Why it matters

The brief keeps reporting Langfuse releases because this is where agent failures become visible: per-conversation traces, tool-approval workflows, and eval queues over real traffic. When a marketing agent does something odd on Tuesday, this is how you find out why.

What to try

Point one production workflow at it and trace a single run end to end — then add an eval on the output you already check by hand.
