This grocery skill appears purpose-built rather than malicious, but it needs review because it handles reusable Kroger login tokens through a hosted proxy and asks agents to persist them.
Review before installing if you plan to use cart or profile features. Product and store searches are lower risk; account features require Kroger login and expose refresh tokens to the hosted proxy and, per the skill instructions, to agent long-term memory. Prefer self-hosting or local CLI mode with your own Kroger credentials for tighter control, avoid saving refresh tokens in agent memory unless you know how to remove or revoke them, and require confirmation before any cart changes.
