What we'll cover

An AI agent writes code faster than any team — but anything you didn't specify, it fills in with its best guess. Oleksandr Blazheiko walks through the set of documents you hand an agent so the result is a working system, not a nice-looking prototype with the wrong logic.

Topics

  • Why an agent guesses instead of asking — and what that costs you
  • How the team's way of working shifts once an agent writes part of the code
  • Five layers of context: Brief → Functional → Non-Functional → Acceptance Criteria → Contracts
  • Acceptance criteria (Given/When/Then) — a document that is task, test, and sign-off at once
  • AGENTS.md / CLAUDE.md — the rules file an agent actually reads
  • How to verify an agent got it right, instead of just trusting "tests passed"
  • Seven common mistakes when handing work to an agent
  • A Definition of Ready checklist before launching an agent
  • How team roles shift — from a classic pipeline to a solo developer running agents
