Summary
One spec-driven framework grew 863% in six months. Another in the same category grew 18%. This is the honest six-month update on OpenSpec, BMAD, Spec Kit, Agent OS, and Taskmaster — plus the new players eating into all of them.
Last October I compared three SDD frameworks on this channel. Since then I’ve covered Taskmaster and Agent OS too, and the combined GitHub stars of those five jumped from 87,000 to 202,000. But the average hides the spread. OpenSpec ran away with it. Taskmaster stalled. Agent OS went quiet and narrowed its scope. BMAD rewrote itself from scratch. And Spec Kit rode GitHub’s brand to the top of the absolute star count.
I also cover what’s happening around the edges: Superpowers by Jesse Vincent, GSD by TACHES, Beads by Steve Yegge, and the native Claude Code features (plan mode, skills, ultra plan mode, CLAUDE.md) that are quietly absorbing what these frameworks used to do. Plus the community debate — Martin Fowler’s skeptical take, the waterfall critique from Marmelab, Marc Brooker’s AWS rebuttal, and the Prezi case study.
