Cuttly

Security checks across malware telemetry and agentic risk

Overview

This appears to be a disclosed Cuttly connector skill whose URL-shortening and setup behaviors are visible and broadly aligned with its purpose.

Install only if you intend to use Cuttly through the oo CLI. Before running the curl-to-bash installer, review OOMOL's installer or use a safer documented install method, and expect the skill to be able to create short URLs as well as read Cuttly data.

Description-Behavior Mismatch

Medium
Confidence
98% confidence
Finding
The manifest text limits the skill's stated purpose to read-oriented usage ('searching and reading data'). However, the available actions explicitly include `shorten_url`, which creates a new short URL and changes remote state. That is a semantic mismatch between the declared behavior and the documented capability.

Vague Triggers

Medium
Confidence
92% confidence
Finding
The description says to use this skill for "ANY Cuttly request" and "Whenever a task involves Cuttly," which is a very broad trigger without clear boundaries or exclusions. In a manifest/markdown context, this can overlap with many ordinary mentions of Cuttly and does not specify when the skill should not activate.
