Our AI code reviewer problem wasn't that it was wrong. It was that it wouldn't shut up
I've been thinking about a problem with AI code review that I don't see discussed enough: a reviewer can be technically correct and still make the w…
An AI's “Done” Can't Be Trusted — Quality Gates That Stop False Completion With Evidence

Code Review From the Terminal and CI, No MCP Client Required

Vim-Fu
I used to take ferocious pride in my Vim skills. I knew all the hot keys, tricks and tips. I wrote macros, memorized register mappings and even dabb…
It's Almost Like You Need an Actual Programmer
Vibe coding ain’t what it used to be. Back in the old days (2 years ago), we conjured up apps with our own programming language. Turns out, it does…
The New Technical Debt
Is AI code debt the new technical debt? As I keep learning, generating code and examining it – it’s worse. In the old days, we worked hard to create…
The Executor-Plus-Gate Pattern: Why Cheap Models Need Stronger Verification
Running LLM jobs over hundreds of items, the obvious shortcut is to collapse execution and verification into one model pass: one call, one output, s…
You Review AI Code Less Carefully Than Human Code. That Is Backwards.
Two pull requests land. A colleague wrote one by hand, and you read every line. The other came out of an AI tool, and it looks clean, consistent, an…
Three checks in our codebase that could not fail
Last night I found three checks in our own codebase that could not fail. Not checks that were failing to catch things. Checks that were structurally…
Quality Isn't Accidental — Maker/Checker Separation and Automated Validation
The Core Argument : AI agent reliability isn't achieved by "making the agent smarter" — it's achieved by the simple engineering principle of separat…
How to Review Pull Requests Without a Meeting
The PR review meeting usually starts with good intentions: reviews are stalling, so put everyone in a room and clear the queue. It works once. Then…
The checklist item that made 90 files permanently unfinished
I have a pipeline that generates document scaffolds — skeletons with blanks for a human to fill in. Every generated file looks roughly like this: &l…
Code Review Habits That Actually Stick
Why Code Reviews Matter Code reviews are one of the most effective ways to catch bugs, share knowledge, and improve code quality. But without good h…
GitHub Code Quality goes GA, and the billing meter turns on with it

Stop Using Generic AI Review. Build Your Own Board of Experts.
You finish a piece of work. You ask AI to review it. It says "looks good." You publish. It wasn't good. You had no way to know. That's the problem w…
Context Is King: Rethinking Domain Ownership, Product, and the "Spec Phase"
If you’ve spent any time recently writing detailed product requirement documents or meticulously crafting ticket specifications, you’ve probably not…
A Good AI Code Reviewer Knows When to Stay Quiet
A developer added an AI reviewer to a small Node and React project expecting an easy win. At first, the comments looked useful. Then the reviewer st…
Quality is the new Quantity
AI made writing software cheap. That is the obvious story. More code, more prototypes, more pull requests, more “I built this in one afternoon” mome…
AI is reducing quality
Once upon a time in 2018 I posted a few of my written articles to Reddit and got some replies where I was accused of "posting low quality responses…
Your AI agent's diff looks fine. That's the problem.

AI Code Generation Has a Social Media Problem

Dear Beginner Developer
