WHAT IT DOES

What create_playbook does on NowAIKit — ServiceNow AI Toolkit

AI agents use create_playbook to create or update resources in NowAIKit — ServiceNow AI Toolkit, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your NowAIKit — ServiceNow AI Toolkit environment.

RISK

Why create_playbook is rated Medium

This tool creates (not reads or executes directly) playbook definitions—a reversible write operation. While high severity due to potential for misuse in orchestrating downstream ServiceNow actions, it does not irreversibly delete data (Destructive), move money (Financial), or directly execute arbitrary code (Execute).

From the tool's definition Tool name 'create_playbook' and description phrase 'Create a playbook definition' indicate creation of new data/configuration. Requirement for 'WRITE_ENABLED' permission confirms write-class operation.
