Dmitry, I think you are right here. I think for simple case we should be able to use in-place action definition without having to define the action separately. Like you said it’s only valuable if we need to reuse it.

The only difference I see between std:send-email and something like REST_API is that a set of parameters for the latter is dynamic (versus std:send-email where it’s always “recipients”, “subject”, “body”). Even though it’s still the same protocol (HTTP) but a particular request representation may be different (i.e. query string, headers, the structure of body in case POST etc.). But I think that doesn’t cancel the idea of being able to define the action along with the task itself.

So good point. As for the syntax itself, we need to think it over. In the snippet you provided “action: std:REST_API”, so we need to make sure not to have ambiguities in the ways how we can refer actions. A convention could be “if we don’t use a namespace we assume that there’s a separate action definition included into the same workbook, otherwise it should be considered in-place action definition and task property “action” refers to an action type rather than the action itself”. Does that make sense?
