## What it is
Mrm is a command line tool that applies codemods to project configuration files like package., .gitignore, and .eslintrc, keeping them in sync with minimal, formatting-preserving changes. It ships with tasks for popular tools (ESLint, Prettier, lint-staged, GitHub Actions) and supports custom tasks and shareable presets via npm.

## Use cases
- scaffold a new JavaScript project config in one command
- add eslint and prettier config to an existing project
- generate license, readme, and contributing files
- update or migrate configs of an old project
- write custom codemods for  yaml ini markdown config files
- share team config tasks as npm presets

## When to choose
- you need to update existing config files without overwriting them
- you want minimal diffs that preserve file formatting
- you maintain many open source projects needing consistent configs
- you prefer codemod-style updates over template-based generators

## When to avoid
- you only need to generate a brand-new project from scratch
- you work outside the JavaScript/Node.js ecosystem
- you need a full project scaffolding tool with interactive prompts

## Facets
- artifact type: cli-tool
- maturity: active
- function: cli, developer-tools, workflow-automation, configuration-management, boilerplate
- domain: developer-tools, web-development
- platform: cli, cross-platform
- tags: codemod, config-files, scaffolding, task-runner, presets, dotfiles, automation, command-line, nodejs
