Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Glob Tool Description Is Now Mode-Aware

The Glob tool's long description previously always included the line "When you are doing an open ended search that may require multiple rounds of globbing and grepping, use the Agent tool instead." This line now appears only in default steering mode. In no_nudges or counter_steer modes it is omitted, consistent with those modes suppressing subagent encouragement.

The full Glob description (with the Agent suggestion) is now stored as a separate constant from the abbreviated form, and Tji() selects between them based on the active steering mode.

Evidence

Conditional Glob description selection (search for "use the Agent tool instead" near Glob tool description logic)

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