setup-formatting — Claude Code command: what it does, how to install
A Claude Code command that configures code formatters and enforces project style rules. Useful when setting up Prettier, Black, or rustfmt with git hooks.
npx claude-code-templates@latest --command setup/setup-formattingWhat setup-formatting 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.
What it helps with
- 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 for the agent
- Run
/setup-formatting --pythonto configure Black and project rules - Set up Prettier formatting with
/setup-formatting --typescript - Configure multi-language formatting via
/setup-formatting --multi-language
