hooks_session-restore · Ruflo MCP: Risk & Policy

WHAT IT DOES

What hooks_session-restore does on Ruflo

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

WHY IT NEEDS A POLICY

Why hooks_session-restore needs a policy

Restoring a session involves writing or overwriting current session state with previously saved data. This is a Write operation (reversible in principle), but carries high severity because in a multi-agent swarm context, restoring the wrong session could cause agents to operate with stale or incorrect context, potentially triggering unintended autonomous workflows.

From the tool's definition 'Restore a previous session' — restores state from a previous session, implying write/modification of current session state
