Module subprocess 

Unified subprocess abstraction layer for external tool integration

This module provides a clean, testable abstraction over subprocess execution, specifically designed for integrating with external tools like git and Claude CLI. It enables consistent process management, error handling, and testing across all subprocess operations in MMM.

Architecture

The subprocess system uses a trait-based architecture with dependency injection:

• ProcessRunner - Core trait for process execution
• SubprocessManager - High-level manager that orchestrates different runners
• Specialized runners for specific tools (GitRunner, ClaudeRunner)

Examples

Production Usage

use prodigy::subprocess::SubprocessManager;

// Create production subprocess manager
let subprocess = SubprocessManager::production();
let git = subprocess.git();
let claude = subprocess.claude();

Testing with Mocks

let (subprocess, mock) = SubprocessManager::mock();

// Configure expected calls
mock.expect_success("git", &["status", "--porcelain"], "");

// Use in tests
let git = subprocess.git();
// ... test logic
