/**
|
|
* Browser fallback for the server's `get_info` tool, offered only when the
|
|
* server does not serve one (llama-server without --agent). It tells the model
|
|
* which OS the browser runs on and that there is no local file or shell access,
|
|
* so it does not plan around tools that are not there.
|
|
*
|
|
* @see server_tool_get_info in tools/server/server-tools.cpp - the served variant
|
|
* @see buildBrowserInfoToolDefinition in constants/browser-info.ts - tool schema sent to the LLM
