What

When other machines are attached to a session, Claude gets instructions on how to use them. In some cases these now say the tool for running commands on a machine can be called from inside the REPL, an interactive area where Claude runs code, and that workers can act on a named machine either there or as tools. Before, the instructions said not to call it there.

Why

This changes how Claude may choose to reach attached machines.
