AI Security Review
scanned 28d ago · by lpm-firewall-aiThe inspected network activity is consistent with the package's client API functionality, and the manifest has no automatic install hook beyond prepublishOnly. The scanner's callback and secret-pattern hints were not substantiated as malicious behavior by the inspected source.
Static reason
One or more suspicious static signals were detected.
Trigger
Client code invokes the package's flow, session, or event APIs.
Impact
No concrete malicious effect or unrelated credential recipient was established from the inspected excerpts.
Mechanism
The inspected requests send flow/session data or events using fetch; the session request omits browser credentials.
AI rationale
The inspected network activity is consistent with the package's client API functionality, and the manifest has no automatic install hook beyond prepublishOnly. The scanner's callback and secret-pattern hints were not substantiated as malicious behavior by the inspected source.

Decision evidence
public snapshotAI called this Clean at 87.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The package exports its bundled entrypoints through dist/index.cjs and dist/index.js.
- The only install-related lifecycle script is prepublishOnly, which runs a build.
- The inspected requests send flow data and session configuration through package API calls, with credentials omitted.
- An event request uses a bearer token and posts events to its configured URL; the inspected excerpt does not establish an unrelated recipient.
