Tyrpay Buyer Skill

Security checks for vulnerabilities and agentic risk

Overview

This payment workflow skill is coherent, but it asks users to configure raw private keys and install mutable packages without enough safety guidance for wallet-level authority.

Review carefully before installing. Use a dedicated low-value wallet, avoid committing .env files, prefer a hardware wallet/KMS/secret manager where possible, pin dependency versions, and only use trusted storage adapters and registries.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
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

Missing User Warnings

Low

Category: Not specified by scanner
Confidence: 87% confidence
Finding: This markdown file lists private key environment variables such as BUYER_PRIVATE_KEY and ZERO_G_STORAGE_PRIVATE_KEY but does not include any user warning about the sensitivity of these secrets or the risks of storing them in a .env file. Under the markdown-specific missing-warning rule, documentation should warn when behavior or setup could affect user data, privacy, or system integrity.
