superskills_invoke · Superskills MCP: Risk & Policy

WHAT IT DOES

What superskills_invoke does on Superskills

AI agents invoke superskills_invoke to trigger actions in Superskills. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why superskills_invoke needs a policy

An 'invoke' operation on a CLI skill gateway most likely triggers execution of external commands or scripts with effects determined by arguments. This is Execute category due to potential for running arbitrary code or shell commands. High severity because such invocations could have wide-ranging side effects depending on which skills are exposed and what arguments an AI agent supplies.

From the tool's definition Tool name 'superskills_invoke' combined with server description stating it 'exposes your local CLI skills to any AI assistant' indicates invocation of local commands or scripts. Sibling tool 'superskills_run' reinforces this pattern.
