# MiniMax CLI — Agent Skill Guide

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

## When to Use

Use this skill when the user wants to generate or inspect text, images, video, speech, music, web-search results, or MiniMax API resources through the `mmx` terminal CLI.

## 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 |

---

## Commands

### text chat

Chat completion. Default model: `MiniMax-M3`. Pass `--model MiniMax-M2.7` for the previous-generation default when reproducing older outputs.

```bash
mmx text chat --message <text> [flags]
```

```bash
# Single message (uses MiniMax-M3 by default)
mmx text chat --message "user:What is MiniMax?" --output json --quiet

# Multi-turn with system prompt
mmx text chat \
  --system "You are a coding assistant." \
  --message "user:Write fizzbuzz in Python" \
  --output json

# Pin to the previous-generation model
mmx text chat --model MiniMax-M2.7 --message "user:Hello" --output json

# From file
cat conversation.json | mmx text chat --messages-file - --output json
```

---

### image generate

Generate images. Model: `image-01`.

```bash
mmx image generate --prompt <text> [flags]
```

```bash
mmx image generate --prompt "A cat in a spacesuit" --output json --quiet
mmx image generate --prompt "Logo" --n 3 --out-dir ./gen/ --quiet
```

---

### video generate

Generate video. Default model: `MiniMax-Hailuo-2.3`. Async task — polls until completion by default.

```bash
mmx video generate --prompt <text> [flags]
```

```bash
# Non-blocking: get task ID
mmx video generate --prompt "A robot." --async --quiet

# Blocking: wait and save file
mmx video generate --prompt "Ocean waves." --download ocean.mp4 --quiet
```

---

### speech synthesize

Text-to-speech. Default model: `speech-2.8-hd`. Max 10k chars.

```bash
mmx speech synthesize --text <text> [flags]
```

```bash
mmx speech synthesize --text "Hello world" --out hello.mp3 --quiet
echo "Breaking news." | mmx speech synthesize --text-file - --out news.mp3
```

---

### music generate

Generate music. Model: `music-2.6-free`.

```bash
mmx music generate --prompt <text> [--lyrics <text>] [flags]
```

```bash
# Instrumental
mmx music generate --prompt "Cinematic orchestral, building tension" --instrumental --out bgm.mp3 --quiet

# With auto-generated lyrics
mmx music generate --prompt "Upbeat pop about summer" --lyrics-optimizer --out summer.mp3 --quiet
```

---

### search query

Web search via MiniMax.

```bash
mmx search query --q "MiniMax AI" --output json --quiet
```

---

### vision describe

Image understanding via VLM.

```bash
mmx vision describe --image photo.jpg --prompt "What breed?" --output json
```

---

## Piping Patterns

```bash
# Chain: generate image → describe it
URL=$(mmx image generate --prompt "A sunset" --quiet)
mmx vision describe --image "$URL" --quiet

# Async video workflow
TASK=$(mmx video generate --prompt "A robot" --async --quiet | jq -r '.taskId')
mmx video task get --task-id "$TASK" --output json
mmx video download --task-id "$TASK" --out robot.mp4
```

---

## Exit Codes

| Code | Meaning |
|---|---|
| 0 | Success |
| 1 | General error |
| 2 | Usage error |
| 3 | Authentication error |
| 4 | Quota exceeded |
| 5 | Timeout |
| 10 | Content filter triggered |

---

## Limitations

- Requires a configured MiniMax account and valid authentication before any API-backed command will work.
- Media-generation tasks can be async, quota-limited, or region-constrained; agents should handle delayed completion and provider-side failures explicitly.
- This skill documents CLI usage only and does not replace provider policy review, content-safety checks, or downstream file validation.
