440The `content` array in a tool result accepts `text`, `image`, `audio`, `resource`, and `resource_link` blocks. You can mix them in the same response. In TypeScript, the SDK saves audio blocks to disk and Claude receives a text block with the saved file path; in Python, the SDK drops audio blocks from the tool result and logs a warning. The SDK converts resource link blocks to a text block containing the link's name, URI, and description.

442Claude receives each resource link block as a text block containing the link's name, URI, and description. In TypeScript, your application also receives the links themselves as [`resourceLinks`](/docs/en/agent-sdk/typescript#sdkmcpresourcelink) on the user message's `tool_use_result`; in Python, the SDK flattens them to text before the CLI sees the result, so the Python [`resourceLinks` key](/docs/en/agent-sdk/python#usermessage) is never produced for in-process tools.
