Epic and Story Planning

Provides structured planning workflows for epics and stories with GitHub issue integration and gherkin-based acceptance criteria.

Planning Hierarchy

CopyEpic (strategic milestone)
├── Story 1 (user-facing feature)
│   ├── Gherkin scenarios
│   └── Tasks (implementation units)
├── Story 2
└── Story 3

Epic Planning Workflow

1. Define Epic Scope

   • Clear business objective
   • Success criteria
   • Estimated complexity (DEEP: Days, not hours)

2. Break Down into Stories

   • Each story is independently deliverable
   • User-facing value per story
   • Linked to parent epic

3. Create GitHub Issues

   • Use epic.yml template for epics
   • Use story.yml template for stories
   • Apply appropriate labels

Story Detailing Workflow

1. User Story Format

   CopyAs a [user type]
   I want [feature]
   So that [benefit]
   

2. Gherkin Acceptance Criteria

   CopyFeature: [Story title]
   
   Scenario: [Happy path]
     Given [context]
     When [action]
     Then [outcome]
   
   Scenario: [Edge case]
     Given [different context]
     When [action]
     Then [different outcome]
   

3. Task Breakdown

   • 15-30 minute implementation units
   • Clear done-when criteria
   • Dependencies identified

GitHub Integration

Issue Templates

Templates available in templates/:

• epic.yml - Epic creation with goals and criteria
• story.yml - Story creation with gherkin

Label Strategy

Creating Issues

Epic:

Copygh issue create --template epic.yml --label "type-epic,status-planning"

Story:

Copygh issue create --template story.yml --label "type-story,status-planning" --milestone "Epic Name"
