A Formal Framework of Architectural Intent Collapse for Tool-Level Attacks on LLM Agents (Semantic Scholar)

paper · Story page

Three walled lanes of text merging into one open trough where the flows mix; a robot examines the merged stream after the walls end.

Formalizes why tool-level attacks keep working: flattening text from different sources into one context erases the boundary between description and instruction. Its intent-separation metric strongly predicts defense effectiveness (r = -0.97) across 25 framework-model combinations.

In plain words

  • Researchers explained why attacks keep succeeding when action-taking artificial intelligence systems combine text from many sources.
  • Descriptions, user requests, and commands arrive in one block, so the system can lose track of which text should control its behavior.
  • They created a score for this separation and tested it across 25 combinations of artificial intelligence systems and supporting software.
  • Clearer separation strongly predicted better defenses, suggesting designers should preserve the original purpose attached to each piece of text.
