Short, technical dispatches on agentic PDLC, platforms and AI systems. From real work, not theory.
Every agent demo works. Day two is where they fall over. The five layers of harness engineering, the system around the model, that decide whether an agent survives production.
Most agents are bad at using tools because the tools were built for programmers, not for a model reading a one-line description under load. How to design tools, and MCP servers, that agents get right.
Teams reach for a vector DB and stop thinking. Real agents need layered memory: a working set, durable preferences, retrieval, and state that survives a restart. A practical breakdown.
