Keep a research agent within a real budget

Design a bounded research agent for [QUESTION] with a maximum of [TIME OR COST BUDGET]. Identify the best primary sources to try first, what evidence is sufficient for a narrow answer, and when a second search is justified. Require source dates, quotation limits, uncertainty and a clear 'cannot verify' outcome. Return an executable plan, a stopping checklist and a final-answer template with citations. Do not claim to have searched unless tools were actually used. If the question is high stakes, specify a human review gate and avoid presenting the agent as an expert substitute.
