  def caveats
    <<~EOS
      To use git-ca, you need a local GGUF model (llama.cpp format).

      The tool will automatically download the default model
      (unsloth/gemma-3-270m-it-GGUF) on first run, or you can:
        - Place GGUF files in ./models directory
        - Place GGUF files in ~/.cache/git-ca/models directory
        - Run 'git ca model' to select a model manually

      To set up a default model, run:
        git ca model

      Note: git-ca uses local llama.cpp inference (no remote API calls).
