What probably matters to youSection of the release
What
Setting ENABLE_TOOL_SEARCH to force pins tool search to its search-based mode and skips the "standard" fallback that would otherwise apply. The value is now read from the environment Claude Code composes from your settings, not just the raw process environment. The override is refused under HIPAA mode and for non-first-party model providers.
Details
Resolved value force selects the tst tool search mode; any other value leaves the previous resolution in place.
If reading settings fails, the failure is logged and treated as "not forced", so the standard fallback still applies.
Usage
ENABLE_TOOL_SEARCH=force claude
Evidence
isToolSearchForceOverride: settings read failed
