Example

Simple approval wrapper

This is a plain Python pattern you can use around the call-result loop you built earlier. The important part is that approval happens before the real tool function runs.

For a hackathon demo, terminal approval is acceptable. In a deployed app, use a stored state so the run can resume after approval.

APPROVAL_REQUIRED = {
    "send_email",
    "create_github_issue",
    "update_database",
    "make_payment"
}

TOOLS = {
    "search_notes": search_notes,
    "send_email": send_email,
    "create_github_issue": create_github_issue,
}

def needs_approval(tool_name):
    return tool_name in APPROVAL_REQUIRED

def ask_for_approval(tool_name, args):
    print("Approval needed")
    print("Tool:", tool_name)
    print("Args:", args)
    choice = input("Type approve or reject: ").strip().lower()
    return choice == "approve"

def execute_tool_call(tool_call):
    tool_name = tool_call["name"]
    args = tool_call["arguments"]

    if needs_approval(tool_name):
        approved = ask_for_approval(tool_name, args)
        if not approved:
            return {
                "ok": False,
                "error": "Human rejected this tool call",
                "tool": tool_name
            }

    result = TOOLS[tool_name](**args)
    return {"ok": True, "result": result}
