"""
Validate All YAML Workflow Configurations

This tool performs strict validation on all YAML workflow configuration files
in the yaml_instance/ directory. It ensures configuration integrity and prevents
runtime errors by catching issues early in the development process.

Purpose:
- Validates YAML syntax and schema compliance for all workflow configurations
- Prevents invalid configurations from causing runtime failures
- Essential for CI/CD pipelines to ensure code quality
- Provides detailed error reporting for debugging

Usage:
    python tools/validate_all_yamls.py
    # or via Makefile:
    make validate-yamls
