Spec-Driven Development with Claude and GPT
Treat the spec as the single source of truth — let AI generate code, tests, and docs from it.
Creators · AI-Assisted Coding · ~7 min read
The premise
When the spec is precise, AI is excellent at filling in code, tests, and docs that conform to it.
What AI does well here
- Generate request/response handlers from an OpenAPI spec.
- Produce contract tests that fail when behavior diverges.
- Keep README sections in sync with the spec.
What AI cannot do
- Decide whether the spec itself captures the right business rules.
- Reconcile conflicting specs across services.
Key terms in this lesson
Practice this safely
Use a small project example from your own work. The useful move is to compare the AI's draft against your goal, sources, and constraints before you trust it.
- 1Ask AI to explain spec-first in plain language, then underline anything that sounds uncertain or too broad.
- 2Give it one detail from "Spec-Driven Development with Claude and GPT" and ask for two possible next steps plus one reason each step might be wrong.
- 3Check contract testing against a trusted source, teacher, adult, expert, or original document before you use it.
