+# GlideRecord Bulk Delete with Safety Checks
+
+## Description
+This snippet allows you to safely delete multiple records from a ServiceNow table based on an encoded query.
+It logs all records that match the query so you can review them before actually deleting anything.  
+Helps prevent accidental mass deletion of important data.
+
+## Note 
+- Works in Global Scope by default
+- Can be executed in Background Scripts or Script Includes
+- **ALWAYS REVIEW LOGS BEFORE ENABLING DELETION**
+## Prerequisites
+- Server-side context (Background Script, Business Rule, Script Include)
+- Access to the target table
+- Basic understanding of GlideRecord and Encoded Queries
+
+## Usage
+```javascript
+// Logs all active low-priority incidents that would be deleted
+safeDelete('incident', 'active=true^priority=5');
+
+// To perform actual deletion, uncomment gr.deleteRecord() inside the function
+```
+
+## Output
+```
+Records matching query: 3
+Record sys_id: 12345abcdef would be deleted.
+Record sys_id: 23456bcdef would be deleted.
+Record sys_id: 34567cdefg would be deleted.
+Bulk delete preview complete. Verify logs before enabling deletion.
+```
