Agents, Ontologies and the Path to Trusted AI
Agents, Ontologies and the Path to Trusted AI
Five layers, each answering a different question:
Agentic Plumbing — can I run it? Command line, Linux, virtual environments, Git and GitHub, and choosing between frontier APIs and models on your own hardware. The ground every agent stands on, and where most people quietly get stuck.
Foundations — why does it work? From Cajal's neurons to transformers. How embeddings turn meaning into geometry, how RAG grounds a model in your documents, and why "nearest" is not the same as "correct."
Agentic AI — how do I build it? Twelve lessons on the working parts of a real agent: prompt and context engineering, context windows, the KV-cache and prompt caching, tool loops, workflows versus autonomous agents, memory and MCP. Then the part most courses skip — guardrails, the AI safety trifecta, and how to evaluate what your agent actually does.
Ontologies — how do I keep it right? Agents fail in a particular way: fluently, plausibly, wrong. Model your domain in RDF, RDFS and OWL, query it with SPARQL, and write SHACL shapes that check an action before it happens. The same standards behind SNOMED CT and FIBO.
MAKE Labs — can I prove it? Eight hands-on exercises where you measure instead of guess: prompt testing, chain-of-thought, long-context recall, structured extraction, model cost and speed, sub-agent architectures, cache strategy. Each one ends as a GitHub artifact you can show.
Go in order, or jump in. Every lesson stands on its own. At home in the terminal? Start at Agentic AI. Agent works but you can't trust it? Go straight to Ontologies. The sequence follows the five domains of Anthropic's Claude Certified Architect exam, so it lines up with that credential — but the goal is the skill, not the badge.
