rye-universal-checkout

The provided skill documentation describes legitimate use of Rye's official checkout APIs and SDKs; there is no direct evidence in this file of obfuscation, hidden backdoors, or network exfiltration to unknown domains. The primary security concerns are operational: (1) autonomous single-step purchases enable real-world financial side effects without explicit per-transaction human approval, (2) handling of high-value credentials (API keys, payment tokens) in agent environments risks leakage if not properly protected, and (3) accepting arbitrary external product URLs increases exposure to deceptive inputs that could trigger unintended purchases. Recommendations: enforce explicit user confirmation for real-money single-step flows, restrict and rotate API keys and use least-privilege tokens, avoid logging secrets, validate product metadata and merchant domain before charging, and require audit logging for all purchase actions.
