Description

Implement a pre-commit hook for linting Nix files using statix and optionally deadnix.

Requirements

• Use statix for common anti-pattern detection
• Optional deadnix integration for dead code detection
• Support custom lint rules/ignores
• Auto-install linters if not available
• Provide clear, actionable lint messages

Implementation Details

• Location: hooks/nix/nix-lint.sh
• Language: bash script
• File pattern: *.nix

Testing

• Test with files containing anti-patterns
• Test with clean files
• Test custom ignore patterns
• Test linter auto-installation
• Test combined statix + deadnix mode

Configuration in .pre-commit-hooks.yaml
