Section Guidelines
One-Line Definition
- Must be a single sentence
- Include: what it is, how it differs, core value
- Example: "A lightweight screen recorder that matches GNOME Screencast's minimal UX, adds audio capture, and supports basic post-capture annotation."
Top Principles
- 3-5 guiding principles
- Drive prioritization decisions
- Examples: "Quickly deliverable MVP", "Cross-platform support", "Minimal UI"
Feature Sections (1-6)
- Use tables for consistency
- Mark support: ✅ (yes), ❌ (no), Optional, Basic
- Group related features
- Section names vary by product type
UI/UX Principles
- Reference existing UX patterns when applicable
- Define the "feel" of the product
- Include mode-based behavior if relevant
Platform Scope
- List all target platforms
- Mark priority: Primary, Supported, Future
- Be explicit about what's NOT supported initially
Non-Goals
- Critical section—prevents scope creep
- List features explicitly excluded
- Mark all with ❌
- Include common requests that won't be built
