Difficulty-Routed Control in Customer-Service  \nOperations 1  \nQian Chen† Chengyuan Liu‡ Xin Yu‡  \n†Department of Supply Chain and Information Systems  \n‡Department of Statistics  \nThe Pennsylvania State University  \n{quc20, cjl6934, [xmy5152}@psu.edu](xmy5152}@psu.edu)  \nAbstract  \nAutonomous customer-service agents are shifting from conversational interfaces toward operational execution roles: they retrieve firm records, apply service policies, and execute backend writes such as refunds, cancellations, exchanges, order modifications, and reservation changes. This shift creates a service-control problem: firms must keep routine service fast and low-friction while preventing operational errors on requests where customer instructions, policy constraints, firm records, and backend writes interact. We propose a difficultyrouted service-control architecture that asks when service agents should reconsider before acting. A lightweight router keeps routine sessions on a low-cost baseline path and routes operationally coupled sessions to an escalated workflow. The escalated path uses conflict-aware communication and write-triggered reconsideration to concentrate deliberation and safeguards before consequential backend writes, rather than applying additional control uniformly across all service sessions. We evaluate the architecture on human-verified retail and airline tasks from τ 2-bench. In retail, the method improves reliability consistently on service requests with operational conflict. Routing evidence shows that stronger control is directed toward conflicted requests rather than broadly applied to routine ones. Dialogue and tool-use profiles suggest that gains do not come from indiscriminate interaction expansion or broader tool chains; instead, added turns and tool calls support evidence gathering, write separation, and pre-write reconsideration. Case-level evidence shows that the escalated workflow preserves fallback plans, binds retrieved records to the correct action, sequences writes, and decomposes multi-entity requests. Airline results extend the same service-control logic to reservation operations. The paper contributes a service-control perspective on agentic AI by showing how routing and write-triggered reconsideration can selectively allocate communication, deliberation, and safeguards across heterogeneous customer-service requests.  \nKeywords Agentic AI; Customer-Service Operations; Service Control; Difficulty Routing; Operational Conflict  \n1 All authors contributed equally and are listed alphabetically by last name.  \nA Preprint – July 3, 2026  \n1 Introduction  \nGenerative AI is changing customer-service operations from a communication technology into an execution technology. Early service chatbots primarily answered questions, provided policy information, or recommended next steps. Newer autonomous service agents can converse with customers, retrieve account or order information, apply business rules, and execute backend writes—state-changing updates to firm records, such as returns, exchanges, cancellations, address changes, refunds, and reservation updates (Huang and Rust, 2024; Wang et al., 2026) . This shift creates opportunities for faster and more scalable service delivery, but it also changes the nature of operational risk. When an AI system can directly modify service records, an error is no longer merely an incorrect response; it can become an incorrect refund, cancellation, exchange, booking change, or customer commitment.  \nThis operational risk is difficult to manage because customer-service requests are heterogeneous. Many requests are routine: a customer asks for a straightforward return, a simple cancellation, a policy explanation, or the status of an order. These cases should be handled quickly, at low cost, and with minimal customer friction. Other requests create operational conflict: the correct action depends o","cbCaihL5GPfCZUSW","https://ap.wps.com/l/cbCaihL5GPfCZUSW","pdf",672951,2,1,47,"English","en",105,"# Introduction\n## Operational risk from execution\n## Heterogeneous customer requests\n## Service-control tradeoff\n# Difficulty-routed service-control architecture","[{\"question\":\"What problem does the paper address in autonomous customer-service operations?\",\"answer\":\"It addresses how to allocate control when agents execute backend actions, where errors can directly cause incorrect refunds, cancellations, exchanges, or reservation changes.\"},{\"question\":\"How does difficulty routing decide when an agent should reconsider?\",\"answer\":\"A lightweight router keeps routine sessions on a low-cost path and routes operationally coupled or conflict-prone sessions to an escalated workflow that triggers reconsideration before consequential writes.\"},{\"question\":\"What do the evaluations show about where the improvements come from?\",\"answer\":\"The reliability gains concentrate on service requests with operational conflict;
