Blast Radius for ServiceNow
Blast Radius provides configuration dependency analysis across a ServiceNow instance. Before making changes to fields, tables, or artifacts, use these tools to understand the full blast radius.
Tool Overview
| Tool | Purpose | When to Use |
|---|---|---|
snow_blast_radius_apps |
List apps with config counts | Starting point — understand the instance landscape |
snow_blast_radius_table_configs |
All configs on a table | "What runs on the incident table?" |
snow_blast_radius_field_references |
Reverse field lookup | "What touches incident.assignment_group?" |
snow_blast_radius_artifact_dependencies |
Forward dependency analysis | "What does this business rule read/write?" |
snow_blast_radius_dependents |
Find what uses / calls an artifact (deep 3-phase scan, 100+ tables) | "What calls IncidentUtils?" / "Can I safely delete this business rule?" |
snow_code_search |
Substring search across every script-bearing table (business rules, script includes, client scripts, widgets, scripted REST ops, UI actions, ACLs, notifications, UX scripts, …) | "Where is IncidentUtils.resolve referenced anywhere?" — use when reverse-dependency tools don't index what you need |
Coverage
snow_blast_radius_field_references and snow_blast_radius_table_configs scan the following artifact types in parallel. Types backed by plugins that are not activated on the instance fail silently — the tool reports them under errors_by_type and continues.
