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.

Story Log

File: docs/stories/<YYYYMMDDTHHMMSS>_<name>.story.md

date -u +"%Y%m%dT%H%M%S"  # Generate timestamp

Use the story-template skill for structure.

Epic Documents

Directory: docs/stories/<YYYYMMDD>_<epic-name>/ File: <YYYYMMDDTHHMMSS>_<epic-name>.epic.md

Use the epic-template skill for structure.
