What

My personal coding assistant, built to solve the following problems in commercial and open source coding agents:

1. Abstractions, features, and UI/UX that stand between coding agents and LLMs.
2. Black box prompt engineering and vendor lock-in.
3. Keeping my judgement of an LLM's reckoning grounded, by having full source control over how I interact with coding models.

How

Just one simple REPL-style main loop with a minimal set of tools.

Want to try?

1. Make sure you have a Rust toolchain or Nix installed.

2. Run:

   ./ol login opencode-go  # recommended
   ./ol

Development

nix develop
cargo check
