The higher-level pkg for tool is not yet committed as it still needs some work. Sorry about that. Right now the raw interface is available only, and the documentation are the examples in the kubernetes tutorial. The infrastructure for supporting these packages is done, though, and the APIs are mostly written. It is mostly a matter of picking the right place in the directory structure: the pkg directory contains the core library, but the tools libraries will only be available to the scripting layer. So ideally there is a nice directory outside the pkg dir to house them.

Ah, makes sense. I was trying out some of the examples in the inline help and ran into issues with the missing packages. I was in particular interested in outputting to files which I presume is in there? eg.

task write: file.Append({

The solution is simple, actually. It is fine (and possibly useful) to gives access the tool definitions within the normal package directory --- it is just data ---, as long as the corresponding functionality is not accessible from the non-tool cue files. So it can share the pkg directory without issue.

I'll work on getting this in asap.
