GetYouTubeTranscript

Security checks for vulnerabilities and agentic risk

Overview

This skill mostly matches its transcript-reading purpose, but its first-time setup tells the agent to install a CLI by executing a remotely fetched script without verification.

Review the OOMOL CLI installation path before installing. Prefer installing oo from an official, verifiable package or guide, and do not let an agent run the remote installer automatically unless you trust OOMOL and are comfortable with system-level setup. After setup, the skill appears limited to GetYouTubeTranscript read/search operations through your connected OOMOL account.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The skill instructs the agent to install software by piping a remotely fetched script directly into a shell (curl ... | bash). This is dangerous because it executes unverified code from the network immediately, creating a supply-chain and remote code execution risk if the endpoint, transport, or hosted script is compromised.

Finding

The description says to use this skill for "ANY GetYouTubeTranscript request" and "Whenever a task involves GetYouTubeTranscript," which is an expansive activation condition rather than a narrowly defined trigger. It does not provide exclusions or negative examples to clarify when the skill should not be invoked.
