prd-to-plan

Vertical-slice planning is an approach that creates narrow, complete implementation phases delivering end-to-end value. It spans architecture, data, APIs, and UI considerations, ensuring each phase is independently functional rather than just a horizontal layer.

Tracer-bullet planning in project management divides a PRD into narrow, end-to-end vertical slices that traverse all layers from architecture to tests. This method generates durable phases that deliver complete value and capture architectural decisions across the roadmap.

Yes, you can generate a phased roadmap directly from a PRD. The tool reads the product requirements and outputs a Markdown plan file using a durable template, organizing the work into tracer-bullet vertical slices ready for implementation milestones.

Yes, the generated plan includes architectural decisions and API data models. It structures the PRD into vertical slices that explicitly span architecture, data models, APIs, UI, and tests to ensure comprehensive end-to-end coverage.

The implementation plan uses a Markdown format. It writes the structured plan to a file under the ./plans/ directory, following a consistent and durable plan template for easy reading and version control.
