WHAT IT DOES

What scf_create_risk does on Scf

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

WHY IT NEEDS A POLICY

Why scf_create_risk needs a policy

This tool creates new entries in a risk register, which is a data structure that can be updated or removed later. While it populates risk metrics (likelihood and impact scores) that inform compliance and security decisions, the operation itself is write-capable and reversible—risk assessments can be edited or deleted. The tool does not execute external code, delete data irreversibly, or move money.

From the tool's definition Tool description explicitly states 'Create a new risk assessment' and 'write — editor+ role', indicating data creation with reversible modification capability.
