AI Security Review
scanned 6d ago · by lpm-firewall-aiThe manifest has no install hook, and the inspected flagged credential flow sends provider credentials to the corresponding provider for token counting. The scanner’s process-execution matches are server and workspace helpers; no concrete attack behavior was established.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A caller uses the package’s server or attachment token-counting functionality.
Impact
No unrelated credential recipient, persistence, or other confirmed attack effect was established.
Mechanism
Token counting sends the existing provider key and attachment input to that provider’s official endpoint; process helpers run workspace checks or start a requested development server.
AI rationale
The manifest has no install hook, and the inspected flagged credential flow sends provider credentials to the corresponding provider for token counting. The scanner’s process-execution matches are server and workspace helpers; no concrete attack behavior was established.

Decision evidence
public snapshotAI called this Clean at 90.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest exposes library entrypoints and contains no install lifecycle hook.
- The flagged credential flow uses an existing provider key for attachment token counting and sends it to that provider’s official API.
- The flagged child process code is part of workspace checks and server startup helpers.
- The remaining required files are bundled server handlers, schemas, and runtime dependencies.
Evidence against
- No package-controlled credential redirect, persistence, or unrelated recipient was established in the inspected source.
- The scanner’s execution and network matches correspond to server functionality and provider-specific token counting.
