Claude Was Coding Blind Until This

Ever wondered how VS Code instantly finds every reference to a function across thousands of files? That's Language Server Protocol (LSP) — and Claude Code finally has it built in. In this video, I show you: → Why regular search returns noisy, false-positive results → How to set up LSP with a simple plugin install → The difference between grep-style search vs LSP precision → How Claude Code can now read actual SDK type definitions This is a game-changer for anyone working with large codebases. 🔗 RESOURCES Claude Code LSP Docs: https://code.claude.com/docs/en/plugins-reference Official Plugin Marketplace: https://github.com/anthropics/claude-plugins-official Pyright (Python LSP): https://github.com/microsoft/pyright 📋 SUPPORTED LANGUAGES - Python (Pyright) - TypeScript/JavaScript - Go (gopls) - Rust (rust-analyzer) - C# (csharp-ls) - And more in the marketplace ⏱️ TIMESTAMPS 0:00 - What is LSP and why it matters 0:50 - The problem: grep returns noise 1:40 - Setting up Pyright LSP 2:20 - The solution: precise results 3:09 - Bonus: SDK parameter lookup 4:05 - Why this changes everything ⚠️ VERSION NOTE Make sure you're on Claude Code 2.1.0 or higher.
