MiniMax-H3 Video With MMX

Use this skill only for MiniMax-H3 video generation. Do not handle text, image generation, speech, music, search, legacy Hailuo models, or unrelated MMX commands.

Before a paid request, read references/h3-video.md for prompt construction, media constraints, waiting behavior, and failure handling.

Required Rules

1. Use a Pay-as-you-go/Credit API Key. H3 does not use OAuth or Token Plan Subscription Keys.
2. Reuse a saved MMX API key when available. Never print, repeat, or place a literal API key in a command transcript.
3. Always pass --model MiniMax-H3; never rely on the configured default model.
4. For a completed video, run one direct blocking mmx video generate command. Do not use Bash wrappers or hand-written polling loops.
5. If the terminal command remains active, wait on that exact execution session. Do not run ps, scrape process arguments, inspect the output repeatedly, kill the process, or submit another task.
6. Treat Detecting region... cn or Detecting region... global as normal stderr progress, not a submission failure.
7. Never submit a replacement paid task because terminal waiting, status polling, or downloading was interrupted.
8. Retry the alternate region at most once, and only when the first command clearly failed before task creation because of region detection, endpoint, or authentication routing.
9. Use --async only when the user explicitly wants a task ID without waiting or downloading.

Resolve The CLI

Inside the minimax-cli repository, build changes and use the local artifact:

bun run build
node ./dist/mmx.mjs video generate --help

Outside the repository, use the installed mmx executable. Do not install or update MMX unless the user asks.

In commands below, replace mmx with node ./dist/mmx.mjs when testing the local repository build.

Resolve And Save The API Key

Before the first paid H3 request, inspect the active credential without exposing it:
