Update a contact. Required: id. Updatable: first_name, last_name, email, phone, title, fields.
AI agents use salesforce_update_contact to create or update resources in Apple Shortcuts — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Apple Shortcuts environment.
The tool creates or modifies contact data in Salesforce reversibly (updates can be undone by subsequent updates). This is characteristic of Write category. Severity is high because contact updates in a CRM could affect business-critical customer records and communication workflows, and misuse could corrupt customer data or send communications to wrong recipients.
From the tool's definition Tool description states "Update a contact" with updatable fields including first_name, last_name, email, phone, title, and custom fields. This is a modify operation on existing data.
