RLM-based CLI chat wrapper for Claude with external history context management

AI Security Review

scanned 3d ago · by lpm-firewall-ai

The scanner flags map to expected build hooks, prompted gateway service setup, and an explicitly invoked self-update operation. Reviewed runtime message and configuration paths did not establish credential theft, unauthorized account changes, or another concrete attack.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

A user runs the gateway setup or package update operation.

Impact

These operations provide expected setup and update behavior; no confirmed malicious effect was established.

Mechanism

Setup can create a login service after an interactive prompt; the update operation installs this package at its supplied version.

Decision evidence

public snapshot

AI called this Clean at 84.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json limits its lifecycle hooks to building and type checking before publish and setting up Husky; neither performs consumer-project mutation on registry install.
Gateway service persistence is reached from the explicit setup command and offered only through an interactive prompt; the service runs the gateway at login.
The npm install command is inside the exported update operation and installs this package at the version passed to that operation.
Inspected runtime paths build MCP configuration and send messages through the configured thread pipeline; the account-action hints are message delivery or configuration plumbing, not independent account changes.
The remaining inspected runtime targets cover project context, thread operations, tool configuration, job output, and UI assets; no concrete attack behavior was identified.
