pub fn get_model(fallback: Option<&str>, prefer_env: bool) -> Option<String>Expand description
Resolves a model name with optional environment lookup.
When prefer_env is true, a readable OPEN_AGENT_MODEL takes precedence over
fallback. Otherwise only fallback is considered. Neither value is validated;
no value yields None.
use open_agent::get_model;
assert_eq!(get_model(Some("my-model"), false).as_deref(), Some("my-model"));
let from_environment = get_model(None, true);
