Genesis

An idea becomes a plan, and the plan becomes a Python CLI repo that installs and passes its own tests. Anything that isn't a Python CLI still gets a plan — just no generated code, and the repo says so. Source and eval numbers on GitHub.

Scaffold a sample plan

No API key, no account. This is the half the eval measures: a plan in, a repo out.

      Genesis asks clarifying questions before it plans, so this takes a few rounds. Each one is a
      call to Anthropic and takes 15–30 seconds.
    


    

      Your key is used for this request and nothing else. It is never stored,
      logged, or written to disk — it is forwarded to Anthropic and discarded. The requests go
      straight from your browser to the API. If you would rather not paste a key into a web page,
      install the CLI and it never leaves your
      machine.
