# Enhancement Workflow

## Overview

The enhancement workflow is designed for **minor enhancements** to existing functionality. It uses a streamlined, single-document approach where the spec, plan, and tasks are condensed into one file for quick implementation.

## When to Use

Use `/speckit.enhance` when:

- Adding small improvements to existing features
- Making minor UI/UX enhancements
- Adding simple helper functions or utilities
- Improving error messages or user feedback
- Adding minor configuration options
- Making small performance optimizations
- Adding simple validation or edge case handling

**Do NOT use `/speckit.enhance` for**:
- Major new features → use `/speckit.specify` instead
- Bug fixes → use `/speckit.bugfix` instead
- Changing existing feature behavior → use `/speckit.modify` instead
- Large refactoring efforts → use `/speckit.refactor` instead
- Emergency fixes → use `/speckit.hotfix` instead

**Rule of thumb**: If it needs more than 1 phase or complex planning, use `/speckit.specify` instead.

## Process

### 1. Planning Phase
- Document the enhancement in a single file
- Define what's changing and why
- Create a simple, single-phase plan with tasks
- Identify files to modify

### 2. Implementation
- Follow the task list
- Write tests as needed
- Make the changes
- Verify everything works

### 3. Verification
- All tests pass
- No regressions
- Documentation updated if needed

## Quality Gates

- ✅ Enhancement MUST be small enough for a single-phase plan
- ✅ Changes MUST be clearly defined
- ✅ Tests MUST be added for new behavior
- ✅ All tests MUST pass before marking complete

## Files Created

```
specs/
└── enhance/
    └── 001-description/
        └── enhancement.md      # Single document with spec + plan + tasks
```

## Command Usage

```bash
/speckit.enhance "add tooltip to save button"
```

This will:
1. Create branch `enhance/001-add-tooltip-to`
2. Generate `enhancement.md` with condensed template
3. Set `SPECIFY_ENHANCE` environment variable
4. Ready for immediate implementation

**Next steps after running the command:**
1. Review and complete the enhancement document
2. Follow the implementation tasks
3. Verify all tests pass
4. Mark as complete

## Example Enhancement

```markdown
# Enhancement: Add Tooltip to Save Button

**Enhancement ID**: enhance-001
**Priority**: Low
**Component**: UI Components

## Overview
Add a helpful tooltip to the save button explaining what data will be saved.

## Proposed Changes
- Add tooltip component to SaveButton
- Include text: "Save profile changes to database"

**Files to Modify**:
- components/SaveButton.tsx - add Tooltip wrapper

## Implementation Plan

**Phase 1: Implementation**

**Tasks**:
1. [ ] Import Tooltip component from UI library
2. [ ] Wrap SaveButton with Tooltip
3. [ ] Add tooltip text prop
4. [ ] Test tooltip appears on hover
5. [ ] Verify button still functions correctly

**Acceptance Criteria**:
- [ ] Tooltip appears on hover
- [ ] Tooltip text is clear and helpful
- [ ] Save functionality unchanged
```

## Comparison with Full Feature Workflow

| Aspect | Enhancement | Feature |
|--------|-------------|---------|
| **Scope** | Minor improvements | New functionality |
| **Documentation** | Single condensed file | Separate spec, plan, tasks files |
| **Planning** | 1 phase maximum | Multiple phases as needed |
| **Complexity** | Simple, quick changes | Complex, multi-step implementation |
| **Timeline** | Hours to 1 day | Days to weeks |

## Tips

### When to Upgrade to Feature

If during planning you find:
- More than 5-7 tasks needed
- Multiple phases required
- Complex architecture decisions
- Significant breaking changes
- Multiple components affected

Consider using `/speckit.specify` instead for proper feature development.

### Writing Good Enhancement Specs

```markdown
# Good: Clear and concise
Add validation to email input field to check format before submission

# Bad: Too vague
Make email better

# Good: Specific scope
Add loading spinner to login button during authentication

# Bad: Too broad (should be feature)
Redesign entire authentication flow with OAuth and SSO
```

### Common Pitfalls

- ❌ Using enhance for major features → Creates technical debt
- ❌ Skipping tests for "small" changes → Introduces bugs
- ❌ Not documenting the change → Team confusion
- ❌ Breaking existing behavior → Should use `/speckit.modify`

## Integration with Constitution

This workflow upholds:

- **Section III: Test-Driven Development** - Tests written for new behavior
- **Section VI: Workflow Selection** - Proper workflow for minor enhancements
- **Quality Gates** - Clear definition and verification required

## Related Workflows

- **Feature** - For major new functionality (multi-phase planning)
- **Modify** - For changing existing feature behavior
- **Bugfix** - For fixing defects
- **Refactor** - For code quality improvements without behavior change

## Metrics

Track these for continuous improvement:

- Average time from enhancement request to completion
- Percentage of enhancements that should have been features
- Test coverage of enhancements
- Number of enhancements per component
