    Type Alias Level

    Level: "ok" | "warn" | "error"

    A check's outcome.

    info is advisory, not diagnostic — ok is not "this check passed", it is "nothing here needs the agent's attention". A warn degrades what the agent can do (stale skills, no MCP); only error means the engine cannot be trusted to do the work.
