TDD Guard is an automated Test-Driven Development enforcement tool for Claude Code. Validates coding practices and prevents implementations that bypass testing requirements via Claude Code hooks. Supports TypeScript, JavaScript, Python, PHP, Go, Rust, and Storybook with multi-framework integration (Jest, Vitest, pytest, PHPUnit). Enforces test-first development, blocks over-engineering beyond test scope, and includes lint integration for refactoring. Customizable rules with session-level toggle control.
