WHAT IT DOES

What create_lead does on Lawruler

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

WHY IT NEEDS A POLICY

Why create_lead needs a policy

This tool creates new records in a legal CRM, which is a reversible write operation (records can be edited or deleted later). It does not execute code, delete data irreversibly, or move money. The medium severity reflects the potential for spam/bogus lead creation or misuse to pollute the CRM database, but the impact is limited since leads can be managed afterward.

From the tool's definition Tool description states 'Create a new lead/intake' — this creates new data in the LawRuler CRM system. Required fields (FirstName+LastName or FullName) and strongly recommended fields (CellPhone, Email) indicate persistent data entry.
