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 2d ago · by lpm-firewall-ai

Source inspection found a guarded postinstall setup and package-aligned cloud and quota behavior. The flagged runtime code and inspected dependencies did not establish concrete attack behavior.

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; cloud staging, quota checks, and other runtime functions are invoked through Rudder commands or its local board.

Impact

No unconsented collection, credential theft, agent control-surface change, or other concrete attack was established.

Mechanism

The postinstall script skips when opted out or running as root, then calls the helper setup. Reviewed credential reads feed cloud workspace setup or requests to the corresponding service; agent-related code reads local conversation or model data.

AI rationale

Source inspection found a guarded postinstall setup and package-aligned cloud and quota behavior. The flagged runtime code and inspected dependencies did not establish concrete attack behavior.

Decision evidence

public snapshot

AI called this Clean at 94.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The manifest runs a postinstall setup script; the script skips on opt-out or root and sets up the package's Jujutsu workspace helper.
Claude credentials are staged for the package's cloud workspace flow, while Codex quota credentials are sent to the ChatGPT usage endpoint; local account checks compare identity data with the Rudder cloud service.
The agent-related paths read local conversation or model data, or stage Claude credentials for a cloud worker; the local board serves on loopback.
Flagged runtime paths implement project run management, feedback submission, model-backend selection, secret redaction, and user-requested scheduling or updates.
The inspected dependencies expose terminal and WebSocket functionality; no attack behavior was identified in the reviewed source.

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.
