List saved contacts.
AI agents call keyid_list_contacts to retrieve information from KeyID Agent Kit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns a list of existing contacts without creating, modifying, deleting, or executing any actions. It is a read-only operation with minimal security risk—exposure would allow viewing contact information but not altering it or performing external actions. The blast radius is limited to information disclosure of contact metadata.
From the tool's definition Tool name 'keyid_list_contacts' and description 'List saved contacts' indicate a retrieval operation with no modification or side effects.
