LCMCP Pattern

The Loosely Coupled Modular Composition Pattern (LCMCP) is a fundamental architectural pattern used throughout the GitHub Toolkit. This pattern ensures components can be combined effectively while maintaining independence and flexibility.

Pattern Overview

LCMCP enables the toolkit's modular architecture by defining how components at different layers interact while remaining loosely coupled.

Note: This documentation is currently incomplete. The LCMCP pattern is referenced throughout the codebase but needs detailed documentation from the project maintainers.

Key Principles

Based on the name and usage throughout the toolkit, LCMCP appears to follow these principles:

Loosely Coupled

  • Components depend on interfaces, not implementations
  • Changes in one component don't require changes in others
  • Clear boundaries between different architectural layers

Modular

  • Each component has a single, focused responsibility
  • Components can be developed and tested independently
  • Functionality is organized into discrete, reusable modules

Composition

  • Complex functionality built by combining simpler components
  • Higher-level components orchestrate lower-level ones
  • Flexible assembly of capabilities to create solutions

Usage in the Toolkit

The LCMCP pattern is evident in several areas:

Layer Composition

  • Atoms (generated actions) compose into Molecules (composite actions)
  • Molecules compose into Organisms (workflows)
  • Each layer builds upon the previous while remaining independent

Action Design

  • Actions have clear input/output interfaces
  • Actions can be combined in different workflows
  • Implementation details are hidden behind interfaces

FCM Bridge System

  • FCM definitions are loosely coupled from implementations
  • Generated actions are modular and composable
  • Bridge system enables flexible composition of capabilities

Documentation Needed

This pattern requires additional documentation covering:

  • Detailed pattern definition and rules
  • Implementation guidelines for each layer
  • Examples of proper LCMCP application
  • Anti-patterns and what to avoid
  • Testing strategies for loosely coupled systems
