AI Security Review
scanned 12d ago · by lpm-firewall-aiSource inspection found no install hook or confirmed attack behavior. The scanner’s flagged configuration paths are inert expressions, while the observed telemetry and credential requests align with CLI analytics and Mastra platform authentication.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
The CLI runs when invoked; platform authentication occurs when a platform feature requests a token.
Impact
No malicious effect was established from these behaviors.
Mechanism
Telemetry sends selected command options to PostHog. Platform code verifies credentials with the Mastra platform; the flagged editor configuration paths are not used by a write operation.
AI rationale
Source inspection found no install hook or confirmed attack behavior. The scanner’s flagged configuration paths are inert expressions, while the observed telemetry and credential requests align with CLI analytics and Mastra platform authentication.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json exposes a CLI entrypoint and has no install lifecycle hook.
- The flagged editor configuration paths are standalone path expressions; no write operation uses them.
- Telemetry receives a restricted set of command options, and the CLI sends it to PostHog.
- Mastra credentials are sent to the Mastra platform for token verification during platform authentication.
