That's fair, gsd, superposers and spec kit are way more mature and complete. On the other hand, this skill is indeed narrower, and as a result currently intended for spec generation only, standard markdown output and allowing work alongside any of those frameworks at the spec later. Different scopes instead of a replacement.

Thanks for your input and the provided references as well as taking your time for reading this show HN.

Sure, this skill is narrower and that might be its advantage, if you don't try to make it solve everything but instead if you evolve it to solve some particular use cases.
