@viraatdas/rudder@3.1.7

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 source inspected supports ordinary product behavior: the postinstall hook installs a required tool, and the examined saved-token request goes to the intended service. Static similarity and network hints did not establish malicious behavior.

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

Package installation activates the postinstall hook; usage and cloud features run when invoked.

Impact

No confirmed attack surface was established from the inspected behavior.

Mechanism

The hook checks for Jujutsu and may invoke a platform package manager or Cargo. The inspected Codex usage flow sends its saved token to chatgpt.com.

Decision evidence

public snapshot

AI called this Clean at 79.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json runs a postinstall script that checks for Jujutsu and may install it through the platform package manager or Cargo; the script does not modify agent settings or disclose data.
dist/usage.js reads the saved Codex access token to request usage from chatgpt.com; the inspected cloud credential checks compare local identities with the Rudder cloud account.
dist/cloud.js stages Claude credentials for a cloud workspace; dist/handoff.js and dist/models.js read Claude conversation and Codex model data for product features.
dist/board/daemon.js serves local usage data and includes loopback host checks; dist/util.js and dist/improve/state.js contain local helper and state handling.
The inspected improvement, update-check, feedback, task-summary, and CLI entrypoint excerpts show product functions; no concrete attack behavior was established.

Evidence against

The manifest has a postinstall hook, but its inspected behavior is limited to checking for Jujutsu and attempting an ordinary dependency installation.
The Codex credential request uses the intended chatgpt.com usage endpoint; no transfer to an unrelated recipient was found in the inspected excerpts.
