Openspec Implementation

This walks you through implementing approved spec proposals with a structured read, execute, test, validate cycle for each task. It enforces TodoWrite tracking so you never lose sight of what's done versus what's pending, and it's strict about testing before marking anything complete. The workflow is methodical: load the proposal, set up task tracking, work through tasks sequentially, verify each one, then mark the whole thing done. Useful when you want systematic implementation with guardrails against skipping steps or batching work before validation. The discipline it enforces around incremental testing and progress tracking is the real value, especially for larger changes where it's easy to lose thread.
