Who Will Use Claude Notes?
How to Use Claude Notes
- 1Install the Claude Code 2.0 terminal package.
- 2Add the native VS Code extension from the Marketplace for IDE integration.
- 3Start a session; the AI will generate code, automatically create checkpoints, and run hooks as configured.
- 4Use subagents to delegate parallel tasks such as backend API generation while the main agent works on frontend code.
- 5Leverage background tasks to keep dev servers or long‑running processes active without blocking the main workflow.
- 6Switch models or adjust settings with the /model command as needed.
Pros & Cons

Frequently Asked Questions
What is Claude Code 2.0?
Claude Code 2.0 is an advanced AI development tool that works in your terminal and IDE, powered by Sonnet 4.5. It features autonomous operation through subagents, hooks, checkpoints, and background tasks for handling complex development workflows.
What are the key new features in Claude Code 2.0?
Claude Code 2.0 introduces a native VS Code extension, an enhanced terminal interface with searchable history, automatic checkpoints for safe exploration, subagents for parallel workflows, hooks for automated actions, and background tasks for long‑running processes.
How do checkpoints work?
Checkpoints automatically save your code state before each change made by Claude. You can instantly rewind to previous versions by tapping Esc twice or using the /rewind command. When rewinding, you can restore the code, conversation, or both to a prior state.
What are subagents and how do they help?
Subagents are specialized agents that handle specific tasks in parallel. For example, one subagent can build a backend API while the main agent works on the frontend, enabling efficient parallel development workflows.
What is the Claude Agent SDK?
The Claude Agent SDK (formerly Claude Code SDK) provides access to the core tools, context management systems, and permissions frameworks that power Claude Code. It allows teams to create custom agentic experiences for specific workflows, including support for subagents and hooks.
How do I get started with Claude Code 2.0?
Download the VS Code extension from the VS Code Extension Marketplace for IDE integration, or update your terminal installation for the latest features. Sonnet 4.5 is the default model, but you can switch models using the /model command.
