feat(templates): implement comprehensive configuration template system

Task 8.3: Configuration Template System Implementation

Overview

Implements a comprehensive template system for AI Command Auditor that allows users to easily configure the system for different project types, environments, and security levels.

Changes Made

1. Core Template Engine (ai_command_auditor/core/templates.py)

• TemplateEngine Class: Robust template processing with variable substitution using ${variable} syntax
• Template Inheritance: Specific templates fall back to base templates for missing files
• Variable Substitution: 25+ configurable variables with comprehensive default values
• Validation System: YAML validation and content verification with detailed error reporting
• Environment Support: Development, staging, and production configurations
• Security Levels: Basic, standard, and strict security configurations

2. Template Structure (ai_command_auditor/templates/)

• Base Template: Foundation template providing core functionality
• Python Template: Python-specific security rules, virtual environment detection, framework support (Django, Flask, FastAPI)
• General Template: Language-agnostic rules for universal use
• Template Discovery: Automatic detection and validation of available templates

3. Enhanced CLI Integration (ai_command_auditor/cli/main.py)

• Enhanced init command: New options for --environment, --security-level, --team-config
• Template testing: New test-templates command for validation
• Template engine integration: Replaced old config file creation with new template system

4. Advanced Configuration Options

• Environment-Specific Settings:
  • Development: Debug logging, relaxed security, user history enabled
  • Staging: Balanced settings with moderate security
  • Production: Warning-level logging, strict security, deterministic AI
• Security Level Support:
  • Basic: Relaxed validation, longer command limits (2000 chars)
  • Standard: Balanced security settings (1000 chars)
  • Strict: Maximum security, short command limits (300 chars)
• Team Configuration: Support for team-specific settings

5. Comprehensive Testing & Validation

• Template Validation: Structure validation for all templates
• Content Validation: YAML syntax and variable resolution testing
• Environment Testing: All environment and security level combinations
• CLI Testing: New ai-auditor test-templates command with options

Testing Results

• ✅ All 3 templates (base, python, general) pass structure validation
• ✅ 100% success rate on template rendering and YAML validation
• ✅ All environment combinations work correctly
• ✅ All security levels work correctly
• ✅ Variable substitution works with proper values applied
• ✅ CLI integration functions properly with new advanced options

Usage Examples

Initialize with Python template and production environment:

ai-auditor init --template python --environment production --security-level strict

Test all templates:

ai-auditor test-templates --all-environments

Initialize with team configuration:

ai-auditor init --template general --team-config ops-team --environment staging

Files Added/Modified

• Added: ai_command_auditor/core/templates.py (203 lines)
• Added: ai_command_auditor/templates/ directory with full template structure
• Modified: ai_command_auditor/cli/main.py (integrated template engine)
• Added: Task planning documentation

Breaking Changes

None - backwards compatible with existing configurations.

Future Enhancements

• Additional project-type templates (Node.js, Rust, Security-focused)
• Custom template creation tools
• Template marketplace/sharing capabilities

Definition of Done

• Template structure created with base, python, and general templates
• TemplateEngine class with variable substitution and inheritance
• Environment-specific configurations (dev/staging/prod)
• Security level support (basic/standard/strict)
• Template validation and testing framework
• CLI integration with enhanced init command
• Comprehensive testing with 100% success rate
• Documentation and usage examples

Resolves task 8.3 from the project plan.
