OpenSpec: Spec-driven coding workflow integrated with 30 AI tools

Solves the problem of AI coding assistants producing unpredictable results by relying solely on conversation history. Adds a layer that agrees on requirements and design as clear specs before writing code, controlling the development direction.

Automatically generates proposals, requirements, designs, and task lists using slash commands. Generated specs are saved in standard Markdown format, allowing immediate review and editing without needing to learn complex syntax.

Unlike GitHub Spec Kit or AWS Kiro, it is not tied to specific IDEs or models. It supports over 30 AI tools and adopts a lightweight structure that can be flexibly applied to existing projects.

Provides scalable store features from personal projects to large teams. Manages features across multiple repositories as a single plan, improving collaboration efficiency by allowing product teams to reference specs owned by platform teams.
