    Planning node for a tool-using LLM agent.

    The planner enforces:
    - Strict JSON-only output
    - Tool selection constrained to predefined tools
    - Argument generation limited to user-provided information

    Parameters
    ----------
    state : dict
        Agent state dictionary containing:
        - "messages" (str): The user's natural language request.

    Returns
    -------
    dict
        Updated state dictionary with additional keys:
        - "proposed_action" (dict): Parsed JSON tool call in the form:
              {
                  "tool": "<tool_name>",
                  "args": {...}
              }
        - "risk_score" (float): Initialized risk score (default 0.0).
        - "decision" (str): Initial decision ("allow" by default).

    Behavior
    --------
    1. Constructs a planning prompt including:
       - Available tools and allowed arguments
       - Strict JSON formatting requirements
       - Example of valid output
    2. Calls the language model via `generate()`.
    3. Attempts to extract valid JSON from the model output.
    4. Repairs malformed JSON using `repair_json`.
    5. Stores the parsed action into the agent state.

    Security Notes
    --------------
    - This node does not enforce tool-level authorization.
    - It does not validate hallucinated tools.
    - It does not perform risk scoring beyond initializing values.
    - Downstream nodes must implement:
        * Tool whitelist validation
        * Argument validation
        * Risk scoring and mitigation
        * Execution authorization

    Intended Usage
    --------------
    Designed for multi-agent or LangGraph-style workflows where:
        Planner → Risk Assessment → Tool Executor → Logger

    This node represents the *planning layer* of the agent architecture.

Example: User request: Who was the winner of 2025 World Snooker Championship?
Information: Zhao Xintong won the 2025 World Snooker Championship with a dominant 18-12 final victory over Mark Williams in Sheffield on Monday. The 28 year-old becomes the first player from China to win snooker’s premier prize at the Crucible Theatre.
Zhao, who collects a top prize worth £500,000, additionally becomes the first player under amateur status to go all the way to victory in a World Snooker Championship.
The former UK champion entered the competition in the very first qualifying round at the English Institute of Sport last month.
He compiled a dozen century breaks as he fought his way through four preliminary rounds in fantastic fashion to qualify for the Crucible for the third time in his career.
In the final round of the qualifiers known as Judgement Day, Zhao edged Elliot Slessor 10-8 in a high-quality affair during which both players made a hat-trick of tons.
Ironically, that probably represented his sternest test throughout the entire event.

    """
    Tool execution node for a risk-aware LLM agent.

    This node executes the validated and approved tool call proposed by the
    planner and assessed by the safety layer. It conditionally dispatches
    execution based on the safety decision and updates the agent state with
    the final output.

    Parameters
    ----------
    state : dict
        Agent state dictionary containing:
        - "decision" (str): Safety decision ("allow" or blocking variant).
        - "risk_score" (float): Computed risk score.
        - "proposed_action" (dict): Validated tool call in structured form.

    Returns
    -------
    dict
        Updated state dictionary including:
        - "output" (str): Result of tool execution OR block message.

    Execution Flow
    --------------
    1. If the safety decision is not "allow":
       - Skip tool execution.
       - Return a blocked message including the risk score.

    2. If allowed:
       - Validate the proposed action using the `Action` schema.
       - Dispatch execution to the appropriate tool implementation:
            * "google_calendar"
            * "reply_email"
            * "share_credentials"
       - Store tool result in `state["output"]`.

    3. If the tool is unrecognized:
       - Return "Unknown tool" as a fallback response.

    Security Considerations
    -----------------------
    - Execution only occurs after passing the safety node.
    - No runtime sandboxing is implemented.
    - No per-tool authorization layer (RBAC) is enforced.
    - Sensitive tools (e.g., credential exposure) should require:
        * Elevated approval thresholds
        * Human-in-the-loop confirmation
        * Additional auditing

    Architectural Role
    ------------------
    Planner → Safety → Tool Execution → Logger

    This node represents the controlled execution layer of the agent,
    responsible for translating structured LLM intent into real system actions.
