Security audit

Teacher Lesson Plans (UK Curriculum)

Security checks for vulnerabilities and agentic risk

Overview

This is a markdown-only teaching assistant skill with no executable behavior, but users should avoid entering unnecessary real pupil details.

Install is reasonable for UK-curriculum teaching support. Before using report comments or SEND tailoring, prefer placeholders or initials and follow your school or organisation's rules for pupil data, especially for minors, SEND, medical, behavioural, or safeguarding information.

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 README explicitly promotes generating personalised student report comments from a student's name, attainment, effort, and observations, which encourages users to input potentially sensitive pupil data without any privacy warning, minimisation guidance, or safeguarding controls. In an education context, this creates a realistic risk of exposing personally identifiable or special-category student information to an AI system in ways that may violate school policy or data protection obligations.

Natural-Language Policy Violations

Confidence
90% confidence
Finding

The description mandates UK National Curriculum-aligned outputs and positions the skill broadly for teachers, but it does not explicitly limit use to UK teachers only or offer users a choice of locale/curriculum. This creates a natural-language locale policy issue because the skill defaults to a specific national framework without user opt-in.

Confidence

Finding

The file states that output follows standard UK teaching formats and references UK curriculum and exam specifications for every response. Because this requirement is unconditional and no alternative locale is offered, it forces a specific locale in natural-language behavior.

Finding

The skill explicitly offers personalised student report comments based on student name, attainment, and effort, which invites processing of identifiable pupil data without any visible privacy, minimisation, or handling guidance. In an education context this can lead users to paste personal or special-category school information into the system, creating GDPR/UK data protection and safeguarding risk if data is retained, logged, or shared inappropriately.

Natural-Language Policy Violations

Confidence

Finding

The listing presents the skill as fixed to UK teacher workflows, curriculum references, and exam-board formats, with no indication that users can choose another locale or educational system. This can be a language/locale policy issue because the skill appears to enforce a specific regional standard rather than offering an explicit locale choice.
