What

Monitor is a tool Claude uses to watch a script and react to what it prints. Its instructions tell Claude: "Your script's stdout is the event stream. Each line becomes a notification. Exit ends the watch." The code that builds these instructions can now add a pointer to the tool for waiting, when asked to.

The stock Monitor description captured under v2.1.323 is the same as the one captured under v2.1.322.

Why

This changes what Claude reads about Monitor in the situations where the extra pointer is added.
