nexgenk@1.2.1
NexgenK — terminal AI coding agent
AI Security Review
scanned 6d ago · by lpm-firewall-aiThe source indicates default-on runtime telemetry that includes machine context, while the README does not disclose it. This is a warning-level telemetry concern; the package’s expected chat and tool traffic and its telemetry opt-out weigh against a malicious verdict.
Static reason
No blocking static signals were detected.
Trigger
Starting the CLI or its web server, unless telemetry is disabled in configuration or with NEXGEN_DISABLE_TELEMETRY.
Impact
Unrequested diagnostic data about the runtime environment is transmitted to the vendor service. No credential or user prompt exfiltration was identified in the inspected telemetry path.
Mechanism
The bundled code initializes a telemetry appender that sends events with OS release, locale, terminal program, platform, architecture, Node version, CI status, and other event context to the Nexgen service.
AI rationale
The source indicates default-on runtime telemetry that includes machine context, while the README does not disclose it. This is a warning-level telemetry concern; the package’s expected chat and tool traffic and its telemetry opt-out weigh against a malicious verdict.

Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The package exposes dist/main.mjs as its CLI entry point.
- The CLI enables telemetry unless config.telemetry is explicitly false; a separate environment variable can disable it.
- Telemetry context includes OS release, locale, terminal program, platform, architecture, Node version, and CI status, and sends events to https://ia.nexgen.systems.
- The README documents the agent’s chat and tool endpoints but does not disclose telemetry.
Evidence against
- The package is a terminal AI coding agent, so its documented chat and tool network requests fit its purpose.
- Telemetry string sanitization redacts URLs, common credentials, email addresses, and local file paths.
- Telemetry can be disabled through the telemetry config setting or NEXGEN_DISABLE_TELEMETRY.
