Spec-Driven Development Guide: AI Coding Agents Workflow (40-Page PDF)

Stop vibe coding. Start shipping software your AI agent actually builds right the first time.

Spec-Driven Development (SDD) flips the usual workflow: instead of throwing a vague request at your coding agent and debugging the guesswork, you describe WHAT to build, refine it through structured phases, and let the agent produce the HOW. This complete 40-page guide teaches the entire method using GitHub's open-source Spec Kit toolkit — from your first install to running the full workflow on real, production work.

WHAT YOU'LL LEARN
- What Spec-Driven Development is, and why intent — not code — becomes the source of truth
- Installing the Specify CLI (uv, uvx, pipx) and scaffolding your first project
- The constitution: the non-negotiable rules that govern everything else
- The full workflow, command by command: specify, clarify, plan, checklist, tasks, analyze, implement, converge
- Scaling with extensions, presets, and bundles
- Working across 30+ AI coding agents with no lock-in
- Modernizing brownfield and legacy codebases one specified slice at a time
- A 30-day adoption plan, common pitfalls, and using SDD across a team
- A complete worked example (Taskify) walking through all nine phases end to end

WHO IT'S FOR
Developers, tech leads, and AI-assisted builders who want reliable, repeatable results from coding agents instead of endless prompt-and-fix loops. No prior SDD experience required.
