@viraatdas/rudder@2.16.1

A TUI for managing coding agents: run Claude Code, Codex and opencode side by side, each in its own isolated jj workspace.

AI Security Review

scanned 7d ago · by lpm-firewall-ai

Inspected source shows normal jj installation setup and user-invoked cloud workspace behavior, including credentials needed by the remote agent. The scanner similarity and network hints do not establish malicious behavior in the inspected files.

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

The install hook runs during package installation; cloud credential staging requires invoking a cloud launch or handoff action.

Impact

The inspected behavior supports normal dependency setup and user-selected remote workspace use; no independent attack impact was established.

Mechanism

The hook checks for jj and may invoke brew or cargo. The cloud flow stages Claude credentials into its snapshot and uploads that snapshot to Rudder Cloud.

Decision evidence

public snapshot

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

Evidence for AI clean decision

The manifest runs scripts/postinstall.mjs, whose hook checks for jj and, only if it is missing, attempts a standard brew or cargo installation.
Cloud snapshot code stages Claude credentials for remote workspaces, and the launch flow uploads the snapshot to Rudder Cloud when the user invokes that feature.
Claude conversation discovery is scoped to the current project; Codex model discovery reads a local model cache.
Scheduled improvement is installed through an explicit command; inspected collection and state code read run records and save local state.
The inspected runtime helpers bind the board to loopback, check the Rudder npm release, and provide a user-invoked feedback submission path.
