Risk
Untested Reasoning-Chain Manipulation
Description
Goal hijacking, intent manipulation, and reasoning-chain attacks are not exercised โ leaving the most agent-specific failure modes undetected.
Example
An attacker plants instructions in retrieved content that subtly shift the agent's interpretation of its goal across multiple turns; functional tests pass while the agent quietly executes the attacker's intent.
