Steps to reproduce

自定义工具中方法的参数似乎不支持Array[string]

即使在schema中定义了参数type为array,items.type为string.但是工具中仍然会识别为string.
自定义工具的schema:

{
    "platform": {
        "type": "array",
        "items": {
            "type": "string"
        },
        "description": "Platform filter for the search. weibo:微博; weixin:微信公众号; news:新闻媒体; short_video:短视频; blog:博客; forum:论坛"
    }
}

✔️ Expected Behavior

自定义工具的参数类型也应该是 Array[string]
platform: Array[string]

❌ Actual Behavior

但是自定义工具后, 依然是string类型

在后续的工作流编辑时,即使上一步输出了 array[string] 类型结果, 会因为参数类型不同, 无法选择参数.
