Build

This is a meta-skill that chains other Claude skills together into complete development workflows. Instead of manually running discovery, then planning, then implementation separately, it orchestrates the handoffs for you with human checkpoints at phase boundaries. Four modes handle common scenarios: greenfield for new features, brownfield when you need to understand existing code first, TDD for test-first development, and refactor with impact analysis. The interactive question flow is well thought out, it actually walks you through workflow selection if you're not sure what you need. Honestly feels like the kind of automation you build after running the same skill sequences dozens of times and getting tired of the ceremony.
