Feishu

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Feishu connector with broad read/write/delete capability, but its behavior is purpose-aligned and it requires confirmation before state-changing or destructive actions.

Install only if you want Codex to operate your Feishu account through OOMOL. Review prompts carefully before approving write or destructive actions, especially deletions, permission changes, mail sending, approvals, and bulk Base or Sheet updates.

Vague Triggers

High
Confidence
94% confidence
Finding
The description says to use this skill for ANY Feishu request and instead of calling the API directly, which is an overly broad trigger likely to activate on ordinary mentions of Feishu rather than explicit tool-use intent. Because the skill exposes many write and destructive actions, accidental invocation could cause unintended state changes or bypass safer task-specific routing and confirmation logic.
