User Story Generator

User Story Format

Standard Format

As a [role/persona],
I want [goal/feature],
so that [benefit/value].

Extended Format (with context)

As a [role/persona],
In the context of [situation/scenario],
I want [goal/feature],

Edge Case Stories

Common Edge Cases

## Edge Case Stories for [Feature]

### Empty State
As a new user,
When I have no [items/data/history],
I want to see a helpful empty state with a clear CTA,
so that I know how to get started.

### Error Recovery
As a user,
When an operation fails (network error, timeout, server error),
I want to see a clear error message with a retry option,
so that I can recover without losing my work.

### Boundary Values
As a user,
When I enter the maximum allowed value (e.g., 10,000 characters in a text field),
I want to see a character counter and graceful truncation,
so that I know my limits before submitting.

### Concurrent Access
As a user,
When another user edits the same resource simultaneously,
I want to be notified of the conflict,
so that I don't accidentally overwrite their changes.

### Offline / Slow Connection
As a mobile user,
When I lose network connectivity,
I want my pending actions to be queued and synced when back online,
so that I don't lose my work.

### Permission Denied
As a user without admin privileges,
When I try to access an admin-only feature,
I want to see a clear message explaining why access is denied,
so that I can request access if needed.

### Data Migration
As an existing user,
When the system migrates to a new version,
I want my existing data to be preserved and correctly mapped,
so that I don't lose any information.

Edge Case Discovery Checklist

• What if the input is empty?
• What if the input is at maximum length?
• What if the input contains special characters / unicode?
• What if the user double-clicks / double-submits?
• What if the network fails mid-operation?
• What if the user has no permission?
• What if the data doesn't exist (404)?
• What if there are concurrent modifications?
• What if the browser is resized / mobile view?
• What if the user navigates away mid-process?
• What if the session expires during an action?
• What if the third-party service is down?

Non-Functional Requirement Stories

Performance

As a user,
I want the dashboard to load within 2 seconds,
so that I can quickly access my data without frustration.

Acceptance Criteria:
- Given normal network conditions (4G+)
- When the user navigates to the dashboard
- Then the page is fully interactive within 2 seconds
- And the Largest Contentful Paint (LCP) is < 2.5s
- And the First Input Delay (FID) is < 100ms

Security

As a security-conscious user,
I want my session to expire after 30 minutes of inactivity,
so that my account is protected if I forget to log out.

Acceptance Criteria:
- Given the user has been inactive for 30 minutes
- When the user tries to perform an action
- Then the user is redirected to the login page
- And a "Session expired" message is shown
- And no sensitive data remains in the browser

Accessibility

As a user with visual impairment,
I want all form fields to have proper labels and error announcements,
so that I can use the application with a screen reader.

Acceptance Criteria:
- Given all form fields have associated labels (aria-label or <label>)
- When a validation error occurs
- Then the error is announced by the screen reader (aria-live)
- And focus moves to the first invalid field
- And color is not the only indicator of error state

Scalability

As a system,
I need to handle 10,000 concurrent users without degradation,
so that the service remains reliable during peak usage.

Acceptance Criteria:
- Given 10,000 concurrent users
- When performing standard operations
- Then response time remains < 500ms (p95)
- And error rate stays < 0.1%
- And CPU usage stays < 80%

Reliability

As a user,
I want my data changes to be saved even if the server crashes,
so that I never lose my work.

Acceptance Criteria:
- Given the user submits a form
- When the server acknowledges the request
- Then the data is persisted to durable storage
- And a power failure does not result in data loss
- And transactions are ACID-compliant

Story Quality Checklist

Before Sprint Planning

• Story follows "As a... I want... so that..." format
• INVEST criteria all met
• Acceptance criteria written in Given-When-Then
• Happy path + at least 2 error scenarios covered
• Size is estimable (team agrees on story points)
• No technical jargon (understandable by non-devs)
• Dependencies identified and resolved
• Design/wireframe attached if UI story
• Edge cases identified
• NFR implications noted

Common Story Smells

Smell	Symptom	Fix
Too vague	"As a user, I want a better experience"	Be specific about what "better" means
Too technical	"As a developer, I want to refactor the DB"	Reframe as user value
Too large	Team can't estimate confidently	Decompose into smaller stories
No value	"Create config file"	Attach to a user-facing story
Hidden dependency	"Requires API not built yet"	Make dependency explicit, plan accordingly
Gold plating	15 acceptance criteria	Split into multiple stories
