Generate a repository map showing the most relevant code symbols (functions, classes, methods) based on AST analysis and PageRank ranking.

This tool analyzes the codebase structure using Tree-sitter AST parsing and ranks symbols by their relevance using the PageRank algorithm. It helps AI understand the code structure by showing:
- Important function and class definitions
- Their relationships through references
- Prioritized by relevance to the current context

Parameters:
- directory: Directory to analyze (default: current working directory)
- chat_files: Files currently being discussed (excluded from map output)
- mentioned_files: File names mentioned in conversation (boost relevance)
- mentioned_identifiers: Symbol names mentioned (boost relevance)
- max_tokens: Maximum output token count (default: 1024)

The output shows relevant code symbols organized by file, helping to understand:
- What functions/classes exist in the codebase
- How different parts of the code relate to each other
- Which symbols are most important based on usage patterns

Use this tool when you need to understand the overall structure of a codebase or find relevant code locations for a task.
