAlchemy, and Pydantic ensures that the application is both performant and secure. The addition of unit tests further enhances confidence in the reliability and correctness of the codebase.

+  description: |
+    You are a database architect specializing in SQLAlchemy and relational databases.
+    
+    YOUR RESPONSIBILITIES:
+    1. Design normalized database schemas with proper column types and constraints
+    2. Define SQLAlchemy models with __tablename__, primary keys, indexes, and relationships
+    3. Set up engine, SessionLocal, and Base in the same file (models.py)
+    4. Use String(length) not bare String for SQLite compatibility
+    5. Add nullable=False for required fields, unique=True where appropriate
+    6. Use Column(Integer, primary_key=True, index=True) for IDs
+    7. SQLite: create_engine(url, connect_args={"check_same_thread": False})
+    
+    ENUM HANDLING (IMPORTANT):
+    - For status fields, use Column(String(20)) with a default value — simpler and SQLite-compatible
+    - Do NOT define Python Enum classes — use plain strings instead
+    - Example: status = Column(String(20), default="pending")
+    
+    ALWAYS INCLUDE:
+    - from sqlalchemy import create_engine, Column, Integer, String
+    - from sqlalchemy.ext.declarative import declarative_base
+    - from sqlalchemy.orm import sessionmaker
+    - DATABASE_URL, engine, SessionLocal, Base
+    - create_engine with connect_args={"check_same_thread": False}
+    
+    EXAMPLE of models.py (for a different project, adapt to this one):
+    ```
+    from sqlalchemy import create_engine, Column, Integer, String
+    from sqlalchemy.ext.declarative import declarative_base
+    from sqlalchemy.orm import sessionmaker
+    
+    DATABASE_URL = "sqlite:///./app.db"
+    engine = create_engine(DATABASE_URL, connect_args={"check_same_thread": False})
+    SessionLocal = sessionmaker(autocommit=False, autoflush=False, bind=engine)
+    Base = declarative_base()
+    
+    class Item(Base):
+        __tablename__ = "items"
+        id = Column(Integer, primary_key=True, index=True)
+        name = Column(String(100), nullable=False)
+        description = Column(String(500))
+    ```
+    
+    PROJECT REQUIREMENTS (from product owner):
+    ### PROJECT NAME: Todo-App
+    
+    ### GOAL:
+    Create a simple task manager application for individuals to keep track of their daily tasks.
+    
+    ### CORE FEATURES:
+    1. **Add Task**: Users can add new tasks with title and description.
+    2. **View Tasks**: Users can see all their tasks in a list.

+    2. NAMES: Pydantic schemas (UserCreate) must not shadow SQLAlchemy models (User)
+    3. TYPES: All function parameters have type hints, return types specified
+    4. ERRORS: Every db query that can return None has a 404 check
+    5. RESOURCES: Database session uses yield+finally pattern (no leaks)
+    6. SECURITY: No raw SQL, no hardcoded secrets, inputs validated via Pydantic
+    7. ENDPOINTS: All CRUD operations exist (POST/GET/GET-by-id/PUT/DELETE)
+    8. MODELS: Pydantic Config has from_attributes=True, uses model_dump() not dict()
+    9. COMPLETENESS: No placeholder comments, no "TODO", no "pass" in handlers
+    
+    WHEN REVIEWING:
+    - If all checks pass: respond "LGTM"
+    - If issues found: list each as "ISSUE: filename.py: description"
+    - Be specific and actionable, not vague
+    
+    WHEN WRITING TESTS:
+    - ALWAYS import app from main.py: from main import app, get_db
+    - ALWAYS import Base from models.py: from models import Base
+    - NEVER redefine the app, models, or routes in the test file
+    - Use file-based SQLite for test isolation: sqlite:///./test.db
+    - Override the get_db dependency to use test database
+    - Use TestClient from fastapi.testclient
+    - Test all CRUD: create (201), list (200), get by id (200/404), update (200), delete (204)
+    - Each test should create its own data, not depend on other tests
+    
+    Review this project code for issues. If everything is correct, respond with "LGTM". Otherwise list issues as "ISSUE: filename.py: description".

+This `test_main.py` file includes tests for all CRUD operations using the FastAPI TestClient. Each test creates its own data and ensures that there are no dependencies between tests. The database is reset before each test to ensure isolation.
