## Overview

This repository is a Zig shell challenge starter. The documented workflow begins with a user entering commands, which the `src/main.zig` entry point interprets and executes as builtins or external programs. Parsing and REPL behavior are documented capabilities, but source excerpts were unavailable, so implementation-level wiring beyond the stated entry point is not inferred.

Main entry points: [`src/main.zig`](https://github.com/chaituvarma-109/codecrafters-shell-zig/blob/master/src/main.zig) (Shell entry)
