What is grok-bridge-rs?

grok-build is a skill that lets the Codex coding agent hand off work to Grok, another AI model, without spawning a messy new background process every time it does so. Instead of scattered, hard to track processes, it runs one shared local program that keeps every Grok session visible, grouped by which Codex conversation started it, and easy to close from a browser panel. That browser panel shows the status of every running session, its recent activity, its terminal output, and its working folder, and lets you stop any of them. Since Grok stays a real interactive terminal underneath, you can also look at what it printed, send it another instruction, or attach directly to its terminal yourself. If several Codex conversations are running Grok work at the same time, each one's sessions stay clearly grouped so you do not lose track of which belongs to which task. There is no artificial limit on how many sessions can run at once, only the limits of your own machine. The tool also includes hooks that report on Grok's activity along with heartbeat checks, which help identify sessions that have silently disconnected so they can be cleaned up. Setting it up requires installing and signing into the Grok command line tool first, then downloading a release archive that already contains ready to run programs for Windows, Linux, and macOS on both Intel and ARM chips, and placing it in your AI agent's skills folder. No Python, no separate server, and no cloud relay service are needed. The project's own WebUI supports thirteen languages and follows your browser's language automatically. It ships prewritten prompts that let Claude Code, Codex, or OpenCode install or update the skill on your behalf, including a checksum verification step before anything is extracted.
