# Requirements Engineering Agent Integration Guide
## Quick Start
Add these commands to your development workflow to prevent interface compatibility issues and mock object mismatches:
```bash
# Before starting any new feature
make validate-requirements
# When planning interface changes
python tools/requirements_engineering_toolkit.py plan-interface --interface YourInterface
# Before writing tests
python tools/requirements_engineering_toolkit.py checklist --feature "Your Feature"
# When creating mocks
python examples/issue_59_prevention_demo.py # See correct patterns
```
## Integration with Existing Workflow
### 1. Enhanced Makefile Targets
Add these targets to your `Makefile`:
```makefile
# Requirements Engineering Integration
validate-requirements:
@echo "🔍 Validating project requirements and foundations..."
python tools/requirements_engineering_toolkit.py analyze
check-interface-compatibility:
@echo "🔌 Checking interface compatibility..."
python tools/requirements_engineering_toolkit.py plan-interface --interface $(INTERFACE)
generate-dev-checklist:
@echo "📋 Generating development checklist..."
python tools/requirements_engineering_toolkit.py checklist --feature "$(FEATURE)"
# Enhanced TDD workflow
tdd-start: validate-requirements
@echo "🚀 Starting TDD workflow with requirements validation..."
python tddai_cli.py tdd-start $(NUM)
# Pre-commit validation
pre-commit-validate:
make validate-requirements
python -m pytest tests/test_mock_compatibility.py -xvs
```
### 2. Enhanced TDD8 Workflow
The TDD8 workflow is enhanced with requirements engineering checkpoints:
```
1. ANALYZE - Analyze existing domain models and interfaces
2. ISSUE - Understand requirements in architectural context
3. TEST - Write tests that match actual interfaces
4. RED - Verify tests fail for the right reasons
5. GREEN - Implement with interface compatibility
6. REFACTOR - Maintain interface contracts
7. DOCUMENT - Update interface documentation
8. PUBLISH - Commit with interface change documentation
```
### 3. TodoWrite Integration
Enhanced TodoWrite with validation checkpoints:
```python
# Example enhanced todo list
todos = [
{
"content": "Analyze existing domain models",
"status": "pending",
"activeForm": "Analyzing existing domain models",
"checkpoint": "foundation_analysis"
},
{
"content": "Define interface contracts",
"status": "pending",
"activeForm": "Defining interface contracts",
"checkpoint": "interface_definition"
},
{
"content": "Create spec-compliant mocks",
"status": "pending",
"activeForm": "Creating spec-compliant mocks",
"checkpoint": "mock_validation"
}
]
```
## Pre-Development Checklist
Before starting any new feature development:
### Foundation Analysis
- [ ] Run `make validate-requirements`
- [ ] Review existing domain models in target area
- [ ] Map current interface contracts
- [ ] Understand dependency relationships
### Interface Planning
- [ ] Define new interface contracts
- [ ] Check compatibility with existing interfaces
- [ ] Plan evolution strategy for existing interfaces
- [ ] Document interface specifications
### Test Strategy
- [ ] Plan test architecture that matches application architecture
- [ ] Identify domain models that will need mocking
- [ ] Plan integration test points
- [ ] Define validation checkpoints
## Mock Object Guidelines
### ✅ Correct Mock Patterns
```python
from unittest.mock import Mock
from domain.issues.models import Issue, IssueState, Label
from datetime import datetime, timezone
# CORRECT: Use spec= parameter
mock_issue = Mock(spec=Issue)
mock_issue.number = 59
mock_issue.title = "Test Issue"
mock_issue.state = IssueState.OPEN # Use actual enum
mock_issue.labels = []
mock_issue.created_at = datetime.now(timezone.utc)
mock_issue.updated_at = datetime.now(timezone.utc)
```
### ❌ Incorrect Mock Patterns
```python
# WRONG: No spec parameter
mock_issue = Mock()
mock_issue.number = 59
mock_issue.state = "open" # String instead of enum!
# Missing required attributes
# WRONG: Assumption-based attributes
mock_issue.some_attribute_that_doesnt_exist = "value"
```
### Mock Validation Script
Create `tests/test_mock_compatibility.py`:
```python
import pytest
from unittest.mock import Mock
from domain.issues.models import Issue, IssueState
from datetime import datetime, timezone
class TestMockCompatibility:
"""Validate that test mocks match actual domain models."""
def test_issue_mock_has_all_required_attributes(self):
"""Test that Issue mocks include all required attributes."""
# Create a real Issue to get expected attributes
real_issue = Issue(
number=1,
title="Real Issue",
state=IssueState.OPEN,
labels=[],
created_at=datetime.now(timezone.utc),
updated_at=datetime.now(timezone.utc)
)
# Create mock with spec
mock_issue = Mock(spec=Issue)
mock_issue.number = 1
mock_issue.title = "Mock Issue"
mock_issue.state = IssueState.OPEN
mock_issue.labels = []
mock_issue.created_at = datetime.now(timezone.utc)
mock_issue.updated_at = datetime.now(timezone.utc)
# Verify critical attributes match
real_attrs = {attr for attr in dir(real_issue) if not attr.startswith('_')}
mock_attrs = {attr for attr in dir(mock_issue) if not attr.startswith('_')}
missing_attrs = real_attrs - mock_attrs
critical_missing = [attr for attr in missing_attrs
if not callable(getattr(real_issue, attr))]
assert not critical_missing, f"Mock missing critical attributes: {critical_missing}"
def test_issue_mock_uses_correct_types(self):
"""Test that Issue mocks use correct types."""
mock_issue = Mock(spec=Issue)
mock_issue.state = IssueState.OPEN # Should be enum, not string
assert isinstance(mock_issue.state, IssueState), "State should be IssueState enum"
```
## Interface Evolution Guidelines
### Planning Interface Changes
1. **Analyze Current Usage**:
```bash
# Find all usages of the interface
grep -r "YourInterface" . --include="*.py"
```
2. **Plan Backward Compatibility**:
```python
# Example: Adding new method while maintaining compatibility
class YourInterface(ABC):
# Existing methods (don't change signatures)
@abstractmethod
def existing_method(self, param: str) -> str:
pass
# New methods (with default implementations if possible)
def new_method(self, param: str) -> Optional[str]:
"""New method with default implementation for compatibility."""
return None # Safe default
```
3. **Create Migration Plan**:
- Phase 1: Add new interface methods with defaults
- Phase 2: Update implementations incrementally
- Phase 3: Add deprecation warnings to old methods
- Phase 4: Remove deprecated methods after transition period
### Interface Compatibility Checking
```bash
# Check if new interface is compatible with existing implementations
python tools/requirements_engineering_toolkit.py plan-interface \
--interface NewInterface \
--existing-implementations ExistingRepo,AnotherRepo
```
## Common Patterns and Solutions
### Pattern 1: Plugin Interface Design
```python
# Base interface that matches existing repository patterns
class IssueBackend(ABC):
def __init__(self, config: Dict[str, Any]):
self.config = config
@abstractmethod
def list_issues(self, state: Optional[str] = None) -> List[Issue]:
pass
@abstractmethod
def get_issue(self, issue_id: str) -> Issue:
pass
# Implementation that adapts async repository
class GiteaPlugin(IssueBackend):
def __init__(self, config: Dict[str, Any]):
super().__init__(config)
self.repository = GiteaIssueRepository(self._create_connection_manager())
def list_issues(self, state: Optional[str] = None) -> List[Issue]:
# Adapter pattern: async -> sync
return asyncio.run(self.repository.get_issues(state=state))
```
### Pattern 2: Domain Model Extension
```python
# Extending domain model while maintaining compatibility
@dataclass
class Issue:
# Existing attributes (don't change order or remove)
number: int
title: str
state: IssueState
labels: List[Label]
created_at: datetime
updated_at: datetime
# New attributes with defaults for backward compatibility
body: str = ""
assignees: List[str] = field(default_factory=list)
html_url: str = ""
```
### Pattern 3: Test Architecture Alignment
```python
# Test structure that matches application architecture
class TestIssuePluginManager:
def setup_method(self):
# Use real domain models for mocks
self.mock_issue = Mock(spec=Issue)
self.mock_backend = Mock(spec=IssueBackend)
# Configure mocks with realistic data
self._configure_realistic_mocks()
def _configure_realistic_mocks(self):
"""Configure mocks to match real object behavior."""
self.mock_issue.number = 59
self.mock_issue.state = IssueState.OPEN
self.mock_issue.created_at = datetime.now(timezone.utc)
# ... all required attributes
```
## Error Prevention Checklist
### Before Writing Tests
- [ ] Analyze target domain models with `python tools/requirements_engineering_toolkit.py analyze`
- [ ] Understand existing interface contracts
- [ ] Plan mock strategy using `Mock(spec=ActualClass)`
- [ ] Verify enum usage instead of strings
### Before Implementation
- [ ] Check interface compatibility
- [ ] Plan async/sync adapter layers if needed
- [ ] Verify backward compatibility strategy
- [ ] Document interface contracts
### Before Committing
- [ ] Run mock compatibility tests: `pytest tests/test_mock_compatibility.py`
- [ ] Validate interface evolution plan
- [ ] Check that no existing tests are broken
- [ ] Update documentation for interface changes
## Troubleshooting Common Issues
### Issue: Mock doesn't match domain model
**Solution**: Use `Mock(spec=ActualClass)` and include all required attributes
### Issue: Enum vs string mismatch
**Solution**: Import and use actual enums: `from domain.issues.models import IssueState`
### Issue: Async/sync interface mismatch
**Solution**: Add adapter layer to convert between async and sync interfaces
### Issue: Missing attributes in mock
**Solution**: Run domain analysis to see all required attributes, ensure mock includes them
### Issue: Interface breaking changes
**Solution**: Use evolution plan with backward compatibility and deprecation period
## Integration with Existing Tools
### CLI Commands
```bash
# Add to existing CLI
markitect validate-requirements # Run foundation analysis
markitect check-interfaces # Verify interface compatibility
markitect plan-migration # Plan interface evolution
markitect validate-mocks # Check mock compatibility
```
### IDE Integration
- Add pre-commit hooks for requirements validation
- Configure IDE to run mock compatibility tests
- Set up interface change detection
### CI/CD Integration
```yaml
# Add to GitHub Actions / CI pipeline
- name: Validate Requirements
run: make validate-requirements
- name: Check Mock Compatibility
run: python -m pytest tests/test_mock_compatibility.py
```
This integration ensures that the Requirements Engineering Agent becomes a natural part of the development workflow, preventing the interface compatibility issues encountered in Issue #59 and improving overall code quality and development efficiency.

# Requirements Engineering and Incremental Development Planning Sub-Agent
## Executive Summary
This specialized sub-agent was designed to prevent the interface compatibility issues and mock object mismatches encountered during Issue #59 debugging session. It provides a systematic approach to requirements engineering that ensures solid foundations before implementation.
## Problem Analysis: What Went Wrong in Issue #59
During the Issue #59 debugging session, several critical problems were identified:
### 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

- Would have mapped existing `GiteaIssueRepository` interface
### 2. Interface Planning
- Would have identified async/sync mismatch between repository and plugin interface
- Would have planned adapter layer needed
- Would have defined clear interface contracts
### 3. Mock Validation
- Would have enforced `Mock(spec=Issue)` usage
- Would have caught attribute mismatches before running tests
- Would have ensured enum usage instead of strings
### 4. Integration Strategy
- Would have planned how CLI integrates with existing infrastructure
- Would have identified reusable components
- Would have maintained backward compatibility

# Requirements Engineering and Incremental Development Planning Agent
## Overview
A specialized sub-agent designed to prevent interface compatibility issues and mock object mismatches by ensuring solid foundation planning before implementation. This agent addresses the core problems encountered during Issue #59 development where tests assumed interfaces that didn't match the actual domain models.
## Agent Responsibilities
### 1. Bottom-Up Structure Planning
- **Domain Model Discovery**: Analyze existing domain models before writing any tests
- **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 before building new features
### 2. Interface Contract Definition
- **Contract Verification**: Verify that all interfaces match actual implementations
- **Mock Alignment**: Ensure mock objects exactly match real domain model attributes and methods
- **API Compatibility**: Check that new interfaces are compatible with existing infrastructure
- **Type Safety**: Ensure all type hints and signatures are consistent across layers
### 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
## 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
## Tools and Frameworks
### 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. Interface Evolution Manager
```python
class InterfaceEvolutionManager:
"""Manages interface changes without breaking compatibility."""
def plan_interface_change(self, interface_name, changes):
"""Plan interface changes with backward compatibility."""
pass
def validate_compatibility(self, old_interface, new_interface):
"""Validate that new interface is backward compatible."""
pass
def generate_migration_plan(self, changes):
"""Generate step-by-step migration plan."""
pass
```
### 4. 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)
```
**Phase 4: Incremental Implementation**
- Implement abstract base class
- Create plugin system
- Add CLI commands
- Integrate with existing infrastructure
### 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 = ""
```
**Phase 3: Migration Strategy**
```python
# Create migration tests
class TestIssueModelMigration:
def test_old_constructor_still_works(self):
"""Ensure old constructor calls still work."""
issue = Issue(
number=1,
title="Test",
state=IssueState.OPEN,
labels=[],
created_at=datetime.now(timezone.utc),
updated_at=datetime.now(timezone.utc)
)
assert issue.body == "" # Default value
```
### 3. Plugin System Development Workflow
**Phase 1: Architecture Planning**
```python
# Define plugin interface based on existing patterns
class IssueBackend(ABC):
"""Abstract base class matching existing repository patterns."""
def __init__(self, config: Dict[str, Any]):
self.config = config
@abstractmethod
def list_issues(self, state: Optional[str] = None) -> List[Issue]:
pass
```
**Phase 2: Integration Strategy**
```python
# Plan integration with existing infrastructure
class GiteaPlugin(IssueBackend):
def __init__(self, config: Dict[str, Any]):
super().__init__(config)
# Reuse existing infrastructure
self.repository = GiteaIssueRepository(
connection_manager=self._create_connection_manager()
)
def list_issues(self, state: Optional[str] = None) -> List[Issue]:
# Use existing async infrastructure
return asyncio.run(self.repository.get_issues(state=state))
```
## Integration Points with Existing Development Workflow
### 1. TDD8 Enhancement
**Enhanced TDD8 Workflow:**
1. **ANALYZE** - Analyze existing domain models and interfaces
2. **ISSUE** - Understand requirements in context of existing architecture
3. **TEST** - Write tests that match actual interfaces
4. **RED** - Verify tests fail for right reasons
5. **GREEN** - Implement with interface compatibility
6. **REFACTOR** - Maintain interface contracts
7. **DOCUMENT** - Update interface documentation
8. **PUBLISH** - Commit with interface change documentation
### 2. TodoWrite Integration
```python
# Enhanced TodoWrite with validation checkpoints
todos = [
{
"content": "Analyze existing Issue domain model",
"status": "pending",
"activeForm": "Analyzing existing Issue domain model",
"checkpoint": "domain_analysis"
},
{
"content": "Define IssueBackend interface contract",
"status": "pending",
"activeForm": "Defining IssueBackend interface contract",
"checkpoint": "interface_definition"
},
{
"content": "Create spec-compliant mocks",
"status": "pending",
"activeForm": "Creating spec-compliant mocks",
"checkpoint": "mock_validation"
}
]
```
### 3. CLI Help Integration
```bash
# Enhanced CLI with validation commands
markitect validate-interfaces # Check interface compatibility
markitect analyze-domain # Analyze domain models
markitect check-mocks # Validate mock objects
markitect plan-migration # Plan interface migrations
```
## Success Metrics
### 1. Interface Compatibility
- **Zero Mock Mismatches**: All mocks must match actual object interfaces
- **Type Safety**: 100% type consistency between tests and implementation
- **Backward Compatibility**: No breaking changes to existing interfaces
### 2. Test Quality
- **Domain Model Alignment**: Tests reflect actual domain model structure
- **Integration Coverage**: All integration points tested with real interfaces
- **Mock Validation**: All mocks validated against real object specifications
### 3. Development Efficiency
- **Reduced Debugging**: Fewer interface-related bugs
- **Faster Development**: Less time spent fixing mock mismatches
- **Better Architecture**: Cleaner interface design and evolution
## Prevention of Issue #59 Problems
This agent would have prevented the Issue #59 problems by:
1. **Domain Model Analysis**: Would have discovered the actual Issue model has `IssueState` enum, not string
2. **Interface Inventory**: Would have mapped existing GiteaIssueRepository before designing plugin interface
3. **Mock Validation**: Would have caught mock attribute mismatches before running tests
4. **Integration Planning**: Would have planned how new CLI integrates with existing infrastructure
5. **Contract Verification**: Would have ensured all interfaces match actual implementations
The result would be a solid, well-planned implementation that builds on existing foundations rather than making incorrect assumptions about interfaces and domain models.
