@luckydraw/cumulus@1.0.32

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 package-aligned gateway and agent functionality, interactive service setup, and ordinary build hooks. The scanner’s persistence and execution signals did not establish an unconsented attack.

Static reason

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

Trigger

An operator runs the gateway setup command; service auto-start setup is offered when the command has an interactive terminal.

Impact

The inspected behavior supports gateway operation and optional operator-configured auto-start; no confirmed unauthorized data transfer, persistence, or account action was established.

Mechanism

The package writes gateway configuration and can install a platform service after prompting. Its manifest’s prepare hook runs Husky; prepublishOnly runs build and type checking.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 93.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The manifest’s prepare hook runs Husky, and prepublishOnly runs build and type checking; no install-time payload or consumer policy mutation is shown.
The flagged project setup reaches auto-start service installation through an interactive TTY prompt.
Gateway and agent runtime operations are message handling, context processing, and configured MCP setup; the account-action callers deliver requested or scheduled agent turns.
The flagged subprocess hook manages the Claude process for a user message.
The version check queries the npm registry for package release information.
The gateway widget is a packaged web-chat asset, and the Mermaid bundle identifies itself as a vendored library.
