How to Write a Good Spec for AI Agents ↗

Editorial Notes

This is the practical core of SDD — the article you will return to repeatedly. Osmani provides concrete templates for structuring specifications, with side-by-side comparisons of vague prompts versus precise specs and their resulting code quality. Focus on the section about defining constraints and acceptance criteria — these are what transform a wish list into an actionable contract that an AI agent can verify against. Bookmark the spec template and adapt it to your own projects.
