Fission-AI/OpenSpec now has 69,065 GitHub stars.
- A spec-driven development (SDD) framework built for AI coding assistants like Claude Code and Cursor
- Core idea: write clear product/technical specs first, then let AI implement against them — fixing requirement drift and context loss in AI coding
- Covers context engineering, PRD management, and SDLC workflows
It's the leading open-source implementation of the "make AI code against engineering specs" methodology.
