I Built a Code Review Agent That Remembers What It Found
I wanted CodeMind to work differently: remember useful lessons from previous reviews and use them when reviewing code again. That idea became CodeMi…
KVCODERS: The subtle bug in comparing Python output as text
KVCoders has an "Output Practice" mode where students see a Python (or SQL) snippet and have to predict its exact printed output — a real, common CB…
The Validation Rule That Was Itself Invalid
I lost a save cycle last week to a bug that I now think is one of the most under-discussed failure modes in configurable systems: a validation rule…
Production repository conventions for AI coding agents: a working contract
Production repository conventions for AI coding agents are a working contract between the codebase and the person or agent changing it. They answer…
A Minimal-Context Take-Home Test for AI Code Reviewers: When More History Hurts
Recent discussions about AI assistants that trust every archived comment raise a practical question for engineering teams: does an AI code reviewer…
An AI's “Done” Can't Be Trusted — Quality Gates That Stop False Completion With Evidence
On June 29, 2026, a mobile app reported that "the first wave of parity with the PC version is complete, 162 tests green." When we actually touched i…
Comprehension debt: what AI-written code actually costs
Originally published at fathohm.dev . The term "comprehension debt" is Jason Gorman's, from September 2025, carried by Addy Osmani in March 2026 — t…
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…
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…
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
You know that "GA" line in a changelog that you skim past, until a month later Finance emails asking why the invoice grew? This one shipped with the…
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…
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…
Your AI agent's diff looks fine. That's the problem.
Give an agent a simple task: Add an optional loyalty discount to retail pricing. Enterprise pricing and the public API must stay unchanged. Twenty m…
AI Code Generation Has a Social Media Problem
The morning I announced what I'd been building, a comment showed up on the post. It was friendly. It opened with a compliment, agreed with me, and t…
When Your Codebase Starts Slowing You Down...
Every developer knows the feeling. You open a ticket that looks simple. A small change. Maybe one endpoint, one validation rule, one extra field. Th…
When Code Takes a Break: What Engineers Think About on Silent Days
📌 Overview Today was a "silent day" — no Claude Code sessions, no commits, no code changes. Yet technical work isn't just about writing code. This d…
How To Measure AI Token Debt In A Real Codebase
AI token debt is the extra AI-agent context, repository search, inference, retry, and validation work created when a codebase is hard to reason abou…
"It Works" Has Never Been Good Enough
It all started when the Senior Architect dropped by the daily standup. The team lead had the backlog up on the big screen and there was a story abou…
Your AI Agent Writes Code With Hidden Debt. Here's How I Force It to Audit Itself.
Companies are spending 44% of their AI tokens fixing bugs that AI generated (Entelligence AI, May 2026). CodeRabbit analyzed open-source PRs and fou…
The Role of QA in the New AI SDLC
QA’s role in the new AI SDLC is no longer just “test the finished application.” It is becoming quality engineering across the entire lifecycle : Req…
Securing AI Generated Code: You Ship It, You Own It
A developer merges a pull request on Friday afternoon. Monday morning, a security review flags a SQL injection flaw in a new endpoint. When you ask…

Lessons from three months of vibe coding (and a complexity score of 53)
TL;DR — I spent three months vibe-coding a side project with an AI agent. It felt fast and productive until I opened a file and saw 3000 lines, func…
Senior Developers: Experts in Code, But What About Communication?
We’ve all been there: a senior developer confidently expounds on their expertise, yet the codebase seems to have a mind of its own. Sometimes, it's…
"Prime Testable" Code
What is the EASIEST Python code to test? Because writing unit tests is a superpower. It's great. Completely changes what you are capable of as a dev…
200 Lines in CLAUDE.md Dropped My Code Quality to 79% — Splitting into 3 Files Got It to 96.9%
