• The system prompt is fetched from the MCP server (optimizer_basic-default). If unavailable, a default instruction is used.
• build_llm_only_agentspec creates a portable AgentSpec Agent with no tools — pure LLM conversation.
• The session manages conversation state. When chat_history is enabled, turns are appended to persistent history. When disabled, turns are stateless and do not affect history.
• Failed turns are fully rolled back — the user message and any partial response are removed so subsequent turns are not corrupted.
