-WHEN TO USE:
-- Calling 2+ different tool types together (e.g., read_file + search_file_content + glob)
-- Performing 3+ independent operations of the same type
-- Gathering information from multiple sources at once
+Use this tool ONLY when you need to perform 5+ truly independent operations that have no sequential dependencies. For most cases, prefer individual tool calls in sequence.
 
-WHY USE BATCH:
-- JSON format is simpler and less error-prone than nested XML tool calls
-- Clearly expresses "these operations are a group"
-- Reduces cognitive load when generating multiple tool calls
+AVOID using batch for:
+- Operations with dependencies (one result feeds into another)
+- File edits followed by testing/validation
+- Less than 5 independent operations
+- Different tool types that may need result inspection between calls
 
-Example: To read a file, search for a pattern, and list files:
