## What it is
lint-staged is an npm CLI tool that runs arbitrary shell tasks, such as formatters and linters, against only the files staged in git. It is typically wired into a pre-commit hook so code quality checks run on just the files being committed.

## Use cases
- run prettier only on staged files before commit
- lint changed files in a pre-commit git hook
- prevent unformatted code from being committed
- run eslint on files about to be committed
- speed up linting by checking only staged files
- auto-fix lint errors before each git commit

## When to choose
- you want fast pre-commit checks limited to staged files
- you already use husky or git hooks and want to run formatters/linters on commit
- you want to auto-fix and re-stage files before they enter the repo

## When to avoid
- you need to lint the entire codebase in CI rather than staged files
- your project does not use git
- you only want a simple check script without configuration

## Facets
- artifact type: cli-tool
- maturity: stable
- function: linter, formatter, developer-tools, ci-cd, cli
- domain: developer-tools, version-control, web-development
- platform: cli, cross-platform
- tags: git-hooks, pre-commit, staged-files, code-quality, prettier, eslint, husky, automation, nodejs
