Do I need to build the code index manually?

Yes, you should run `mcp__unity-mcp-server__build_index()` during your first session or when the index is outdated to ensure accurate symbol searching and navigation.

What is a 'namePath' in this context?

A namePath is a hierarchical identifier (e.g., PlayerController/TakeDamage) used to precisely target classes, methods, or fields within your script files.

Does it support Unity Unit Testing?

Absolutely. It includes dedicated workflows for creating NUnit test classes, adding test methods, and verifying implementation through a TDD cycle.

How does the 80-character rule work?

The 80-character rule helps you choose the right tool: use `edit_snippet` for minor 1-2 line changes under 80 characters, and `edit_structured` for larger changes like replacing entire method bodies.

Can this skill handle project-wide renaming?

Yes, the `rename_symbol` tool allows you to preview and apply renames across the entire project scope, ensuring all references are updated.

Game Development

Optimizes Unity C# script editing, refactoring, and symbol navigation using an integrated LSP and efficient TDD workflows.

This skill provides an advanced interface for managing Unity C# scripts by leveraging a specialized Model Context Protocol (MCP) server that delivers high-density code context to Claude. It streamlines common game development tasks such as method body replacement, class creation, and project-wide symbol renaming while adhering to specific editing rules to maintain code integrity. By providing 5x more compact output than standard tools, it maximizes Claude's context window efficiency, making it ideal for developers who want to automate boilerplate, manage complex refactors, and implement Red-Green-Refactor TDD cycles directly within their AI coding environment.
