The Birth of Vibe Coding
The Accidental Discovery
Vibe coding wasn’t designed - it was discovered. Early AI adopters noticed patterns:
- Successful projects followed similar rhythms
- Failed projects made similar mistakes
- Traditional methods consistently underperformed
The name came from developers saying “you need to get into the vibe” with AI. Not just prompting - creating a flow state where human intention and AI capability merged.
The Principles
1. Documentation as Control Surface
Early adopters realized: AI treats documentation as truth. Write “this system handles millions of users” and AI codes for scale. Write “simple prototype” and AI keeps it minimal.
Discovery: Documentation isn’t describing code - it’s controlling code generation.
2. Smoke Tests as Build Verification
Problem: Without continuous testing, you don’t know if AI is building correctly until it’s too late.
Solution: Create smoke tests that verify each step of development is working as intended.
Discovery: You can’t wait until the end to test - smoke tests let you catch problems immediately as AI builds.
3. Fuzzy Architecture
Problem: Detailed upfront design leads to overengineering with AI.
Solution: Start with intentionally vague architecture that crystallizes through implementation.
Discovery: AI helps discover the right architecture by building, not by planning.
4. Continuous Anchoring
Problem: As AI works on new features, it forgets earlier requirements.
Solution: Constantly run tests to verify old functionality still works.
Discovery: AI’s limited context means you must actively maintain working state.
5. Offloading the Load
Problem: AI gets confused by inconsistent patterns and unclear structure.
Solution: Make everything explicit, consistent, and well-organized for AI.
Discovery: The easier you make AI’s job, the better results you get.
The Breakthrough Moment
The key insight: AI is not a developer, it’s an amplifier.
Traditional methods treat AI like a faster developer. Vibe coding recognizes AI as something new:
- Incredible speed, but needs direction
- Limited memory due to context windows, but vast knowledge from training
- Pattern recognition beyond human capability, but can confidently produce errors
- Surprising insights mixed with obvious mistakes
The Method Emerges
Developers started sharing patterns that would become core to vibe coding:
“DevDocs” Pattern: Excessive documentation as source of truth that guides AI “Smoke Tests” Pattern: Verbose tests that validate AI understands your intent “Fuzzy Architecture” Pattern: Start intentionally vague, let structure emerge through building “Anchor” Pattern: Force AI to verify old functionality still works after changes “Offload” Pattern: Structure everything to make AI’s job as easy as possible
These weren’t arbitrary - they solved real problems:
- DevDocs gave AI persistent context across sessions
- Smoke tests caught AI misunderstandings early
- Fuzzy architecture prevented overengineering
- Anchors prevented silent breakage as context drifted
- Offloading reduced AI confusion and errors
Why “Vibe”?
Because it captures something traditional terms miss:
- Not “engineering” - too rigid
- Not “crafting” - too slow
- Not “hacking” - too chaotic
Vibe coding is like jazz. Structure + improvisation. Rules + intuition. Human creativity + AI capability.
The Community Forms
Discord servers. GitHub repos. Blog posts. Developers sharing what worked, warning what didn’t. Patterns refined through thousands of projects.
Common realization: This isn’t a fad. It’s how development works now.
The Present
Today, vibe coding is:
- Documented methodology, not just intuition
- Proven patterns, not just preferences
- Growing community, not just early adopters
The future isn’t AI replacing developers. It’s developers wielding AI through vibe coding.
After two years of AI-assisted development, I documented the patterns that emerged: Vibe-Driven Development
This is an online book that introduces vibe coding patterns such as DevDocs, smoke tests, anchor pattern, and more. For a quick overview, check out Appendix 1, where I provide ready-to-use prompts for starting a new AI-driven project.

Since GPT-3.5’s release, I’ve been deep in AI-assisted coding. I began noticing I was unconsciously following certain patterns. Through many projects, I refined these patterns into a fairly reliable methodology.
When I explained these ideas to developer friends who knew about my AI coding work, they found the logic compelling. That motivated me to document everything properly.
I don’t claim this is definitive - I know many of you are probably following similar approaches, even if unnamed or unpublished. I’d love to hear your thoughts, whether you think I’m onto something or completely off base.
