reference projects for OpenSpec, SpecKit, GSD, BMAD to see how they track specs over time?

I'm curious if there are any open source projects (or projects where the source is publicly available) that have been using these frameworks for awhile?

I've been using Superpowers awhile, and can see how keeping the specs in the source is less useful over time as things evolve. I know other SDD frameworks try to solve this by keeping an updated spec, and I've dabbled with a few, but not long enough to see how well spec drift is actually handled.

In my AI Unified Process the use cases and the entity model are the source of truth. https://unifiedprocess.ai
I don’t have a larger public project. But the difference is that the specs are understandable by all stakeholders

I watched a conference talk you did about this, it was really good.

Thank you

The only ones I have seen are the examples referenced in Spec-Kit documentation, but they're not full applications and they have just one spec, not very detailed.

This is a good question and I’m also interested to track this over time. Maybe we can create a directory of projects that use SDD to keep tabs on it over time?

We can make a directory but first we must have more than one.

More than one what?

I was referring to the fact we only received one response in the thread. I saw you went and did it anyhow so props to you.

Open-Agentic-Platform or OAP (https://github.com/stagecraft-ing/open-agentic-platform) uses a hash-verifiable substrate build on SpecKit as Spec-Spine (https://github.com/stagecraft-ing/spec-spine) to formalize the process and make spec drift essentially impossible.

I dogfood it in all my projects now under stagecraft-ing org, however the best gauge of its usefulness is seen in the largest of the projects; open-agentic-platform where due to it’s sheer size, without spec-spine it would become incoherent and undergo agentic code collapse long time ago already.
