Security audit

Ib Dp English B

Security checks for vulnerabilities and agentic risk

Overview

This is a markdown-only IB English B teaching reference skill with no executable behavior, persistence, credential access, or data movement.

Installers should treat this as a low-risk educational reference skill. Reviewers may ask the publisher to tighten the invocation language and clarify response-language expectations, but no security-relevant hidden behavior or overbroad authority was found.

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

Vague Triggers

Medium
Confidence
92% confidence
Finding
The skill description is broadly worded enough to overlap with generic teaching, assessment, feedback, and text-analysis tasks, which can cause the agent to invoke this skill outside a narrowly scoped IB English B context. Over-broad routing increases the chance of unintended activation, irrelevant instruction injection into unrelated workflows, and policy boundary confusion when handling general educational content.

Natural-Language Policy Violations

Low
Confidence
75% confidence
Finding
The skill name and description frame the assistant specifically around 'English B', which implies a fixed language context. There is no language-choice or opt-in language explaining whether responses must be in English or whether multilingual support is available, which may conflict with language/locale flexibility expectations.
