Developers using AI coding tools who want to build production-ready software.
TL;DR
Vibe coding fails in production due to incomplete specs, missing context, and chaotic code. The video introduces Spec-Driven Development (SDD) using SpecKit to formalize requirements, planning, and documentation before coding, ensuring clarity and maintainability.
Key Takeaways
- Vibe coding creates an illusion of speed, but in production it leads to chaos due to incomplete requirements and lack of formal readiness checks.
- The cognitive bias 'curse of knowledge' makes developers skip obvious details, which AI then fills in incorrectly.
- Without documenting decisions, vibe coding loses context: after a week, it's impossible to understand why the code was written that way.
- Spec-Driven Development (SDD) introduces formal stages: first create a detailed spec, then a plan, and only then code.
- SDD turns implicit assumptions into explicit requirements, allowing verification before coding begins.
- The SpecKit framework automates the creation of specs and plans, generating files that become the single source of truth for the entire team.
- Transitioning from vibe coding to SDD is moving from chaotic experimentation to managed development with predictable outcomes.

Describing a task for ZTD with three planning lists.
Questions & Answers
Why is vibe coding not suitable for production?
Vibe coding is fun, but in real production problems arise: incomplete tasks, lack of completion criteria, loss of context, and chaos in large projects.
What is SDD in programming?
SDD stands for Spec Driven Development, development based on specifications. It's an approach where detailed documents (specs) are created first, then code.
How does SpecKit help in development?
SpecKit is a framework from GitHub/Microsoft for SDD. It creates specs and plans, checks quality, and generates documents that capture requirements and context.
What problems does Spec Driven Development solve?
SDD solves: unclear tasks, lack of completion criteria, loss of context, chaos in large projects, and the inability to remember why code was written that way.
How to create your first spec in SpecKit?
After installing SpecKit, run `specify init`, then `create spec`. Write a task description, and AI generates a detailed spec with user story and acceptance criteria.
Key Terms
- Vibe Coding — A style of programming with AI where the developer gives vague tasks, relying on intuition, without formal specifications.
- Spec Driven Development (SDD) — A development approach where detailed specifications are created first, and then code is written based on them.
- SpecKit — A framework from GitHub/Microsoft for SDD that automates the creation of specs, plans, and quality checks.
- Curse of Knowledge — A cognitive bias where a person assumes others know the same things, and therefore does not explain details.
