@viraatdas/rudder@3.1.16

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 6d ago · by lpm-firewall-ai

The postinstall behavior is limited to setting up the package’s stated jj dependency. The credential paths inspected use the Codex token with its usage service or compare local identities through the Rudder cloud API; no concrete attack was established.

Static reason

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

Trigger

The postinstall hook runs after installation; quota retrieval occurs when the application requests quota data.

Impact

The inspected flows did not establish unconsented credential disclosure or harmful system changes.

Mechanism

The hook checks for and installs the stated Jujutsu tool. Quota retrieval sends the saved Codex token to the Codex usage service, while cloud parity compares local identity information with the Rudder cloud account.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 88.0% confidence as Benign with high false-positive risk.

Evidence for AI clean decision

The postinstall hook checks for jj and, if needed, installs the Jujutsu tool through Homebrew or Cargo.
Codex quota code reads the saved access token and sends it to chatgpt.com for the Codex usage endpoint; the caller requests quota data.
Cloud credential parity reads the Codex identity email and compares local identities with the Rudder cloud account through its API.
The inspected agent-related paths read local Claude and Codex data; task summaries redact secret-like tokens, and the board listens on loopback.
The remaining cited runtime excerpts cover scheduling, collection, backend handling, update checks, and feedback behavior; no concrete attack was established.

Evidence against

The scanner similarity labels and parser limits do not establish malicious behavior in the inspected source.
