AI Security Review

scanned 13d ago · by lpm-firewall-ai

The inspected lifecycle and runtime behaviors align with this CLI’s bundled agent integration, updates, and gateway use. The scanner’s similarity and credential-redirection hints were not substantiated by the reviewed source.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Installation runs the postinstall patch script; gateway proxying occurs when the CLI starts the agent and sends API requests.

Impact

No confirmed harmful effect was established from these behaviors.

Mechanism

The package applies UI compatibility patches to its pi dependencies, writes terminal-agent settings and extensions, and limits proxy requests to the configured gateway API namespace.

Decision evidence

public snapshot

AI called this Clean at 88.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The manifest runs a postinstall script that applies runtime patches to the bundled pi coding agent and TUI dependencies.
The CLI configures a local signing proxy to forward requests through the configured gateway; the proxy restricts requests to the gateway API namespace.
The CLI setup writes pi settings and extensions for its documented terminal-agent integration.
The update checker contacts the npm registry for this package’s latest version.
Similarity and structural scanner hints do not establish harmful behavior in the inspected source.
