How a feature ships here

The superpowers build loop, with a real shipped feature as evidence: brainstorm → spec → plan → TDD → review → merge-commit PR.

The workflow

Donna is built with a disciplined loop (see CLAUDE.md §6): brainstorm → spec → plan → test-driven implementation → review → PR. Designs land in docs/superpowers/specs/, plans in docs/superpowers/plans/. Scale the ceremony to the change, but anything that adds a surface or touches the API contract gets a spec.
