What problem does it solve?

This Skill provides advanced, token-efficient code analysis and editing capabilities, allowing developers to interact with codebases at a symbolic level rather than file-by-file. It eliminates the need for manual file navigation and full file reads, significantly reducing context window usage and speeding up complex refactoring and code understanding tasks.

Core Features & Use Cases

• Symbol-Level Interaction: Search, find, and replace code based on symbols (classes, functions, variables) rather than raw text.
• Dependency Analysis: Quickly identify where a specific symbol is referenced, understanding its impact across the codebase.
• Efficient Code Modification: Insert code before/after symbols or replace entire symbol bodies with high precision and token efficiency.
• Use Case: When refactoring a large UserService class, use this Skill to find all references to a specific createUser method, analyze its dependencies, and then safely modify its implementation without reading the entire file.

Quick Start

Activate the Serena project in the current directory, then get an overview of symbols in 'src/main.ts'.
