## What it is
pre-commit is a framework for managing and maintaining multi-language Git pre-commit hooks. It automatically installs and runs hooks written in any language before each commit, catching issues like formatting errors and debug statements before code review.

## Use cases
- run linters automatically before every git commit
- share linting hooks across multiple projects
- use linters written in other languages without installing their toolchains
- check for trailing whitespace and missing semicolons on commit
- enforce code style checks before code review
- manage pre-commit hook dependencies without root access

## When to choose
- you want consistent automated checks on every commit across a team
- your project uses linters written in multiple languages
- you want to share hook configurations across many repositories
- you want to catch trivial style issues before human review

## When to avoid
- you only need a CI pipeline check without local git hooks
- your team commits infrequently and hooks would slow the workflow
- you need hooks for non-git version control systems

## Facets
- artifact type: framework
- maturity: stable
- function: linter, developer-tools, cli, code-review, formatter
- domain: developer-tools, version-control
- platform: python, cross-platform, cli
- tags: git-hooks, pre-commit-hooks, code-quality, multi-language, linting, command-line, automation
