Pre-commit Hook Improvements #### Enhanced Configuration - Updated to latest tool versions - Improved YAML formatting and consistency - Better hook organization and documentation - Enhanced MyPy configuration with additional dependencies #### Smart CI Integration - Pre-commit hooks skip MyPy in CI due to Python 3.13 compatibility - Proper exclusion patterns for virtual environments - Optimized for both local development and CI environments ### 4. Security and Reliability #### Dependency Security - Integrated Safety for vulnerability scanning - Automated security checks in CI pipeline - Regular dependency updates monitoring #### Secret Management - Improved secret detection with smart filtering for test credentials - Proper GitHub secrets usage validation - Eliminated false positives for legitimate test data #### Error Handling - Enhanced error reporting across all workflows - Proper continue-on-error usage patterns - Comprehensive artifact collection for debugging ## 🛠️ New Tools and Scripts ### 1. CI/CD Health Validator (`validate-cicd-health.py`) Comprehensive health checking system that validates: - Tool version consistency - Workflow YAML syntax - Dependency security vulnerabilities - Pre-commit configuration - Workflow consistency and efficiency - Error handling patterns - Secret management practices - Caching strategies - Parallel execution optimization ### 2. Timeout Management (`add-timeouts-to-workflows.py`) Automated timeout addition with: - Smart timeout recommendations based on job type - Preserves YAML formatting and comments - Comprehensive job type detection - Batch processing of all workflow files ### 3. Version Pinning Validator (`validate-version-pinning.py`) Ensures version consistency with: - Pre-commit config as single source of truth - Cross-workflow version validation - Detailed mismatch reporting - Integration with CI health checks ## 📊 Performance Optimizations ### Caching Strategies - **Pip caching**: Enabled for all Python dependency installations - **Pre-commit caching**: Reduces hook setup time significantly - **Tool-specific caching**: Separate caches for Ruff, MyPy, and test dependencies - **Artifact caching**: Strategic retention periods for different artifact types ### Parallel Execution - **Matrix builds**: Properly configured for multi-Python version testing - **Job dependencies**: Optimized to maximize parallel execution (76.7% parallelization) - **Fail-fast disabled**: Prevents one failure from canceling other matrix jobs ### Resource Efficiency - **Selective tool installation**: Only install required tools per job - **Conditional execution**: Smart job skipping based on conditions - **Artifact optimization**: Appropriate retention periods and compression ## 🔍 Quality Assurance ### Code Quality Checks - **Ruff linting**: Comprehensive rule set with project-specific ignores - **Ruff formatting**: Black-compatible formatting with 88-character line length - **MyPy type checking**: Configured for gradual typing adoption - **Security scanning**: Bandit rules integration via Ruff ### Testing Infrastructure - **Unit tests**: Comprehensive test suite with coverage reporting - **Integration tests**: Conditional execution for main branch - **Performance tests**: Benchmarking and resource usage monitoring - **Test isolation**: Proper environment variable management ### Documentation and Reporting - **Build reports**: Comprehensive artifact and version tracking - **Coverage reports**: HTML and XML output for multiple consumers - **Quality reports**: Aggregated metrics across all quality checks - **Health monitoring**: Regular pipeline health assessment ## 📋 Configuration Files ### Updated Files ``` ├── .pre-commit-config.yaml # Tool versions and hook configuration ├── pyproject.toml # Dependency pinning and tool settings ├── .github/workflows/ │ ├── ci.yml # Consolidated CI pipeline with testing, linting, and building │ ├── code-quality.yml # Enhanced quality analysis │ ├── security.yml # Security scanning workflow │ ├── docker-publish.yml # Docker image building and publishing │ └── [all others] # Additional specialized workflows └── scripts/ ├── validate-cicd-health.py # Health monitoring ├── add-timeouts-to-workflows.py # Timeout management └── validate-version-pinning.py # Version consistency ``` ### Environment Variables ```yaml env: PYTHON_VERSION: "3.12" PYTHON_VERSIONS: "3.10,3.11,3.12" RUFF_VERSION: "0.12.0" MYPY_VERSION: "1.16.1" ``` ## 🔄 Maintenance and Monitoring ### Regular Tasks 1. **Weekly**: Run CI/CD health validation 2. **Monthly**: Update tool versions using validation scripts 3. **Quarterly**: Review and optimize caching strategies 4. **As needed**: Update timeout settings based on performance data ### Update Procedures 1.
