Recommended action: Inspect every web_search_tool_result block: if content is an object with type web_search_tool_result_error, branch on error_code (raise max_uses, shorten domain filter lists, back off on too_many_requests) rather than relying on HTTP status.
Option: Detect web_search_tool_result_error blocks in the 200 response [evidence: official_recommended_action]
Applies when: Any client using Anthropic server-side web search
Steps:
1. Iterate response.content for type=='web_search_tool_result'
2. If content is a dict with type 'web_search_tool_result_error', read error_code
3. Handle max_uses_exceeded by raising max_uses or splitting the task; request_too_large by trimming allowed_domains/blocked_domains lists; too_many_requests by backing off
Expected: Search failures become visible instead of silently degrading answers
