E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
This document contains explicit, actionable instructions for bypassing protections, tampering payment flows, and abusing verification/rate-limiting mechanisms to commit fraud, privacy violations, and large-scale abuse.
W009: Direct money access capability detected (payment gateways, crypto, banking).
What this means
The skill is specifically designed for direct financial operations, giving the agent the ability to move money or execute financial transactions — such as payment processing, cryptocurrency operations, banking integrations, or market order execution.
Why it was flagged
The skill explicitly targets payment flows and payment providers (mentions Stripe, PayPal, Braintree) and includes concrete, actionable instructions and examples to tamper with payments and post fake payment/webhook confirmations (e.g., modifying amount in /payment/initiate, POSTing to /payment/callback with a fake "success" payload). Those are specific, payment-focused execution capabilities enabling financial impact.
