Declarative hyperparameter management for ML/AI experiments. Use when Claude needs to: (1) Create CLI applications with type-hinted parameters and auto-generated help (2) Configure ML training scripts with @proto.cli, @proto.prefix, or @proto decorators (3) Set up multi-namespace configurations with namespaced CLI arguments (4) Read configuration from environment variables using EnvVar (5) Create hyperparameter sweeps using piter or Sweep (6) Work with Union types for subcommand-like CLI patterns
