The skill forces non-interactive global installations of unpinned, untrusted packages, creating a critical security vulnerability that allows arbitrary code execution with system-wide privileges.

The instructions encourage installing skills globally ('-g'), which increases the blast radius of a potentially malicious or compromised skill by granting it system-wide access rather than scoping it to the current project.

Unpinned npx package execution — `npx <pkg>` without a version pin pulls latest from npm at runtime (seen 12 times in this file at lines 27, 28, 29, 30, 57, 62, 63, 64, 91, 101, …)

The skill relies on external, user-controllable sources (GitHub repositories) for installation. If an attacker creates a malicious skill, the agent's instructions to 'verify quality' are insufficient to prevent the execution of arbitrary code upon installation.
