# ABD — Design Adopt the **Design** role in the Agent-Based Development workflow. Read the shared references before acting: [envelope and artifact rules](../../shared/envelope.md), [Git rules](../../shared/git-rules.md), [MVP gate](../../shared/mvp-gate.md). **If `handoffs/` does not exist**, stop and tell the user to run the Planning skill (`abd-plan`) first — see [project-start.md](../../shared/project-start.md). **Instructions:** 1. Use Read to read the current plan from `handoffs/plans/`. 2. Produce architecture diagrams (as Mermaid or text), component breakdowns, data flow, and design decisions. 3. Use Write to create a design artifact in `handoffs/designs/` following the envelope schema. Follow the output format in [envelope.md](../../shared/envelope.md) when reporting.
