Security checks for vulnerabilities and agentic risk

Overview

This is a coherent French work-hours calculator skill with no hidden execution, persistence, or data exfiltration behavior found.

Install this only if you want a French-language assistant for work-time calculations. Treat salary and overtime outputs as estimates, not legal or payroll advice, and verify important payroll decisions against your contract, convention collective, or HR source.

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

Findings (2)

Natural-Language Policy Violations

Medium
Confidence
96% confidence
Finding
The instruction "Répondre en français" mandates a specific language for all responses. Under the policy, forcing a language or locale without user opt-in is a natural-language policy violation unless the constraint is explicitly optional or clearly justified as a region-specific requirement.

Natural-Language Policy Violations

Low
Confidence
92% confidence
Finding
The HTML document declares `lang="fr"`, and the visible interface text throughout the page is French-only. Under the policy rule, forcing a specific language without user opt-in can be a natural-language policy violation when no locale choice or region-specific justification is provided.
