prd-to-plan

Vertical-slice planning breaks a PRD into thin phases where each phase delivers a complete end-to-end path cutting through schema, API, UI, and tests. This tracer bullet approach ensures every phase produces a functional, verifiable slice of the product.

Tracer bullets in feature breakdowns build thin, end-to-end functional paths through the entire tech stack early on. This skill structures your PRD phases to trace through schema, API, UI, and tests, validating architecture before full implementation.

Yes, you can refine phase granularity before plan generation. The skill quizzes you with a proposed numbered breakdown and iterates until the phases match your intent, subsequently emitting phase drafts based on explicit acceptance criteria.

Yes, the PRD planning approach captures durable architectural decisions. It extracts stable decisions including routes, schema shapes, key data models, auth boundaries, and third-party boundaries to ensure every phase remains architecturally consistent.

The best way to structure end-to-end milestones from a PRD is using vertical slices. This skill organizes milestones so each phase cuts completely through the schema, API, UI, and tests, yielding an actionable local Markdown plan.
