terryyin Resplit story
Replace one large story with smaller stories and partition its refined slice plan to match. A recommendation from slice-plan refinement alone does not authorize this workflow. Do not implement product code.
Resolve context
Require the original story and seed, its refined slice plan, and this project's seed, anchor, plan-location, and lifecycle conventions. Identify completed work, evidence, current decisions, and any existing backlog entry. Resolve backlog context when the original is queued or queueing is requested. If required context or a linked skill is unavailable, name what is missing and stop the affected activity before writing.
Establish smaller stories
Use dough-story-decomposition to decompose the original outcome and order the smaller stories. Supply the original story's established decisions and learning from refinement; reuse answered questions. Keep decomposition's seed non-executable and perform the plan mapping below only after story boundaries and order are resolved.
Split by useful outcomes, not by distributing slices into equal-sized groups. Account for the original scope across the new stories; surface proposed scope removal or changed outcomes for human resolution. Preserve unrelated siblings and stable links. Retain a trace from the original story to its replacements using this project's lifecycle conventions, so it is not left as competing work or recorded as delivered merely because it was split.
Map and realign plans
Map every original slice and its promises to the story it serves. Preserve completed work, compatible evidence, overrun history, and still-relevant decisions. Split or realign slices spanning story boundaries; do not duplicate implementation work or proof ownership. Record genuine dependencies explicitly.
Partition the original plan into one plan per new story using this project's locations. Reuse the original plan for the first story where the lifecycle allows; otherwise retain a replacement trace and retire the competing plan. Link every plan to its canonical story and account for every original slice.
For the first story in the resolved order:
- Use dough-story-refinement to establish its Goal, Scope, and Key examples, reusing compatible prior refinement.
- Realign its plan to that understanding and apply dough-slice-plan-refinement. Resolve scope, proof ownership, sizing, and dependencies on deferred work before reporting it as a refined plan. It must deliver its own outcome if later stories are deferred.
- Leave the story and plan as refined as if refined individually. If unresolved decisions prevent that result, report the resplit as incomplete rather than giving the first plan inherited readiness.
For every later story, retain the mapped slices as provisional planning input.
Mark its plan explicitly: awaiting story refinement — not ready for slice-plan refinement or execution, using equivalent project status fields where supplied.
Record that resumption requires dough-story-refinement to clarify the mapped
story's goal, scope, and examples, followed by plan realignment before slice-plan
refinement or execution. Old slice readiness does not override this hold.
Reconsider backlog placement
If the original story is queued, use dough-product-backlog to replace its entry and reassess the selected smaller stories against the whole backlog. The highest-priority replacement may retain the original position when justified. Other replacements do not inherit that position or automatically follow it; apply the backlog skill's ranking rules individually. Leave unselected candidates in their seed and explain placement or deferral. If the original was not queued, do not queue replacements unless requested.
Report
Report the replacement story links, original-to-new slice mapping, first plan's refinement and readiness result, later plans' holds and resumption steps, backlog placement rationale, and unresolved decisions. Resplitting does not authorize execution, commit, or push. End a completed resplit with:
