 - Verify libraries exist before using them (check imports, package.json, etc.)
 - Use absolute file paths
 - Read files before editing them
+- Prefer symbol_search -> symbol_resolve -> read_file_range for code understanding
+- Use grep_search when you need text-pattern search rather than symbol lookup
 - Add comments sparingly - focus on "why" not "what"
 - If unclear, ask for clarification
