grok-dev
v1.1.3
Published
An open-source AI coding agent powered by Grok, built with Bun and OpenTUI.
Maintainers
Readme
There are many coding agents. This is Grok’s.
The rest borrowed from each other. We borrowed from all of them, then wired it to Grok—real-time X search, web search, **grok-code-fast-1** and the full Grok model lineup, sub-agents on by default, remote control via Telegram (pair once, drive the agent from your phone while the CLI runs), and a terminal UI that doesn’t feel like it was assembled in a hurry.
Open source. Terminal-native. Built with Bun and OpenTUI. If you want vibes and velocity, you’re in the right repo.
Community-built and unofficial. This project is not affiliated with or endorsed by xAI, and it is not the official Grok CLI.

Install
npm i -g grok-devThe CLI binary is **grok** (yes, the package name and the command differ—deal with it).
Prerequisites: Node 18+ (for the global install), a Grok API key from x.ai, and a modern terminal emulator for the interactive OpenTUI experience. Headless --prompt mode does not depend on terminal UI support. If you want host desktop automation via the built-in computer sub-agent, also enable Accessibility permission for your terminal app on macOS.
Run it
Interactive (default) — launches the OpenTUI coding agent:
grokSupported terminals
For the most reliable interactive OpenTUI experience, use a modern terminal emulator. We currently document and recommend:
- WezTerm (cross-platform)
- Alacritty (cross-platform)
- Ghostty (macOS and Linux)
- Kitty (macOS and Linux)
Other modern terminals may work, but these are the terminal apps we currently recommend and document for interactive use.
Pick a project directory:
grok -d /path/to/your/repoHeadless — one prompt, then exit (scripts, CI, automation):
grok --prompt "run the test suite and summarize failures"
grok -p "show me package.json" --directory /path/to/project
grok --prompt "refactor X" --max-tool-rounds 30
grok --prompt "summarize the repo state" --format json
grok --prompt "review the repo overnight" --batch-api
grok --verify--batch-api uses xAI's Batch API for lower-cost unattended runs. It is a good
fit for scripts, CI, schedules, and other non-interactive workflows where a
delayed result is fine.
Continue a saved session:
grok --session latest
grok -s <session-id>Works in interactive mode too—same flag.
Structured headless output:
grok --prompt "summarize the repo state" --format json--format json emits a newline-delimited JSON event stream instead of the
default human-readable text output. Events are semantic, step-level records such
as step_start, text, tool_use, step_finish, and error.
Computer sub-agent
Grok ships a built-in **computer** sub-agent backed by [agent-desktop](https://github.com/lahfir/agent-desktop) for host desktop automation on macOS.
Ask for it in natural language, for example:
grok "Use the computer sub-agent to take a screenshot of my host desktop and tell me what is open."
grok "Use the computer sub-agent to launch Google Chrome, snapshot the UI, and tell me which refs correspond to the address bar and tabs."Notes:
- Screenshots are saved under
**.grok/computer/**by default. - The primary workflow is snapshot -> refs -> action -> snapshot using
agent-desktopaccessibility snapshots and stable refs like@e1. computer_screenshotis available for visual confirmation, but the preferred path iscomputer_snapshotplus ref-based actions such ascomputer_click,computer_type, andcomputer_scroll.- macOS requires System Settings → Privacy & Security → Accessibility access for the terminal app running
grok. agent-desktopcurrently targets macOS.- If Bun blocks the native binary download during install, run:
node ./node_modules/agent-desktop/scripts/postinstall.jsScheduling
Schedules let Grok run a headless prompt on a recurring schedule or once. Ask for it in natural language, for example:
Create a schedule named daily-changelog-update that runs every weekday at 9am
and updates CHANGELOG.md from the latest merged commits.Recurring schedules require the background daemon:
grok daemon --backgroundUse /schedule in the TUI to browse saved schedules. One-time schedules start
immediately in the background; recurring schedules keep running as long as the
daemon is active.
List Grok models and pricing hints:
grok modelsPass an opening message without another prompt:
grok fix the flaky test in src/foo.test.tsGenerate images or short videos from chat:
grok "Generate a retro-futuristic logo for my CLI called Grok Forge"
grok "Edit ./assets/hero.png into a watercolor poster"
grok "Animate ./assets/cover.jpg into a 6 second cinematic push-in"Image and video generation are exposed as agent tools inside normal chat sessions.
You keep using a text model for the session, and Grok saves generated media under
.grok/generated-media/ by default unless you ask for a specific output path.
What you actually get
| Thing | What it means |
| --------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Grok-native | Defaults tuned for Grok; models like **grok-code-fast-1, **grok-4-1-fast-reasoning**, **grok-4.20-multi-agent-0309**, plus flagship and fast variants—run grok models for the full menu. |
| X + web search | **search_x and **search_web** tools—live posts and docs without pretending the internet stopped in 2023. |
| Media generation | Built-in **generate_image** and **generate_video** tools for text-to-image, image editing, text-to-video, and image-to-video flows. Generated files are saved locally so you can reuse them after the xAI URLs expire. |
| Sub-agents (default behavior) | Foreground **task** delegation (e.g. explore, general, or computer) plus background **delegate** for read-only deep dives—parallelize like you mean it. |
| Verify | **/verify** or **--verify** — inspects your app, builds, tests, boots it, and runs browser smoke checks in a sandboxed environment. Screenshots and video included. |
| Computer use | Built-in **computer** sub-agent for host desktop automation via **agent-desktop**. It prefers semantic accessibility snapshots and stable refs, with screenshots saved under **.grok/computer/** when requested. |
| Custom sub-agents | Define named agents with **subAgents** in **~/.grok/user-settings.json** and manage them from the TUI with **/agents**. |
| Remote control | Pair Telegram from the TUI (/remote-control → Telegram): DM your bot, **/pair, approve the code in-terminal. Keep the CLI running while you ping it from your phone. |
| No “mystery meat” UI | OpenTUI React terminal UI—fast, keyboard-driven, not whatever glitchy thing you’re thinking of. |
| Skills | Agent Skills under **.agents/skills/<name>/SKILL.md (project) or **~/.agents/skills/** (user). Use **/skills** in the TUI to list what’s installed. |
| MCPs | Extend with Model Context Protocol servers—configure via **/mcps** in the TUI or **.grok/settings.json** (mcpServers). |
| Sessions | Conversations persist; **--session latest** picks up where you left off. |
| Headless | **--prompt** / **-p** for non-interactive runs—pipe it, script it, bench it. |
| Hackable | TypeScript, clear agent loop, bash-first tools—fork it, shamelessly. |
Coming soon
Deeper autonomous agent testing — persistent sandbox sessions, richer browser workflows, and stronger "prove it works" evidence.
API key (pick one)
Environment (good for CI):
export GROK_API_KEY=your_key_here**.env** in the project (see .env.example if present):
GROK_API_KEY=your_key_hereCLI once:
grok -k your_key_hereSaved in user settings — ~/.grok/user-settings.json:
{ "apiKey": "your_key_here" }Optional **subAgents** — custom foreground sub-agents. Each entry needs **name**, **model**, and **instruction**:
{
"subAgents": [
{
"name": "security-review",
"model": "grok-code-fast-1",
"instruction": "Prioritize security implications and suggest concrete fixes."
}
]
}Names cannot be general, explore, vision, verify, or computer because those are reserved for the built-in sub-agents.
Optional: **GROK_BASE_URL** (default https://api.x.ai/v1), **GROK_MODEL**, **GROK_MAX_TOKENS**.
Telegram (remote control) — short version
- Create a bot with @BotFather, copy the token.
- Set
**TELEGRAM_BOT_TOKEN**or add**telegram.botToken**in~/.grok/user-settings.json(the TUI**/remote-control**flow can save it). - Start
**grok**, open**/remote-control**→ Telegram if needed, then in Telegram DM your bot:**/pair**, enter the 6-character code in the terminal when asked. - First user must be approved once; after that, it’s remembered. Keep the CLI process running while you use the bot (long polling lives in that process).
Voice & audio messages
Send a voice note or audio attachment in Telegram and Grok will transcribe it locally with whisper.cpp before passing the text to the agent. No cloud STT service is involved — everything runs on your machine.
Prerequisites
| Dependency | Why | Install (macOS) |
| --------------- | --------------------------------------------------------------- | -------------------------- |
| whisper-cli | Runs the actual speech-to-text inference | brew install whisper-cpp |
| ffmpeg | Converts Telegram voice notes (OGG/Opus) to WAV for whisper.cpp | brew install ffmpeg |
After installing, verify both are available:
whisper-cli -h
ffmpeg -versionDownload a Whisper model
Grok CLI auto-downloads the configured model on first use, but you can pre-download it:
mkdir -p ~/.grok/models/stt/whisper.cpp
curl -L https://huggingface.co/ggerganov/whisper.cpp/resolve/main/ggml-tiny.en.bin \
-o ~/.grok/models/stt/whisper.cpp/ggml-tiny.en.binAvailable models (trade size for accuracy): tiny.en (75 MB), base.en (142 MB), small.en (466 MB).
Configure in ~/.grok/user-settings.json
{
"telegram": {
"botToken": "YOUR_BOT_TOKEN",
"audioInput": {
"enabled": true,
"binaryPath": "/opt/homebrew/bin/whisper-cli",
"model": "tiny.en",
"modelPath": "~/.grok/models/stt/whisper.cpp/ggml-tiny.en.bin",
"autoDownloadModel": true,
"language": "en"
}
}
}| Setting | Default | Description |
| ------------------- | ----------------- | ------------------------------------------------------------------------ |
| enabled | true | Set to false to ignore voice/audio messages entirely. |
| binaryPath | whisper-cli | Absolute path or command name for the whisper.cpp CLI binary. |
| model | tiny.en | Model alias used for auto-download resolution. |
| modelPath | (auto-resolved) | Explicit path to a .bin model file. Overrides model + auto-download. |
| autoDownloadModel | true | Download the model into ~/.grok/models/stt/whisper.cpp on first use. |
| language | en | Whisper language code passed to the CLI. |
Optional headless flow when you do not want the TUI open:
grok telegram-bridgeTreat the bot token like a password.
Instructions & project brain
**AGENTS.md**— merged from git root down to your cwd (Codex-style; see repo docs).**AGENTS.override.md**wins per directory when present.
Project settings
Project file: **.grok/settings.json** — e.g. the current model for this project.
Sandbox
Grok CLI can run shell commands inside a Shuru microVM sandbox so the agent can't touch your host filesystem or network.
Requires macOS 14+ on Apple Silicon.
Enable it with --sandbox on the CLI, or toggle it from the TUI with /sandbox.
When sandbox mode is active you can configure:
- Network — off by default; enable with
--allow-net, restrict with--allow-host - Port forwards —
--port 8080:80 - Resource limits — CPUs, memory, disk size (via settings or
/sandboxpanel) - Checkpoints — start from a saved environment snapshot
- Secrets — inject API keys without exposing them inside the VM
All settings are saved in ~/.grok/user-settings.json (user) and .grok/settings.json (project).
Verify
Run **/verify** in the TUI or **--verify** on the CLI to verify your app locally:
grok --verify
grok -d /path/to/your/app --verifyThe agent inspects your project, figures out how to build and run it, spins up a sandbox, and produces a verification report with screenshots and video evidence. Works with any app type.
Development
From a clone:
bun install
bun run build
bun run start
# or: node dist/index.jsOther useful commands:
