Produce one human-reviewed seed containing a clear parent problem and ordered candidate stories. Do not perform technical design or write an executable plan.
Use this skill when the beneficiary, problem, desired effect, or value is unclear; a request prescribes a solution without establishing why; several outcomes or story boundaries must be chosen; or the first increment's value or learning priority is disputed.
For selected-story goal, scope, and examples, use dough-story-refinement. Hand off one understood story to the project's execution-planning workflow only when the user explicitly requests planning. A seed or backlog selection does not authorize execution.
Read the user's instructions and repository guidance to identify:
Resolve project paths from this project, not this skill's location. If context or a linked dependency needed for the current action is unavailable, name it, ask only for the missing information, and stop the affected activity before writing.
Read and follow problem decomposition to establish human-owned framing decisions, challenge alternatives, and select, size, and order stories. Before writing to the seed, establish or reuse the required workspace under preparation workspace; this discussion and decomposition work needs no workspace on its own. Then use seed format to update the supplied seed or create a new seed in that workspace. After a write that leaves a candidate with a recorded identity in its canonical home, apply record preparation facts. Leave the seed there for review by default; this skill commits or publishes it only through that reference's disposition.
Report the seed path, recommended first story, rejected simpler alternative, effort distribution, and open decisions. Apply that reference's keep or discard decision, then close or retain the workspace, when this session ends. After writing the seed, end with:
