Overview

This Google Pay skill is a disclosed implementation guide with payment-safety guardrails, local notes, and no hidden execution behavior.

Install this skill only for a project where you intend to integrate Google Pay and trust your Google Pay, PSP, and backend accounts. Keep it in test mode until the validation checklist passes, and do not put raw payment tokens, private keys, or PSP secrets into the local notes or chat.

A.I.G

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

SkillSpector

Vulnerability Patterns

• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code

Findings (4)

Autonomous Decision Making

Medium

• Category: Excessive Agency
• Confidence: 80% confidence

Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

md

- CLI tools for diagnostics: `curl`, `jq`
- Access to Google Pay business console and target PSP account

Never ask users to paste private keys, full token payloads, or PSP secrets into chat.

## Data Storage

Sudo/Root Execution

Medium

• Category: Privilege Escalation
• Confidence: 80% confidence

Finding

Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.

chmod 600 ~/google-pay/{memory.md,implementations.md,validation-log.md,incidents.md}

Sudo/Root Execution

## Guardrails

- Never ask the user to expose private keys in chat.
- Never store raw Google Pay token payloads in local notes.
- Never claim production readiness without validation evidence.
