## API Reference

xAI API Docs: https://docs.x.ai/api

## Environment Variables

- `XAI_API_KEY` - Your xAI API key (required)
- `XAI_MODEL` - Default model (optional, defaults to grok-3)

## 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.
