AI Security Review
scanned 17d ago · by lpm-firewall-aiSource inspection found a version-only preinstall check and project writes guarded by the explicit `init` command. The CLI also has disclosed, configurable usage telemetry; no malicious behavior was established.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Package installation triggers the Node version check; project-file creation requires invoking the `init` command.
Impact
No confirmed attack impact; CLI telemetry is disclosed and configurable.
Mechanism
The install hook compares the Node version and exits if unsupported. The `init` command creates missing project files and leaves existing ones intact.
AI rationale
Source inspection found a version-only preinstall check and project writes guarded by the explicit `init` command. The CLI also has disclosed, configurable usage telemetry; no malicious behavior was established.
Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The preinstall hook only runs a Node version check.
- The project file writes are in the explicitly registered `init` command and preserve existing files.
- The CLI launcher loads the bundled CLI after checking for its Pi peer dependencies.
- CLI telemetry is disclosed, sends usage and error data to the configured PostHog host, and can be disabled with environment settings.
- The inspected sources establish no malicious attack behavior.
