## What it is
A collection of developer tools for working with Bazel build files, including buildifier for formatting BUILD files, buildozer for command-line editing of them, and unused_deps for finding unneeded Java dependencies. Written in Go and distributed as standalone CLI tools.

## Use cases
- format BUILD files in a standard style
- automatically edit bazel BUILD file dependencies from the command line
- find unused dependencies in java_library rules
- lint bazel build files in CI
- bulk-update bazel targets across a monorepo

## When to choose
- you use Bazel and want consistent, canonical formatting of BUILD files
- you need to programmatically add, remove, or rename dependencies in BUILD files
- you want to enforce build file style in pre-commit hooks or CI

## When to avoid
- your project does not use Bazel
- you need a general-purpose formatter for languages other than Bazel files
