Send a single prompt to a Riven chat model and return the completion text. Use for quick, single-turn questions that don't need agentic research.

Create a Riven Computer research task for the given prompt, run it, poll until it completes (or times out), and return a summary of the resulting thread. Use for open-ended research questions that benefit from multi-step agentic work.

Create a Riven Computer council task, which asks multiple models to answer the same prompt and produces a synthesized verdict plus each model's individual answer. Use when you want a cross-checked or debated answer rather than a single model's view.
