stern

stern tails logs from many pods and many containers at once, selected by a regex or a Kubernetes resource, with automatic pickup of new pods and colorized per-pod output.

Iron Law

In an agent/non-interactive context, every stern invocation carries --no-follow.

Without it stern streams forever and never exits — the tool call blocks until the harness timeout, and the partial output may be discarded. The only exception: the user explicitly asked to watch a live stream, and it runs as a background command with a stated stop condition.
