South African Tax Article Generator

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward local article generator for South African tax content, with no evidence of hidden access, persistence, credential use, or exfiltration.

Install only if you need South African SARS/VAT/PAYE article drafts. Review all tax deadlines, penalty rates, and generated legal/compliance statements before publishing, and treat any future WordPress publishing integration as requiring separate credential and posting controls.

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

MCP Least Privilege
Confidence
89% confidence
Finding
The skill declares no explicit tool scope or permissions despite indicating code components that can perform file-writing operations. In agent environments, missing tool restrictions can allow broader-than-intended filesystem access, increasing the risk of unauthorized file creation or modification if the implementation or surrounding runtime is misconfigured.

Natural-Language Policy Violations

Medium
Confidence
89% confidence
Finding
The file repeatedly states that the skill generates South African tax, VAT, and SARS compliance content as a fixed behavior. This imposes a specific regional/legal locale in the skill description without any indication that users can choose another locale or explicitly opt into this constraint.

Natural-Language Policy Violations

Medium
Confidence
89% confidence
Finding
The top-level natural-language description states that the generator produces South African tax compliance articles, which imposes a specific national/legal locale. There is no accompanying language indicating that the skill is region-specific by design, optional for the user, or otherwise constrained to users who want South African content.
