Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly a school teaching-management prompt, but it contains an overreaching rule that gives a named person exclusive control over pausing or continuing the agent.

Review this skill before installing in shared or multi-user environments. Its teaching-management content is coherent, but the Max-only pause rule should be removed or changed so any authorized current-session user can stop, pause, or defer work and platform safety rules remain explicitly higher priority.

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

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 93% confidence
Finding: The instruction mandates using specific terminology by language context and explicitly forbids an alternative English term. This is a natural-language locale/style constraint imposed by the skill without indicating user choice or opt-in, which matches the policy-violation category for language or locale restrictions.
Content: No source excerpt is available for this finding.
