AI Security Review

scanned 4d ago · by lpm-firewall-ai

Source inspection found no install hook, credential transfer to an unrelated recipient, or agent configuration mutation. The scanner's download and execution hint maps to the user-invoked project pull workflow.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

A user invokes app pull.

Impact

The requested setup can run the downloaded project's install code; no package-triggered attack behavior was established.

Mechanism

The command downloads project files into a project folder, then runs that project's dependency installation and setup.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 94.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json identifies the CLI entrypoint and lists development scripts; it declares no install lifecycle hook.
The app pull command is explicitly invoked. It downloads project files, installs that project's dependencies, and runs its setup.
Saved CLI cookies are selected by the configured dashboard and sent to that same dashboard. The default is Pattern's service; an environment variable can select another dashboard.
The flagged .claude locations are a formatting path and an empty-folder ignore entry; they do not show agent configuration changes.
The other required paths inspected contain UI, state, date, booking, service, access-control, and theme utilities; their inspected excerpts show no attack behavior.
