What you'll build

You'll build a universal command-line companion that understands natural-language requests and turns them into the exact arguments for the tool you're already using. Say "drop the last commit" while invoking it for Git and it proposes git reset --soft HEAD^, ready to run.

The utility works as a plus-suffixed wrapper you can call alongside your everyday commands (think git+, ffmpeg+, rg+), always showing a clear preview and asking for confirmation before executing. It makes powerful actions quick, transparent, and safe.

Learning objectives

✓Set up a Rust project with async capabilities

✓Parse command-line arguments using the plus-suffix convention

✓Craft and fill a prompt template for an LLM

✓Integrate with an OpenAI-compatible API via the rig crate

✓Split LLM output into shell-safe arguments

✓Spawn and manage child processes asynchronously

✓Propagate exit codes for correct pipeline behavior

✓Add an interactive confirmation dialog for safety

Prerequisites

▸Basic Rust syntax (structs, impl blocks, Result)

▸Familiarity with Cargo and dependencies

▸Understanding of async/await concepts

▸Basic command-line experience

FAQ

Is this a video course?

No. You work through the project step by step in your browser, and the reference code for each step saves to your disk — yours to run and keep locally.

Do I need to install anything?

No. The playground runs entirely in your browser — no toolchain or local setup required.

Can I try it before subscribing?

Yes. Preview steps are available without a subscription so you can see the format and quality first.

What do I get with full access?

Every step unlocked, the Workbench app, a snapshot for each step, jump-to-any-step navigation, and all new playground releases.

Does it work with an AI agent like Claude or Codex?

Yes. You can work through a playground solo or alongside an AI agent.

Is there reference code?

Yes. Every step has a complete reference solution you can compare against.
