Feishu Calendar Meeting.Tmp

Security checks across malware telemetry and agentic risk

Overview

The skill appears to use a Feishu user token for its intended API integration, with a credential-handling caution but no evidence of hidden or unrelated behavior.

Install only if you intend the agent to access Feishu on your behalf. Store the token in the platform secret mechanism where possible, keep it narrowly scoped, rotate it if exposed, and do not let the agent print or persist the token in chat, logs, or workspace files.

Missing User Warnings

Medium
Confidence
91% confidence
Finding
The skill explicitly instructs reading a persistent user access token from a local file and using it in API calls, but it provides no warning about sensitive credential handling, storage protection, or redaction. In an agent setting, this increases the risk of secret exposure through logs, prompt leakage, unintended file access, or reuse beyond the user's intended scope.
