TelemetryFlow Core - Module Standardization System

A comprehensive quality gates and automation system that ensures TelemetryFlow Core modules meet all standardization requirements defined in the Kiro steering guidelines.

Overview

The Module Standardization System provides automated validation, documentation generation, test coverage enforcement, and continuous improvement processes for all TelemetryFlow Core modules. Version 1.1.4 includes fully implemented documentation generation, test coverage analysis, and test structure validation with 100% test coverage and production-ready checkpoint validation.

Features

  • ✅ Quality Gate Validation: Automated checks for documentation, test coverage, and file structure
  • ✅ Documentation Generation: Automated README, API docs, ERD, and DFD generation
  • ✅ Test Coverage Analysis: Layer-specific coverage validation with detailed reporting
  • ✅ Test Structure Validation: Directory organization, naming conventions, and pattern validation
  • ✅ Memory-Optimized Processing: Efficient file system operations with depth limits
  • 🚧 File Structure Validation: DDD compliance checking and automated fixes (in progress)
  • 🚧 CLI Tools: Command-line interface for all standardization operations (planned)
  • 🚧 Continuous Improvement: Metrics tracking and improvement recommendations (planned)

Architecture

The system follows a layered architecture with clear separation of concerns:
