Your First Real Task

Watch a full Cowork task from handoff to deliverable: messy folder in, organized expense summary out.

The best first tasks share a shape: clear inputs (files in the folder), a clear deliverable (a file that doesn't exist yet), and criteria you can check by opening the result. Below is a replay of a classic — receipts to expense report. Notice how Claude pauses to ask one clarifying question instead of guessing, and how the final answer is a file, not a paragraph.
