Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple local fee calculator and compliance keyword checker with no evidence of hidden network, persistence, credential, or destructive behavior.

This appears safe for local fee and marketing-copy screening, but users should treat its outputs as an aid only, not investment or legal advice. Review the calculator assumptions and be aware that the tool metadata lists broad allowed tools even though the inspected workflow does not use them.

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

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 94% confidence
Finding: This file contains natural-language instructions that effectively force a specific language/locale for use of the skill. The policy allows locale constraints only when user opt-in is offered or the restriction is clearly documented and justified as region-specific, which is not present here.
