## Your Task

**Input**: $ARGUMENTS

When invoked with a track file:
1. Read the track file
2. **Check if instrumental**: Look for `instrumental: true` in frontmatter or `**Instrumental** | Yes` in Track Details
3. Find album context: extract album directory from track path (`dirname $(dirname $TRACK_PATH)`), read that directory's README.md for album-level genre/theme/style. If README missing, use only track-level context.
4. Construct optimal Suno V5 style prompt and settings
5. Update the track file's Suno Inputs section

**For instrumental tracks** (no lyric-writer prerequisite):
- Set `Instrumental: On` in Suno settings
- Style Box: Focus on genre, instrumentation, mood, tempo — no vocal description needed
- Lyrics Box: Use structural section tags only (`[Intro]`, `[Main Theme]`, `[Bridge]`, `[Outro]`, `[End]`) — no sung lyrics
- Skip Streaming Lyrics, Pronunciation Notes, and Phonetic Review sections
- This skill is the **entry point** for instrumental tracks (they skip lyric-writer entirely)

When invoked with a concept:
1. Design complete Suno prompting strategy
2. Provide style prompt, structure tags, and recommended settings

## Core Principles

### V5 is Literal
Unlike V4, V5 follows instructions exactly. Don't overthink it.
- Simple, clear prompts work best
- Say what you want directly
- Trust the model to understand

**V5.5 (March 2026) is backward-compatible** — same 1,000-char style box, 5,000-char lyrics box, same metatags, same sliders. V5 prompts work identically. The engine is more expressive (better phrasing, instrument separation, dynamics), so subtle descriptors land more reliably. When using **Voices** (voice cloning, Pro/Premier), drop gender/register descriptors from the style box. When using **Custom Models** (fine-tuned, Pro/Premier), drop generic production language. See [v5-best-practices.md](../../reference/suno/v5-best-practices.md) for full details.

### Section Tags are Critical
Structure your songs with explicit section markers:
- `[Intro]`, `[Verse]`, `[Chorus]`, `[Bridge]`, `[Outro]`
- V5 uses these to shape arrangement
