Chatwork

Security checks across malware telemetry and agentic risk

Overview

This Chatwork skill is a disclosed OOMOL connector with account read/write abilities, and the risky parts are visible and tied to its purpose.

Install this only if you want an agent to access and modify your Chatwork account through OOMOL. Confirm exact room, message, task, and payload details before approving posts, edits, task changes, or message deletion, and only run the oo CLI installer if you trust OOMOL's installer source.

Vague Triggers

Medium
Confidence
94% confidence
Finding
The description says to use this skill for ANY Chatwork request and whenever a task involves Chatwork, which is overly broad and can cause the agent to invoke the skill on routine mentions or ambiguous requests without sufficient user intent validation. Because this skill includes write and destructive actions, over-triggering increases the chance of unintended data access or state-changing operations in the user's Chatwork account.
