skykoi@2026.3.530

SkyKoi — Koi runtime. Multi-channel gateway CLI with RPC Koi.

AI Security Review

scanned 3mo ago · by lpm-firewall-ai

Scanner claims of remote eval and credential theft are not supported by the inspected code; the eval is bundled dependency compatibility code. The package nevertheless ships a powerful agent gateway, so warn rather than block.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

User runs the skykoi/koi CLI or starts its gateway.

Impact

A configured or exposed gateway could exercise powerful local agent capabilities.

Mechanism

User-invoked agent runtime with command execution, browser control, and optional SSH tunneling.

AI rationale

Evidence

package.jsonskykoi.mjsdist/entry.jsdist/index.jsdist/gateway-cli-B1FDawYB.jsdist/dist-q86J2Uh_.jsdist/login-qr-qGKjDzt6.js

Decision evidence

public snapshot

AI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

CLI runtime includes agent command execution and browser-control components.
Gateway CLI can start SSH tunnels and accepts remote gateway credentials.
Bundled agent dependency can download helper binaries on demand.

Evidence against

package.json has no preinstall, install, or postinstall hook.
skykoi.mjs only enables compile cache then imports the packaged CLI entry.
The flagged eval in dist/login-qr-qGKjDzt6.js is protobuf's obfuscated require fallback, not remote-response execution.
No browser credential-store harvesting or command-output exfiltration chain was confirmed.
