Decompose — Project Scope Analysis

Analyze project scope and determine whether to treat it as a single feature or split into multiple sub-features before entering the spec chain.

Core Principles

1. Lightweight: 3-5 rounds of questions, not a deep investigation
2. Boundary-focused: Only care about scope boundaries and dependencies
3. No demand validation: That is /idea's responsibility
4. No deep research: That is /prd's responsibility
5. Single is valid: Not every project needs splitting — a single-feature verdict is a good outcome

Workflow

Step 1: Read Context

Scan the project to understand what exists:

1. Use Glob to scan the project directory tree (top 3 levels)
