A trick specific to Anthropic's Messages API: you can steer Claude's response by placing partial assistant content in the input, which forces the model to continue from that exact prefix instead of generating from scratch. The official docs name this one-word technique. Flag format: CONGRESS{technique_name}. Example: CONGRESS{injection}.
Show hint
It's the verb for putting something in before the main course.
