Cache Layer

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple cache-layer workflow guide with no executable code, persistence, credential access, or hidden behavior.

This skill appears safe to install as a guidance aid for cache design and debugging. Users should expect it to suggest a structured workflow when cache-related topics come up, and can decline that workflow if they prefer direct help.

A.I.G

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

Finding

The trigger section says the skill applies when the user mentions caching, cache invalidation, or 'closely related work,' but it does not define what counts as closely related. That ambiguity can cause unintended invocation for adjacent performance or architecture discussions that are not specifically about cache-layer workflows.
