The AI Knowledge Layer: 127 Pages, Zero Vector Databases, and What We Got Wrong
Karpathy's LLM wiki gist hit 99,000 bookmarks in a week. It resonated because it named what every AI user feels: your agents have no memory. We run a knowledge layer in production. Here is what works, what does not, and how to build one in 20 minutes.
Every SaaS Becomes an Agent Harness
A sales team replaced an entire sales SaaS with one Claude skill and three MCP servers. This is not an edge case. It's the pattern that will define which software categories survive 2026.
From Rules to Results: What 22K Stars on a Single CLAUDE.md Reveal About AI-Assisted Development
The karpathy-skills repo proves that AI coding bottlenecks aren't about model capability. They're about the behavioral contract between human and LLM.
Vibe Coding Is a Trap - Why AI-Built Software Still Needs Engineers
Andrej Karpathy coined "vibe coding" in February 2025. Since then, a wave of AI-generated apps has shipped that work in demos and break in production. The problem is not the AI tools - it is using them without engineering discipline.
Anti-Slop Content Strategy: Why LLMs Won't Cite What They Can Already Generate
If ChatGPT can write your article from the title alone, it won't cite it either. Here's the content framework that optimizes for LLM citations instead of backlinks.
AI Agents Are Replacing Entire SaaS Products. Your Subscriptions Are a Legacy Tax.
