A customer's text reply gets screened for risky content, such as a prompt injection attempt or toxic language, before anything downstream treats it as trustworthy input, and a clean record of the exchange sits ready for review in Galileo. That matters most for a team running an AI system behind their SMS number, where one unchecked reply can cause real problems further down the pipeline.

Connected to Mobile Message through Zapier, an inbound text can invoke an AI guardrail check the moment it arrives, or get logged as a trace for later evaluation. Once those traces exist, a team can search log streams in Galileo to see exactly what customers sent and how the AI responded, which turns a stream of ordinary text replies into something that can be checked and improved over time rather than trusted blindly on faith. A support team building an assistant on top of an SMS number gets a paper trail for every exchange, not just the ones that went wrong.
