About me

This is kitchen-engineer42.

I build the knowledge-engineering layer that sits on top of frontier agent forms, so they hold up consistently — and well — in systematically complex, 10×-context-amplified scenarios where they'd otherwise drift.

I'm aggressive about using Claude Code and other vibe-coding tools to do spec-driven development. I like whiteboard brainstorming and writing very long initial specs by hand.

I get bored fast by repetitive work. "Do it by hand → develop a feel → distill the skills → automate → package as a tool" is my working loop — every product I ship is built to replace an earlier version of me.

I built and mentor a product team of fresh graduates and ship a lot of internal tooling for them. Our products live at pdf2app.cn, now serving 5,000 users.

I like and am good at multi-threaded, constraint-heavy engineering — I can single-handedly cook a full dinner table for 15.

What I build

• John (joharnessburg) — this harness: a Claude Code plugin for knowledge-dense app building.
• KC Agent CLI — an agent purpose-built to construct production-grade document-verification systems.
• pdf2skills → Anything2Ontology — pipelines that turn professional books (and more) into agent-ready skills.
