skykoi@2026.3.604

SkyKoi â€” Koi runtime. Multi-channel gateway CLI with RPC Koi.

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

Source inspection does not establish malicious install-time behavior or a concrete exfiltration chain. It does establish high-impact AI-agent control capabilities, so warn rather than block.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

User runs and configures the SkyKoi CLI/agent with a paired node or canvas.

Impact

A compromised or unsafe agent session could act on an authorized paired device.

Mechanism

Agent-mediated canvas evaluation and paired-node command execution.

AI rationale

Source inspection does not establish malicious install-time behavior or a concrete exfiltration chain. It does establish high-impact AI-agent control capabilities, so warn rather than block.

Evidence

package.jsonskykoi.mjsdist/index.jsdist/reply-Cz49roj8.js

Decision evidence

public snapshot

AI called this Suspicious at 87.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

Runtime canvas tool forwards caller-supplied JavaScript to a paired node.
Runtime node tool forwards caller-provided argv and environment to system.run.
The package is a multi-channel agent runtime with high-impact local-node capabilities.

Evidence against

No preinstall, install, postinstall, or prepare lifecycle hook is declared.
CLI parsing runs only when dist/index.js is the main module.
Node command execution requires a paired node advertising system.run.
Inspected eval hits are bundled dependency/runtime helpers, not remote-response evaluation.
No concrete credential exfiltration or stealth persistence chain was confirmed.
