/music-generation

name: music-generation
description: Use this skill when the user requests to generate, create, compose, or produce music or songs — background music, theme songs, jingles, or instrumental tracks. Generates a song from a style/mood prompt and optional lyrics via the MiniMax music API.

Music Generation Skill

Overview

This skill generates songs (vocal or instrumental) from a structured JSON spec using the MiniMax music generation API (`/v1/music_generation`). You describe the style/mood/scene in `prompt`, optionally provide `lyrics`, and the script returns an MP3.

Workflow

Step 1: Understand Requirements

Identify the desired style, mood, scene, language, and whether the user wants vocals or a pure instrumental track. Decide whether to supply lyrics or let the model write them.

Step 2: Create the Spec JSON

Write a JSON file in `/mnt/user-data/workspace/` named `{descriptive-name}.json`:

{
  "title": "Rainy Night Cafe",
  "prompt": "indie folk, melancholic, introspective, walking alone, cafe",
  "lyrics": "[verse]\nStreetlights glow the night wind sighs\n[chorus]\nPush the wooden door warm air inside"
}

Fields:

• `title` (optional): a human-readable name.
• `prompt` (required): style, mood, and scene. Drives the musical character.
• `lyrics` (optional): song lyrics. Use `\n` between lines and structure tags such as

`[Intro]`, `[Verse]`, `[Pre Chorus]`, `[Chorus]`, `[Bridge]`, `[Outro]`.

• `is_instrumental` (optional, bool): set `true` for a pure instrumental track (no lyrics needed).

Behavior:

• `lyrics` provided → those lyrics are sung.
• `is_instrumental: true` → instrumental, no vocals.
• neither → the model auto-writes lyrics from `prompt` (`lyrics_optimizer`).

Step 3: Execute Generation

python /mnt/skills/public/music-generation/scripts/generate.py \
  --prompt-file /mnt/user-data/workspace/rainy-night-cafe.json \
  --output-file /mnt/user-data/outputs/rainy-night-cafe.mp3

Parameters:

• `--prompt-file`: Absolute path to the JSON spec (required).
• `--output-file`: Absolute path for the output MP3 (required).

[!NOTE] Do NOT read the python file, just call it with the parameters.

Environment

• `MINIMAX_API_KEY` (required): your MiniMax interface key.
• `MINIMAX_API_HOST` (optional): default `https://api.minimaxi.com`.
• `MINIMAX_MUSIC_MODEL` (optional): default `music-2.6-free` (works for all API-key users);

paid/Token-Plan users can set `music-2.6` for higher limits.

Output Handling

• Music is saved as MP3 (typically in `/mnt/user-data/outputs/`).
• Share the generated file with the user using the present_files tool.
• Offer to iterate on style or lyrics if adjustments are needed.

Notes

• Keep `prompt` focused on style/mood/scene; put the actual sung words in `lyrics`.
• For non-English songs, write `lyrics` in the target language.
