Unclear The conditions that decide whether this sentence is added are not described.

What

The Bash tool runs shell commands, and its description tells Claude how to use it. Under some conditions, a sentence is now added to the part about run_in_background. It says commands run in the background keep going after the reply ends, while a process the shell detaches itself with nohup or & is usually stopped a few minutes after the reply.

The stock Bash description captured under this release is unchanged from the previous one.

Why

This changes what Claude is told about the Bash tool, which can change how it starts long-running commands.
