gt_sling · Ruflo MCP: Risk & Policy

WHAT IT DOES

What gt_sling does on Ruflo

AI agents use gt_sling 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 gt_sling needs a policy

The tool assigns (slings) a bead (work item/task) to an agent for processing. This is a Write operation — it creates an assignment or queues a task in the system. It does not delete data (not Destructive), run arbitrary code directly (not Execute in the strictest sense), or move money (not Financial).

From the tool's definition 'Sling (assign) a bead to a Gas Town agent for processing' — assigns/queues a work item to an agent

gt_sling Rate-limited

gt_sling stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
