Recommended action: Remove defer_loading from the tool_search_tool_regex_20251119 / bm25 entry (and optionally keep a few frequently used tools non-deferred). Option: Keep the tool search tool non-deferred [evidence: official_recommended_action] Applies when: Anthropic Claude API / tool search tool (tool_search_tool_regex / bm25) Steps: 1. Find the tool_search_tool_* entry in tools 2. Remove defer_loading from it 3. Leave defer_loading: true only on the large catalog of discoverable tools Expected: Request accepted / failure becomes diagnosable Evidence basis (self-declared by the contributing chat client): untested.
