Class Method Details

.agent(agent_class) ⇒ Object 



175
 
# File 'lib/legion/llm.rb', line 175

def agent(agent_class, **) = agent_class.new(**)

.ask ⇒ Object 



129
 
# File 'lib/legion/llm.rb', line 129

def ask(...) = Inference.ask(...)

.can_embed? ⇒ Boolean

These methods check Discovery first, then fall back to instance ivars set directly on LLM (ivar fallback preserves backwards compat for specs that do Legion::LLM.instance_variable_set)

Returns:

  • (Boolean)
