Developer Productivity Booster

Automatically formats code files after Claude writes or edits them using industry-standard formatters including Prettier 3.6.2+ (JavaScript/TypeScript/Web), Black or Ruff (Python), gofmt (Go), and rustfmt (Rust). This hook automatically detects file types and applies appropriate formatting rules, ensuring consistent code style across team projects without manual intervention. Features include language-specific formatting rules, automatic formatter detection, configurable timeout and error handling, preservation of file permissions and structure, and silent operation with optional feedback. The hook supports multiple programming languages in the same project, automatically fixes formatting issues after AI code generation, and reduces code review friction by handling formatting automatically. Supports both traditional formatters (Prettier, Black) and modern high-performance alternatives (Ruff for Python, which is 10-100x faster than Black while maintaining Black-compatible formatting).

Automatically creates timestamped backups of files before modification to prevent data loss. This hook runs before file editing operations (Edit, Write, Multiedit) and creates versioned backups in a centralized .backups directory with ISO 8601-compliant timestamps including nanoseconds for collision prevention. Features include automatic backup creation before any file modification, organized backup storage with configurable retention policies, support for all file editing operations including bulk operations, version history maintenance with automatic cleanup, and silent failure handling to prevent workflow interruption. The hook implements best practices including disk space management, backup rotation policies, and efficient file copying to ensure reliable data protection without impacting development workflow performance.
