WHAT IT DOES

What lithtrix_passport_sponsor does on Lithtrix

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

WHY IT NEEDS A POLICY

Why lithtrix_passport_sponsor needs a policy

This tool creates a sponsorship/vouching relationship between two agents via a POST request. It modifies state by establishing a trust relationship (sponsoring a ward), which is reversible (there is a sibling revoke tool: lithtrix_agent_vouch_revoke). Since it writes/creates a relationship record rather than deleting or executing code, Write is the appropriate category.

From the tool's definition POST /v1/agents/{sponsor_id}/sponsor/{ward_id} — vouch for ward (Bearer must match sponsor_id)
