Spec Dojo · Academy for Spec-Driven Development

AI coding with understanding, not vibes.

The AI sprint was euphoric. Then came six months of archaeology. I see this in almost every team that goes fast with AI. Spec-Driven Development keeps the pace and keeps the understanding.

The real problem

Writing got 10× faster. Understanding didn't.

AI writes code at piece-rate. A new class of debt grows with it. Unnoticed. It comes due in the incident, not in the sprint.

Comprehension Debt

Code nobody understands anymore. And nobody knows what they don't know. More expensive than any technical debt.

Flying blind on security

~45 % of AI code ships with a hole, 86 % fail XSS, 88 % fail log injection. Untrusted input that slips through review.

Write-Only Culture

Generating is cheaper than searching. So the codebase grows. And Comprehension Coverage drops.

What you're dealing with

~45 %

AI code with a security flaw (Veracode, 100+ LLMs)

86 %

don't prevent XSS

~100k

token Smart Zone, then the model drifts

8×

the same code duplicated. That's debt, not speed

The course

Six modules along the real workflow.

From the foundation into production, following one B2B SaaS team (TechFlow Software, 18 people, Linz).

01The Foundation Vibe Coding vs. SDD, Context-Reset, the constitution of your repo. 02Align before any code The AI grills you, you grill the AI. The alignment document as a contract. 03Plan in reviewable slices Size slices to human understanding, Definition of Done. 04Build and verify Trust Cap on tests, AI code as untrusted input, explain it blind. 05Clean up and keep understanding Atomic commits with intent, Living-Spec folding, the Comprehension Artifact. 06AI in production Queues, Circuit Breakers, observability, safety-critical, Intent Manager.

"If you couldn't explain it in a postmortem, you shouldn't have shipped it."

Who it's for

For teams that take AI seriously.

Tech leads & developers

In 5 to 50-person teams that want to use AI assistants productively, without senior burnout and rising security findings.

Solo & indie hackers

Who build with Claude Code, Cursor or Codex and want to keep the pace, without losing track of their own code in six months.

CTOs & engineering managers

Who need a repeatable workflow and metrics that measure understanding, not lines of code.
