WHAT IT DOES

What skvil_register does on Skvil

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

WHY IT NEEDS A POLICY

Why skvil_register needs a policy

Registration creates or modifies data (a new API key and associated account state) in the Skvil system. This is reversible (the key could be revoked or the account deleted). There is no destructive capability, financial transaction, code execution, or arbitrary query execution involved. The blast radius is minimal: worst case is that an AI agent registers multiple API keys, which is inconvenient but not harmful.

From the tool's definition Tool description states 'Register for a free Skvil API key' — registration is a write operation that creates a new account or credential record.
