  • Error handling tests

Core Components

1. DevelopmentPatternAnalyzer

Analyzes development patterns and workflows to identify trends and insights.

Methods:

  • analyze_workflow_patterns() - Analyzes commit, file, and testing patterns
  • calculate_velocity_metrics() - Calculates productivity metrics
  • analyze_collaboration_patterns() - Analyzes team collaboration
  • analyze_project_trends() - Tracks project evolution over time

Data Models:

  • DevelopmentPattern - Represents detected patterns
  • VelocityMetrics - Development velocity and productivity metrics
  • CollaborationPattern - Team collaboration patterns
  • ProjectTrend - Project evolution trends

2. ProactiveSuggestionEngine

Generates proactive suggestions based on patterns and predictions.

Methods:

  • generate_task_recommendations() - Recommends next tasks
  • detect_potential_issues() - Predicts future issues
  • identify_optimization_opportunities() - Finds optimization opportunities

Data Models:

  • PredictiveSuggestion - Represents a proactive suggestion
  • PredictionType - Types of predictions (next_task, potential_issue, etc.)
  • ConfidenceLevel - Confidence levels for predictions

3. PredictiveDevelopmentAssistant

Main coordinator for all predictive capabilities.

Methods:

  • analyze_development_context() - Comprehensive context analysis
  • generate_proactive_suggestions() - Generate all types of suggestions
  • get_prediction_accuracy_metrics() - Track prediction accuracy

Usage Example

from src.codegenie.core.predictive_engine import PredictiveDevelopmentAssistant

# Initialize assistant
assistant = PredictiveDevelopmentAssistant()

# Analyze development context
project_data = {
    'commits': [...],
    'file_changes': [...],
    'test_data': {...},
    'team_data': {...},
    'historical_data': [...]
}

analysis = await assistant.analyze_development_context(project_data)

# Generate proactive suggestions
context = {
    'current_files': ['src/main.py'],
    'recent_changes': [...],
    'project_state': {'test_coverage': 60}
}

suggestions = await assistant.generate_proactive_suggestions(context)

# Review suggestions sorted by priority
for suggestion in suggestions:
    print(f"{suggestion.title} (Priority: {suggestion.priority}/10)")
    print(f"Actions: {suggestion.suggested_actions}")

Performance

  • Pattern Analysis: < 1 second for typical projects
