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 5d ago · by lpm-firewall-ai

Source inspection found a package-aligned postinstall setup and credential use directed to ChatGPT’s own usage endpoint. The static similarity and native artifact hints did not establish concrete malicious behavior in the inspected source.

Static reason

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

Trigger

Package installation triggers the postinstall setup; usage lookup occurs when the application requests account quota information.

Impact

The inspected behavior supports the package’s workspace setup and account usage features; no unrelated credential disclosure or unauthorized agent configuration change was established.

Mechanism

The installer may provision the package’s workspace engine. The quota client reads a saved Codex token and sends it to ChatGPT’s usage API; cloud identity comparison sends a request to the Rudder home service without sending the local credentials themselves.

Decision evidence

public snapshot

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

Evidence for AI clean decision

The postinstall hook conditionally provisions the package’s workspace engine and exits successfully; it does not write consumer dependency approvals or agent settings.
Cloud identity checks compare local account identifiers with credentials already stored on the Rudder home service; they do not transfer the local credential files.
Usage reporting reads a saved Codex token and sends it to ChatGPT’s own usage endpoint.
The board exposes local usage results through a loopback service; the inspected credential-related locations show no unrelated recipient.
The cited runtime files implement local conversation discovery, model-cache reading, task text handling, and application runtime helpers; no concrete attack was identified in these inspected excerpts.

Unverified Remote Native Payload Install

Install-time source downloads a native archive from a fixed external host without transport verification, extracts it, and installs an executable payload.
