  "title": "Claude Agent SDK: Subagents and Session Store",
  "questions": [
    {
      "stage": "pre",
      "question": "What is the difference between the Anthropic Client SDK and the Claude Agent SDK?",
      "options": [
        "Client SDK is raw Messages API; Agent SDK is the Claude Code harness shape with built-in tools, MCP, hooks, subagents, and session store",
        "Client SDK is paid; Agent SDK is free",
        "Client SDK is for Python only",
        "There is no difference"
      ],
      "correct": 0,
      "explanation": "Client SDK gives you the loop; Agent SDK ships the loop pre-built."
    },
    {
      "stage": "pre",
      "question": "What are the two documented purposes of subagents?",
      "options": [
        "Parallelization and context isolation",
        "Caching and rate limiting",
        "Logging and metrics",
        "Authn and authz"
      ],
      "correct": 0,
      "explanation": "Subagents run independent work concurrently and preserve the orchestrator's context budget by isolating context."
    },
    {
      "stage": "check",
      "question": "Which method is NOT part of the session store surface?",
      "options": [
        "append",
        "load",
        "list_subkeys",
        "compile_prompt"
      ],
      "correct": 3,
      "explanation": "Session store ships append, load, list_sessions, delete, list_subkeys; compile_prompt is not a session API."
    },
    {
      "stage": "check",
      "question": "Which is NOT a Claude Agent SDK lifecycle hook?",
      "options": [
        "PreToolUse",
        "PostToolUse",
        "PreCompact",
        "PreEmbedding"
      ],
      "correct": 3,
      "explanation": "Hooks include PreToolUse, PostToolUse, SessionStart/End, UserPromptSubmit, PreCompact, Stop, Notification. PreEmbedding is not a hook."
    },
    {
      "stage": "check",
      "question": "How does trace context propagate across the agent and CLI subprocess?",
      "options": [
        "Through the file system",
        "Through W3C trace context headers passed into the CLI subprocess",
        "Only via the provider's dashboard",
        "Through environment variables only"
      ],
      "correct": 1,
      "explanation": "OTel spans on the caller propagate into the CLI subprocess via W3C trace context, so the whole multi-process run is one trace."
    },
    {
      "stage": "post",
      "question": "What is subagent over-spawn and when does it happen?",
      "options": [
        "Spawning 100 subagents for 100 tiny tasks where overhead dominates; batch instead",
        "Forgetting to close subagents",
        "Spawning before SessionStart",
        "Spawning more subagents than CPU cores"
      ],
      "correct": 0,
      "explanation": "Subagents have overhead; batch small tasks instead of spawning one each."
    },
    {
      "stage": "post",
      "question": "What does Claude Managed Agents trade off against the self-hosted SDK?",
      "options": [
        "Control for managed infrastructure (long-running async, built-in prompt caching, built-in compaction)",
        "Latency for cost",
        "Tools for memory",
        "Tracing for streaming"
      ],
      "correct": 0,
      "explanation": "Managed Agents is the hosted alternative for long-running async work; less control, less ops surface."
    }
