xAI Image Generate

Use this skill for xAI/Grok Imagine image requests through the Grok-connected xAI image-generation tool.

Preferred Grok Tool Flow

1. Use search_tool to discover the available tool schema first:

{
  "query": "xai image generate"
}

2. Call the returned xAI image-generation MCP tool with the schema it reports. A typical payload is:

{
  "prompt": "tiny minimalist blue dot icon on white background",
  "resolution": "2k",
  "artifact_dir": ".grok-xai-artifacts"
}

For base64 image payloads saved locally, request the response format supported by the tool schema and pass an artifact directory when available.

Options

• prompt: required image prompt.
• model: defaults are tool-owned unless the user asks for a specific model.
• n: number of images.
• resolution: commonly 1k or 2k when supported.
• response_format: url or b64_json when supported.
• size: provider-specific size string.
• artifact_dir: local directory for saved image artifacts, when supported.

When artifact_dir is present, return the upstream JSON plus artifact metadata. Saved artifacts should include a local path, mime_type, source, and status when the tool provides them. If a remote URL cannot be downloaded, preserve its upstream URL instead of hiding it.

Credential Safety

Use existing Grok/xAI credentials exposed by the host or MCP server. Never print, quote, summarize, or store OAuth tokens, refresh tokens, bearer tokens, or API keys.
