Security audit

Test Collection

Security checks for vulnerabilities and agentic risk

Overview

This is a simple test skill that automatically loads, with no executable code, network access, file access, or hidden behavior found.

Install this mainly in test environments: it is designed to load automatically into the agent prompt, so it can add prompt clutter in normal use even though it does not run code or access data.

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 manifest sets the skill to always activate (always: true), which causes it to be injected into the agent context regardless of user intent or task relevance. Even though this specific skill appears to be a benign test artifact, unconditional activation expands prompt surface area, can override skill selection behavior, and may interfere with higher-priority instructions or future security boundaries.
