DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

ENABLE_TOOL_SEARCH=force now works when set through your settings, not just the shell.

ENABLE_TOOL_SEARCH
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
