Claude Cowork — Quick Guide
Claude Cowork
Delegation over Conversation — describe outcome, get finished file.
Cowork is the same agent as Claude Code, built for knowledge workers who don't use command line. Instead of chat replies, it produces real files (.pptx, .docx, .xlsx) saved directly to your drive.
Chat vs Cowork — When to Switch
| Use Chat when | Use Cowork when |
|---|---|
| Quick Q&A, drafting text | Task needs to read/write actual files |
| One-turn exchange | Multi-step, runs 5–30 min |
| No file output needed | Output is a real file on your machine |
| Connects to Gmail, Slack, Drive, browser |
How to Implement
- Open Claude Desktop → click the Cowork tab
- Click "Work in a folder" → select your working folder → "Always allow"
- Write your brief using the I-T-O formula
- Answer Claude's clarifying questions → approve the plan → let it run
- Monitor the progress panel — steer mid-run if needed
- Open the finished file, run your 3-step review
The I-T-O Prompt Formula
Every Cowork brief needs 3 things:
- I — Input: Where is the source data? (folder, file name, Slack channel)
- T — Transformation: What should Claude do with it?
- O — Output: What does "done" look like? (format, filename, save location)
❌ "Clean up my files"
✅ Input: My /Downloads folder
Transformation: Sort files by type into dated subfolders
Output: Organized subfolders, saved in /Downloads
Key rule: Describe the outcome — don't list steps. When you micromanage steps, you block Claude's planning ability and lose the leverage you're paying for.
Scheduled Tasks — Full Automation
Combine Skills + Schedules to build a background automation engine:
- Type
/schedulein any Cowork chat - Set cadence: hourly / daily / weekly / monthly
- Define folder, output format, approval gate
Example:
"Every Friday 4pm: pull Slack #sales messages from the week,
extract key deal updates, draft summary email to leadership.
Draft only — don't send."
Critical limitation: Cowork only runs when your computer is on and the Claude Desktop app is open. Laptop asleep = task doesn't run.
Effectiveness
- You stay in control at 3 points: review the plan before, steer during, review output after
- Always default to "Draft only — don't send" for emails and actions with real-world impact
- 3-step review habit after every run: (1) open the file, (2) check one number, (3) follow one logic thread
- Output looks polished even when wrong — polished ≠ correct
