Security & Permissions

What this skill does:

  • Sends chat prompts to xAI's API at api.x.ai
  • Vision mode sends images to xAI for analysis
  • scripts/models.js lists available models (read-only)

What this skill does NOT do:

  • Does not read arbitrary local files — --image only accepts files with image extensions (.jpg, .jpeg, .png, .gif, .webp)
  • Does not read config files or access the filesystem beyond the specified image path
  • Does not store conversation history or logs
  • Does not send credentials to any endpoint other than api.x.ai
  • Cannot be invoked autonomously by the agent (disable-model-invocation: true)

Bundled scripts: scripts/chat.js (chat), scripts/models.js (list models), scripts/search-x.js (X search)

Review scripts before first use to verify behavior.
