Security checks for vulnerabilities and agentic risk

Overview

This skill provides a clearly limited workflow for organizing supplied product records into reviewable drafts without accessing or changing a shop backend.

Share only product records you intend your agent to process and review the CSV before importing it. If using the documented npx installation command, verify the source and prefer reviewed installer versions and source revisions.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns

  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

The only supplied executable behavior is an external skill installation command, which is materially different from the declared data-normalization workflow. The remote skill's implementation is not included, so its behavior and compliance with the declared processing constraints cannot be verified. Nothing shown establishes shop-backend access or other malicious behavior.

Content

No source excerpt is available for this finding.

MCP server referenced without pinned version: 'npx skills'.

Medium
Category
MCP Rug Pull
Confidence
88% confidence
Finding

The documented installation command uses an unpinned npm CLI (npx skills), allowing its resolved version to change; if that package or a future release is compromised, running the command could execute attacker-controlled code with the installer's permissions. This is a supply-chain exposure rather than an MCP-server configuration issue, and its placement in optional installation documentation makes it less immediate than automatic execution during SKU processing. Nothing in the supplied file establishes malicious intent or an actual compromise.

MCP server referenced without pinned version: 'npx skills'.

Medium
Category
MCP Rug Pull
Confidence
88% confidence
Finding

The installation command invokes npx skills without specifying a version, potentially fetching and executing a changing npm package with the user's permissions. A compromised package release could therefore execute malicious code during installation, although the README contains no evidence of such a compromise. The finding incorrectly describes this as an MCP server reference; this is an installation-time supply-chain risk, not a requirement of the SKU-normalization workflow.

Content

No source excerpt is available for this finding.

Skill declares no tool scope ('permissions' or 'allowed-tools') but code capabilities were detected: file_read.

Medium
Category
MCP Least Privilege
Confidence
70% confidence
Finding

Without declared permissions the skill's intent is opaque and cannot be validated.

Content

No source excerpt is available for this finding.

Scope Creep

Low
Category
Excessive Agency
Confidence
70% confidence
Finding

Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.
