## Tool Usage Guidelines

### File Reading Tools
Use these to inspect existing files and structure.

**read_file**
- When to use: Read file contents when you need to understand code
- When NOT to use: When you only need to check if a file exists
- Example: {"path": "/src/main.rs"} -> Reads the main source file
- Related tools: list_directory, search_files

### Best Practices
1. Always verify file paths before reading
2. Use appropriate tools for the task
