AI agents call snow_get_ci_impact to retrieve information from Serac without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and analyzes impact information for a Configuration Item (CI) outage in ServiceNow. It does not create, modify, delete, or execute external operations—it only computes and returns analytical results based on existing data. This fits the 'Read' category as it queries and retrieves information with no side effects.
From the tool's definition Tool name 'snow_get_ci_impact' uses 'get_' prefix indicating retrieval/query operation. Description 'Calculate impact analysis for CI outage' describes analysis computation on existing data without modification or deletion.
