Break down large stories into optimally-sized stories (1-3 days) using PSP measurement discipline.

Story Decomposition

Breaks large stories into 1-3 day slices by identifying architectural, functional, or technical boundaries.

Steps

  1. Load story context and historical sizing data from estimation-history.yaml
  2. Identify natural split boundaries (architectural, functional, technical, or temporal)
  3. Create story candidates with scope, value statement, and initial sizing
  4. Apply PROBE estimation; split stories >24h, combine stories <4h
  5. Sequence stories by dependencies and generate decomposition report
