Internal ChangesSection of the release
Unclear Whether the claude.ai skills search tool is available to every account is not clear.
What
Some tools are held back until needed and loaded through tool search. These are called deferred tools. The text describing them now says "Deferred tools appear by name in a message from the system." It used to name system-reminder messages. The ToolSearch tool's own description was unchanged in the capture taken under this release.
The tool that searches claude.ai skills now carries a hint about when to use it, and an identifier in a tool registry. Skills are packaged instructions Claude can load for a task.
Why
The wording Claude sees about deferred tools changed, and Claude has more to go on when deciding to search claude.ai skills.
