The hint telling Claude where attached files are now names each tool's own text field instead of always saying task_description

What

When files are attached, Claude Code can tell Claude they are in a folder and that it should point to them rather than copy the file's text in. Before, the hint always named a field called task_description. It now names the matching text field of whichever tool, meaning an action Claude can take, it is about.

The hint sits behind a server-side switch that is off unless it is switched on remotely. The switch has read on for this site's account and for an anonymous check since the previous reading.

Why

Because the hint is no longer tied to one tool, file attachments look set to work with more than one tool.

The shipped code defaults this off, and the flag server returned on for the one account this site reads on this version. That is the reading that makes the entry above worth a second look, and it still says nothing about your account.

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.
