Writing acceptance criteria with Given/When/Then: A practical guide for AI-powered teams

Acceptance criteria define 'done.' When AI agents implement your specs, precise Given/When/Then scenarios are the difference between code that works and code that almost works.

How to write a software spec that AI agents can actually use (with template)

Most software specs are written for humans. But in 2026, your spec's most important reader is an AI agent. Here's a template and guide for writing specs that work for both.

One spec to rule them all: Why your team needs a single source of truth for AI coding

When every developer feeds their AI agent a different version of the requirements, you get different implementations. Here's why a single source of truth changes everything.

Prompt engineering is not the answer — Specs are

We've been optimizing the wrong thing. Better prompts produce marginally better code. Better specs produce fundamentally better code. Here's why the distinction matters.

Why AI-generated code has bugs — and it's not the AI's fault

AI coding agents produce buggy code not because the models are bad, but because the input is bad. The real problem is upstream: vague, incomplete, and fragmented requirements.

Vibe coding only works when you're alone — here's what breaks when teams try it

Vibe coding is the fastest way for a single developer to build something. It's also the fastest way for a team to build the wrong thing. Here's why, and what to do instead.

Human is the Bottleneck: Why the slowest part of AI-powered development is you

AI agents write code in minutes. But the human decision loop — writing specs, reviewing, approving — takes days. Here's how to identify and eliminate the bottleneck.
