List campaigns with summary stats. Optionally filter by status.
AI agents call crow_campaign_list to retrieve information from Crow without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays campaign information with optional filtering—a read-only operation. There are no side effects, data modifications, code execution, or destructive actions. The blast radius of misuse is minimal, as an AI agent could only retrieve campaign metadata it may not have authorization to see, not modify or delete anything.
From the tool's definition Tool name 'crow_campaign_list' and description 'List campaigns with summary stats. Optionally filter by status' indicate a query/retrieval operation with no modification or deletion of data.

"crow_campaign_list": {}
}
