ryugi-artifacts@1.21.0

Server and viewer for the Ryugi artifacts app

AI Security Review

scanned 18h ago · by lpm-firewall-ai

The inspected source supports an application package with a user-invoked CLI and bundled viewer components. Scanner similarity and Unicode hints did not establish malicious behavior in the reviewed files.

Static reason

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

Trigger

A user invokes the ryugi-artifacts CLI or opens its viewer.

Impact

No confirmed unauthorized data transfer or other attack impact was established.

Mechanism

The CLI starts the application server and records detected agent markers in local project state; a cloud-link request is conditional on an artifact, Claude Code, and the running server URL.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 89.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json exposes a CLI and has no preinstall, install, or postinstall hook; its prepublishOnly script runs the build.
The flagged viewer files contain application imports, diagram modules, localization strings, and KaTeX parsing code; the reported Unicode finding is consistent with localized text.
The CLI records detected agent environment markers in local project state. Its cloud-link request requires a supplied artifact, a Claude Code environment, and a server URL from the running application.

Evidence against

The inspected source did not show credential harvesting, automatic installation-time execution, or an unrequested account action.
