Your AI Assistant Is Quietly Working for Someone Else
Anthropic is injecting promotional tips into Claude Code’s tool output, turning a trusted AI agent into a dual-purpose advertising vehicle. The ad was ‘reasonably unobtrusive’ — and that’s exactly the problem. When the vendor can push its own messages through the same channel the agent uses to serve you, the fundamental assumption that it works solely on your behalf is broken. In automated pipelines, this isn’t just annoying. It’s a first-party prompt injection that undermines output determinism.
