arb is a schema-driven code generation tool that turns structured YAML into fully working CLIs and tooling.

The idea is to make the schema and data the source of truth, with validation and deterministic output, instead of hand-written glue code.

I included a concrete Rust example that generates a Clap-based CLI with global flags, leaf commands, and nested subcommands (e.g. remote add/list), all from data.

This is pre-alpha and focused on clarity and correctness rather than features. Feedback welcome.
