Screen Before You Serve: Simulation for Production Customer Experience AI Agents at 140M Scale

The paper introduces a hypothesis-driven simulation workflow that screens customer experience (CX) agents before deployment, using synthetic customers and simulated tool outputs to emulate multi-step interactions without accessing production backends. Applied to Nubank’s high-volume Card Delivery and Card Management chat-support agents, the simulation’s binary evaluator scores correlated strongly with production results, and simulation-guided iterations raised transactional net promoter score by 36.69 points in a live A/B test. Additionally, screening over 16,000 simulated conversations helped select a model that increased self‑service rate by 8.82 percentage points without harming net promoter score, demonstrating that simulation enables extensive model exploration safely.

RedditPersona: A Modular Framework for Community-Conditioned LLM Adaptation from Reddit

arXiv:2606. 06027v1 Announce Type: cross Abstract: Community-conditioned language model adaptation requires choices about data collection, community definition, and evaluation that are currently made independently in each study, making it hard to compare assumptions or reuse artifacts.

DocuTeam: Mixed-Initiative Multi-Agent Discussions around Evolving Documents

DocuTeam is a mixed‑initiative multi‑agent discussion system that allows both users and agents to start and steer conversations around evolving documents. Agents monitor changes to the document and proactively initiate or redirect discussions, while users can shape the dialogue or adopt agent suggestions. In a within‑subjects study with 20 participants, DocuTeam produced outcomes that were rated as more novel, relevant, and specific compared to a baseline, without increasing cognitive load.

TxSum: User-Centered Ethereum Transaction Understanding with Micro-Level Semantic Grounding

TxSum introduces a user-centered approach to understanding Ethereum transactions by providing structured, risk-aware explanations grounded at the token‑flow level. The authors built a dataset of 187 complex transactions with 2,375 token‑flow annotations and transaction‑level summaries, and developed MATEX, a multi‑agent framework that retrieves external knowledge and audits explanations for factual consistency. MATEX outperforms existing baselines, improving user comprehension from 52.9% to 76.5% and increasing malicious‑transaction rejection from 36.0% to 88.0% while keeping false‑rejection rates low.
