CLAUDE CODE 101, FOR DESIGNERS

Summary from the TLDR Design newsletter

Claude Code extends Anthropic's Claude beyond chat into a terminal tool that can create, edit, and run files, building full apps rather than just describing prototypes. Key concepts include context windows and tokens (its working memory), sessions (single continuous workstreams), CLAUDE.md (a standing project brief), approval modes, commands, skills, agents, and MCP (a connector standard linking Claude to outside tools). This piece is the first in a series aimed at helping product designers transition to using Claude Code, focusing purely on defining the surrounding jargon.
