A conversation. You type, Claude replies. Web search, code execution, artefacts (HTML, MD, charts, docs). No filesystem access.
Tasks that need to read or write across many files on your computer, or that should run unattended for 10+ minutes.
A delegated coworker. Reads scoped folders on your machine, runs multi-step tasks, scheduled jobs, uses plugins & skills, hands back a finished deliverable.
Quick questions, one-off drafts, or anything you'd babysit turn-by-turn. If you're not delegating, you've picked the wrong surface.
A terminal-based engineering assistant. Reads codebases, edits files in place, runs tests, executes shell commands, works against git. Install: npm i -g @anthropic-ai/claude-code
Knowledge work, docs, briefs, or anything Cowork could handle. Most expensive surface — easiest to burn limits.
