ghuntley/groundhog
Groundhog's primary purpose is to teach people how Cursor and all these other coding agents work under the hood. If you understand how these coding assistants work from first principles, then you can drive these tools harder (or perhaps make your own!).

What you need to know
Groundhog is an early-stage, Rust-based AI coding assistant whose primary purpose is teaching how Cursor and other coding agents work under the hood, built incrementally as part of the ghuntley.com/specs series. Positioned as a teaching tool first, not a production assistant.
Install
Build from source: git clone [repository-url] && cd Groundhog && cargo build
Usage
- •Basic command structure: Groundhog <command> [options]
- •Available commands: `Groundhog explain` (get explanations for code snippets or files)
- •Run tests with `cargo test`
Key features
- ✓Code explanation for code snippets and files
- ✓Modern architecture built with Rust for performance and reliability
- ✓Comprehensive built-in logging and telemetry for debugging and monitoring
- ✓CLI interface with detailed specs/ documentation (architecture, CLI interface, logging & telemetry, commands)
Best for
Learning agentic coding-assistant internals from first principles rather than for production use.
Caveats
- ⚠Explicitly a teaching tool first - the author recommends Goose, Roo/Cline, Aider, or AllHands for a full-blown assistant
- ⚠Early-stage/incomplete: installation instructions and license info marked "to be added", only one command implemented so far
- ⚠Author asks not to raise issues about things not working yet (community model undecided)
