Cracking the Code of Vibe Coding
Why describing what you want to build through feeling and intent produces better software than technical specifications. The philosophy and practice of vibe coding.
What Is Vibe Coding?
Vibe coding is a term that's gained traction in the AI development community to describe a fundamentally different approach to building software. Instead of writing detailed technical specifications, you describe the experience you want to create.
Pete Sena traces the concept to a broader shift in software development: as AI tools handle more implementation detail, the human role shifts from specifying HOW to build something to expressing WHAT it should feel like.
'Build me a task manager that feels like a calm Japanese garden — minimal, intentional, with gentle transitions between states.'
This is a valid and productive prompt for AI coding tools. Not because 'Japanese garden' is a technical specification, but because AI tools have been trained on enough implementations to translate emotional and aesthetic intent into concrete design decisions.
Why Vibes Work
AI Models Understand Aesthetics
LLMs have processed millions of design discussions, reviews, and implementations. They understand that 'calm' means soft colors, generous whitespace, and slow animations. This aesthetic understanding is a genuine capability, not a gimmick.
Vibes Prevent Over-Specification
Traditional specs often over-constrain the solution. By specifying '16px padding, #3B82F6 blue, 300ms transition,' you've removed the AI's ability to find a better combination. Vibes let the AI explore the solution space more freely.
Vibes Communicate Intent
A vibe description communicates WHY something should look a certain way, not just WHAT it should look like. This context helps AI make better decisions on aspects you haven't explicitly specified.
Vibes Are Collaborative
Vibe coding feels like a creative conversation, not a command sequence. You describe, the AI interprets, you refine. This back-and-forth produces results neither party would create alone.
Practical Patterns
How to apply vibe coding in practice.
Start with a reference
Name products, brands, or experiences that embody the vibe: 'Think Linear meets Notion — clean, fast, keyboard-first.' References are more effective than abstract descriptions.
Describe the user's emotional state
How should the user FEEL when using your product? 'Confident and in control,' 'Relaxed and creative,' 'Focused and productive.' These emotional targets guide hundreds of micro-decisions.
Iterate with vibe adjustments
Refine using feeling-based feedback: 'Too corporate — make it more playful,' 'Too noisy — simplify,' 'The motion feels sluggish — make it snappier.' These descriptions are surprisingly effective with AI tools.
Extract specifics when the vibe is right
Once the feel is correct, extract the technical details: 'What exact values are you using for spacing, colors, and animation timing?' Lock these in as your design specifications.
Vibes vs Specs
Vibe coding doesn't replace technical specifications — it precedes them. The flow is:
Vibe → Prototype → Specs → Production
Traditional development skips the vibe phase, going straight from specs to production. This produces technically correct but emotionally flat products.
Vibe coding adds the exploration phase that great designers have always used — but makes it accessible to developers and product managers who can now participate in design decisions through natural language.
The best products use both: vibe coding for exploration and direction, specifications for production fidelity. Neither alone is sufficient.
