This skill provides symbol-level code understanding and navigation using Language Server Protocol (LSP). Enables IDE-like capabilities for finding symbols, tracking references, and making precise code edits at the symbol level.

TL;DR

Provides symbol-level code navigation and editing via LSP. Enables IDE-like semantic understanding for precise code navigation and refactoring.

What Is It

Symbol-level code understanding using LSP
IDE-like capabilities for finding and tracking code symbols
Precise code edits at symbol locations
Supports 30+ languages via language servers

Key Features

Find symbols by name and type (class, function, variable)
Track all references and usages of a symbol
Precise insertion before/after symbol definitions
Renaming symbols with full reference updates
Understands code semantics, not just text patterns
Supports 30+ languages including Python, JS, Rust, Go, Java, C++

How to Use

1.Use `find_symbol` to locate symbol definitions
2.Use `find_referencing_symbols` to track all usages
3.Use `insert_after_symbol` or `insert_before_symbol` for precise edits
4.Access via MCP tools or CLI command
5.Prefers direct MCP tools for better integration

Guardrails & Gotchas

Use file-search (ripgrep/ast-grep) for text pattern matching
Avoid symbol-level precision when speed and simplicity are needed
Ensure LSP server is available for language support
Never use symbol-level tools for simple string or comment searches
