Features

The AI Toolkit installer configures security and quality guardrails across supported AI development tools:

Code Quality & Standards

• Conventional Commits - Enforced commit message format via git hooks
• Linting & Formatting - ESLint, Prettier, and language-specific linters
• Type Safety - TypeScript strict mode and type checking
• Code Coverage - >80% test coverage targets with automated reporting

These rules are enforced at both the repository and AI tooling levels through automated hooks, ensuring consistent team practices and standards.

Security Controls

• Secret Management - 1Password CLI integration, prevents secret commits
• Security Scanning - Semgrep static analysis for vulnerability detection
• Tool Allowlists - Restrict AI tool permissions via .claude/settings.json
• PreToolUse Hooks - Validate and audit AI tool actions before execution

These controls limit AI agent access to GitHub operations. While you retain full access using your SSH key, AI agents can only read repositories and create pull requests. Semgrep static analysis prevents secrets from being committed to Git. The 1Password integration requires biometric authentication at runtime to access secrets mapped from environment files, ensuring you're always notified when AI agents request secret access.

Permission & Access

• MCP Server Policies - Controlled access to Model Context Protocol servers
• Privilege Escalation - User-space first, explicit sudo requests when needed
• API Key Management - Environment-based configuration, never committed

Common MCP servers are pre-installed for task management, repository operations, and tool integrations. AI agents require explicit user approval to access resources or perform actions.

AI-Specific Protections

• No AI Attribution - Blocked "Co-authored-by: AI" in commits via hooks
• Prompt Injection Guards - Input validation in AI-facing interfaces
• Action Logging - Comprehensive logging for AI operations and decisions

Development Workflow

• Git Integration - Safe branching, PR templates, and workflow automation
• Dependency Validation - Task dependency checking and circular reference prevention
• Cross-Platform Safety - Consistent behavior across macOS, Linux, and Windows

These guardrails are automatically configured during installation and can be customized per project via configuration files in .claude/, .taskmaster/, and root-level dotfiles.
