Why we included this project

OpenSPDD is a cross-platform command-line tool that turns AI coding prompts into structured design contracts instead of one-off instructions. It installs as a single binary, detects the coding environment, and drops SPDD command templates into assistants like Cursor, Claude Code, GitHub Copilot, and Codex. The REASONS Canvas framework asks the model to fill in seven explicit dimensions, from requirements and entities to operations, norms, and safeguards, so the AI works from precise method signatures and error handling rather than a vague task list. A reverse-sync command pushes code changes back into the design document, which keeps the design honest as the code evolves. Teams that are tired of AI assistants drifting from the intended architecture will find this a practical way to constrain and audit the generation process.
