Why these resources exist

I've shipped 109 production AI systems for clients across e-commerce, healthcare, real estate, and B2B SaaS. Most online content about AI agents is vendor marketing or theoretical. These resources are the things I wish existed when I was building. If they save you a week of dead ends, the time spent writing them was worth it.
