SLDD (Spec Loops Driven Development) is a specs-driven feedback loop for AI-assisted development. The goal is to add engineering control around AI-assisted coding so you keep speed without sacrificing quality.

Run one skill at a time. Review and approve the output before moving to the next step.

No implementation prompts (steps 04-05) before intent and design (steps 01-03) are reviewed and approved. If a gap appears at any step, loop back to the earlier step and revise.

For existing codebases, use sldd-99-existing-codebase-understanding-and-context-summary after step 01 and before step 02 to ground all design decisions in the current architecture and conventions. Skip for greenfield projects.
