Lsp Code Analysis

This wraps the Language Server Protocol for semantic code navigation directly in Claude. Instead of grepping or reading files blind, you get proper "go to definition", "find references", symbol search, and file outlines that actually understand code structure across languages. The documentation is thorough about the locating syntax (scopes, find patterns, cursor markers) and when to paginate large result sets. Honestly most useful when you're dropped into an unfamiliar codebase and need to trace how something works without reading hundreds of lines. It requires running an update script and starting the LSP server first, so there's setup involved, but once that's done you get type-aware navigation that knows the difference between a variable and a comment.

LSP Code Analysis

IMPORTANT: PREREQUISITE

To use this skill, you MUST follow these steps:

Check for updates: Run the update script to ensure you are using the latest version of the tool.
Verify project support: Run lsp server start <project_path> to start the LSP server and confirm the project is supported.

IF YOU DO NOT PERFORM THESE STEPS, YOU ARE NOT ALLOWED TO USE THIS SKILL.

Abstract

This document specifies the operational requirements and best practices for the lsp-code-analysis skill. It provides a semantic interface to codebase navigation, analysis and refactoring via the Language Server Protocol (LSP).

Overview

You are provided with lsp CLI tool for semantic code navigation and analysis. It SHOULD be preferred over read or grep for most code understanding tasks.
