Motion Interaction

Security checks for vulnerabilities and agentic risk

Overview

This skill is a frontend motion-design guide with no executable code, credential handling, persistence, or hidden high-impact behavior.

Install this if you want an agent to apply structured frontend motion, animation-performance, and accessibility guidance. Review the broad trigger description if you prefer skills to activate only on very explicit requests.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Finding

Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.

## Description

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
86% confidence
Finding

The manifest description says to use the skill for broad phrases like 'designing', 'implementing', or 'reviewing' frontend motion topics, and lists generic trigger terms such as 'motion design' and 'interactive effects'. Although it includes some exclusions, the activation scope is still expansive and may cause unintended invocation for ordinary frontend discussions involving animation or effects.

Natural-Language Policy Violations

Confidence
89% confidence
Finding

The description explicitly states that Chinese triggers include several phrases, but it does not indicate that multilingual triggering is optional or limited to a justified locale-specific deployment. This can create a language/locale policy concern because the skill behavior is partially defined around a specific language without user opt-in.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
87% confidence
Finding

The manifest text explicitly states 'Chinese triggers include ...' while the rest of the description is otherwise general-purpose and not documented as region-specific. This creates a locale-specific behavior expectation without an explicit opt-in or justification, which matches the language/locale policy concern.
