AI agents call cja_validate_segment to retrieve information from Adobe Cja without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Validation operations are non-destructive checks that query or verify configuration without side effects. The tool appears to inspect segment validity rather than create, modify, or delete segments (those capabilities exist as separate tools: cja_create_segment, cja_get_segment_details).
From the tool's definition Tool name 'cja_validate_segment' and context within Adobe CJA analytics server. The 'validate' operation suggests checking segment syntax or rules without modifying data.
