飞书群聊总结技能。当用户说"总结群聊"、"拉取聊天记录"、"看看这个群说了啥"、"这周说了啥"、"最近咋样"、"最近一个月"、"最近一周"、"帮我看看这几天"等时触发。能识别时间范围（默认7天），拉取消息后生成摘要回复到群里，并创建飞书文档链接。

This skill appears to implement what it claims (fetch Feishu chat messages, summarize, create a doc) but has a few red flags you should address before installing: - Metadata mismatch: the registry does not list the required FEISHU_APP_ID and FEISHU_APP_SECRET even though SKILL.md and the script require them. Consider asking the publisher to correct the metadata so permission/credential prompts are accurate. - Review the 'feishu-docs' CLI dependency: the script calls an external binary via subprocess and passes credentials through the environment. Only install or allow a trusted feishu-docs binary from an official source, and inspect it before use. - Sensitive data at rest: the script writes a temporary markdown file with chat content (tmp_chat_summary.md). Ensure the runtime environment is trusted, and consider modifying the script to securely delete the temp file after upload or to stream the content instead of writing to disk. - Least privilege: create Feishu credentials scoped as narrowly as possible (read-only im:message:readonly and doc create as needed) and rotate them if accidentally exposed. - Test in a safe environment first: run with a small chat and limited date range to confirm behavior and outputs. If you need more assurance, request a full, untruncated copy of the script from the publisher (the provided script was truncated in the listing) and have it reviewed for any hidden network calls or data exfiltration logic. Given the credential handling and subprocess invocation, treat this skill cautiously until you verify the external CLI and fix the metadata mismatch.
