Loop Engineering
Stop writing prompts. Start building agent loops. A Claude Code skill for self-running loops that keep going until a real, testable goal is met.
The gate is mechanical — a Stop hook that runs the actual test suite and costs zero tokens — so the agent can never approve its own half-finished work. Watch the koi: when it fails at VERIFY, it goes back to EXECUTE. That is the whole idea.
“The maker can’t be the judge.”

Inside the index
Every chunk is a point in here.
Retrieval is a geometry problem before it is a language problem. Real clusters, a query moving through them, and the six nearest neighbours lighting up as it passes.
This is what a retrieval bug looks like from the inside. When the wrong cluster lights up, no amount of prompt engineering downstream will save the answer.
Knowledge · agents
A vault that keeps writing itself.
An LLM agent reads new sources, integrates them into existing pages, updates the entity notes, flags its own contradictions and keeps the cross-references intact. I find the sources. It does the bookkeeping.
Hover a node — its neighbourhood lights up. That is a retrieval scope, not a decoration.

Writing.
Technical writing when I have something worth saying. Not a newsletter. Not a content strategy.
