+*** Description
+
+What if we could "scrobble" an agent session? Honestly, this is mostly applicable to
+web searches or quick questions via Gemini or similar web-based agents.
+
+The scrobble should be the tool, so using Gemini is an agent_session scrobble, and the
+associated prompt and any response are stored in the AgentSessionLogData. For this,
+we'd need a way to start a prompt with an AI agent via python libraries like genai.
+
+Then we'd ask a question or a prompt request in the top Scrobble something bar. In
+this case, an entry without a -<letter> prefix would be understood as starting a
+Gemini chat and would send the prompt to Gemini, get a response and return it
+to the browser, starting a new scrobble and storing any response in the log data.
+
+Then the AgentSessionLogData would capture a list of turns: [{"prompt_id": <id>,
+"prompt": "A request prompt", "response": "An agent respones"},
