Lesson 1.2 of the Free Claude Cowork Course · 20 minutes
Overview
The single biggest skill in this course isn’t technical — it’s briefing. Cowork does its best work when you describe the outcome you want, not a sequence of micro-instructions. This lesson teaches the three-part brief that experienced users rely on, and you’ll use it to complete your first genuinely useful task.
What You’ll Do
- Learn the outcome-inputs-format briefing pattern
- Compare a vague instruction against a good brief on the same task, and see the quality gap
- Complete one real task from a scenario matched to your kind of job
The Lesson
Say “start lesson 1.2” with the course folder open. The lesson introduces the brief structure: outcome (“a one-page summary I can send to a client”), inputs (“using the three documents in the project folder”), and format (“as a Word document, with headings, under 400 words”). You’ll run the same task twice — once with a lazy one-liner, once with a proper brief — and compare the results side by side. The difference does more to convince people than any explanation.
Then you’ll pick a scenario that matches your actual work — the course folder includes several, from operations to client services — and complete it start to finish with your own brief.
Try It Now
Write a three-part brief for a task from your real job — don’t run it yet, just write it. You’ll use it as raw material in later lessons, and by lesson 2.5 it may become your capstone workflow.
