Signal-Driven Observation for Long-Horizon Web Agents
Quick Answer
The paper introduces Signal-Driven Observation (SDO) for web agents, addressing context degradation by selectively querying the DOM for relevant elements only when triggered by specific events, enhancing reasoning efficiency during long-horizon tasks.
Key Points
- SDO reduces context degradation by querying only relevant DOM elements.
- Triggered by events like URL changes or action failures, SDO optimizes observation frequency.
- The approach emphasizes observation compression as a key design decision.
- Open problems related to SDO are identified for further community exploration.

arXiv:2606. 06708v1 Announce Type: new Abstract: Web agents operating over long horizons ingest raw DOM and accessibility trees -- routinely tens of thousands of tokens -- at every action step, causing progressive context degradation that erodes reasoning well before tasks complete. We argue that this coupling of observation frequency to action frequency is an architectural mistake. …
