+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
+- Maximum 400 words total

+   - Create new todos with title, description, due date.
+   - Read/View all todos or a single todo by ID.
+   - Update existing todos (title, description, status).
+   - Delete completed or unnecessary todos.
+   - Filter todos by status (e.g., pending, completed).
+
+4. **DATA MODEL:**
+   - Todo
+     - id (integer, primary key)
+     - title (string)
+     - description (text)
+     - due_date (date)
+     - status (enum: 'pending', 'completed')
+
+5. **API ENDPOINTS:**
+   - GET /todos: Retrieve all todos.
+   - GET /todos/{id}: Retrieve a single todo by ID.
+   - POST /todos: Create a new todo.
+   - PUT /todos/{id}: Update an existing todo.
+   - DELETE /todos/{id}: Delete a todo.
+
+6. **CONSTRAINTS:**
+   - Must use SQLite as the database.
+   - No authentication required for accessing endpoints.

+PROJECT REQUIREMENTS (from product owner):
+1. **PROJECT NAME:** Todo-sovellus
+
+2. **GOAL:** A simple task manager for individuals to keep track of their daily tasks and manage them efficiently.
+
+3. **CORE FEATURES:**
+   - Create new todos with title, description, due date.
+   - Read/View all todos or a single todo by ID.
+   - Update existing todos (title, description, status).
+   - Delete completed or unnecessary todos.
+   - Filter todos by status (e.g., pending, completed).
+
+4. **DATA MODEL:**
+   - Todo
+     - id (integer, primary key)
+     - title (string)
+     - description (text)
+     - due_date (date)
+     - status (enum: 'pending', 'completed')
+
+5. **API ENDPOINTS:**
+   - GET /todos: Retrieve all todos.
+   - GET /todos/{id}: Retrieve a single todo by ID.
+   - POST /todos: Create a new todo.
+   - PUT /todos/{id}: Update an existing todo.
+   - DELETE /todos/{id}: Delete a todo.
+
+6. **CONSTRAINTS:**
+   - Must use SQLite as the database.
+   - No authentication required for accessing endpoints.
+   - Implement unit tests and integration tests to ensure functionality.
+
+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.

+2. NAMES: Pydantic schemas (UserCreate) must not shadow SQLAlchemy models (User)
+3. TYPES: All function parameters have type hints, return types specified

+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:
+- pytest as the test framework

+
+## Overview
+This project is a simple Todo application using FastAPI for the backend and SQLite as the database. It includes CRUD endpoints for managing tasks.
+
+## Files
+| File | Purpose |
+|------|---------|
+| models.py | Defines the data model for the todo items using SQLAlchemy ORM. |
+| schemas.py | Contains Pydantic schemas for validating request and response data. |
+| main.py | The FastAPI application, defining routes and business logic. |
+| pyproject.toml | Project metadata and dependencies. |
+| test_main.py | Unit tests for the FastAPI endpoints. |
+| Dockerfile | Docker configuration to build and run 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 | /todos/ | Create a new todo item. |
+| GET | /todos/ | List all todos or filter by status. |
+| GET | /todos/{id} | Retrieve a specific todo item by ID. |
+| PUT | /todos/{id} | Update an existing todo item. |
+| DELETE | /todos/{id} | Delete a todo item. |
+
+## Architecture
+The project follows a clean separation of concerns:
+- **models.py**: Defines the data model using SQLAlchemy ORM.
+- **schemas.py**: Contains Pydantic models for data validation and serialization.
+- **main.py**: Implements FastAPI routes, business logic, and database interactions.
+
+This logical structure makes it easy to understand and maintain each component independently.
+
+## Risk Assessment
+| Severity | Issue |
+|----------|-------|
+| LOW      | The project uses parameterized queries in the SQLAlchemy ORM which helps prevent SQL injection. However, input validation is minimal (e.g., no checks for `due_date` format). |
+| MEDIUM   | Error handling and database connection management are basic but adequate. Database connections are managed via context managers, which ensures proper closure of sessions. |
+| LOW      | The project uses consistent naming conventions for variables and functions, making the code easy to understand. However, there's room for improving documentation around API endpoints and models. |
+
+Overall assessment: "SHIP IT"
+```
