Deep Interview

Spec-first development. Ask hard questions now, avoid expensive rework later.

The Pattern

Feature description → Pointed questions (8-15 rounds) → Polished @spec.md → Implementation

When to Use

• New flows touching 3+ screens
• New data models or persistence changes
• Architectural decisions with real trade-offs
• Features with non-obvious edge cases
• Anything where "just build it" would lead to rework

When NOT to Use
