Deliver User Stories

User Stories

User stories are concise descriptions of functionality from the user's perspective. They capture who needs something, what they need, and why - without prescribing how to build it. Good user stories enable teams to break large features into estimable, deliverable increments while maintaining focus on user value.

When to Use

• After PRD approval, when breaking down features for implementation
• During sprint planning to create actionable work items
• When writing tickets for engineering teams
• When communicating requirements to stakeholders in accessible terms
• When prioritizing a backlog based on user value

When NOT to Use

• You need deeper, QA-ready Given/When/Then coverage for a single story or slice -> use deliver-acceptance-criteria
• You need the feature-wide catalog of boundary conditions and failure scenarios -> use deliver-edge-cases
• The feature itself is not yet specified -> use deliver-prd first; stories should trace back to documented requirements
• You want refinement-session outcomes (estimates, scope decisions, open questions) -> use iterate-refinement-notes

Instructions

When asked to create user stories, follow these steps:

1. Understand the Feature Context

Review the PRD or feature description. Understand the overall goal, target users, and scope boundaries. User stories should trace back to documented requirements.

1. Identify User Personas

Determine which users interact with this feature. Each story should be written for a specific persona, not generic "users." Different personas may need different stories for the same feature.

1. Break Down by User Goal

Decompose the feature into distinct user goals. Each story should deliver a complete, valuable capability - something the user can actually do when the story is done.

1. Write Story Statements

Use the format: "As a [persona], I want [action] so that [benefit]." The benefit clause is critical - it explains why this matters and helps prioritize.

1. Define Acceptance Criteria

Write specific, testable criteria using Given/When/Then format. Acceptance criteria define "done" - if all criteria pass, the story is complete.

1. Apply INVEST Criteria

Validate each story against INVEST: Independent, Negotiable, Valuable, Estimable, Small, Testable. Revise stories that don't meet these criteria.

1. Add Context and Notes

Include relevant design references, technical considerations, and dependencies. These help implementers understand the full picture.

Output Format

Use the template in references/TEMPLATE.md to structure the output. A complete output carries, per story: Story Header; User Story Statement; Context & Background; Acceptance Criteria; Design Notes; Technical Notes; Dependencies; Out of Scope; and Open Questions where any remain. Multi-story documents nest these sections under one heading per story, as the example shows.

Quality Checklist

Before finalizing, verify:

• [ ] Each story follows "As a... I want... so that..." format
• [ ] Stories are independent (can be built in any order)
• [ ] Acceptance criteria use Given/When/Then format
• [ ] Each criterion is testable (someone can verify pass/fail)
• [ ] Stories are small enough to complete in one sprint
• [ ] No implementation details in the story statement
• [ ] Benefit clause explains why this matters to the user

Examples
