This takes you from approved PRODUCT.md and TECH.md specs to shipped code, all in one PR. You read the specs, implement against them, then update the specs as reality shifts during development. The idea is to keep everything in sync so reviewers see the feature that actually ships, not just the original design. It'll optionally suggest a PROJECT_LOG.md or DECISIONS.md for complex features, but mostly it's just building against specs and making sure nothing drifts. Works best when your team already lives in a specs directory structure and wants implementation changes and spec tweaks committed together instead of letting docs rot.
