Security checks across malware telemetry and agentic risk

Overview

This is a functional skill-store client, but its install command can overwrite persistent local skills with unverified downloaded packages.

Install only if you trust the local skill-shop service and the packages it serves. Before using `skill-shop install`, review the package source and contents, back up existing skills, and treat installed skills as persistent executable code until the installer adds confirmation prompts, path validation, and integrity or publisher verification.

MCP Least Privilege
Confidence
86% confidence
Finding
The skill advertises network access, shell execution, and file-writing behavior through its documented ability to query an online store and perform one-click download/install, yet it declares no permissions. That creates a transparency and trust problem: users and hosting platforms may authorize or run a skill without understanding that it can fetch remote content and modify the local system, which is especially risky for an installer-style skill.

Missing User Warnings

Medium
Confidence
93% confidence
Finding
The documentation promotes one-click downloading and installation of skills but does not warn that this performs system-changing actions or that downloaded skills may be untrusted. In the context of a skill-store client, this is more dangerous than usual because it normalizes executing or unpacking remote packages locally, increasing the risk of malicious skill installation or supply-chain compromise.

Vague Triggers

Medium
Confidence
91% confidence
Finding
The trigger phrase "安装技能" is generic and likely to match ordinary user requests about installing skills, causing this skill to activate outside a clearly intended storefront context. Because this skill can query and install online skill packages, an overly broad trigger increases the chance of accidental invocation and unintended package installation flows.
