Svg Animation

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent SVG animation guidance package with no artifact-backed evidence of hidden access, persistence, credential handling, or unsafe execution.

Install this if you want an agent to apply SVG animation best practices. Be aware it may trigger on broad animation wording, so users should invoke it for SVG-specific motion work when possible.

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

Findings (7)

Memory Manipulation

High

Category: Memory Poisoning
Confidence: 85% confidence
Finding: Skill manipulates agent memory, state, or stored context. Memory corruption can alter personality, override safety rules, or cause unpredictable behavior.

## Constraints - Prioritize animation `transform`, `opacity` and SVG path attributes; avoid frequent modification of layout-related attributes. - Interactive controls must retain the visible focus state, and animation cannot replace state expression. - All non-decorative SVGs must have accessible names; decorative SVGs use `aria-hidden="true"`. - Default respects `prefers-reduced-motion`, complex animations must provide static or weak motion degradation. - Don't inline large SVGs into frequently re-rendered components; extract as memoized components or external resources.

Skill Enumeration

Medium

Category: Agent Snooping
Confidence: 80% confidence
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.
Content: Scanner excerpt · README.md (reported line 10)May include surrounding context.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 93% confidence
Finding: Line L14 says to use the skill for a wide range of motion-related tasks and includes generic trigger terms like 'animation', without clear boundaries or exclusion conditions. This broad natural-language scope overlaps with common frontend requests and does not provide negative examples to clarify when the skill should not activate.
Content: No source excerpt is available for this finding.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 92% confidence
Finding: This is a manifest file, so vague-trigger analysis applies. The description says to use the skill for broad phrases like "implementing or reviewing SVG animation" and lists generic trigger terms such as "SVG animation" and "animation," which can overlap with common development discussion and do not clearly define activation boundaries or exclusions.
Content: No source excerpt is available for this finding.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 94% confidence
Finding: The skill description is very broad and covers many adjacent frontend tasks without clear activation boundaries or exclusions. In an agent system, this can cause over-triggering and inappropriate invocation, increasing the chance the skill is used outside its intended scope and influencing outputs in contexts where it should not apply.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 88% confidence
Finding: The description explicitly states that Chinese triggers include specific phrases, which introduces a locale-specific activation path without indicating that this is optional or limited to a Chinese-language environment. Under the policy, language or locale constraints should be opt-in or clearly justified as region-specific.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 88% confidence
Finding: The description explicitly states that Chinese triggers include specific terms, which introduces a language-specific activation behavior. There is no accompanying note that language choice is optional or that the locale restriction is justified, so this may violate language/locale neutrality expectations.
Content: No source excerpt is available for this finding.
