# 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`:

```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

```bash
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.
