SimXAI: A Simple Drop-in Layer Increases Interaction Quality and Understanding in Conversational XAI

SimXAI is a lightweight, LLM‑centric conversational layer that replaces traditional intent recognition, dialogue management, and template‑based response modules in GUS‑style ConvXAI agents. By using a single tool‑calling LLM to interface with existing XAI resources, it provides a modular interface that improves function‑selection accuracy, faithfulness, and handling of context‑dependent requests. In a user study, substituting SimXAI for the conversational layer of the TalkToModel agent led to more accurate task completion in fewer turns, demonstrating enhanced conversational quality while preserving faithfulness.

The Power of Meta Access in the Software of the Future --- Demonstrated on LLM Chat UIs and Chat AI

The paper proposes ‘meta access’—a structured, permissioned view of an interface’s state—to enhance large language model chat UIs. It outlines a ladder of access levels, from feature tutoring to full orchestration, and demonstrates the concept with the Meta Chat prototype, which uses summaries, settings, and message links to enable reversible changes and a browsable tutorial library. Meta access aims to transform chat from a single conversation window into a control layer for the entire workspace while addressing risks such as grounding, privacy, and prompt injection.

Agent Seer: Synthesizing Scenarios from Specification Understanding

Agent Seer is a pipeline that automatically synthesizes realistic evaluation scenarios for AI agents that use external tools, using only the tool’s specification (function names, natural‑language descriptions, and typed parameter schemas). Starting from a single Model Context Protocol (MCP) specification, it enriches raw schemas, generates graded scenarios with synthetic tool outputs, and expands them into mock‑data‑grounded multi‑turn dialogues that demonstrate strong tool‑calling correctness and conversational coherence. Across seven diverse MCP specifications, the pipeline achieves high quality, with parameter‑schema complexity emerging as the main driver of quality variation and argument‑value accuracy identified as the dominant failure mode.
