# ACE-Step Music Generation Skill

Use ACE-Step V1.5 API for music generation. **Always use `scripts/acestep.sh` script** — do NOT call API endpoints directly.

## Quick Start

```bash
# 1. cd to this skill's directory
cd {project_root}/{.claude or .codex}/skills/acestep/

# 2. Check API service health
./scripts/acestep.sh health

# 3. Generate with lyrics (recommended)
./scripts/acestep.sh generate -c "pop, female vocal, piano" -l "[Verse] Your lyrics here..." --duration 120 --language zh

# 4. Output saved to: {project_root}/acestep_output/
```

## Workflow

For user requests requiring vocals:
1. Use the **acestep-songwriting** skill for lyrics writing, caption creation, duration/BPM/key selection
2. Write complete, well-structured lyrics yourself based on the songwriting guide
3. Generate using Caption mode with `-c` and `-l` parameters

Only use Simple/Random mode (`-d` or `random`) for quick inspiration or instrumental exploration.

If the user needs a simple music video, use the **acestep-simplemv** skill to render one with waveform visualization and synced lyrics.

**MV Production Requirements**: Making a simple MV requires three additional skills to be installed:
- **acestep-songwriting** — for writing lyrics and planning song structure
- **acestep-lyrics-transcription** — for transcribing audio to timestamped lyrics (LRC)
- **acestep-simplemv** — for rendering the final music video

## Script Commands

**CRITICAL - Complete Lyrics Input**: When providing lyrics via the `-l` parameter, you MUST pass ALL lyrics content WITHOUT any omission:
- If user provides lyrics, pass the ENTI
