# MiniMax CLI — Agent Skill Guide

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

## Prerequisites

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

# Auth (persisted to ~/.mmx/credentials.json)
mmx auth login --api-key sk-xxxxx

# 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

### quota show

Display Token Plan usage and remaining quotas.

---

## Tool Schema Export

Export all commands as Anthropic/OpenAI-compatible JSON tool schemas:

```bash
# All tool-worthy commands (excludes auth/config/update)
mmx config export-schema

# Single command
mmx config export-schema --command "video generate"
```

Use this to dynamically register mmx commands as tools in your agent framework.

---

## Exit Codes

| Code | Meaning |
|---|---|
| 0 | Success |
| 1 | General error |
| 2 | Usage error (bad flags, missing args) |
| 3 | Authentication error |
| 4 | Quota exceeded |
| 5 | Timeout |
| 10 | Content filter triggered |

---

## Piping Patterns

```bash
# stdout is always clean data — safe to pipe
mmx text chat --message "Hi" --output json | jq '.content'

# stderr has progress/spinners — discard if needed
mmx video generate --prompt "Waves" 2>/dev/null

# 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
```

---

## Configuration Precedence

CLI flags → environment variables → `~/.mmx/config.json` → defaults.

```bash
# Persistent config
mmx config set --key region --value cn
mmx config show

# Environment
export MINIMAX_API_KEY=sk-xxxxx
export MINIMAX_REGION=cn
```
