## What it does

This command automates code formatting setup across a project. It begins by scanning the directory with `find`. The agent looks for JavaScript, TypeScript, Python, or Rust files. It also inspects existing configs such as `.prettierrc`, `pyproject.toml`, or `rustfmt.toml`, alongside package manifests.

Next, it installs appropriate tools like Prettier, Black, or rustfmt. The setup defines indentation and line length rules. Beyond basic configuration, it prepares `.vscode/settings.json` settings and pre-commit hooks for CI validation.

Claude Code needs `Read`, `Write`, `Edit`, and `Bash` permissions to run this command. Without `Bash` access, package installation fails. You can target specific stacks with flags like `--python`, `--typescript`, or `--multi-language`.

## Install

### Claude Code (native platform)

1. **claude-code-templates**
```bash
npx claude-code-templates@latest --command setup/setup-formatting
```

2. **Manually: put the files in place**

### Codex

**Manually: put the files in place**
- File: `~/.codex/prompts/setup-formatting.md` — Call it with /prompts:setup-formatting. Codex marks this format deprecated in favour of skills

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/prompts/setup-formatting.prompt.md`

### Gemini CLI

**Manually: put the files in place**
- File: `.gemini/commands/setup-formatting.toml` — Gemini stores commands as TOML: the prompt text goes into the prompt field

## When to use it
- install and configure Prettier, Black, or rustfmt
- standardize indentation, quotes, and line length rules
- automate style checks inside pre-commit hooks and CI pipelines
- configure format-on-save settings in `.vscode/settings.json`

## Example prompts
- Run `/setup-formatting --python` to configure Black and project rules
- Set up Prettier formatting with `/setup-formatting --typescript`
- Configure multi-language formatting via `/setup-formatting --multi-language`

# 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.
