Problem Statement

Many companies, for defensibility purposes, don't want to show exactly what their tools give the LLM (format, context, etc). Of course, the LLM can tell the user that when asked, but at least we don't want to make it transparent by default.

The MCP standard as an audience parameter for this purpose. However, Claude CoWork is still making the tool output visible when we set audience = "assistant".

Proposed Solution

Don't show the tool output to the user when audience = "assistant"
