左边日志追踪输出的链接是正常的，右边回复的链接不对

The issue with the agent replying with an incorrect link is due to the tool_icon not being set correctly when the tool_provider_type is "dataset-retrieval". In the code, tool_icon is set to an empty string in this case, which results in the agent not having the correct link to reply with.

Here's the relevant code snippet:

if tool_config.get("tool_provider_type", "") != "dataset-retrieval":
    tool_icon = ToolManager.get_tool_icon(
        tenant_id=app_model.tenant_id,
        provider_type=tool_config.get("tool_provider_type", ""),
        provider_id=tool_config.get("tool_provider", ""),
    )
    if not tool_icon:
        tool_entity = find_agent_tool(tool_name)
        if tool_entity:
            tool_icon = ToolManager.get_tool_icon(
                tenant_id=app_model.tenant_id,
                provider_type=tool_entity.provider_type,
                provider_id=tool_entity.provider_id,
            )
else:
    tool_icon = ""

To address this, you can use the create_link_message method from the Tool class to ensure the correct link is returned. Here is an example of how you can use this method:

def create_link_message(self, link: str, save_as: str = '') -> ToolInvokeMessage:
    """
        create a link message

        :param link: the url of the link
        :return: the link message
    """

By using this method, you can ensure that the correct link is generated and returned by the agent, thus resolving the issue of the agent replying with an incorrect link ^[1][2][3].

看起来是这里解析出错了，我不太确是哪儿的问题，可能是 markdown 那边？

这个不太清楚是哪里错误，其他的工具如果是链接返回，有概率会出现这个情况，这个问题不是必现的

是前端的问题，我看到后台的API消息，回复的消息是正确的，前端显示有问题
