Claude Code ultraplan separates thinking from doing
1. Ultraplan moves planning out of the terminal and into a browser. You get inline comments, structured review, and the ability to keep coding while the plan builds itself in the cloud. It sounds minor. It changes how you work.
Andrew Ng's career advice for AI practitioners, straight from Stanford
1. The constraint is shifting upstream. As code generation gets cheaper, the bottleneck moves from writing software to knowing what software to write. Engineers who talk to users directly are outpacing entire teams.
14 Things Anthropic Tells Claude NOT to Do, and Why You Should Steal Them as Your Own Coding Guidelines
The most useful part of Claude Code's 13,000-token system prompt isn't the identity framing or the tool descriptions. It's a section called "Doing tasks" that contains 14 explicit constraints on how code should be written.
Inside Claude Code's Prompt Architecture: What 28 Prompt Files Reveal About Building AI Coding Agents
Production-grade AI agents don't run on a single system prompt. They run on layered architectures of specialized instructions, each solving a distinct problem, composed at runtime based on context.
Your AI Coding Assistant Has a Pet: Inside Claude Code's Hidden Buddy System
Somewhere in a TypeScript codebase spanning half a million lines, an Anthropic engineer sat down and drew ASCII art of an axolotl wearing a wizard hat. Then they gave it stats.
Things I Learned from the Claude Code Source Code
The Claude Code CLI ships as a compiled binary, but the TypeScript source underneath is remarkably readable once you unpack it. I spent a week going through all 512,000 lines across 1,884 files, looking for the engineering decisions that reveal where
