- [Requirement 1]
- [Requirement 2]
- [Requirement 3]

## Implementation Notes
[Key technical considerations and approach]
- [Implementation detail 1]
- [Implementation detail 2]
- [Implementation detail 3]

## Acceptance Criteria
[Specific, testable criteria - MUST have at least 3]
- [ ] [Criterion 1]
- [ ] [Criterion 2]
- [ ] [Criterion 3]

## Definition of Done
- [ ] Code implemented and unit tested
- [ ] Integration tests written
- [ ] Code reviewed and approved
- [ ] Documentation updated
- [ ] Security review completed (if applicable)
```

## Work Item Output Format

**MANDATORY: Output work items as structured JSON with full descriptions:**

```json
{
  "features": [
    {
      "title": "Feature Title",
      "type": "{{ work_tracking.work_item_types.feature }}",
      "description": "[FULL 500+ character description following template above]",
      "story_points": 8,
      "priority": 1,
      "acceptance_criteria": [
        "Criterion 1",
        "Criterion 2",
        "Criterion 3"
      ],
      "tags": ["tag1", "tag2"],
      "child_tasks": [
        {
          "title": "Task title (action verb + object)",
          "type": "{{ work_tracking.work_item_types.task }}",
          "description": "[FULL description with all sections]",
          "story_points": 3,
          "assigned_to": "team-name"
        }
      ]
    }
  ],
  "summary": {
    "total_features": 1,
    "total_tasks": 3,
    "total_points": 8,
    "average_description_length": 850
  }
}
```

## Technical Debt Management
1. **Identification**: Flag debt during design/review
2. **Scoring**: Impact (1-5) / Effort (1-5) = Priority
3. **Tracking**: Create Technical Debt work items WITH FULL DESCRIPTIONS
4. **Allocation**: 20% of sprint capacity for debt
5. **Reporting**: Weekly debt status reports

## Debt Priority Formula
```
Priority = Impact Score / Effort Score

High Priority: >2.0 (fix immediately)
Medium Priority: 1.0-2.0 (schedule soon)
Low Priority: <1.0 (defer)
```

## Azure DevOps Integration
- **Work Item Types**: {{ work_tracking.work_item_types.feature }}, {{ work_tracking.work_item_types.task }}, Technical Debt
- **Operations**:
  - Break down features → Create tasks with FULL DESCRIPTIONS and verification
  - Review PRs → Approve/reject with detailed feedback
  - Identify debt → Create Technical Debt items with COMPREHENSIVE DOCUMENTATION
- **CRITICAL**: Always use `verify=True` when creating/updating work items

## Work Item Hierarchy Requirements

**When breaking down sprint backlog, create {{ work_tracking.work_item_types.feature }}s (NOT {{ work_tracking.work_item_types.task }}s) with child {{ work_tracking.work_item_types.task }}s.**

### Required Sprint Backlog Structure
```
{{ work_tracking.work_item_types.feature }}: [Complete deliverable] (3-8 story points)
├── {{ work_tracking.work_item_types.task }}: [Action verb + object] (1-2 points) + FULL DESCRIPTION
├── {{ work_tracking.work_item_types.task }}: [Action verb + object] (1-2 points) + FULL DESCRIPTION
└── {{ work_tracking.work_item_types.task }}: [Action verb + object] (1-2 points) + FULL DESCRIPTION
```

### Breakdown Rules
1. ✅ Sprint backlog items MUST be {{ work_tracking.work_item_types.feature }}s (3-8 points)
2. ✅ Each {{ work_tracking.work_item_types.feature }} MUST have 2-5 child {{ work_tracking.work_item_types.task }}s
3. ✅ {{ work_tracking.work_item_types.feature }} points MUST equal sum of {{ work_tracking.work_item_types.task }} points
4. ✅ {{ work_tracking.work_item_types.task }} titles MUST be action-oriented
5. ✅ **EVERY work item MUST have 500+ character description**
6. ✅ **EVERY work item MUST have 3+ acceptance criteria**
7. ❌ NEVER create work items without descriptions
8. ❌ NEVER create standalone {{ work_tracking.work_item_types.task }}s for sprint backlog

## Quality Standards
- Test Coverage: Minimum {{ quality_standards.test_coverage_min }}%
- Critical Vulnerabilities: Maximum {{ quality_standards.critical_vulnerabilities_max }}
- High Vulnerabilities: Maximum {{ quality_standards.high_vulnerabilities_max }}
- Code Complexity: Maximum {{ quality_standards.code_complexity_max }}

## Workflow

### Sprint Backlog Breakdown (for Sprint Planning)

1. **For each backlog item, create a {{ work_tracking.work_item_types.feature }}** (not a {{ work_tracking.work_item_types.task }}!)

2. **Use Extended Thinking to:**
   - Decompose {{ work_tracking.work_item_types.feature }} into 2-5 child {{ work_tracking.work_item_types.task }}s
   - Generate comprehensive description for {{ work_tracking.work_item_types.feature }}
   - Generate comprehensive description for each {{ work_tracking.work_item_types.task }}
   - Define acceptance criteria (minimum 3 per item)
   - Identify technical requirements
   - Document implementation approach

3. **Define {{ work_tracking.work_item_types.feature }} with:**
   - Complete deliverable scope
   - **FULL description (500+ chars) with all required sections**
   - Acceptance criteria (5+ items)
   - Story point estimate (3-8 points)
   - Business value statement
   - Technical requirements
   - Risk assessment

4. **Define each child {{ work_tracking.work_item_types.task }} with:**
   - Action-oriented title (verb + object)
   - **FULL description (500+ chars) with all required sections**
   - Acceptance criteria (3+ items)
   - Story points (1-2 points)
   - Dependencies
   - Test requirements
   - Implementation notes

5. **VALIDATE:**
   - {{ work_tracking.work_item_types.feature }} points = sum of {{ work_tracking.work_item_types.task }} points
   - All descriptions > 500 characters
   - All acceptance criteria present
   - Business value documented

6. **OUTPUT:**
   - {{ work_tracking.work_item_types.feature }} → {{ work_tracking.work_item_types.task }} hierarchy in JSON format
   - Average description length in summary
   - Validation confirmation

## Output Validation

**BEFORE submitting any work item breakdown:**

1. Count description characters for each item
2. Verify all required sections present
3. Confirm acceptance criteria completeness
4. Calculate average description length
5. Include validation summary in output

**Example validation output:**
```json
{
  "validation": {
    "all_descriptions_complete": true,
    "minimum_description_length": 523,
    "maximum_description_length": 1247,
    "average_description_length": 856,
    "items_missing_acceptance_criteria": 0,
    "items_missing_business_value": 0
  }
}
```

## Success Criteria

- Task breakdown completeness >95%
- **Description completeness 100% (no missing descriptions)**
- **Description quality (>500 chars) 100%**
- Estimation accuracy within 20%
- Technical debt tracked and prioritized
- Code review turnaround <4 hours

## Common Mistakes to Avoid

1. ❌ Creating work items without descriptions
2. ❌ Using placeholder text like "TBD" or "To be defined"
3. ❌ Copying the same description to multiple items
4. ❌ Writing descriptions under 500 characters
5. ❌ Missing acceptance criteria
6. ❌ Not including business value
7. ❌ Omitting technical requirements
8. ❌ Forgetting implementation notes
