skykoi@2026.3.547

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

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The package contains substantial surveillance-like and autonomous-agent functionality, but source inspection shows it is disabled by default and activated through its own capture policy rather than silently at npm install. Treat as a dangerous capability requiring a warning, not a confirmed malicious package.

Static reason

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

Trigger

User runs the SkyKoi gateway/capture service after enabling a capture policy.

Impact

Sensitive screen, audio, terminal, message, and filesystem context may reach configured model services; model-driven events may trigger agent work.

Mechanism

Policy-gated local capture, remote model evaluation, and proactive agent dispatch.

Decision evidence

public snapshot

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

Evidence for warning

dist/capture-service-CLn4yEAJ.js starts capture modules for terminal, files, browser, calendar, screen, notifications, messages, and audio.
dist/proactive-eval-B0sSbQ6_.js assembles captured screen/audio/terminal context and posts it to model endpoints.
The proactive loop can invoke gateway chat.send, creating agent turns from captured events.
dist/capture-service-CLn4yEAJ.js starts the proactive loop after capture service activation.

Evidence against

package.json has no preinstall, install, or postinstall hook.
dist/capture-policy-8RA9vGYq.js is deny-by-default; capture requires enabled state, purpose, and selected sources.
Raw input requires the explicit I_UNDERSTAND_RAW_INPUT_CAPTURE acknowledgement.
Observed eval/new Function usages are bundled dependency/WASM compatibility code, not remote-response execution.
