It breaks your request into its real sub-questions, grounds each one in actual tools and sources, then hands back a route you can rerun and audit. Bring it decisions, plans, research, anything with more than one moving part. Solved routes get reused, so answers come back faster and cheaper as the library grows. 50 free solves to start.",
