Agentic coding is a transformative new reality. Human engineers must provide coding rules, workflow descriptions, and a keen eye to make sure our agents code at our level or even better. It’s also important, however, to be smart about how we add new features to our apps. Piling more specifications on top of an already bloated agent context is likely to result in costly hallucinations. Come to this talk to learn how to create simple and self-updating behavioral specs using existing Test Driven Development (TDD) techniques, including Gherkin syntax and Snapshot testing. We’ll wrap it all up with a demonstration of this process using OpenSpec - THE emerging industry standard for Spec Driven Development! Vibe smart, not hard!
