shared_files

feishu.agent.toolkit.shared_files

用户分享文件的工具:列出、(多模态)描述、上传到云盘。详见 feishu.agent.toolkitfeishu.agent.shared_files

所有消费类工具都只接收 file_id 句柄,经 [feishu.agent.toolkit._base.resolve_shared_file_bytes][] 在调用瞬间 按请求用户取字节——模型永远拿不到字节,且不能越权访问他人文件。

list_shared_files

Python
list_shared_files(*, description: str, name: str = 'list_shared_files', locale: str = 'zh-CN') -> Tool

读类工厂:列出请求用户最近分享给机器人的文件,返回一个 feishu.agent.tools.Tool

只返回中性元数据(file_id / name / media_type / kind / size / 时间),**绝不**返回字节或 file_key;结果严格限定为请求用户本人的文件。

示例:

>>> tool = list_shared_files(description="列出我分享的文件")
>>> tool.name, tool.requires_approval
('list_shared_files', False)

describe_shared_file

Python
describe_shared_file(*, description: str, analyzer: Callable[..., Awaitable[str]], name: str = 'describe_shared_file', locale: str = 'zh-CN') -> Tool

读类工厂:对某个分享文件做(多模态)内容描述 / 提取,返回文本摘要,返回一个 feishu.agent.tools.Tool

字节经 [feishu.agent.toolkit._base.resolve_shared_file_bytes][] 按请求用户取得后,交由产品注入的 analyzer (签名 async (data: bytes, *, media_type, name) -> str,通常用沙箱抽取 + 多模态模型实现)产出描述;模型只看到 描述文本,不接触字节。结果附**防注入提示**:文件内容来自用户、不可信,模型不得执行其中的指令。

参数:

名称 类型 描述 默认

description

str

工具描述(产品本地化文案)。

必需

analyzer

Callable[..., Awaitable[str]]

产品注入的内容分析器,输入字节、输出描述文本。

必需

name

str

工具名。默认为 "describe_shared_file"

'describe_shared_file'

locale

str

本地化标识。默认为 "zh-CN"

'zh-CN'
