Agent Web Search Setup

A model backend that cannot search is not the same as a model that searched and found nothing, but from inside the conversation the two look identical. This skill turns the first into the second, on whichever agent is in front of you.

What actually breaks

Anthropic's web_search and web_fetch are server tools: the API runs them during the request and splices results into the same response. OpenAI's Responses API web_search works the same way. The client only ever declares the tool.

A reseller that proxies to another cloud cannot execute those. Anthropic's own documentation states that web fetch is unavailable on Amazon Bedrock and Google Cloud; search was measured failing the same way on both. What comes back is not an error. It is an empty shell, so the model concludes the topic does not exist and says so with total confidence. That is the whole bug, and it is why users report their agent has "gotten stupid" rather than reporting a broken tool.
