Overview

This skill is a straightforward Feishu Sheets integration that can read, edit, create, and delete spreadsheet content when given Feishu credentials.

Install only if you want an agent to manage Feishu Sheets. Use a dedicated Feishu app with narrow Sheets/Drive permissions, avoid admin or tenant-wide credentials, and require explicit human confirmation before deleting worksheets, deleting rows or columns, or overwriting large ranges.

Missing User Warnings

Medium

• Confidence: 84% confidence
• Finding: The skill exposes destructive operations such as delete_sheet and delete_dimension without any warning, confirmation guidance, or mention of irreversible data loss. In an agent setting, this increases the chance of accidental or prompt-induced destructive actions against user spreadsheets, especially when tokens and sheet IDs are easy to extract from URLs.
