## Why arvan_task_cancel is rated Critical

Cancelling a running or scheduled task is an irreversible action — once cancelled, the task's progress and queued work are lost and cannot be recovered. This could interrupt critical infrastructure operations (provisioning, Kubernetes deployments, IaC runs, etc.) with potentially unrecoverable consequences, placing it in the Destructive category with high severity.

From the tool's own definition: "Cancel a scheduled/running background task"

## Use case

AI agents call arvan_task_cancel to permanently remove resources in ArvanCloud MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)
