## What it is
ls-lint is an extremely fast directory and filename linter written in Go that enforces naming conventions via simple .ls-lint.yml configuration files. It supports all extensions, full unicode, and lints thousands of files in milliseconds.

## Use cases
- enforce kebab-case file names in a project
- lint directory and file naming conventions in CI
- check that test files follow camelCase naming
- validate filename structure across monorepo packages
- add filename linting as a GitHub Action
- ensure consistent naming for all file extensions

## When to choose
- you need fast filename/directory naming convention enforcement
- you want minimal setup with a single YAML config
- you need cross-platform support including npm, Homebrew, Docker, and GitHub Actions

## When to avoid
- you need to lint file contents rather than names
- you need highly custom lint rules beyond naming patterns

## Facets
- artifact type: cli-tool
- maturity: active
- function: linter, cli, file-system, developer-tools
- domain: developer-tools, files
- platform: windows, cli
- tags: filename-linter, filesystem-linter, naming-conventions, yaml-config, github-action, command-line, automation, linux, macos, docker, nodejs
