AI Security Review
scanned 11h ago · by lpm-firewall-aiThe postinstall event is sent only when telemetry consent is already recorded, and its payload is limited to package and runtime metadata plus an anonymous ID. Credential-bearing requests and local server startup are tied to the CLI's service and map features.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Postinstall analytics requires telemetry: true in ~/.extenshi/config.json; service requests and build-map startup occur through their respective commands.
Impact
No unauthorized collection, credential disclosure, or unrelated action was identified.
Mechanism
The consent-gated hook sends limited install analytics to PostHog. CLI service calls use the configured Extenshi BFF and API key; the map command starts a local server.
AI rationale
The postinstall event is sent only when telemetry consent is already recorded, and its payload is limited to package and runtime metadata plus an anonymous ID. Credential-bearing requests and local server startup are tied to the CLI's service and map features.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The install hook sends no event unless the existing config records telemetry: true.
- The install event contains the package surface and version, Node version, OS, architecture and anonymous ID.
- Risk and Pay requests send API keys to the configured Extenshi BFF for the requested service operations.
- The map server is launched only by the explicit map command; Pay mutations require --apply.
Evidence against
- The package has a postinstall hook that can send an analytics event.
- The CLI provides commands that use the configured API key to access Extenshi services.
