Payback

Security checks for vulnerabilities and agentic risk

Overview

This is a simple static reference skill that prints finance-themed text, with some generic mismatched content, but it does not access data, persist, or perform hidden actions.

Install only as a lightweight static reference, not as authoritative financial, accounting, legal, or regulatory advice. Review the generated sections before using them because some content appears generic or mismatched to payback finance analysis.

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 (3)

Intent-Code Divergence

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The top-level description claims the skill is for 'payback in finance contexts,' yet the embedded content includes physical inspection, calibration, startup/shutdown, and equipment-style procedures. This contradiction increases the risk that users or downstream agents will trust the skill for finance advice while receiving irrelevant or potentially harmful instructions, undermining integrity and safe decision-making.
Content: No source excerpt is available for this finding.

Description-Behavior Mismatch

Medium

Category: Not specified by scanner
Confidence: 92% confidence
Finding: The script presents itself as a finance 'payback' reference tool, but substantial sections provide generic operational, equipment, and inspection checklist content that does not fit the stated domain. In an agent skill context, misleading or mismatched reference content can cause the agent to produce unsafe or incorrect guidance, especially in regulated finance workflows where users may rely on the tool as authoritative.
Content: No source excerpt is available for this finding.

Vague Triggers

Low

Category: Not specified by scanner
Confidence: 88% confidence
Finding: The skill's invocation guidance is overly broad and does not define clear limits, prerequisites, or non-goals for use. In a finance-related skill, this can cause an agent to invoke the skill in inappropriate contexts and rely on generic reference material for potentially sensitive or compliance-relevant decisions.
