gnn-shared-utilities

name	gnn-shared-utilities
description	GNN shared utility functions and helper modules. Use when working with common pipeline utilities, logging helpers, file I/O wrappers, path management, or pipeline template infrastructure.

GNN Shared Utilities

Purpose

Provides shared utility functions, helper modules, and common infrastructure used across all 25 pipeline steps. Includes logging, error handling, configuration, dependency validation, and the standardized pipeline template.

Key Commands

# Utils is a shared library — not run directly but imported by all pipeline steps.
# Validate pipeline dependencies
python -c "from utils import validate_pipeline_dependencies; validate_pipeline_dependencies()"

# Check optional dependency status
python -c "from utils import get_dependency_status; print(get_dependency_status())"

# Run pipeline health check
python -c "from utils import generate_pipeline_health_report; print(generate_pipeline_health_report())"

Visual Logging Features

• 🎨 Color-coded status indicators (green=success, yellow=warning, red=error)
• 📊 Progress bars and completion indicators
• 🔢 Correlation ID tracking for debugging
• 📋 Structured summary tables
• ⏱️ Performance timing and memory tracking

MCP Tools

This module registers tools with the GNN MCP server (see mcp.py):

• get_environment_info
• get_file_info
• get_logging_info
• get_system_info
