Why we included this project

OpenSpec sits between you and your AI coding assistant and makes the assistant plan before it writes any code. You describe the change in plain language, the assistant comes back with a proposal, the spec deltas, a design, and a task list, and you both review that plan before implementation starts. That review is where the value shows up: a wrong turn costs a quick edit instead of a pile of generated code. It's built for brownfield codebases, so it works with small delta specs rather than asking you to document the whole system up front, and it scales from a personal project to an enterprise. If you want AI-assisted changes you can review and predict instead of one-shot generations, this gives you a lightweight process for that.
