AI-agent CLI for Nansen API analytics, DEX swaps, and cross-chain trading
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package does not show a concrete malicious chain, but its global postinstall can install an AI-agent skill through an external npx command with default acceptance. This warrants a warning under the lifecycle agent-extension policy.
