immosquare-cleaner formats Ruby, ERB, JS/TS, Rust, Go, TOML, Markdown, Shell, JSON, YAML and CSS files with one consistent house style, delegating each format to the right tool (RuboCop, erb_lint, ESLint, rustfmt, gofmt, taplo, shfmt, Prettier). Run it on a file, a whole repository, on save, or as a Claude Code, Cursor or Gemini CLI hook so every file an AI agent writes comes out formatted.
