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).
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. :)
I think they might be in the process of re-designing the site and/or moving docs because it all used to work not that long ago, but the site design was completely different last time I checked.
This looks like exactly what I've been thinking I needed. I've tried Superpowers, GSD and oh-my-claude/openagent and mostly they burn more tokens.
Lately I've been using stock OMP and its close to the right balance but not quite enough of the brainstorming and spec maintenance built in. I've tried to layer some simple stuff on myself but with mixed results.
I've been using this, or more pointedly, I built an agent fleet (bespoke harness) where the planner agent uses OpenSpec to generate the plan. Then turns the tasks into a ticket graph.
It works fairly well, and it is definitely less heavy than SpecKit.
The CLI is actually useful. It gives the skills a way to deterministically interact with the spec. For example, it can validate the shape without having to spend tokens reading the files.
There seems to be a spectrum from fluid, iterative workflows like OpenSpec to more up-front alignment and control like Matt Pocock skills.
Curious what people have settled on.
Last week, I gave a 471 line spec to implement a major feature and it didn’t flinch. I wrote about it here.

Somehow not very confidence inspiring...

Why does it need to have an entire CLI?
