What cancel_slurm_job does on CLIO Adios
AI agents call cancel_slurm_job to permanently remove resources in CLIO Adios, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why cancel_slurm_job is rated Critical
Cancelling a Slurm job is an irreversible action — a terminated job loses its execution state, queued work, and any in-progress computation cannot be resumed from where it was stopped. This is a destructive operation with potentially high blast radius if a long-running scientific compute job is terminated prematurely.

The rule that runs cancel_slurm_job safely
PolicyLayer is an MCP gateway: it sits between your AI agents and CLIO Adios, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For cancel_slurm_job, this is the rule to start with:
cancel_slurm_job is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect CLIO Adios, apply this rule, and every cancel_slurm_job call is checked against it from then on.
