Ultrareview: Bug Hunting in the Cloud
Shipped alongside Claude Opus 4.7, /ultrareview is the heavyweight cousin of the /review command we already covered.

Awesome AI for Delphi — a curated GitHub list
I just published a new GitHub repository: Awesome-AI-For-Delphi. It is a curated list of tools, libraries, MCP servers, and resources for using AI with Delphi.

The Science Behind CLAUDE.md: What the Research Says
The Controversy In early 2026, two independent research teams published the first empirical studies on whether CLAUDE.md-style instruction files actually improve AI coding performance. Their headlines seemed to tell different stories — one modest, one dramatic. Tech blogs promptly cherry-picked the modest one and ran with it. An article on XDA Developers declared that CLAUDE.md

Trying out Claude Code for Delphi
Using Claude Code for Delphi — What I Learned Writing a Book About It What started as a frustrated blog post became a 280-page book. Here’s the story. In early 2026, a post on Delphipraxis claimed that one hour of development with Claude Code was worth a full day of solo programming. Bold claim. I
