Beyond Outcomes: Toward Process-Aware Software Agents

Autonomous programming agents are commonly evaluated by whether they solve software tasks, providing limited insight into the execution processes that lead to success or failure. We present a process-centric approach to evaluating agent behavior through trajectories. We introduce Graphectory, which captures the structu...

Graphectory Viewer: A Tool for Process-Centric Analysis of Agentic Software Trajectories

We present Graphectory Viewer, a web-based tool for interactive, process-centric analysis of software-agent trajectories. Building on the Graphectory representation introduced in our previous work, Graphectory Viewer transforms heterogeneous raw trajectories into phase-aware graphs that connect low-level execution deta...

Online Monitoring and Corrective Steering of Programming Agents

LivePlan decouples judging from advising: a deterministic, rule-based monitor examines general signals over the trajectory to detect issues without invoking an LLM, and only when an issue is detected does it consult an advisor LLM for a high-level, next-step correction.
