Context as an Environment: Programmatic Context Management for Long-Horizon Agents (arXiv)
paper · Story page
Scroll backs each agent session with an append-only event log and a persistent sandboxed Python kernel, so tool outputs and history bind to variables instead of being serialized into every prompt. Only explicitly printed projections enter the working view, and evicted spans stay recoverable through landmarks tied to exact log addresses.
In plain words
- Researchers created Scroll to help an agent, an artificial intelligence system that takes actions, handle tasks with histories too large to read at once.
- Scroll keeps every session event in a permanent record, while a protected coding workspace saves useful information under names.
- The system shows the artificial intelligence only selected information, while older material remains available through exact references.
- Long-running assistants can recover overlooked details later without repeatedly loading their entire history.
