# Tessary frustration

Frustration is one of Tessary's built-in classifiers. It reads the user's messages and flags the
ones expressing annoyance, anger, or disappointment with the situation or the assistant.

It catches users having a bad time in ways that never show up in error rates: an agent that keeps
misunderstanding, loops, or makes the user repeat themselves. It runs over every trace at negligible
per-event cost. When it fires, the finding goes to triage, and findings ruled real issues become a
case, so a spike of frustrated users over one call site shows up as one investigable unit.
