Most people are still debating AI models.
The smartest teams are already building AI agents.
Autonomous systems that plan, reason, remember, use tools, collaborate with other agents, and actually do the work.
That shift is happening fast, so I’ve compiled a list of foundational documents from the world’s leading AI companies, and a few builders who are deep in the trenches.
This is basically the instruction manual for the agent economy.
Here’s what you’ll find inside:
How AI moves from stateless models → autonomous agents
The real meaning of context engineering, memory, and sessions
Why MCP is becoming the USB-C of AI interoperability
How to avoid demo-ware and ship production-grade agents
The new discipline of Agent Quality & Evaluation Engineering
Proven enterprise use cases already delivering measurable & solid ROI
Why multi-agent systems beat monolithic models
What separates AI experiments from AI infrastructure
Plus, you will get instant & full access to the ultimate LLM toolkit of 100+ battle‑tested tools and frameworks, top 25 most interesting AI startups from 2025 (& their pitch decks), and the agentic AI survival guide.
If you’re building, investing, leading, or writing about AI, and you don’t understand these layers, you’re already behind.
This is the ultimate curated resource stack I wish existed earlier.
No fluff. No buzzwords. Just the documents, frameworks & playbooks shaping how AI & AI agents are actually built.
