Every test suite has the same dirty secret: name="Test User", email="test@test.com", bio="Lorem ipsum". Copy-pasted across 50 tests, never catching real edge cases, never feeling like production data. I built FixtureForge to fix this — but along the way, I learned that AI is the wrong tool for most...

It is rather amusing to me that this is the sum total of a prompt needed to get Claude Code to take a task from my task system, find the code, look at the production database, debug the problem, propose a solution, update task status for review, test it, and push the fix to production.

The Invisible Orchestrator: Cheap Routing + Expensive Reasoning in Multi-Agent Apps

The Problem We had four specialist AI agents — math, verbal, data insights, and strategy — each with a different system prompt, RAG namespace, and reasoning style. Every user message needed to land on the right one. The naive solution: run every message through GPT-4o, ask it to decide...

Everyone's Using AI. No One Agrees How.

I got a DM from a principal engineer last week. He's spending more than $2,000 a month on AI tokens. Not because he's lazy. Because he's figured something out. The tool isn't giving him 10x output. It's giving him exponential output. He's orchestrating agents, chaining workflows, building systems th...
