AI coding plans are easy to write. Keeping them aligned with the code is the hard part.
OpenSPDD is a structured prompt-driven development methodology and cross-platform CLI for turning AI coding prompts into executable design contracts.
It helps you move from loose task lists to repeatable implementation workflows by using the REASONS Canvas to define scope, architecture, operations, coding norms, and safeguards before generation.
Key features:
• REASONS Canvas – structures Requirements, Entities, Approach, Structure, Operations, Norms, and Safeguards in one contract • Cross-tool support – generates commands for Cursor, Claude Code, GitHub Copilot, Antigravity, OpenCode, and Codex • Bidirectional sync – /spdd-sync brings code changes back into the design document • Practical command flow – /spdd-analysis, /spdd-reasons-canvas, /spdd-generate, and /spdd-sync guide the workflow • Simple distribution – install via Homebrew, go install, GitHub Releases, or the repo’s installer script
It’s open-source (MIT license).
