UnityRAG

What it does

Tools

• search: Search through the indexed Unity documentation.
• resolve_symbol: Find specific symbols within the documentation.
• open: Open a specific documentation page.
• related: Find documentation related to a specific topic.
• list_files: List available documentation files.
• status: Check the current status of the RAG index and configuration.
