Get Loopy! Act, React, Iterate Until We Love It

7/21/2026

An agent is a week into rewriting my memory system's retrieval code. It built a deterministic scorer, ran dozens of experiments, kept the good ideas and ditched the failed ones, all from one prompt I wrote at the start. Loop engineering is the third act of agentic engineering: the agent acts, observes the result, feeds it back into its own context, and goes again until the goal is true. Here's two years of building these loops, with receipts.

This is the operating system I built underneath the prompts: a contract, a library of skills, and a knowledge graph that survives every session. Plus enough of the anatomy that you can build your own.
