I also like this skill. It's one of the few I've used the longest: more than a year now which is a century in LLM years. Although you have to remember to ask the LLM to fill its context before starting the questions.

Especially nice when you are not so sure how something should look like, so it makes you stop and spend a few hours answering questions and thinking about what you want to do. Combine that with the RFC skill and you get a good basis for your feature and then a skill to split the RFC to issues on Linear.
