Both Bash description builders append an extra section whose supplier returns nothing in this build.

What

Both builders of the Bash tool's description now append an extra optional section, but the helper that supplies it returns nothing in this build, so the prompt is unchanged. It is a placeholder for a description block added later.

Evidence

Executes a given bash command and returns its output.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
