VS Code Integration Patterns

Claude Code in VS Code is not a replacement for the terminal. It is a complement. The terminal gives you raw power — full context control, MCP management, parallel instances, and hooks. VS Code gives you something the terminal cannot: visual context. You can see the file tree, the editor contents, the terminal output, and the Claude conversation side by side. For certain workflows, that visual context is worth more than the terminal's flexibility.

The integration works through the Claude Code extension, which embeds a Claude panel directly in the VS Code sidebar. It reads the same CLAUDE.md files, respects the same settings.json permissions, and connects to the same MCP servers as the terminal. The key difference is input ergonomics: you can select code in the editor and send it to Claude with a keyboard shortcut. No copy-paste, no file path references, no "read lines 45-80 of src/utils/parser.ts." You highlight, you send, Claude sees exactly what you see.

This selection-based workflow is particularly powerful for code review, refactoring, and debugging. Select a function, ask "what are the edge cases this function does not handle?" Select a test file, ask "what scenarios are missing?" Select an error message in the terminal, ask "what is causing this and how do I fix it?" Each interaction starts from a visual selection that gives Claude precise, unambiguous context.
