# MiniMax CLI — Agent Skill Guide

Use `mmx` to generate text, images, video, speech, transcribe audio, and perform web search via the MiniMax AI platform.

## Prerequisites

```bash
# Install
npm install -g mmx-cli

# Auth (OAuth persists to ~/.mmx/credentials.json, API key persists to ~/.mmx/config.json)
mmx auth login --api-key sk-xxxxx

# Verify active auth source
mmx auth status

# Or pass per-call
mmx text chat --api-key sk-xxxxx --message "Hello"
```

Region is auto-detected. Override with `--region global` or `--region cn`.

## Agent Flags

Always use these flags in non-interactive (agent/CI) contexts:

| Flag | Purpose |
|---|---|
| `--non-interactive` | Fail fast on missing args instead of prompting |
| `--quiet` | Suppress spinners/progress; stdout is pure data |
| `--output json` | Machine-readable JSON output |
| `--async` | Return task ID immediately (video generation) |
| `--dry-run` | Preview the API request without executing |
| `--yes` | Skip confirmation prompts |

| `--messages-file <path>` | string | JSON file with messages array. Use `-` for stdin |
| `--system <text>` | string | System prompt |
| `--model <model>` | string | Model ID (default: `MiniMax-M3`) |
| `--max-tokens <n>` | number | Max tokens (default: 4096) |

| `--top-p <n>` | number | Nucleus sampling threshold |
| `--stream` | boolean | Stream tokens (default: on in TTY) |
| `--tool <json-or-path>` | string, repeatable | Tool definition JSON or file path |
