AI Security Review
scanned 26d ago · by lpm-firewall-aiSource inspection found an install-time telemetry hook, but it skips unconsented installs and sends limited adoption metadata. The CLI also asks for consent before recording command telemetry; no malicious behavior was established.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Installing the package; the event is sent only when the consent and environment gates allow it.
Impact
The event reports package version and coarse runtime details with an anonymous install ID; inspected source shows no credential or package-content collection.
Mechanism
The hook reads the package’s telemetry configuration and posts the install event to the configured PostHog host or its default host.
AI rationale
Source inspection found an install-time telemetry hook, but it skips unconsented installs and sends limited adoption metadata. The CLI also asks for consent before recording command telemetry; no malicious behavior was established.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest’s postinstall hook runs the package’s install telemetry script.
- The install ping is gated on previously recorded telemetry consent and skips CI and workspace installs.
- The ping sends package and runtime metadata with an anonymous install ID; the CLI asks for telemetry consent before command events.
