Summary
A new arXiv paper describes ClawMMU, a protection layer for stateful LLM agents. The authors say agent harnesses, the software that runs the model, do not record who is allowed to act on long-term memory, which often comes from web pages and tool results. As a result, an instruction hidden in a fetched page can be treated as the user's own instruction. ClawMMU labels every memory item with its owner, scope, origins, and authority, then checks those labels when memory is used.

What happened
AI agents keep long-term memory, much of which comes from web pages and tool results. Agent harnesses, the software that runs the model, do not record who may act on this memory, so an instruction hidden in a fetched page can be treated as the user's own instruction. We propose ClawMMU, a protection layer that...
Why it matters
Developers building agents that browse the web or call tools could be affected, since memory written from untrusted sources may currently carry the same weight as user instructions. If the approach works, teams could gain a way to limit what a fetched page is allowed to make an agent do. Readers should watch for the full paper's evaluation results and whether agent frameworks adopt similar memory labeling.
