Security checks for vulnerabilities and agentic risk

Overview

The skill creates packing checklists from sanitized orders, and its bundled implementation matches that purpose without accessing business systems.

Provide only sanitized orders and manually verify the checklist before packing. The documented installer is unpinned; prefer reviewed installer and skill 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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The only supplied command performs skill installation, which is materially different from organizing order data into warehouse checklists. The installed skill might implement the described workflow, but its contents are not supplied and cannot be verified from this command.

Content

No source excerpt is available for this finding.

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

Medium
Category
MCP Rug Pull
Confidence
93% confidence
Finding

The documented command invokes the npm package skills without pinning its version, so execution can resolve to a changing release rather than a reviewed artifact. If a resolved release is compromised, running the command could execute attacker-controlled code with the user's permissions; the checklist-only business purpose does not constrain this installer. The finding incorrectly labels this an MCP server reference, but the underlying unpinned executable dependency concern is valid.

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

Medium
Category
MCP Rug Pull
Confidence
88% confidence
Finding

The installation command invokes the unpinned skills npm package through npx, which can download and execute a changing release with the installing user's permissions. A compromised future release could therefore execute malicious code; this is a supply-chain exposure, not an MCP-server reference as the static finding claims. The README shows no malicious intent, and its offline, manual-review purpose does not require this mutable installation dependency.

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, shell.

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.
