What problem does it solve?
Phase 2 planning in the SDD pipeline often stalls after a spec is approved. This skill automates turning an approved Spec into a structured, review-ready Plan that captures architecture, data model, API surface, UX surface, and risk analysis, while maintaining traceability to acceptance criteria.
Core Features & Use Cases
- Convert an approved Spec into a coherent Plan (plan.md) with architecture decisions, data models, API contracts, and UX considerations.
- Auto-populate five risk categories (Security, Performance, Migration / data, Backwards compatibility, Regulatory / compliance) and provide a complete AC coverage map.
- Attach MADR-style notes for decisions and alternatives, with inline Traceability to AC IDs and a single atomic draft write to .agent-session/<spec_id>/plan.md.
Quick Start
Invoke /designer FEAT-NNN to generate a draft Plan from the current approved Spec, or use /designer FEAT-NNN --rewrite to start over.
