This is my first time seeing openspec, and it seems to share a similar philosophy to what I've been working on this year.
If you like this / SDD, I'd appreciate your feedback:

Similar iterative specs philosophy. Ours is a bit different because we focus on declarative specs and installable agent skills. We chose Go for simplicity and minimal requirements (single binary).
Please don't take this as offense, I'm honestly curious as I'm pretty bad at these things.
You say this is your first time seeing openspec, but you've been working on a pretty similar project for a year now. Openspec and Speckit both seem to have similar (almost same?) goal as yours. Do you just jump into such a project as yours without worrying about others already existing?
I tend to overthink such stuff...
I did a similar thing. Yours seems cleaner than mine. I have a 'compiler' and a sexp based DSL. I don't know how anybody vibecodes medium or large programs, say above 50,000 lines of code. I don't read all the spec until I sense something is out of alignment.
Ive wondered if I have too much complexity, and from time to time I do a "prompt astrology reset" where I get rid of all the extra cruft. I can't go without the spec sheets though.
Thanks for having a look!
On removing cruft: one of the key features of spekk is an "observer" agent role that is tasked with finding drift. On a production codebase, I run this daily in a sandbox. It pulls the latest changes and looks for specs that are mismatched from the implementation, preferring to look at specs and code that changed recently and prioritizing "major" drift events. The observer agent then opens a PR wkth its observations (markdown with YAML like the specs). It also posts a summary to Slack, but that's optional. The sandbox agent code is part of the spekk-cli codebase.
I've also been building something like this, and browsing spekk-cli, it's interesting to see that we ended up with similar roles. Might be fun to compare and contrast a couple of these systems. :)
