Stop Vibe Coding, Use Spec-Driven Development Instead
The article argues against 'vibe coding' where developers describe a feature in natural language and let AI generate the code. Instead, it proposes a 'spec-driven development' approach where senior engineers write detailed specifications first before using AI.
Why it matters
This approach can help organizations scale their use of AI in software development while maintaining code quality and control.
Key Points
- 1Vibe coding leads to issues like unreviewable code, unintended features, and codebase rewrites
- 2Spec-driven development involves writing 3 key documents: Product Requirements Doc, Technical Design Doc, and AI Spec
- 3The AI works from the precise spec, not from natural language prompts
- 4This 5-step workflow (write specs, generate AI spec, run agent, review diff) results in reviewable, production-ready code
Details
The article criticizes the 'vibe coding' approach where junior developers describe a feature in natural language and let AI generate the code. While this may seem fast, it leads to issues at scale like large amounts of unreviewable code, unintended features, and AI agents rewriting significant portions of the codebase. Instead, the author proposes a 'spec-driven development' approach where senior engineers first write detailed specifications before using AI. This includes a Product Requirements Doc, Technical Design Doc, and a precise AI Spec that outlines the expected behavior, edge cases, and what the AI should not touch. The AI then works from this spec, not from open-ended prompts, resulting in reviewable and production-ready code. The 5-step workflow involves writing the specs, generating the AI spec, running the agent, and reviewing the diff rather than the entire codebase.
