To create a combined PRD and TDD plan, you research requirements, clarify ambiguities, and generate a unified document containing problem statements, design rationale, and implementation plans saved to artefacts/plan-with-tdd-and-prd.md.

A PRD+TDD planning artefact is a unified document that standardizes feature launches by capturing problem statements, functional requirements, technical specifications, and implementation plans to reduce ad-hoc planning errors.

The best way to structure feature planning documentation is using a combined PRD+TDD artefact that guides clarifications, captures dependencies, and outlines open questions alongside functional and technical requirements.

Yes, this planning workflow works for both product and engineering contexts, satisfying functional requirements for documenting problem statements, solution overviews, and technical specifications across both domains.

You document open questions and dependencies by generating a structured planning artefact that forces clarification of ambiguities and captures research notes alongside functional and technical requirements.

Ad-hoc feature planning causes errors because it lacks structured documentation, which you standardize by forcing a combined PRD+TDD artefact that captures design rationale and implementation plans for traceability.
