Usage Guide

Step 1: Load Inputs

Load all required inputs for PRP generation:

Required Inputs:

1. Analysis Document: /docs/implementation/analysis/feature-{issue-number}-analysis.md

   • Requirements (functional and non-functional)
   • Security considerations
   • Technical stack requirements
   • Dependencies
   • Scope definition
   • Identified risks

   • Library integration strategies
   • Dependency resolution
   • Implementation path
   • Design decisions
   • Identified issues/gaps

Loading Pattern:

# Read analysis document
analysis = read_document("/docs/implementation/analysis/feature-{issue-number}-analysis.md")

# Parse synthesized design (from synthesis step)
design = parse_synthesized_design()

# Extract key information
requirements = extract_requirements(analysis)
architecture = extract_architecture(design)
libraries = extract_libraries(design)
dependencies = extract_dependencies(design)
implementation_plan = extract_implementation_plan(design)

Step 2: Create PRP Header

Use prp-template.md header section:

# Product Requirements Prompt: [Feature Name] (Issue #{issue-number})

**Date**: [YYYY-MM-DD]
**Designer**: Design Orchestrator (Claude Code)
**Issue**: #{issue-number} - [Issue Title]
**Analysis Document**: /docs/implementation/analysis/feature-{issue-number}-analysis.md

---

**Status**: Ready for Implementation (Phase 3)
**Complexity**: [Low / Medium / High]
**Estimated Effort**: [Hours/Days]
**Priority**: [P0 / P1 / P2 / P3]

---

Complexity Guidelines:

• Low: Single component, <3 files, well-documented libraries
• Medium: Multiple components, 3-10 files, some custom logic
• High: Complex architecture, >10 files, custom integrations

Step 3: Write Executive Summary

Provide 2-3 paragraph overview of the design:

Executive Summary Template:

## Executive Summary

This document provides comprehensive implementation guidance for [feature name],
which [high-level description of what feature does and why it's valuable].

**Architectural Approach**: [Brief description of architecture - e.g., "Service layer
pattern with FastAPI endpoints, SQLAlchemy ORM, and Redis caching"]

**Key Libraries**: [List 3-5 primary libraries - e.g., "FastAPI 0.95.0 for API
framework, SQLAlchemy 2.0.0 for ORM, PassLib 1.7.4 for password hashing"]

**Implementation Strategy**: [Brief description of implementation phases - e.g.,
"4-phase approach: (1) Data models and repository, (2) Service layer business logic,
(3) API endpoints, (4) Testing and validation"]

**Key Considerations**: [1-2 important considerations - e.g., "Security-first
approach with OWASP compliance, performance target of <200ms API response time"]

Example:

## Executive Summary

This document provides comprehensive implementation guidance for user authentication
system, which enables secure user login, session management, and access control for
the application.

**Architectural Approach**: Service layer pattern with FastAPI RESTful API endpoints,
SQLAlchemy ORM for user persistence, PassLib for secure password hashing, and JWT
tokens for session management.

**Key Libraries**: FastAPI 0.95.0 (API framework), SQLAlchemy 2.0.0 (ORM), PassLib
1.7.4 (password hashing), python-jose 3.3.0 (JWT tokens), pydantic 1.10.7 (validation).

**Implementation Strategy**: 4-phase approach: (1) User data model and repository
with SQLAlchemy, (2) Authentication service with PassLib and JWT, (3) FastAPI
endpoints with pydantic validation, (4) Comprehensive testing with pytest and mocks.

**Key Considerations**: OWASP Top 10 compliance for authentication vulnerabilities,
bcrypt with cost factor 12 for password hashing, rate limiting for brute force
protection, secure session token management with expiration.

Step 4: Document Requirements Reference

Link to analysis document and summarize key requirements:

Requirements Reference Template:

## Requirements Reference

**Source**: [Link to analysis document]

### Functional Requirements (Summary)

Purpose: [What this model represents] Fields:

from pydantic import BaseModel, Field
from [library] import [ValidationMixin]

class [ModelName](BaseModel):
    field1: type = Field(..., description="...")  # Validation
    field2: type = Field(default=..., ge=..., le=...)  # Range validation
    # ... more fields

5. PassLib.verify() checks password hash
6. JWT token generated (python-jose)
7. Token returned to client

Error Handling Strategy

Library Exception Mapping:

Library Exception	Architectural Exception	HTTP Status	User Message
[LibraryException]	[AppException]	[Code]	[Message]

Error Handling Pattern:

try:
    # Library operation
except LibraryException as e:
    # Map to architectural exception

### Installation Commands

**Install all dependencies**:
```bash
# Install using pip
pip install -r requirements.txt

# Or using uv (faster)

Testing Strategy Template:

## Testing Strategy

### Overview

Comprehensive testing approach with [X]% code coverage target, including unit tests
(with mocks), integration tests (with test containers), and end-to-end tests (full
API flow).

### Unit Testing

**Scope**: Individual functions, classes, methods in isolation

**Framework**: pytest

**Coverage Target**: [X]% for all modules

**Mocking Strategy**:
- Mock [Library1] using unittest.mock
- Mock [Library2] using [library-specific test fixtures]
- Mock database using SQLAlchemy in-memory database

**Test Structure**:

tests/ ├── unit/ │ ├── test_models.py # Data model validation tests │ ├── test_repositories.py # Repository logic tests (mocked DB) │ ├── test_services.py # Service logic tests (mocked deps) │ └── test_validators.py # Custom validator tests

**Example Unit Test**:
```python
# Test with mocked library
from unittest.mock import Mock
import pytest

def test_service_method():
    # Mock library dependency
    mock_lib = Mock()
    mock_lib.method.return_value = "expected"

    # Test service with mock
    service = MyService(mock_lib)
    result = service.do_something()

    assert result == "processed_expected"
    mock_lib.method.assert_called_once()

Key Test Cases:

• [Component1]: Test [key functionality]
• [Component2]: Test [error handling]
• [Model1]: Test [validation rules]

Integration Testing

Scope: Components working together with real library instances

Framework: pytest with testcontainers

Test Containers Used:

• PostgreSQL: testcontainers.postgres.PostgresContainer
• Redis: testcontainers.redis.RedisContainer

Test Structure:

tests/
├── integration/
│   ├── test_database_operations.py   # Real DB tests
│   ├── test_cache_operations.py      # Real Redis tests
│   └── test_library_integrations.py  # Real library usage

Example Integration Test:

from testcontainers.postgres import PostgresContainer

def test_repository_integration():
    with PostgresContainer("postgres:15") as postgres:
        # Create real database engine
        engine = create_engine(postgres.get_connection_url())
        # Test with real database
        ...

Key Test Cases:

• [Integration1]: Test [data flow]
• [Integration2]: Test [library interaction]

End-to-End Testing

Scope: Complete API flows from request to response

Framework: pytest with TestClient (FastAPI) or requests

Test Structure:

tests/
├── e2e/
│   ├── test_api_flows.py         # Complete API workflows
│   ├── test_authentication.py    # Auth flows
│   └── test_error_scenarios.py   # Error handling

Example E2E Test:

from fastapi.testclient import TestClient

def test_user_creation_flow():
    client = TestClient(app)

    # Full flow test
    response = client.post("/users", json={"email": "[e-mail]"})
    assert response.status_code == 201

    user_id = response.json()["id"]
    get_response = client.get(f"/users/{user_id}")
    assert get_response.status_code == 200

Key Test Cases:

• [Flow1]: Test [complete user journey]
• [Flow2]: Test [error recovery]

Performance Testing

Scope: Verify performance meets non-functional requirements

Tools: pytest-benchmark, locust

• Load test [endpoint] with [N] concurrent requests

Security Testing

Scope: Verify security controls and OWASP compliance

Test Cases:

• SQL injection prevention (parameterized queries)
• XSS prevention (output sanitization)
• CSRF protection (tokens)
• Authentication bypass attempts
• Authorization boundary testing
• Secrets not in logs or responses

Test Data Management

Test Fixtures:

# Shared test fixtures
@pytest.fixture
def sample_user():
    return User(id=1, email="[e-mail]", name="Test User")

@pytest.fixture
def mock_database():
    # Create in-memory database for testing
    ...

Test Data Location: tests/fixtures/
