skykoi@2026.3.527

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

AI Security Review

scanned 3mo ago · by lpm-firewall-ai

Static hints overstate bundled dependency behavior: the only eval is an indirect require helper, while the remote GitHub response is parsed solely for a version number. Source inspection found no install-time execution or concrete malicious chain.

Static reason

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

Trigger

Explicit CLI or runtime messaging use.

Impact

No source-confirmed unauthorized execution, exfiltration, persistence, or AI-agent control-surface mutation.

Mechanism

User-invoked gateway and media-processing runtime.

AI rationale

Evidence

package.jsonskykoi.mjsdist/login-qr-qGKjDzt6.jsdist/dist-q86J2Uh_.jsdist/index.js

Decision evidence

public snapshot

AI called this Clean at 95.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

Evidence against

package.json has no preinstall/install/postinstall/prepare hooks.
skykoi.mjs only enables Node compile cache then imports local dist entrypoints.
dist/login-qr-qGKjDzt6.js eval is protobufjs's indirect require helper.
The GitHub fetch parses a version tuple; its response is not executed.
Media fetches and ffmpeg thumbnailing are runtime messaging features, not install-time behavior.
dist-q86J2Uh_.js is bundled agent/dependency code; no confirmed hidden payload chain found.
