Security audit

Catholic Grounding

Security checks for vulnerabilities and agentic risk

Overview

This is a lightweight Catholic reference and answer-format skill with local-only helper scripts and no evidence of hidden access, persistence, or data exfiltration.

Installers should treat this as a small local Catholic reference pack, not an authoritative or exhaustive theology engine. Review the bundled references for accuracy, and be aware that one prayer helper script may need correction before it works as documented.

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 declared description presents a broad Catholic teaching assistant for doctrinal questions, practice, sacraments, moral theology, and tone guidance. The supplied code, however, is narrowly limited to looking up prayer entries in a local markdown reference file by section header. While prayer snippets are mentioned in the description, this code does not implement the primary described capability of answering Catholicism questions or producing structured catechetical responses. Its actual behavior is a specific content lookup utility, which is materially narrower and different from the declared primary purpose.
