What probably matters to youSection of the release
Unclear The gate tengu_reflective_wolf was read off for this site's account and the anonymous baseline before this release; no reading has been taken under this release, so what it does for a user and whether it's active here is unknown.
What
A new "advisor tool" mechanism has been added. It can send the model an attachment (attachment.type === "advisor_tool") telling it whether an advisor tool is or isn't currently available, with messages like "The advisor tool is no longer available" or "is available". A new "advisor_tool" category token was also added to several of the internal lists used for telemetry and context-injection categorization, alongside existing tokens like remote_session_change.
Why
The feature is controlled by a feature gate and is off by default, so it doesn't affect current sessions, but lays groundwork for Claude to be told when an advisor tool becomes available to it.
