# Stateless chat

> Asks CodeAlive's built-in research agent a question and returns a synthesized, evidence-grounded answer. Each call is stateless: no conversation is stored, so include all relevant prior findings, artifact identifiers, constraints, and scope in `question`. This is the highest-latency, highest-cost tool — when orchestrating your own agent loop, prefer the direct search and read tools and reserve `chat` for when a delegated end-to-end answer is explicitly wanted.
