@eriner I use GitHub speckit primarily. Experimenting with open spec, in Claude (personal) copilot (work)
"Spec Driven Development" sounds like big upfront design, but with these frameworks it's not. It's small changes, 2 to 5 use cases.
You give the agent as little or much detail as you want. It's a multi-step generative process:
Spec (requirements, uses cases)
Research ("decisions")
Plan (phased, what code to write)
Tasks: fine grained steps
