Security checks for vulnerabilities and agentic risk

Overview

The skill warrants review because it redirects storyboard preparation into cloud image generation, although each image requires user confirmation.

If you only need storyboard preparation, request a preparation-only version before installing. For generation, explicitly approve the provider, submitted content, and possible charges. Verify the intended CLI version; its executable package and credential-file protections were not verified in this review.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied code contains only an authentication-configuration command and performs no storyboard retrieval. Authentication could support a broader storyboard workflow, but the supplied chunk implements credential setup instead of the declared operation.

Description-Behavior Mismatch

Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

The supplied chunk only sets authentication credentials. Although authentication can support storyboard retrieval, no retrieval operation is present, so the chunk's demonstrated purpose materially differs from the declared purpose. There is no evidence of credential exfiltration.

MCP Tool Poisoning
Confidence
97% confidence
Finding

The only supplied command performs login rather than storyboard retrieval. Although authentication could support a larger pipeline, the supplied chunk provides no connection to storyboard access and implements a materially different operation.

MCP Tool Poisoning
Confidence
96% confidence
Finding

The supplied code performs only a login operation and shows no storyboard-related behavior. Authentication could support a larger workflow, but this chunk does not establish that connection and its sole visible purpose differs from the declared purpose.

The skill mandates live image generation rather than limiting execution to storyboard extraction and pipeline preparation.

Excessive Agency
Confidence
96% confidence
Finding

The mandatory terminal-based image-generation workflow expands a storyboard-to-canvas preparation task into live external API execution, potentially transmitting storyboard content and consuming paid credits. Per-image user confirmation and disclosure of the service endpoints reduce the risk, but the unconditional execution requirement still redirects preparation-only requests into an unnecessary generation workflow.

L172–L175 mandate a terminal-based image-generation workflow rather than the storyboard-information retrieval declared at L004.

Medium
Category
Excessive Agency
Confidence
97% confidence
Finding

These instructions require live CLI image generation even though the core workflow prepares a storyboard pipeline for a canvas. This scope expansion can lead to unnecessary external disclosure of prompts and paid API usage; explicit confirmation before each image mitigates, but does not eliminate, the workflow redirection risk.
