This guide helps AI agents work efficiently on the `brush` codebase by providing essential context about architecture, patterns, and development workflows.
## 1. Architecture Overview & Navigation
### Project Structure
The brush project is organized into several key crates:
- **`brush-core/`**: Core shell functionality, builtins, and runtime
- **`brush-parser/`**: Shell script parsing (AST generation)
- **`brush-builtins/`**: Implementation of shell builtins (e.g.,.github/copilot-instructions.mdTool: github-copilot# GitHub Copilot Coding Agent Instructions for brush
## Project Overview
**brush** (Bourne Rusty Shell) is a POSIX- and bash-compatible shell implemented in Rust. It's a multi-crate workspace (~60K lines of Rust code) targeting Linux, macOS, and WSL, with experimental Windows and WASM support. The project emphasizes compatibility testing against bash as an oracle.
**Key Stats:** Rust 2024 edition, MSRV 1.88.0, 5 main crates, 1500+ compatibility test cases, published to crates.io.
