Vibe-Driven Development (VDD)

Summary

VDD bridges the gap between informal AI-assisted coding and software engineering discipline. Rather than introducing novel concepts, it systematizes practices developers already use intuitively when working with AI tools. The methodology addresses two failure modes: treating AI as a mere syntax generator, or relinquishing control entirely.

The Four Pillars

VDD rests on four core principles:

1. Radical Transparency — Make tests, data flows, and transformations visible. Hidden behavior creates debugging nightmares when AI generates unexpected code paths.
2. Verbose Communication — Tests explain functionality clearly. The test suite becomes documentation for both humans and AI agents.
3. Explicit Over Implicit — Avoid hidden behaviors or assumptions. Every behavior should be traceable to a visible source.
4. Human-in-the-Loop — Maintain developer control while leveraging AI capabilities. AI accelerates; humans steer.

Essential Patterns

The methodology introduces specific patterns for implementation:

• DevDocs — Structured documentation that AI agents can consume
• Anchor — Fixed reference points in code that guide AI decisions
• Smoke Tests — Quick validation checks after every AI-generated change
• Fuzzy Architecture — Flexible system design that accommodates AI-generated variations

Target Audience

VDD addresses developers frustrated with:

• AI-generated code that looks right but breaks in production
• Codebases that remain unclear despite having tests
• Simple changes that cause unexpected cascading failures
