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

AI Security Review

scanned 3d ago · by lpm-firewall-ai

Source inspection found no install-time attack or unrelated credential transfer. Persistence and package updates are tied to explicit gateway commands, and the runtime findings are consistent with the package’s gateway and CLI functionality.

Static reason

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

Trigger

A user invokes the gateway setup or update command; no package install lifecycle hook triggers these actions.

Impact

These operations provide expected setup, update, and gateway functionality; inspected source does not establish unauthorized data transfer or account changes.

Mechanism

Setup writes and loads a user-level service, while update runs npm to install this package. Runtime calls support message delivery, MCP configuration, and project utilities.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 91.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json declares build-time publishing and Husky preparation hooks, with no install hook.
The gateway writes and loads a user-level service only through its explicit setup command.
Inspected runtime hints resolve to MCP configuration, message delivery, notifications, scheduled turns, and content or project utilities; they do not establish an unrelated automated account action.
The updater installs this package through the gateway update flow, which presents an interactive confirmation; the widget changelog request uses the current page origin.

Evidence against

The package can install a user-level service and run an npm update when the corresponding gateway commands are invoked.
Runtime functionality launches local model CLIs and delivers messages through gateway adapters.
