+# Setup Code Formatting
+
+Configure comprehensive code formatting with consistent style enforcement: **$ARGUMENTS**
+
+## Current Project State
+
+- Languages detected: !`find . -name "*.js" -o -name "*.ts" -o -name "*.py" -o -name "*.rs" | head -5`
+- Existing formatters: @.prettierrc or @pyproject.toml or @rustfmt.toml
+- Package manager: @package.json or @requirements.txt or @Cargo.toml
+- IDE config: @.vscode/settings.json or @.editorconfig
+
+## Task
+
+Setup comprehensive code formatting system with automated enforcement and team consistency:
+
+**Language Focus**: Use $ARGUMENTS to configure JavaScript/TypeScript, Python, Rust, or multi-language formatting
+
+**Formatting Setup**:
+1. **Tool Installation** - Prettier, Black, rustfmt, language-specific formatters and plugins
+2. **Configuration** - Style rules, line length, indentation, quotes, trailing commas, language-specific options
+3. **IDE Integration** - Editor extensions, format-on-save, keyboard shortcuts, workspace settings
+4. **Automation** - Pre-commit hooks, CI/CD formatting checks, automated formatting scripts
+5. **Team Sync** - Shared configurations, style guides, enforcement policies, onboarding documentation
+6. **Validation** - Formatting verification, CI integration, team compliance monitoring
+
+**Advanced Features**: Custom rules, framework-specific formatting, performance optimization, incremental formatting.
+
+**Consistency**: Cross-platform compatibility, team standardization, legacy code migration strategies.
+
+**Output**: Complete formatting system with automated enforcement, team configurations, and style compliance monitoring.
