The exercism command-line tool is the official CLI for the Exercism platform, helping programmers improve skills via coding exercises, automated analysis, and mentorship.

It streamlines downloading exercises across 50+ language tracks, editing locally, submitting solutions, viewing feedback, and managing progress.

Key workflows:
• Configure with your API token.
• Install tracks to a local workspace (git-based).
• Download specific exercises.
• Submit files for review.
• Browse iterations or mentor requests.

Version 3 (Rust-based) uses a unified workspace directory for all tracks, improving organization and offline work. Requires internet for sync operations but supports local editing.

Ideal for TDD practice and deliberate practice in real-world scenarios.

Requires API token from exercism.org/account/api_token. Most commands need internet; workspace tracks use git. Subcommands have additional options (use --help).

Download binaries from exercism.org/cli; or brew install exercism/tap/exercism (macOS), apt install exercism (some distros). Run exercism version to verify.

exercism configure (enter token).
