XYT AgentOS — Workent 龙虾桌面 Agent 客户端（xyt-client）

AI Security Review

scanned 20d ago · by lpm-firewall-ai

Automatic background service registration and global helper installation warrant a warning for dangerous lifecycle behavior. The inspected source does not support blocking for malware, credential theft, or foreign agent control mutation.

Static reason

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

Trigger

npm installation; service registration requires an existing global xyt-client command on macOS or Linux.

Impact

The client may persist beyond the installation session, and installation changes global tooling and user PATH configuration.

Mechanism

The postinstall hook invokes service installation, and the service code writes configuration for background operation. The watchdog automatically starts or restarts the client.

AI rationale

Decision evidence

public snapshot

AI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json automatically runs scripts/postinstall.mjs during installation.
The install hook invokes xyt-client service install without a consent prompt when the global command exists on macOS or Linux.
dist/cli.js writes a service property list; the supplied watchdog starts the client again when its process is absent.
The install hook also installs tokscale globally, first using registry.npmmirror.com.

Evidence against

The watchdog monitors and restarts this package's own client, which supports a maintenance purpose.
No runtime self-dependency or concrete credential theft was established.
The inspected agent configuration locations contain obfuscated path handling; they do not establish install-time mutation of foreign agent controls.
