Refactoring

This directory contains detailed refactoring plans for improving the codebase. Each document outlines specific improvements, implementation strategies, and progress tracking.

📋 Purpose

Refactoring plans serve to:

• Document planned improvements before implementation
• Track progress on ongoing refactoring work
• Provide context for reviewers and future maintainers
• Align team on technical improvements
• Preserve decisions and rationale

📁 Active Refactoring Plans

See active-refactorings.md for the current list of ongoing refactoring work.

✅ Completed Refactorings

See completed-refactorings.md for the complete history of finished refactoring work.

Meta-Documentation (at root):

• README.md - Explains the refactoring process and conventions
• TEMPLATE.md - Template for creating new refactoring plan documents
• active-refactorings.md - Index of current ongoing refactoring work
• completed-refactorings.md - Historical record of finished refactorings

Refactoring Plan Documents (plans/ subdirectory):

• Each active refactoring has a detailed plan document in plans/
• These contain the full implementation details, progress tracking, and technical specifications
• When refactoring is complete, the plan document is typically deleted or archived

File Management Process:

1. New refactoring: Create plan document in plans/, add entry to active-refactorings.md with status 📋 Planning
2. Start work: Update status to 🚧 In Progress in active-refactorings.md
3. Complete work: Move entry from active-refactorings.md to completed-refactorings.md
4. Cleanup: Delete the detailed plan document from plans/ (work is now in git history)

🎯 Plan Structure

Each refactoring plan follows this structure:

1. Overview: Summary of goals and scope
2. Progress Tracking: Current status and completion metrics
3. Phased Proposals: Organized by impact and effort
4. Implementation Details: Code examples and checklists
5. Timeline: Estimated duration and sprint planning
6. Review Process: Approval and completion criteria

📊 Status Legend

• 📋 Planning - Document created, awaiting review and approval
• 🚧 In Progress - Implementation has started
• ✅ Completed - All proposals implemented and merged
• ⏸️ Paused - Work temporarily suspended
• ❌ Cancelled - Plan was abandoned or superseded

🔄 Workflow

1. Creation

1. Identify area needing refactoring
2. Create detailed plan document in this directory
3. Organize proposals by impact/effort ratio
4. Add implementation checklists and timeline
5. Add entry to active-refactorings.md with status 📋 Planning

2. Review and Approval

1. Team reviews plan for technical feasibility
2. Validate alignment with project principles
3. Approve or request modifications
4. Set implementation timeline

3. Implementation

1. Update status to 🚧 In Progress in active-refactorings.md
2. Create tracking issue (optional)
3. Create feature branch
4. Implement proposals in priority order
5. Update progress in plan document
6. Run tests and linters after each change

4. Completion

1. Final verification of all changes
2. Update plan document status to ✅ Completed
3. Move refactoring entry from active-refactorings.md to completed-refactorings.md
4. Delete the refactoring plan document (or archive if needed for reference)
5. Create pull request
6. Merge after review approval

🎓 Best Practices

When to Create a Refactoring Plan

Create a plan when:

• ✅ Changes affect multiple functions or modules
• ✅ Multiple improvements should be coordinated
• ✅ Work will span multiple sessions or PRs
• ✅ Team alignment is needed before starting
• ✅ Changes require careful sequencing

Skip a formal plan for:

• ❌ Single-function improvements
• ❌ Obvious bug fixes
• ❌ Trivial style changes
• ❌ Urgent hotfixes

Plan Quality

Good refactoring plans:

• ✅ Prioritize by impact/effort - Quick wins first
• ✅ Include code examples - Show before/after
• ✅ Provide checklists - Track implementation steps
• ✅ Document rationale - Explain why, not just what
• ✅ Set realistic timelines - Based on team capacity
• ✅ Align with principles - Support project goals

Progress Tracking

Update progress regularly:

• After each proposal: Mark as completed
• Weekly: Update summary metrics
• Phase completion: Update phase status
• Issues/blockers: Document in plan

💡 Tips

For Plan Authors

• Start with high-level goals before diving into details
• Group related changes into logical phases
• Estimate conservatively - refactoring often takes longer than expected
• Get early feedback on the plan structure
• Keep it updated as implementation progresses

For Implementers

• Read the entire plan before starting work
• Follow the phase order unless there's a strong reason not to
• Update progress after completing each proposal
• Run tests frequently to catch issues early
• Ask questions if anything is unclear

For Reviewers

• Check alignment with project principles
• Validate priorities - are high-impact items first?
• Verify feasibility - can this actually be done?
• Suggest improvements - what's missing?
• Approve clearly - signal when implementation can begin
