Text-Safe Is Not Tool-Safe: The Safety Layer Alignment Skips
Short summary
Models trained to refuse harmful text often still execute harmful actions through tools—the two operate on different layers. Recent research (Feb-Apr 2026) proves prompt injection, memory poisoning, and excessive agency attacks exploit this gap. Good news: action-level controls (bounded authority, least privilege, gated invocations) work, but require enforcement outside text-level alignment training.
- •Text-level safety training doesn't prevent harmful tool calls
- •Recent research shows memory poisoning and prompt injection bypass text refusals
- •Action-level controls (bounded authority, least privilege) are enforceable and effective
