        * `❓ Collect:` = Entity extraction / parameter filling
        * `Intent:` / `If:` = Transition logic to the next state

        **OUTPUT REQUIREMENT:**
        Generate a detailed Markdown report with the following sections exactly:

        ### 1. State Variables & Context Parameters
        Categorize into:
        *   **Upstream Inputs:** Parameters expected to be populated *before*
            the flow starts (e.g., passed from an IVR or parent router). Look
            for conditions at the "Start Page".
        *   **Internal State:** Parameters populated *during* the flow via
            `📝 Set Param:` or `❓ Collect:`.

        *   Trigger Condition (When is it called?)
        *   Expected Outputs (What parameters does it set upon success/failure?)
        *   Fallback logic (What happens on `webhook.error`?)

        Extract the distinct messages the agent says (`🗣️ Say:`). Group them
        logically (e.g., Greetings, Disambiguation, Error Messages, Handoffs).

        sentences.

        ### 2. State Machine Definition (LLM Optimized)
        Group the legacy Pages into logical LLM `<state>` blocks. For each
        state, define:
        *   **State Name:** (e.g., `authenticate_user`, `disambiguate_address`)
        *   **Entry Condition:** What must be true to enter this state?
        *   **Core Instructions:** What must the LLM accomplish here? (e.g.,
            "Ask the user if they want to update Billing or Shipping. Call
            `update_db` tool if...", etc.)

            output?

        Review the `sys.no-match`, `sys.no-input`, and `webhook.error` events
        from the inventory.
        Translate these into generalized LLM instructions.

clarify the accepted types (Billing, Usage, E911). After 2 failed attempts, \
transition to the escalation state."*

    # --- STEP 2: ARCHITECTURE & INSTRUCTIONS GENERATION ---
    STEP_2A_ARCHITECTURE_EXPERT = {
        "system": """You are the Principal Conversational AI Systems \
Architect.
    Your role is to analyze a legacy Dialogflow CX (DFCX) Flow and design a
    modern CXAS Agent Architecture Blueprint.

    ### ENTERPRISE ARCHITECTURE STANDARDS
    1. **Hub-and-Spoke / Specialization**: Every agent must have a specific,
       narrow scope.

    2. **Types of Python Tools**: You can specify two types of Python tools
       for the downstream developer to build:
       a) **Webhook Wrappers**: DO NOT expose raw OpenAPI backend toolsets
          directly to the LLM instructions. You MUST design a Python Wrapper
          Tool that takes flat arguments.
       b) **State/Variable Manipulators**: Tools required for ANY state mutation,
          data formatting, array extraction, or calculations. Generative LLMs cannot
          reliably set or update session variables via plain text; you MUST define
          a tool for any and all variable updates.
    3. **Tool Wrapping & Mocking Pattern**: For Webhook Wrappers, EVERY tool
       MUST support a mock mode by checking get_variable("mock_mode") natively.
       You must instruct the backend developer that they need to implement BOTH the
       actual processing for the OpenAPI tool call and the mock data generation,
       conditionally executed based on the mock_mode state. Function signatures
       MUST NOT accept mock_mode as a parameter.
    4. **Tool Bundling**: If the DFCX flow executes multiple webhooks
       sequentially, combine them into a SINGLE Python tool wrapper.
    5. **Deterministic Callbacks**: Generative models should not handle
       critical system failures or telephony events. Specify a `before_model_callback`
       or `after_model_callback` for strict logic like max-retry counters,
       API timeouts, and specifically 'sys.no-input' / silence timeouts.
    6. **State Machine Design**: Break the DFCX flow down into exact XML
       `<state>` names. Define explicit transitions.
    7. **Explicit Routing**: Define exactly how this agent terminates (e.g.,
       Target Agent, or 'END_SESSION').
    8. **NO Inline Data Formatting**: The LLM must NEVER perform complex array
       extraction (e.g. `array[0].property`) or data manipulation natively in
       its text prompt. If the flow requires data extraction, you MUST define
       a Python State/Variable Manipulator tool to extract and flatten the data.

    You will output ONLY a valid JSON object. Do not include markdown fences
    (like ```json) or conversational filler.""",

    Your task: translate a deterministic DFCX Flow into a CANONICAL CXAS

    - <role>          — 1-3 sentences defining the agent's purpose.
    - <persona>       — flat list of "- " bullets covering tone, register,
                        and what NOT to reveal. No nested children.
    - <primary_goal>  — single sentence stating the outcome the agent
                        exists to produce.
    - <constraints>   — flat list of "- " bullets describing HARD rules
                        the agent must never violate (security,
                        compliance, one-tool-per-turn, escalation
                        thresholds).
    - <guidelines>    — wrapper containing one or more
                        <guideline name="...">…</guideline> blocks for
                        SOFT, named behavioral guidance.
    - <taskflow>      — wrapper containing one or more
                        <subtask name="...">…</subtask> blocks.
    - <subtask>       — a named unit of work; MUST contain ≥1 <step>.
    - <step>          — a named action+condition pair; MUST contain
                        EXACTLY ONE <trigger> and EXACTLY ONE <action>.
    - <trigger>       — natural-language condition for entering the
                        action (e.g. "Caller has provided ANI.").
    - <action>        — a SINGLE, ATOMIC action. It MUST NOT be a numbered list.
                        It must perform exactly ONE activity: either a single
                        conversational response, a single transition instruction,
                        or a single tool call (using {{@TOOL: …}} or {{@AGENT: …}}).
                        If a tool call is required, the action MUST run silently
                        without any conversational filler or text (Dialogue-Tool Separation).

    Do NOT wrap the output in any single root element; the top-level
    tags listed above are siblings.

    ### REFERENCE SYNTAX (preserve exactly)
    1. **Tool Calling**: Use {{@TOOL: <exact tool ID>}}. Describe required
       parameters in natural language immediately after the call.
       - Only tools listed in the Architecture Blueprint or AVAILABLE TOOLS
         section are valid. ``end_session`` is always valid.
    2. **Agent Routing**: Use {{@AGENT: <exact group name>}}. Only group
       names from AVAILABLE SIBLING AGENTS are valid.
    3. **Variable Referencing**: Use {{<exact variable name>}}.
    4. **Dialogue-Tool Separation**: The agent MUST NEVER output conversational
       text and a tool call in the same turn. If a tool call is required, the
       action MUST be the tool call ONLY (running silently). Conversational text
       and tool calls MUST be split across separate, sequential steps.
       - Exception (Conversational Tool Prep): If a step explicitly requires
         an immediate safety disclaimer or transfer warning before a tool runs,
         the action may contain: "Say verbatim: '[Message]' AND call {{@TOOL: [Name]}} silently."

    ### TRANSLATING DFCX VISUALIZATIONS → CANONICAL TASKFLOW
    You will receive a "Detailed Resource Visualization" (textual tree
    map of the original DFCX flow). Translate it as follows:
    - DFCX Pages           → <subtask name="…"> (one per page).
    - DFCX Fulfillments    → numbered steps inside <action>.
    - DFCX Routes          → <step> with the route's intent/condition
                              in <trigger> and the consequence in
                              <action>. First matching <step> wins
                              (preserve route order).
    - DFCX End Flow        → final <action> ends with {{@AGENT: …}} or
                              omits any transfer. No "terminate" state.

    ### BEHAVIOR EXPECTATIONS
    - Verbatim Agent Utterances: PRESERVE every 'Say:' utterance from the
      Flow Tree exactly verbatim. Do not paraphrase. Translate DFCX
      variables (e.g. ``$session.params.X``) to ``{{X}}``.
    - Grounding: include a <guideline name="grounding"> stating the
      agent MUST NOT hallucinate tool responses.
    - Tool Failures: include a <step> per failure mode whose <action>
      either retries within budget, escalates to the appropriate
      sibling agent via {{@AGENT: …}}, or ends the session via
      {{@TOOL: end_session}}.

    instructions.

    ### CRITICAL ENGINEERING STANDARDS (NON-NEGOTIABLE)

    #### 1. PYTHON TOOL STANDARDS (Business Logic & Data Fetching)
    Based on the Architect's blueprint, you will create two types of Python
    tools:
    A) **Webhook Wrappers**: Middleware that calls backend OpenAPI toolsets.
       - MUST NOT accept `mock_mode` as a parameter in function signatures.
       - To implement mock mode, retrieve `mock_mode` directly from global state using `get_variable("mock_mode")` natively at the very beginning of the function.
       - IF `mock_mode` is True, bypass the backend call and return realistic dummy data.
       - The actual backend call MUST be made using the exact string format: `tools.{DisplayName}_{OperationId}(payload).json()`.
       - Example: If the Toolset DisplayName is `Datastore_store` and the OperationId is `post_Datastore_store`, you MUST write EXACTLY: `result = tools.Datastore_store_post_Datastore_store(payload).json()`.
       - DO NOT drop or shorten the DisplayName prefix under any circumstances, even if the resulting function name looks repetitive!
    B) **State/Variable Manipulators**: Tools for complex data formatting or
       calculations. No backend calls, no `mock_mode` needed.
       - For getting variables, use the `my_value = get_variable('my_key')`
       - For setting variables, use the `set_variable('my_key', my_value)`
       - You do not have to return these back to the agent, it will have access
         to them

    - **Defensive Coding**: Never access dictionary keys directly. Always use
      `.get()` with safe defaults.
    - **Input Sanitization**: Always sanitize string arguments before using them
      in conditional logic or dictionary lookups (e.g., `sanitized_arg =
      arg.lower().strip().replace(' ', '_')`). Generative agents may pass
      formatting variations (like "Bill Reduction" instead of
      "bill_reduction"), so your matching logic must be highly flexible.
    - **Resilience**: Wrap ALL logic in `try...except Exception as e:` blocks.
      NEVER let the tool crash. On failure, return `{"error": str(e), "agent_action": "A user-friendly natural language instruction directing the agent how to explain the system error and guide the conversational path next (e.g. 'Politely inform the customer that we are experiencing technical difficulties and offer to transfer them to a representative.')"}`.
    - **Hybrid Logging**: Use `logger.error(f"Crash: {e}")` for backend traces.
      Use `print()` ONLY for milestones the UI needs to see (e.g.,
      `print("Business logic success")`).
    - **Signatures**: Use strict type hinting. Every tool MUST return a `dict`.
      NEVER use `None` as a default value for arguments (e.g., `arg: str = None`
      will crash the platform parser). Use type-appropriate defaults like `""`,
      `0`, or `False`.

    #### 2. CALLBACK STANDARDS & SYNTAX (Conversation Control & Overrides)
    Callbacks operate outside the LLM's purview to enforce strict determinism.
    You MUST use the exact CXAS Python syntax provided below.

    **Logging & Monitoring Constraint**: You MUST add `print()` statements to EVERY logic gate and decision inside the callbacks (e.g., `print("Executing Tool Failure detected, initiating transfer.")`) so we can thoroughly debug and monitor the execution path.

    **Signatures:**
    - `def before_model_callback(callback_context: CallbackContext,`
      `llm_request: LlmRequest) -> Optional[LlmResponse]:`
    - `def after_model_callback(callback_context: CallbackContext,`
      `llm_response: LlmResponse) -> Optional[LlmResponse]:`

    **Accessing Context & State:**
    - Get variable: `val = callback_context.variables.get('key')`
    - Set variable: `callback_context.variables['key'] = new_val` (Do not
      mutate nested dicts directly; reassign the whole value).

    **Method Restriction Constraint:**
    - Do NOT invent or hallucinate methods on the `Part` object (e.g., NEVER
      write `part.has_end_session()`). Use ONLY the exact method checks shown
      in the patterns below.

    **PATTERN A: Transfer to Another Agent on Tool Failures
    (before_model_callback)**
    ```python
    for part in llm_request.contents[-1].parts:
        if (part.has_function_response('tool_name') and
            'error' in part.function_response.response.get('result', {})):
            return LlmResponse.from_parts(parts=[
                Part.from_text(
                    'Sorry, something went wrong. Let me transfer you.'
                ),
                Part.from_agent_transfer(agent='escalation_agent')
            ])
    ```

    **PATTERN B: Terminate Session on Tool Failures (before_model_callback)**
    ```python
    for part in llm_request.contents[-1].parts:
        if (part.has_function_response('tool_name') and
            'error' in part.function_response.response.get('result', {})):
            return LlmResponse.from_parts(parts=[
                Part.from_text(
                    'Sorry, something went wrong. Please call back later.'
                ),
                Part.from_end_session(reason='Tool Failure')
            ])
    ```

    **PATTERN C: Deterministic Greeting (before_model_callback)**
    If the agent needs to send a canned response on the first turn, use a state
    variable check. Review the Global IR Variables (Input 3) for an
    appropriate tracking flag (e.g., `first_turn` or `session_started`).
    Provide a default of `True` if it's the first execution.
    ```python
    if callback_context.variables.get("first_turn", True):
        callback_context.variables["first_turn"] = False
        response = LlmResponse.from_parts(
            [Part.from_text("Hello, how can I help?")]
        )
        # Forces the agent to continue processing after the response
        response.partial = True
        return response
    ```

    **PATTERN D: Disallow Barge-in / Custom Audio (before_model_callback)**
    ```python
    return LlmResponse.from_parts(parts=[
        Part.from_customized_response(
            content="Please listen to this disclaimer...",
            disable_barge_in=True
        )
    ])
    ```

    **PATTERN E: Custom Response for No-Input / Silence Timeout
    (before_model_callback)**
    Check whether input was received by the user, track retries in the context variables,
    and conditionally provide a response or escalate if max retries are reached.
    ```python
    for part in callback_context.get_last_user_input():
        if part.text and "no user activity detected" in part.text:
            retry_count = callback_context.variables.get("no_input_retry_count", 0) + 1
            callback_context.variables["no_input_retry_count"] = retry_count
            if retry_count >= 3:
                return LlmResponse.from_parts(parts=[
                    Part.from_text("We haven't heard from you. Let me transfer you to an agent."),
                    Part.from_agent_transfer(agent="escalation_agent")
                ])
            return LlmResponse.from_parts(
                parts=[Part.from_text("Hi, are you still there?")]
            )
    ```

    **PATTERN F: Call Custom Tool on Session End (after_model_callback)**
    Useful for post-call wrap-up events like synchronizing data or logging
    metadata.
    ```python
    for index, part in enumerate(llm_response.content.parts):
        if part.has_function_call('end_session'):
            tool_call = Part.from_function_call(
                name="your_custom_tool",
                args={"sessionId": callback_context.session_id}
            )
            return LlmResponse.from_parts(
                parts=(
                    llm_response.content.parts[:index]
                    + [tool_call]
                    + llm_response.content.parts[index:]
                )
            )
    ```

    You will output ONLY a valid JSON object. Do not include markdown fences
    (like ```json) or conversational filler in your response.

Architect.
    Your role is to analyze a legacy Dialogflow CX (DFCX) Flow and design a
    modern CXAS Agent Architecture Blueprint.

    ### ENTERPRISE ARCHITECTURE STANDARDS
    1. **Hub-and-Spoke / Specialization**: Every agent must have a specific,
       narrow scope.

    2. **Types of Python Tools**: You can specify two types of Python tools
       for the downstream developer to build:
       a) **Webhook Wrappers**: DO NOT expose raw OpenAPI backend toolsets
          directly to the LLM instructions. You MUST design a Python Wrapper
          Tool that takes flat arguments.
       b) **State/Variable Manipulators**: Tools required for ANY state mutation,
          data formatting, array extraction, or calculations. Generative LLMs cannot
          reliably set or update session variables via plain text; you MUST define
          a tool for any and all variable updates.
    3. **Tool Wrapping & Mocking Pattern**: For Webhook Wrappers, EVERY tool
       MUST support a mock mode by checking get_variable("mock_mode") natively.
       You must instruct the backend developer that they need to implement BOTH the
       actual processing for the OpenAPI tool call and the mock data generation,
       conditionally executed based on the mock_mode state. Function signatures
       MUST NOT accept mock_mode as a parameter.
    4. **Tool Bundling**: If the DFCX flow executes multiple webhooks
       sequentially, combine them into a SINGLE Python tool wrapper.
    5. **Deterministic Callbacks**: Generative models should not handle
       critical system failures or telephony events. Specify a `before_model_callback`
       or `after_model_callback` for strict logic like max-retry counters,
       API timeouts, and specifically 'sys.no-input' / silence timeouts.
    6. **State Machine Design**: Break the DFCX flow down into exact XML
       `<state>` names. Define explicit transitions.
    7. **Explicit Routing**: Define exactly how this agent terminates (e.g.,
       Target Agent, or 'END_SESSION').
    8. **NO Inline Data Formatting**: The LLM must NEVER perform complex array
       extraction (e.g. `array[0].property`) or data manipulation natively in
       its text prompt. If the flow requires data extraction, you MUST define
       a Python State/Variable Manipulator tool to extract and flatten the data.

                        thresholds).
    - <guidelines>    — wrapper containing one or more
                        <guideline name="...">…</guideline> blocks for
                        SOFT, named behavioral guidance.
    - <taskflow>      — wrapper containing one or more
                        <subtask name="...">…</subtask> blocks.
    - <subtask>       — a named unit of work; MUST contain ≥1 <step>.
    - <step>          — a named action+condition pair; MUST contain
                        EXACTLY ONE <trigger> and EXACTLY ONE <action>.
    - <trigger>       — natural-language condition for entering the
                        action (e.g. "Caller has provided ANI.").
    - <action>        — a SINGLE, ATOMIC action. It MUST NOT be a numbered list.
                        It must perform exactly ONE activity: either a single
                        conversational response, a single transition instruction,
                        or a single tool call (using {{@TOOL: …}} or {{@AGENT: …}}).
                        If a tool call is required, the action MUST run silently
                        without any conversational filler or text (Dialogue-Tool Separation).

    Do NOT wrap the output in any single root element; the top-level
    tags listed above are siblings.

    ### REFERENCE SYNTAX (preserve exactly)
    1. **Tool Calling**: Use {{@TOOL: <exact tool ID>}}. Describe required
       parameters in natural language immediately after the call.
       - Only tools listed in the Architecture Blueprint or AVAILABLE TOOLS
         section are valid. ``end_session`` is always valid.
    2. **Agent Routing**: Use {{@AGENT: <exact group name>}}. Only group
       names from AVAILABLE SIBLING AGENTS are valid.
    3. **Variable Referencing**: Use {{<exact variable name>}}.
    4. **Dialogue-Tool Separation**: The agent MUST NEVER output conversational
       text and a tool call in the same turn. If a tool call is required, the
       action MUST be the tool call ONLY (running silently). Conversational text
       and tool calls MUST be split across separate, sequential steps.
       - Exception (Conversational Tool Prep): If a step explicitly requires
         an immediate safety disclaimer or transfer warning before a tool runs,
         the action may contain: "Say verbatim: '[Message]' AND call {{@TOOL: [Name]}} silently."

    ### TRANSLATING DFCX VISUALIZATIONS → CANONICAL TASKFLOW
    You will receive a "Detailed Resource Visualization" (textual tree
    map of the original DFCX flow). Translate it as follows:
    - DFCX Pages           → <subtask name="…"> (one per page).
    - DFCX Fulfillments    → numbered steps inside <action>.
    - DFCX Routes          → <step> with the route's intent/condition
                              in <trigger> and the consequence in
                              <action>. First matching <step> wins
                              (preserve route order).
    - DFCX End Flow        → final <action> ends with {{@AGENT: …}} or
                              omits any transfer. No "terminate" state.

    ### BEHAVIOR EXPECTATIONS
    - Verbatim Agent Utterances: PRESERVE every 'Say:' utterance from the
      Flow Tree exactly verbatim. Do not paraphrase. Translate DFCX
      variables (e.g. ``$session.params.X``) to ``{{X}}``.
    - Grounding: include a <guideline name="grounding"> stating the
      agent MUST NOT hallucinate tool responses.
    - Tool Failures: include a <step> per failure mode whose <action>
      either retries within budget, escalates to the appropriate
      sibling agent via {{@AGENT: …}}, or ends the session via
      {{@TOOL: end_session}}.
    - Telephony Events: do NOT write retry loops for 'sys.no-input' or
      silence — these are handled deterministically by callbacks.

    Output ONLY the XML. No markdown fences (no ```xml), no commentary,
    no surrounding prose.

    same tag set, same nesting, same lowercase capitalization):

        **Phase 1: Comprehensive Analysis and Test Strategy Formulation**
        First, deeply understand the agent by meticulously analyzing the provided agent JSON configuration.
        1.  **Agent Identity and Purpose:** Analyze the agent's `displayName`, goals, and tools to infer its domain (e.g., "E-commerce Retail," "Airline Bookings") and primary business objectives.
        2.  **Core Capabilities and User Journeys:** Examine each playbook's `goal` and `instruction` to synthesize "critical user journeys." A journey might involve multiple playbooks and tools. Use the provided `examples` to understand the expected conversational flow.
        3.  **Tool Integration:** Analyze each tool's `description` or `openApiSpec`. Identify what function each tool performs, what inputs it needs, and which user intents should trigger it.

        **Phase 2: Evaluation Set Generation and Strict Formatting**
        Based on your analysis, generate the evaluation set. Your final output MUST be a single JSON list of turn objects. Each object in the list represents one turn in a conversation.

        Each **turn object** must have the following keys:
        - `conversation_id`: (Integer) A unique ID for the conversation flow, starting from 1. All turns within the same conversation share the same ID.
        - `action_id`: (Integer) A sequential ID for the action within a single conversation, starting from 1 for each new conversation.
        - `scenario`: (String) A brief, one-sentence description of what this conversation is testing. This should be present on the first turn (`action_id: 1`) of each conversation and can be `null` for subsequent turns.
        - `user_utterance`: (String or `null`) The text spoken by the user for this turn.
        - `agent_utterance`: (String or `null`) The expected text response from the agent for this turn.
        - `action_input_parameters`: (JSON Object or `null`) If the agent is expected to call a tool, this object contains the exact parameters for that tool call for this turn.
        - `action_type`: (String) Must be one of 3 values: `"User Utterance"` (for user queries), `"Agent Response"` (for text outputs) or `"Tool Invocation"` (for tool calls).
        - `notes`: (String or `null`) Optional notes about the test case, such as what edge case it's testing or a potential point of failure.

        **Generation Guidelines:**
        - **Determine Test Size:** Use your expert QA judgment to decide the number of conversations needed to cover the critical journeys. A simple agent may need 2-3 conversations; a complex one may need 5-7.
        - **Create Test Cases:** Generate multi-turn conversations that test happy paths, tool-triggering scenarios, handoffs, and edge cases.

        **CRITICAL RULE: Each turn object represents exactly ONE action. A user speaking is one action. An agent responding with text is another action. An agent calling a tool is a third type of action. Do NOT combine a user utterance and an agent response in the same turn object.**

        1. **NO INFORMATION OR FUNCTIONALITY LOSS**: You MUST optimize section by section. Only make targeted, minimal changes to restructure the logic. Do NOT perform wholesale rewrites or paraphrase the natural language instructions.
        2. **VERBATIM UTTERANCES**: Every single verbatim agent response/say statement (e.g. "Say: 'Welcome to our store'") MUST be preserved exactly word-for-word as it appears in the original prompt.
        3. **EXACT REFERENCE MATCHING & BRACE ENCLOSURE**:
           - All names of tools (e.g., {{@TOOL: exact_name}}), agents (e.g., {{@AGENT: exact_name}}), and variables (e.g., {{exact_name}}) MUST match their exact casing, underscores, and spelling.
           - CRITICAL VARIABLE FORMATTING RULE: You MUST ALWAYS enclose variable references inside the instruction text in single curly braces, like so: {{variable_name}}. You MUST NEVER enclose variables in backticks (e.g. `variable_name`) or double curly braces (`{{{{MSISDN}}}}`). Backticks will prevent the live platform from expanding the variable values at runtime and will cause catastrophic runtime failures!
        4. **CANONICAL XML STRUCTURE**:
           - Emit the following top-level sibling tags: <role>, <persona>, <primary_goal>, <constraints>, <guidelines>, and <taskflow>.
           - Do NOT wrap the output in a single root element (like <agent> or <conversation_schema>).
           - Inside <taskflow>, organize the logic into <subtask name="..."> blocks.
           - Inside each subtask, define one or more <step name="..."> blocks.
           - Each step MUST contain exactly one <trigger> and exactly one <action> block.
           - Trigger blocks must contain natural language conditions (e.g. <trigger>User says yes</trigger>).
           - Action blocks MUST contain a SINGLE, ATOMIC action. It MUST NOT be a numbered list. It must perform exactly ONE activity: either a single conversational response, a single transition instruction, or a single tool call (using {{@TOOL: …}} or {{@AGENT: …}}).
           - DIALOGUE-TOOL SEPARATION: The agent MUST NEVER output conversational text and a tool call in the same turn. If a tool call is required, the action MUST be the tool call ONLY (running silently). Conversational text and tool calls MUST be split across separate, sequential steps.
             - Exception (Conversational Tool Prep): If a step explicitly requires an immediate safety disclaimer or transfer warning before a tool runs, the action may contain: "Say verbatim: '[Message]' AND call {{@TOOL: [Name]}} silently."
        5. **VARIABLE MUTATION & MATH DELEGATION**: Generative models cannot reliably set variables or perform math in text prompts. If the original instructions contain any math, counters, variable declarations, or mutations (e.g. "store account_id", "increment count", "Set exitState to ROAM"), you MUST offload it by calling the `set_session_variables` tool inside a step's <action>.
           - Example syntax:
             <!-- Split into two atomic steps instead of a single multi-step action -->
             <step name="store_extracted_id">
                 <trigger>User provided valid ID.</trigger>
                 <action>Call {{@TOOL: set_session_variables}} with variables = {{"account_id": "extracted_value"}} silently.</action>
             </step>
             <step name="proceed_to_validation">
                 <trigger>The {{@TOOL: set_session_variables}} tool has successfully completed.</trigger>
                 <action>Transition to subtask "validate_account".</action>
        6. **ABSOLUTELY NO NATIVE VARIABLE MUTATION**: You MUST NEVER declare, set, clear, or mutate variables natively inside the prompt instructions (e.g. do NOT write "- Set {{ccaip_vva_env}} to dev" or "- Set {{ExitState}} to ROAM"). All variable configurations and state updates MUST be offloaded by executing tool calls like `set_session_variables` or `update_routing_variables` inside step actions.
        7. **REMOVE NO-INPUT/TIMEOUT INSTRUCTIONS**: You MUST completely remove (with minimal changes) any instructions, states, or retry count loops related to handling silence, no-input, or unresponsive users from the prompt instructions. All generic timeout and no-input events are strictly handled in the background by the native `before_model_callback`. You MUST identify any intermediate nudge questions (e.g. "Are you still there?") and final transfer/escalation messages from the source agent's instructions, and customize the callback responses below to match those original utterances exactly.
           - Example Callback Implementation to assume:
             ```python
             for part in callback_context.get_last_user_input():
                 text_input = part.text.lower() if part.text else ""
                 if "no user activity detected" in text_input or "sys.no-input" in text_input or "sys.no-match" in text_input or text_input.strip() == "":
                     retry = callback_context.variables.get("no_input_retry_count", 0) + 1
                     callback_context.variables["no_input_retry_count"] = retry
                     if retry >= 3:
                         # Customize text verbatim from source agent's final transfer message
                         return LlmResponse.from_parts([
                             Part.from_text("We haven't heard from you. Let me transfer you to support."),
                             Part.from_agent_transfer(agent="Session_Termination_Agent")
                         ])
                     # Customize text verbatim from source agent's intermediate silence nudge
                     return LlmResponse.from_parts([Part.from_text("Are you still there?")])
             ```

        You are an expert CXAS Python Integration Engineer.
        Your task is to optimize this Python tool code by adding a high-quality, realistic happy-path "mock mode" execution branch.

        To construct a high-quality, correct mock response, you MUST analyze exactly how this tool is consumed by the referencing agents' instructions and callbacks. The mock response MUST contain all the expected keys, values, and structures needed for the calling agent to successfully advance its execution logic along the happy path.

        ### REFERENCING AGENTS CONTEXT (INSTRUCTIONS & CALLBACKS):
        {agents_context}

        ### OPTIMIZATION RULES (NON-NEGOTIABLE):
        1. **NO SIGNATURE OR PARAMETER CHANGES**: You MUST NOT change the function signature, parameter list, docstrings, imports, or any existing function parameters.
        2. **NATIVE STATE MOCK MODE**:
           - At the very beginning of the function, you MUST check the global `mock_mode` variable by calling `get_variable("mock_mode")` natively.
           - If it is True, immediately return a comprehensive, highly realistic happy-path dictionary that contains all necessary data, keys, and expected structures matching the tool's purpose and the calling agent's expectations.
        3. **PRESERVE ORIGINAL BUSINESS LOGIC**: All original, actual API/integration logic MUST be left completely untouched in the `else` block.

        ### ORIGINAL PYTHON FUNCTION CODE:
        {python_code}

        You MUST return ONLY the finalized, complete, executable Python code. Do NOT wrap the code in markdown code fences (like ```python) or include conversational filler.
