fission-ai/openspec is a spec-driven development framework for AI coding assistants. The latest release shown on the GitHub repository is v1.14.3. The provided information does not record the changes in this version. According to the README, OpenSpec helps people and AI align on requirements and implementation plans before code is written. It is written in TypeScript and offered under the MIT license.
Spec-driven development means documenting first what you are going to build and using that document as the reference for planning and implementation. OpenSpec writes specifications in Markdown with no special syntax. For each change you can organize a proposal, requirements and scenarios, a design, and a task list. You explore ideas with `/opsx:explore` and propose changes with `/opsx:propose`, and the extended workflow also includes commands for applying and archiving tasks. It is a tool for organizing agent work in an existing codebase through proposals, specifications, tasks, verification, and archival. The star count shown on GitHub is 72755.
However, the provided material does not show what changed in v1.14.3, nor does it give the result of applying this procedure. The composition of the workflow can therefore be confirmed, but whether actual use raises implementation quality is hard to judge from this information alone.
