codecrafters command [options]

codecrafters is the command-line interface for the CodeCrafters platform, which provides challenges for building real-world software from scratch. Projects include building your own Redis, Git, Docker, SQLite, and other complex systems.
The CLI handles authentication, test execution, and solution submission. It integrates with the CodeCrafters platform to track progress through multi-stage challenges, where each stage introduces new requirements and complexity.
Challenges are completed by implementing code that passes increasingly sophisticated tests. The local test command provides quick feedback during development, while submit validates against the full test suite on CodeCrafters' servers.
