Stop Vibe Coding.
Start Spec-Driven Development

Turn your intent into crystal-clear specifications that AI can reliably execute. No more guesswork, no more surprises.

Why "Vibe Coding" Fails

❌ Without Specs

  • • Vague prompts → guessed requirements
  • • Code looks right but doesn't work
  • • No validation checkpoints
  • • Broken on complex projects
  • • Hours debugging AI hallucinations

✅ With Spec-Driven

  • • Clear specifications = clear intent
  • • AI builds exactly what you want
  • • 4-phase validation process
  • • Scales to enterprise projects
  • • Predictable, production-ready code

The 4-Phase Workflow

Each phase has a specific job. You validate before moving forward. No surprises, no rewrites.

1. Specify

Define the What & Why

Describe user journeys, experiences, and success criteria. AI generates a detailed spec you review and refine.

2. Plan

Technical Blueprint

Provide your stack, architecture, constraints. AI creates a comprehensive technical plan respecting your standards.

3. Tasks

Break Into Chunks

AI transforms spec + plan into small, reviewable tasks. Each task is testable in isolation.

4. Implement

Build & Validate

AI tackles tasks one by one. Review focused changes instead of thousand-line code dumps.

Why This Works (And Vague Prompts Don't)

Language models excel at pattern completion, not mind reading. A vague prompt like "add photo sharing to my app" forces the AI to guess thousands of unstated requirements.

Spec-Driven gives AI clarity: Instead of guessing, it knows what to build (spec),how to build it (plan), and in what sequence (tasks). The result? Reliable, production-ready code.

Where Spec-Driven Shines

🚀 Greenfield (0→1)

Starting new? Spec-Driven ensures AI builds what you intend, not generic patterns.

🔧 Feature Work (N→N+1)

Adding features to complex codebases? Specs keep new code native to your architecture.

🏗️ Legacy Modernization

Rebuilding old systems? Capture business logic in modern specs, eliminate tech debt.
