- Claude Code currently uses text search tools like Grep, Glob, and Read for code navigation, which is slow and imprecise.
- LSP (Language Server Protocol) enables semantic code intelligence, providing exact definitions and references in milliseconds.
- LSP offers passive benefits like automatic error correction and active features like go-to-definition, find-references, and type information.
- Setting up LSP involves enabling a feature flag, installing language servers, and configuring plugins in Claude Code.
- LSP significantly improves Claude Code's performance, reducing query times from 30-60 seconds to ~50ms.
- Common issues include plugins not being enabled, language servers not installed, or startup race conditions.
- Explicit instructions can ensure Claude Code prefers LSP over text search for code navigation tasks.
