You now have two Claude interfaces: Claude Code (terminal-based) and Claude Cowork (desktop-based). Both run on the same Claude Agent SDK. Both support Skills. Both provide agentic AI capabilities. So which do you use, and when?
This lesson provides a decision framework.
Simple rule: Code for code, Cowork for documents.
For any task, evaluate these criteria:
Tasks:
Interface choice: Claude Code for everything except maybe the documentation.
Workflow:
Why: Code is optimized for software development. The terminal integration, git support, and code-aware capabilities make development more efficient.
Tasks:
Interface choice: Claude Cowork throughout.
Workflow:
Why: Cowork's document Skills and Connector integration are purpose-built for this workflow.
Tasks:
Interface choice: Hybrid approach.
Workflow:
Why: Development work in Code, documentation/distribution in Cowork. Each interface handles what it's optimized for.
Some workflows naturally span both interfaces. Recognize these patterns:
Key insight: The interfaces aren't competitors—they're tools for different parts of the same workflow.
A critical point: Skills you create work in both interfaces.
If you create a Skill for "financial report analysis," you can:
The Skill encodes expertise. The interface provides the mechanism. This separation means your expertise investments transfer across contexts.
Looking forward, Code and Cowork will converge:
Current state: Two separate interfaces optimized for different use cases.
Coming: Unified interface where you can:
Implication: Don't invest heavily in learning interface-specific patterns that won't transfer. Focus on:
The mental models you're learning will outlast any specific interface.
If you're a developer:
If you're a knowledge worker:
If you wear both hats:
Don't overthink the decision. The interfaces share:
The differences are:
Start with the simple rule: Code for code, Cowork for documents. Refine from there based on your experience. As the interfaces converge, this decision will become less important anyway.
**🔍 Analyze Your Work:"
"Review the tasks I've done this week. Categorize them: Which would have been better in Claude Code? Which in Claude Cowork? Which would benefit from using both? Create a personal decision guide."
What you're learning: Personal workflow analysis—understanding your own patterns and which tools optimize them. Self-awareness about your work makes tool selection automatic.
**💡 Design a Hybrid Workflow:"
"Think of a project I'm working on. Design a workflow that uses both Claude Code and Claude Cowork. Where would I switch between interfaces? What would each handle? Why is this split optimal?"
What you're learning: Workflow design—thinking through how to combine tools effectively. The best workflows use each tool for what it's best at.
**🏗️ Create Portable Skills:"
"Design a Skill for my domain that would work well in both Claude Code and Claude Cowork. What expertise should it encode? How would I use it differently in each interface? Write the SKILL.md."
What you're learning: Skill portability—creating expertise that transfers across contexts. This investment pays off in both interfaces today and in the unified interface of tomorrow.
You've completed the Cowork content. The remaining lessons cover the business side—how to monetize your Skills (Lesson 32) and a chapter quiz (Lesson 34) that tests your understanding of both Claude Code and Claude Cowork.
Simple rule: Code for code, Cowork for documents.
Pattern 1: Development + Documentation
Pattern 2: Analysis + Presentation
Pattern 3: Script + Distribution
Skills you create work in both interfaces. A Skill for "financial report analysis" can be used in:
Current: Two separate interfaces optimized for different use cases
Coming: Unified interface with terminal/desktop switching, shared Skills, unified settings
Implication: Focus on patterns that transfer (agentic reasoning, Skill design), not interface-specific tricks.
