Task 8.2: CLI Interface Development

Overview

This PR implements Task 8.2 - CLI Interface Development from the AI Command Auditor project plan. All required CLI commands have been fully implemented with comprehensive functionality and robust error handling.

✅ Implemented CLI Commands

1. ai-auditor init

• ✅ Initialize AI Command Auditor in any project
• ✅ Template support: python, node, rust, general, security
• ✅ Custom config directory option (--config-dir)
• ✅ Force overwrite option (--force)
• ✅ Creates complete .ai-auditor/ directory structure
• ✅ Template-specific configurations and security rules

2. ai-auditor setup-hooks

• ✅ Setup git hooks for command validation
• ✅ Integrates with existing scripts/setup-hooks.sh when available
• ✅ Falls back to basic hook creation when needed
• ✅ Force reinstall option (--force)
• ✅ Creates functional pre-commit and pre-push hooks

3. ai-auditor check-command

• ✅ Test command validation against current rules
• ✅ Integrates with existing legacy command checker
• ✅ Falls back to security validation when needed
• ✅ JSON output option (--json)
• ✅ Context option (--context) for additional analysis
• ✅ Proper error handling with fallback mechanisms

4. ai-auditor validate-setup

• ✅ Verify installation and configuration
• ✅ Checks directory structure completeness
• ✅ Validates configuration files
• ✅ Tests git hooks installation
• ✅ Verifies pre-commit tool availability
• ✅ Tests command validation functionality
• ✅ Comprehensive status reporting

5. ai-auditor update-config

• ✅ Update configuration templates to latest version
• ✅ Template switching capability (--template)
• ✅ Automatic backup creation (timestamped)
• ✅ Force update option (--force)
• ✅ Preserves user customizations when possible

🎨 Key Features

• Colorized Output: Green checkmarks, red errors, yellow warnings, blue info
• Template System: Different configurations for Python, Node.js, Rust, general, and security-focused projects
• Security Integration: Full integration with existing security validation modules
• AI Integration: Seamless integration with OpenAI-based command checking
• Configuration Management: User-accessible .ai-auditor/ directory structure
• Fallback Mechanisms: Graceful degradation when components are unavailable
• Multiple Output Formats: Human-readable and JSON output options
• Error Handling: Comprehensive error handling with verbose mode support

🔧 Integration with Existing Modules

The CLI seamlessly integrates with all existing functionality:

• Legacy Command Checker: Uses scripts/python/core/check_command.py when available
• Security Module: Integrates with scripts/python/core/security.py for validation
• Configuration System: Uses the existing ai_command_auditor/core/config.py
• Git Hooks: Leverages existing scripts/setup-hooks.sh when present

🧪 Testing Results

All CLI commands were thoroughly tested and verified:

• ✅ Initialization: Successfully creates project structure with Python template
• ✅ Security Validation: Correctly blocks dangerous commands like rm -rf /
• ✅ Safe Commands: Properly validates and passes safe commands like ls -la
• ✅ Hook Setup: Creates functional git hooks in test environment
• ✅ Configuration Updates: Successfully switches between templates with backup
• ✅ JSON Output: Properly formatted JSON responses for programmatic use
• ✅ Setup Validation: Comprehensive validation of installation status

📋 Usage Examples

# Initialize with Python template
ai-auditor init --template python

# Setup git hooks
ai-auditor setup-hooks

# Test command validation
ai-auditor check-command "ls -la"
ai-auditor check-command "rm -rf /" --json

# Validate installation
ai-auditor validate-setup

# Update configuration
ai-auditor update-config --template security

🎯 Definition of Done - ACHIEVED

All CLI commands work as specified in the task requirements:

• ✅ ai-auditor init - Creates project configuration
• ✅ ai-auditor setup-hooks - Installs git hooks
• ✅ ai-auditor check-command "test" - Validates commands
• ✅ ai-auditor validate-setup - Verifies installation

📝 Files Changed

• ai_command_auditor/cli/main.py - Complete CLI implementation
• docs/planning/task-planning/task-8-devcontainer-integration.md - Task status update

🔗 Next Steps

Task 8.2 is now complete and ready for the next phase:

• Task 8.3: Configuration Template System
• Task 8.4: Installer Script Creation
• Task 8.5: GitHub Pages Documentation

✨ Ready for Review

This PR implements all functionality required for Task 8.2 with comprehensive testing, proper error handling, and seamless integration with existing modules. The CLI is now ready for production use and provides a solid foundation for the remaining tasks in the AI Command Auditor project.
