  1. Download the package from Yavira.
  2. Extract it into a folder your agent can access.
  3. Paste one of the prompts below and point your agent at the extracted folder.
New install

I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.

Upgrade existing

I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise.

grok-image-cli

A CLI for generating and editing images using the xAI Grok API. Supports multiple models: grok-imagine-image (default), grok-imagine-image-pro, grok-2-image-1212. Powered by the official @ai-sdk/xai SDK. Credentials are stored in the OS native credential store (macOS Keychain, Windows Credential Manager, Linux Secret Service) via cross-keychain.

Installation

Requires Node.js >= 20.19.0. Works on macOS, Windows, and Linux. The package is fully open source under the MIT license: https://github.com/cyberash-dev/grok-image-cli npm install -g grok-image-cli The npm package is published with provenance attestation, linking each release to its source commit via GitHub Actions. You can verify the published contents before installing: npm pack grok-image-cli --dry-run Install from source (if you prefer to audit the code before running): git clone https://github.com/cyberash-dev/grok-image-cli.git cd grok-image-cli npm install && npm run build && npm link After installation the grok-img command is available globally.

Quick Start

grok-img auth login # Interactive prompt: enter xAI API key grok-img generate "A futuristic city skyline at night" # Generate with default model grok-img generate "A futuristic city skyline at night" -m grok-imagine-image-pro # Use pro model grok-img edit "Make it a watercolor painting" -i ./photo.jpg # Edit an existing image

API Key Management

Store API key (interactive prompt): grok-img auth login Show stored key (masked) and source: grok-img auth status Remove key from credential store: grok-img auth logout The CLI also supports the XAI_API_KEY environment variable as a fallback when no credential store entry is found.

Image Generation

grok-img generate "A collage of London landmarks in street-art style" grok-img generate "Mountain landscape at sunrise" -n 4 -a 16:9 grok-img generate "A serene Japanese garden" -o ./my-images grok-img generate "Photorealistic portrait" -m grok-imagine-image-pro grok-img generate "Abstract art" -m grok-2-image-1212

Image Editing

Edit a local file or a remote URL: grok-img edit "Change the landmarks to New York City" -i ./landmarks.jpg grok-img edit "Render as a pencil sketch" -i https://example.com/portrait.jpg grok-img edit "Add a vintage film grain effect" -i ./photo.jpg -a 3:2 -o ./edited

Security and Data Storage

The following properties are by design and can be verified in the source code: xAI API key: stored in the OS native credential store via cross-keychain (macOS Keychain / Windows Credential Manager / Linux Secret Service; service: grok-image-cli, account: api-key). By design, never written to disk in plaintext. If no credential store entry is found, the CLI falls back to the XAI_API_KEY environment variable. See src/infrastructure/adapters/credential-store.adapter.ts for the implementation. No config files: all settings are passed via CLI flags. Nothing is stored on disk besides the credential store entry. Network: the API key is only sent to api.x.ai over HTTPS via the official @ai-sdk/xai SDK. When editing images with a remote URL (-i https://...), the SDK makes an additional outbound HTTPS request to fetch the source image. No other outbound connections are made by the CLI itself (npm/git fetches during installation are standard package manager behavior). See src/infrastructure/adapters/grok-api.adapter.ts. Generated images: saved to the local output directory (default: ./grok-images). No images are cached or uploaded elsewhere.
