Code Studio is a Claude plugin that turns your AI assistant into a dedicated coding pair programmer. Three skills: • Explain: adapts code breakdowns to your experience level • Refactor: cleaned-up code with annotated reasoning for every change; never silently alters behaviour • Document: inline comments, docstrings, and READMEs in the right format per language No extra setup needed — just install and start coding. Works in Claude Cowork (desktop) and Claude Code (CLI).
