@viraatdas/rudder@3.0.1

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

The postinstall behavior is limited to installing the required jj tool when it is absent. Credential staging is tied to user-invoked Rudder Cloud workflows and sends snapshots to the package's cloud service, so the inspected source does not establish malicious exfiltration.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

Package installation checks for jj; cloud snapshot transfer occurs when the user invokes a Rudder Cloud operation.

Impact

No hidden attack was established; cloud workspace use transfers included credentials to Rudder Cloud.

Mechanism

The install hook checks for jj and may invoke brew or cargo to install it. The cloud workflow gathers selected home files and credentials, then sends the snapshot to Rudder Cloud.

Decision evidence

public snapshot

AI called this Clean at 86.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json registers a postinstall hook; the hook checks for jj and attempts to install that prerequisite with brew or cargo only when it is missing.
A Rudder Cloud launch creates and uploads a workspace snapshot to the configured Rudder Cloud endpoint. Snapshot credential inclusion is part of that cloud workflow.
The Claude handoff target reads conversations from the local Claude projects directory, and the Codex model target reads a local model cache.
The board daemon restricts requests to loopback and requires a per-process token for mutations.
Improve collection reads run records and redacts excerpts; scheduled runs require an explicit schedule install command, and the default autonomy setting is propose.
Feedback text is redacted before telemetry submission, and version checks query the Rudder package registry.

Evidence against

Cloud snapshots can include local agent credentials, including credentials read from the macOS Keychain, and send the snapshot to Rudder Cloud.
The default improve settings enable collection unless disabled in configuration.
