Use the datamodel-optimizer agent when you need:
- Datamodel structure analysis and optimization
- Code reduction through better encapsulation
- Test/production data structure alignment
- Interface consistency improvements
- Property and method enhancement for datamodels
### Example Usage Scenarios
1. **Datamodel Analysis**: "Analyze the issue datamodel for optimization opportunities"
2. **Code Reduction**: "Optimize repetitive serialization patterns in datamodels"
3. **Test Alignment**: "Fix test/production datamodel mismatches"
4. **Interface Enhancement**: "Add convenience methods to improve datamodel usability"
## Core Capabilities
### 1. Datamodel Discovery & Analysis
- **Class Pattern Recognition**: Identify dataclasses, Pydantic models, and plain classes
- **Usage Pattern Analysis**: Map how models are used across the codebase
- **Interface Assessment**: Analyze current attribute access patterns
- **Test Pattern Detection**: Identify mock vs real object usage inconsistencies
### 2. Optimization Opportunity Detection
- **Convenience Method Gaps**: Identify missing formatting/display methods
- **Serialization Optimization**: Find verbose dict building patterns
- **Code Duplication Detection**: Locate repeated formatting logic
- **Test Alignment Issues**: Find test/production data structure mismatches
### 3. Enhancement Implementation
- **Property Addition**: Add computed properties for common operations
- **Method Generation**: Create convenience methods for frequent patterns
- **Serialization Methods**: Implement clean `to_dict()` and similar methods
- **Display Formatting**: Add formatting methods for UI/CLI display
### 4. Test Consistency Resolution
- **Mock Replacement**: Convert dictionary mocks to proper object instances
- **Test Data Factories**: Create factories for consistent test objects
- **Mock Validation**: Ensure mocks match real object interfaces
- **Test Coverage Enhancement**: Improve test reliability and maintainability
## Optimization Patterns
### Pattern 1: Property-Based Formatting
Replace scattered formatting code with centralized properties:
```python
# Before: Scattered formatting
activity.activity_type.value.title()
activity.activity_date.strftime('%Y-%m-%d') if activity.activity_date else 'N/A'
# After: Clean properties
activity.activity_type_display
activity.formatted_date
```
### Pattern 2: Serialization Method Consolidation
Replace verbose dictionary building with single method calls:
```python
# Before: Verbose dictionary building (18+ lines)
activity_data = []
for activity in activities:
data = {
'id': activity.id,
'type': activity.activity_type.value,
# ... many more lines
}
activity_data.append(data)
# After: Single method call
activity_data = [activity.to_dict() for activity in activities]
```
### Pattern 3: Business Logic Encapsulation
Replace complex conditional logic with encapsulated methods:
```python
# Before: Complex scattered logic
has_implementation = any(
'implement' in (getattr(activity, 'activity_type', None).value
if hasattr(activity, 'activity_type') and getattr(activity, 'activity_type')
else '').lower()
for activity in activities
)
# After: Simple method call
has_implementation = any(activity.has_implementation_activity() for activity in activities)
```
### Pattern 4: Test Data Consistency
Replace fragile dictionary mocks with proper object instances:
```python
# Before: Fragile dictionary mocks
mock_activities.return_value = [
{'activity_type': 'implementation', 'description': 'Implemented feature'}
]
# After: Proper objects
mock_activities.return_value = [
Activity(
activity_type=ActivityType.CREATED,
activity_details='Implemented feature'
)
]
```

Based on lessons learned from Issue #59, provides practical toolkit commands and enhanced TDD8 workflow integration to catch interface problems before implementation.
model: inherit

# Requirements Engineering and Incremental Development Planning Agent
## Purpose
Prevent interface compatibility issues and mock object mismatches encountered in Issue #59 by ensuring solid foundation planning before implementation. This agent addresses critical problems where tests create Mock() objects without spec parameters, use strings instead of enums, and assume interfaces that don't match actual domain models.
## When to Use This Agent
Use the requirements-engineering-agent when you need:
- Domain model discovery and analysis before implementation
- Interface contract verification and validation
- Mock object alignment with real domain models
- Foundation assessment before adding new features
- Prevention of interface compatibility issues
### Trigger Patterns
1. **Before New Feature Development**: "Analyze existing domain models before writing any tests"
2. **Mock Object Creation**: "Ensure mock objects match real domain model attributes using Mock(spec=)"
3. **Interface Extension**: "Plan interface changes without breaking existing code"
4. **TDD Workflow Enhancement**: "Integrate requirements validation into enhanced TDD8 process"
5. **Issue #59 Prevention**: "Prevent interface compatibility issues through systematic foundation analysis"
### Example Usage Scenarios
1. **Foundation Analysis**: "Run `make validate-requirements` before starting new feature development"
2. **Interface Verification**: "Use `python tools/requirements_engineering_toolkit.py validate-mocks` to ensure mock objects match real domain model attributes"
3. **Development Planning**: "Generate development checklist with `python tools/requirements_engineering_toolkit.py checklist --feature 'Your Feature'`"
4. **Architecture Validation**: "Plan interface evolution with `python tools/requirements_engineering_toolkit.py plan-interface --interface YourInterface`"
## Issue #59 Lessons Learned
### Critical Problems Prevented
This agent was specifically designed to prevent the interface compatibility issues encountered in Issue #59:
1. **Mock Object Mismatches**:
- Tests created `Mock()` objects without `spec=` parameter
- Mock attributes didn't match actual domain model attributes
- Used strings instead of enums (e.g., `state = "open"` instead of `IssueState.OPEN`)
- Missing required attributes like `created_at`, `updated_at`
2. **Interface Compatibility Issues**:
- Tests assumed interface methods that didn't exist in actual implementation
- Async/sync mismatch between repository (async) and expected interface (sync)
- Parameter type mismatches (string vs int for issue IDs)
3. **Bottom-Up Structure Problems**:
- Tests written without understanding existing domain model structure
- Assumptions made about interface contracts without verification
- No analysis of existing infrastructure before adding new layers
4. **Integration Planning Failures**:
- No clear plan for how new CLI would integrate with existing infrastructure
- Missing adapter layers between async repositories and sync interfaces
- No backward compatibility strategy
## Core Responsibilities
### 1. Foundation-First Analysis (Issue #59 Prevention)
- **Domain Model Discovery**: Analyze existing domain models before writing any tests using `python tools/requirements_engineering_toolkit.py analyze`
- **Interface Inventory**: Map all existing interfaces, abstract classes, and concrete implementations
- **Dependency Mapping**: Understand the complete dependency graph before adding new components
- **Foundation Assessment**: Ensure solid architectural foundations with `make validate-requirements`
### 2. Interface Contract Verification (Spec-Based Mocking)
- **Contract Verification**: Verify that all interfaces match actual implementations
- **Spec-Based Mocking**: Enforce `Mock(spec=DomainClass)` usage to prevent attribute mismatches
- **Mock Validation**: Use `python tools/requirements_engineering_toolkit.py validate-mocks --test-file tests/your_test.py`
- **Type Safety**: Ensure proper enum usage instead of strings (e.g., `IssueState.OPEN` not `"open"`)
### 3. Incremental Validation Strategy
- **Validation Checkpoints**: Define specific validation points throughout development
- **Integration Testing**: Plan integration tests before unit tests
- **Compatibility Testing**: Verify backward compatibility at each increment
- **Interface Evolution**: Plan how interfaces will evolve without breaking existing code
### 4. Test-Driven Architecture
- **Domain-First Testing**: Ensure tests reflect actual domain model requirements
- **Infrastructure Awareness**: Write tests that understand existing infrastructure patterns
- **Mock Strategy**: Create mocks that exactly match real object interfaces
- **Test Architecture**: Design test architecture that matches application architecture
## Practical Toolkit Commands
### Quick Start Commands
Before starting any new feature development, use these commands to validate foundations:
```bash
# 1. Validate requirements and foundations
make validate-requirements
# 2. Analyze existing domain models and interfaces
python tools/requirements_engineering_toolkit.py analyze
# 3. Plan interface evolution for specific interfaces
python tools/requirements_engineering_toolkit.py plan-interface --interface YourInterface
# 4. Generate development checklist for new features
python tools/requirements_engineering_toolkit.py checklist --feature "Your Feature"
# 5. Validate that test mocks match real objects
python tools/requirements_engineering_toolkit.py validate-mocks --test-file tests/your_test.py
```
### Integration with Existing Workflow
```makefile
# Enhanced Makefile targets
tdd-start: validate-requirements
python tddai_cli.py tdd-start $(NUM)
validate-requirements:
python tools/requirements_engineering_toolkit.py analyze
python tools/requirements_engineering_toolkit.py validate-mocks
```
### Pre-commit Validation
```bash
# Add to pre-commit hooks to prevent Issue #59 problems
make validate-requirements
python -m pytest tests/test_mock_compatibility.py
```
## Core Methodologies
### 1. Domain Model First (DMF) Approach
Before writing any tests or implementation:
```bash
# 1. Analyze existing domain models
grep -r "class.*:" domain/*/models.py
grep -r "def " domain/*/models.py
# 2. Map existing interfaces
find . -name "*.py" -exec grep -l "class.*ABC\|@abstractmethod" {} \;
# 3. Understand data flow
grep -r "Repository\|Service" infrastructure/ domain/
```
**Workflow:**
1. **Domain Discovery**: Map all existing domain models and their attributes
2. **Interface Analysis**: Understand all abstract base classes and interfaces
3. **Dependency Review**: Trace dependencies between layers
4. **Contract Documentation**: Document all interface contracts before modification
### 2. Interface-Contract-First (ICF) Testing
```python
# WRONG - Assumption-based mocking
mock_issue = Mock()
mock_issue.number = 59
mock_issue.title = "Test"
mock_issue.state = "open" # String instead of enum!
# RIGHT - Contract-verified mocking
from domain.issues.models import Issue, IssueState, Label
mock_issue = Mock(spec=Issue)
mock_issue.number = 59
mock_issue.title = "Test Issue"
mock_issue.state = IssueState.OPEN # Proper enum
mock_issue.labels = []
mock_issue.created_at = datetime.now(timezone.utc)
mock_issue.updated_at = datetime.now(timezone.utc)
```
**Workflow:**
1. **Spec-Based Mocking**: Always use `spec=` parameter with actual classes
2. **Attribute Verification**: Verify all mock attributes match real object attributes
3. **Type Consistency**: Ensure mock data types match domain model types
4. **Enum Handling**: Use actual enums instead of string representations
### 3. Incremental Architecture Validation (IAV)
**Validation Checkpoints:**
- **Checkpoint 1**: Domain model compatibility
- **Checkpoint 2**: Interface contract verification
- **Checkpoint 3**: Mock object alignment
- **Checkpoint 4**: Integration test validation
- **Checkpoint 5**: End-to-end workflow testing
**Implementation:**
```bash
# Validation script template
validate_domain_compatibility() {
python -c "
from domain.issues.models import Issue
from markitect.issues.base import IssueBackend
# Verify interface compatibility
"
}
validate_mock_alignment() {
# Run tests that verify mocks match real objects
python -m pytest tests/test_mock_compatibility.py
}
```
### 4. Foundation-First Development (FFD)
**Principle**: Build on solid foundations before adding new layers.
**Workflow:**
1. **Foundation Assessment**: Verify existing infrastructure is solid
2. **Interface Stability**: Ensure base interfaces won't change during development
3. **Dependency Injection**: Plan dependency injection patterns
4. **Layer Separation**: Maintain clear separation between architectural layers
## Analysis Tools
### 1. Domain Analysis Tools
```bash
# Domain Model Inspector
analyze_domain_models() {
echo "=== Domain Model Analysis ==="
find domain/ -name "models.py" -exec echo "File: {}" \; -exec grep -n "class\|def " {} \;
}
# Interface Contract Checker
check_interface_contracts() {
echo "=== Interface Contract Analysis ==="
grep -r "@abstractmethod\|ABC" . --include="*.py"
}
# Mock Compatibility Validator
validate_mocks() {
echo "=== Mock Compatibility Check ==="
python -c "
import inspect
from domain.issues.models import Issue
print('Issue attributes:', [attr for attr in dir(Issue) if not attr.startswith('_')])
"
}
```
### 2. Test Architecture Framework
```python
# Test Base Classes for Interface Compliance
class DomainModelTestBase:
"""Base class ensuring tests match domain models."""
def setUp(self):
self.validate_test_setup()
def validate_test_setup(self):
"""Verify test setup matches actual domain models."""
pass
def create_mock_with_spec(self, domain_class):
"""Create spec-compliant mock."""
return Mock(spec=domain_class)
class IntegrationTestBase:
"""Base class for integration tests."""
def setUp(self):
self.verify_infrastructure_availability()
def verify_infrastructure_availability(self):
"""Ensure required infrastructure is available."""
pass
```
### 3. Mock Validation Framework
```python
class MockValidator:
"""Validates that mocks match real objects."""
@staticmethod
def validate_mock_spec(mock_obj, real_class):
"""Validate mock object matches real class specification."""
mock_attrs = set(dir(mock_obj))
real_attrs = set(dir(real_class))
missing_attrs = real_attrs - mock_attrs
extra_attrs = mock_attrs - real_attrs
if missing_attrs:
raise MockSpecError(f"Mock missing attributes: {missing_attrs}")
return True
@staticmethod
def validate_mock_types(mock_obj, real_instance):
"""Validate mock attribute types match real object types."""
for attr_name in dir(real_instance):
if not attr_name.startswith('_'):
real_value = getattr(real_instance, attr_name)
mock_value = getattr(mock_obj, attr_name, None)
if mock_value is not None and type(mock_value) != type(real_value):
raise MockTypeError(f"Type mismatch for {attr_name}")
```
## Example Workflows
### 1. Adding New CLI Command Workflow
**Phase 1: Foundation Analysis**
```bash
# 1. Analyze existing CLI structure
find cli/ -name "*.py" -exec grep -l "click\|@cli" {} \;
# 2. Understand existing domain models
python -c "
from domain.issues.models import Issue
import inspect
print(inspect.signature(Issue.__init__))
"
# 3. Map existing repository interfaces
grep -r "class.*Repository" infrastructure/
```
**Phase 2: Interface Contract Definition**
```python
# Define interface contract first
class IssueBackend(ABC):
@abstractmethod
def list_issues(self, state: Optional[str] = None) -> List[Issue]:
"""List issues with optional state filter."""
pass
@abstractmethod
def get_issue(self, issue_id: str) -> Issue:
"""Get specific issue by ID."""
pass
```
**Phase 3: Test Architecture Design**
```python
# Design tests that match actual interfaces
class TestIssuesCLIGroup:
def setup_method(self):
# Use actual domain model for mock spec
self.mock_issue = Mock(spec=Issue)
self.mock_issue.number = 59
self.mock_issue.title = "Test Issue"
self.mock_issue.state = IssueState.OPEN # Use actual enum
self.mock_issue.labels = []
self.mock_issue.created_at = datetime.now(timezone.utc)
self.mock_issue.updated_at = datetime.now(timezone.utc)
```
### 2. Domain Model Extension Workflow
**Phase 1: Impact Analysis**
```bash
# Find all usages of the domain model
grep -r "Issue" . --include="*.py" | grep -v __pycache__
# Check existing tests
grep -r "Issue" tests/ --include="*.py"
# Analyze database schemas
grep -r "Issue" infrastructure/repositories/
```
**Phase 2: Backward Compatibility Planning**
```python
# Plan extension that maintains compatibility
@dataclass
class Issue:
# Existing attributes (DO NOT CHANGE)
number: int
title: str
state: IssueState
labels: List[Label]
created_at: datetime
updated_at: datetime
# New attributes (with defaults for compatibility)
body: str = "" # Add with default
assignees: List[str] = field(default_factory=list)
html_url: str = ""
```
## Enhanced TDD8 Workflow Integration
**Enhanced TDD8 Workflow with Requirements Engineering:**

result = run_test_command(f"make {test_target}")
return result
except PytestError as e:
# Handle specific pytest errors
return handle_pytest_error(e)
except Exception as e:
# Handle general errors
return handle_general_error(e)
```
### TDD8 Workflow Integration
#### Red Phase Agent Pattern
```python
def execute_red_phase_tests(test_file: str) -> bool:
"""Execute tests for TDD red phase - expect failures."""
result = execute_tests_safely("test-quick")
if result.has_failures:
logger.info("✅ Red phase successful - tests failing as expected")
return True
else:
logger.warning("⚠️ Red phase issue - tests not failing")
return False
```
#### Green Phase Agent Pattern
```python
def execute_green_phase_tests() -> bool:
"""Execute tests for TDD green phase - expect success."""
result = execute_tests_safely("test")
if result.all_passed:
logger.info("✅ Green phase successful - all tests passing")
return True
else:
logger.error("❌ Green phase failed - implementation needs work")
return False
```
## Enhanced Pytest Configuration
```ini
