| description | Guides creation of user stories and epic design documents. Use when defining new features, writing Given-When-Then criteria, creating story logs, or designing larger features that need scope definition. |
Defining Stories
Epic vs Story
| Document | Purpose | When to Create |
|---|---|---|
| Epic | Design document defining scope and technical approach | Starting a larger feature |
| Story | Incremental deliverable with acceptance criteria | As needed during development |
Agile approach: Stories emerge during development. Create each story when ready to implement.
User Story Format
As a [role], I want [capability], so that [benefit].
Acceptance Criteria
- [ ] **Given** [precondition], **When** you [action], **Then** [expected result]
- Focus on user-observable behavior
- Include happy paths AND error cases
- Leave checkboxes unchecked (PO checks them)
Verification Approach
Define how criteria will be verified:
| Project Type | Options |
|---|---|
| CLI | Direct command execution |
| API | curl/httpie, API testing tools |
| Web UI | E2E tests, browser MCP tools |
| Mobile | Device/emulator, MCP tools |
| Library | Unit/integration tests |
If MCP tools or skills for testing are available, use them. If unsure, ask PO.
