# User Story Creation

Break Product Backlog Items into implementable user stories.

## When to Use
- PBI ready for story breakdown
- Feature needs vertical slicing
- Creating sprint-ready work items

## Quick Reference

### Workflow
1. Read PBI artifact and acceptance criteria
2. Identify vertical slices (end-to-end functionality)
3. Apply INVEST criteria to each story
4. Create user stories with GIVEN/WHEN/THEN
5. Save to `team-artifacts/pbis/stories/`
6. Suggest next: `/test-spec` or `/design-spec`

### INVEST Criteria
- **I**ndependent: No dependencies on other stories
- **N**egotiable: Details can change
- **V**aluable: Delivers user value
- **E**stimable: Can estimate effort
- **S**mall: Completable in sprint
- **T**estable: Clear acceptance criteria

### Output
- **Path:** `team-artifacts/pbis/stories/{YYMMDD}-us-{slug}.md`
- **Format:** As a {role}, I want {goal}, so that {benefit}

## Task Planning Notes

- Always plan and break many small todo tasks
- Always add a final review todo task to review the works done at the end to find any fix or enhancement needed
