EchoPath: Execution-Level Replayable Memory for GUI Agents

Read the original on arXiv AI →

EchoPath is a model‑agnostic framework that transforms validated GUI interaction trajectories into standardized, parameter‑controlled memories, enabling agents to replay specific GUI actions deterministically. Each memory records task intent, preconditions, input parameters, GUI evidence, validation provenance, and lifecycle state, and uses an image‑based target‑reaiming algorithm to adjust coordinates for the current screen before execution. Experiments on real computer‑use tasks show that EchoPath cuts median token cost by over 90 % and median execution time by about 60 %.

AstronOS: A Unified Execution Model and Runtime for Long-Horizon Agentic Systems

arXiv:2608. 16381v1 Announce Type: new Abstract: Agentic systems often organize execution and state around a single conversation, model invocation, or agent instance, even when real work spans many calls and stages.

GUI vs. CLI: Execution Bottlenecks in Screen-Only and Skill-Mediated Computer-Use Agents

arXiv:2606. 24551v1 Announce Type: new Abstract: Computer-use agents can execute software tasks through either graphical interfaces or programmatic command interfaces, but existing evaluations confound interaction modality with differences in tasks, initial states, verifiers, and permitted actions.

Efficient GUI Agents: A Systems Survey of Observation, Memory, Action, and Runtime Optimization

The paper surveys efficient GUI agents, emphasizing that practical deployment requires more than task success—it must also minimize context, computation, action budget, and runtime overhead. It reviews key efficiency dimensions—observation, memory, action, and planner/system—and identifies recurring strategies such as selective reading, global-to-local visual allocation, recoverable memory, verification-aware control, and hybrid runtimes. The authors highlight open challenges, including accurate verifier cost accounting, benchmark comparability, and co-design of observation, memory, and execution layers under real latency and privacy constraints.

Grounding Agent Memory: Environment-Probing Curation for Enterprise Agents

The paper introduces environment‑probing curation, a deployment‑compatible method that equips asynchronous curator agents with read‑only world tools to verify, scope, and refresh candidate memories without retraining models. In a GitHub Copilot‑based harness, this approach improves pass rates on CLBench from 39% to 73%, boosts reward metrics, and reduces both query counts and task‑agent costs. Across six APEX management‑consulting tasks, the method consistently outperforms baselines, yielding higher rewards and fewer tool calls while maintaining a compact task‑time interface.
