# panproto-cli
[](https://crates.io/crates/panproto-cli)
Command-line interface for panproto. The binary is called `schema`.
Provides subcommands for schema validation, migration checking, breaking change detection, record lifting, protolens-based data conversion, and schematic version control.
## Installation
```sh
# macOS (Homebrew)
brew install panproto/tap/panproto-cli
# Linux / macOS (shell installer)
# Windows (PowerShell)
# From source (any platform with Rust)
cargo install panproto-cli
```
## Usage
```sh

schema init # initialize repo, auto-detect packages
schema add schema.json # stage a JSON schema
schema add crates/panproto-gat/ # stage a directory (parsed via tree-sitter)
