Sparring

Sparring is a code directory tool with five AI personas that interrogate specs before agents build them.

Sparring provides five AI personas that interrogate a spec sequentially before an agent builds from it. It helps catch gaps on the page rather than in production by running distinct lenses including PM, architecture, UX, and QA. Users can run personas on-demand while drafting or through a full pipeline before the build phase. The library supports inputs from files or chat sessions and integrates with workflows like OpenSpec and Superpower. It operates in summary or detailed output modes and saves findings for human review.
