AI Security Review
scanned 6d ago · by lpm-firewall-aiThe suspicious gateway and execution signals resolve to bundled provider and server functionality; the inspected source did not establish a malicious credential redirect or install-time behavior. The manifest has no lifecycle hooks, and the top-level entrypoint directs consumers to explicit subpath imports.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
No install-time trigger is present; gateway requests are part of the gateway provider runtime.
Impact
No malicious effect or unrelated credential transfer was established.
Mechanism
The provider uses a gateway authentication token in requests to its configured base URL, which defaults to the Vercel AI Gateway.
AI rationale
The suspicious gateway and execution signals resolve to bundled provider and server functionality; the inspected source did not establish a malicious credential redirect or install-time behavior. The manifest has no lifecycle hooks, and the top-level entrypoint directs consumers to explicit subpath imports.

Decision evidence
public snapshotAI called this Clean at 82.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest exposes server subpaths and lists build, generation, test, and lint scripts; it contains no install lifecycle script.
- The reviewed runtime files are organized as server handlers, schemas, and bundled modules; their required path excerpts are cited below.
- The gateway helper defaults to Vercel AI Gateway and uses its gateway authentication token for gateway requests. This supports a normal provider client, not a confirmed credential redirect.
- The top-level entrypoint directs consumers to specific subpath imports.
