WHAT IT DOES

What scf_trigger_dpsia does on Scf

AI agents use scf_trigger_dpsia 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_trigger_dpsia needs a policy

The tool queues/triggers an assessment process, which is a write operation that creates a new assessment job. It does not delete data or move money. The blast radius is medium because triggering an erroneous DPSIA against a vendor could produce inaccurate compliance records and affect vendor risk posture scores, but it is reversible and does not cause direct data destruction or financial harm.
