## What it is
gts is Google's TypeScript style guide packaged as a zero-configuration CLI tool that bundles ESLint linting, Prettier formatting, and an opinionated tsconfig.json. Running `gts init` sets up lint, fix, clean, and compile scripts in a project with automatic code fixing.

## Use cases
- enforce a consistent TypeScript code style across a team without writing lint rules
- auto-format and auto-fix TypeScript files with one command
- set up linting and formatting in a new TypeScript project quickly
- stop style debates in code review by adopting an opinionated standard
- use Google's TypeScript style as a shareable ESLint config
- add clean and compile scripts wired to the TypeScript compiler

## When to choose
- you want zero-config, opinionated TypeScript style enforcement backed by Google
- you want linting and formatting from a single dependency and CLI
- you're starting a new TypeScript project and want sensible defaults immediately
- you want an ESLint config you can extend with custom rules later

## When to avoid
- your team already has its own ESLint/Prettier configuration and style guide
- you need fine-grained control over every lint rule from day one
- you're linting plain JavaScript without TypeScript
- you need a style guide with configurable options rather than an opinionated default
