What probably matters to youSection of the release
Claude Code now supports an internal 'advisor' model concept, surfaced through the query context via getAdvisorSetting/advisorModel. When the advisor is active and the session isn't compacting, an internal meta message, Never consult the advisor tool., is injected into forked-agent prompts so sub-agents don't recursively call it. The advisor tool itself only runs when first-party auth is combined with a support flag or a remote experiment.
Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.
