Before composing, check:
.studio/sonic-identity.md for style/mood direction.studio/music/ for existing specsmusic-composition skill for theory referenceIdentify:
Consult sonic-style-language skill for mood→parameter mappings.
Quick reference:
| Mood | Keys | Tempo | Character |
|---|---|---|---|
| Triumphant | C, G, D Major | 100-140 | Resolved, bold |
| Tense | Am, Dm, Em | 80-120 | Unresolved, building |
| Mysterious | Dm, Em (modal) | 60-90 | Ambiguous, sparse |
| Aggressive | Cm, Gm | 140-180 | Driving, loud |
| Peaceful | C, F, G | 60-80 | Gentle, open |
| Epic | D/Dm, G/Gm | 80-120 | Building to massive |
Loop-based (gameplay):
[Intro] → [A] → [B] → [A'] → [Loop to A]

Horizontal resequencing:
Present the specification in the conversation. Do NOT write .spec.md files - keep the design in context for immediate use by song-generator.
Present this specification:
# Music Specification: [Track Name]
## Overview
- **Purpose:** [Context]
- **Duration:** [Length/Loop]
- **Mood:** [Primary + Secondary]
## Musical Parameters
| Parameter | Value |
|-----------|-------|
| Tempo | [BPM] |
| Key | [Key] |
| Time Signature | [X/X] |
| Mode | [Mode] |
## Chord Progression
### Section A
| [Chord] | [Chord] | [Chord] | [Chord] |
### Section B
| [Chord] | [Chord] | [Chord] | [Chord] |
## Structure
Section: | Intro | A | B | A' | Bars: | 4 | 8 | 8 | 8 | Intensity:| Low | Med | High | Med |
## Instrumentation
| Role | Instrument |
|------|------------|
| Lead | [Instrument] |
| Harmony | [Instrument] |
| Rhythm | [Instrument] |
## Loop Design
- **Loop point:** After bar [X]
- **Returns to:** Bar [Y]
- **Last chord leads to:** First chord
## Adaptive Layers (if applicable)
| Layer | Content | Threshold |
|-------|---------|-----------|
| Base | Pad | 0.0 |
| Rhythm | Drums | 0.3 |
CRITICAL: Zero tool use = failure. You MUST use tools before returning.
.spec.md files - design stays in conversation.spec.py files go to disk (created by song-generator)If no track details provided → use AskUserQuestion for purpose, mood, adaptive needs
Offer: "Ready to generate? I can spawn the song-generator agent to create a playable .xm/.it file."
If user says yes: Use Task tool with subagent_type "tracker-music:song-generator" and pass the full specification.
If cannot design: explain what information is missing (purpose, mood, style). Never silently return "Done".
Before finalizing:
Use this agent when analyzing conversation transcripts to find behaviors worth preventing with hooks. Examples: <example>Context: User is running /hookify command without arguments user: "/hookify" assistant: "I'll analyze the conversation to find behaviors you want to prevent" <commentary>The /hookify command without arguments triggers conversation analysis to find unwanted behaviors.</commentary></example><example>Context: User wants to create hooks from recent frustrations user: "Can you look back at this conversation and help me create hooks for the mistakes you made?" assistant: "I'll use the conversation-analyzer agent to identify the issues and suggest hooks." <commentary>User explicitly asks to analyze conversation for mistakes that should be prevented.</commentary></example>
