refactoring-workflow（重构工作流程）

Refactoring Workflow Skill

Systematic refactoring with tracking, validation, and completeness verification.

Quick Start

# 1. Record what you're refactoring
record_refactoring "Payment" "Transaction" "class_rename"

# 2. Update files, track progress
update_refactoring_progress "Payment" "app/models/transaction.rb"

# 3. Validate no old references remain
validate_refactoring "Payment" "Transaction"

1. Refactoring Log Functions

record_refactoring()

Start refactoring by recording what's being changed:

record_refactoring() {
  local old_name=$1
  local new_name=$2
  local refactor_type=$3  # class_rename, attribute_rename, method_rename, table_rename

  if [ -n "$TASK_ID" ] && command -v bd &> /dev/null; then
    bd comment $TASK_ID "🔄 Refactoring Log: $old_name → $new_name

**Type**: $refactor_type
**Started**: $(date -u +"%Y-%m-%d %H:%M:%S UTC")
**Status**: ⏳ In Progress

### Changes Planned

1. **$(echo $refactor_type | sed 's/_/ /g')**: \`$old_name\` → \`$new_name\`

### Affected Files (Auto-detected)

\`\`\`bash
# Ruby files referencing old name
$(rg --files-with-matches \"\\b$old_name\\b\" --type ruby 2>/dev/null | head -20 || echo "None detected")
\`\`\`

### Validation Checklist

- [ ] No references to \`$old_name\` in Ruby files
- [ ] No references in view templates
- [ ] No references in routes
- [ ] No references in specs
- [ ] No references in factories
- [ ] Migration files checked (if applicable)"
  fi
}

# Examples:
# record_refactoring "Payment" "Transaction" "class_rename"
# record_refactoring "user_id" "account_id" "attribute_rename"
# record_refactoring "payments" "transactions" "table_rename"

update_refactoring_progress()

Track progress as files are updated:

update_refactoring_progress() {
  local old_name=$1
  local file_updated=$2

  if [ -n "$TASK_ID" ] && command -v bd &> /dev/null; then
    bd comment $TASK_ID "✅ Refactoring Progress: Updated \`$file_updated\`

Old references to \`$old_name\` in this file have been updated.

Remaining files: $(rg --files-with-matches \"\\b$old_name\\b\" --type ruby 2>/dev/null | wc -l || echo "?")"
  fi
}

validate_refactoring()

Validate all references have been updated:

validate_refactoring() {
  local old_name=$1
  local new_name=$2

  echo "🔍 Validating refactoring: $old_name → $new_name"

  # Check for remaining references
  local remaining=$(rg --count "\\b$old_name\\b" --type ruby --type erb 2>/dev/null | wc -l)

  if [ "$remaining" -gt 0 ]; then
    echo "❌ Refactoring validation failed"
    echo "Found $remaining files still referencing '$old_name':"
    rg --files-with-matches "\\b$old_name\\b" --type ruby --type erb 2>/dev/null

    if [ -n "$TASK_ID" ] && command -v bd &> /dev/null; then
      bd update $TASK_ID --status blocked
    fi

    return 1
  else
    echo "✅ Refactoring validation passed"
    echo "All references to '$old_name' successfully updated."
    return 0
  fi
}

2. Complete Refactoring Workflow

Workflow Steps

1. Start: Record refactoring with record_refactoring()
2. Update: Update files incrementally, track with update_refactoring_progress()
3. Validate: Before phase completion, run validate_refactoring()
4. Fix: If validation fails, update remaining references
5. Re-validate: Run validation again until it passes
6. Complete: Only close task after validation passes

Example: Class Rename Workflow

# Phase starts: Renaming Payment to Transaction

# Step 1: Record refactoring
record_refactoring "Payment" "Transaction" "class_rename"

# Step 2: Update model file
mv app/models/payment.rb app/models/transaction.rb
# Update class name in file
sed -i 's/class Payment/class Transaction/g' app/models/transaction.rb
update_refactoring_progress "Payment" "app/models/transaction.rb"

# Step 3: Update associations in other models
# ... update files ...
update_refactoring_progress "Payment" "app/models/account.rb"

# Step 4: Update controller
mv app/controllers/payments_controller.rb app/controllers/transactions_controller.rb
# ... update class name and references ...
update_refactoring_progress "Payment" "app/controllers/transactions_controller.rb"

# Step 5: Update views, specs, factories, routes
# ... update all remaining files ...

# Step 6: Validate completeness
validate_refactoring "Payment" "Transaction"

if [ $? -eq 0 ]; then
  echo "✅ Refactoring complete"
else
  echo "❌ Refactoring incomplete, fix remaining references"
fi

3. Cross-Layer Impact Checklists

Class Rename Checklist

When renaming Payment → Transaction:

Ruby Layer:

• Model class definition
• Associations in other models (has_many:payments)
• Controller class name
• Controller instance variables (@payment)
• Service class references
• Job class references
• Serializer references
• String references (polymorphic: "Payment")

View Layer:

• View template paths (app/views/payments/)
• View helpers and form objects
• Partials and layouts

Routes:

• Route resources (resources:payments)
• Named routes and path helpers

Tests:

• Spec describe blocks
• Factory definitions (:payment, :payments)
• Fixtures (if used)

JavaScript/Frontend:

• Stimulus controllers (payment_controller.js)
• Stimulus class names (PaymentController)
• data-controller attributes (data-controller="payment")
• data-action attributes (data-action="payment#submit")
• JavaScript imports and references
• Event names (payment:updated)
• Turbo frame IDs (#payment-form)
• Importmap pins

I18n:

• Locale keys (activerecord.models.payment)

Configuration:

• Initializer references
• Environment configs

Attribute Rename Checklist

When renaming user_id → account_id:

Database:

• Migration (column rename)
• Run migration: rails db:migrate
• Verify in schema.rb

Model:

• Attribute references
• Validations
• Associations (:foreign_key option)
• Scopes and queries

Controller:

• Strong params

Views:

• Form fields
• Display references

Tests:

• Spec let statements
• Factory attributes

API:

• Serializer attributes
• API documentation

JavaScript:

• data-{controller}-{attr}-value attributes
• Stimulus value definitions

I18n:

• Attribute keys (activerecord.attributes.model.user_id)

Table Rename Checklist

When renaming payments → transactions:

• Migration (table rename)
• Run migration: rails db:migrate
• Verify in schema.rb
• Model table_name declaration (if explicit)
• Foreign key constraints
• Indexes
• Raw SQL queries
• Database views (if any)

JavaScript/Stimulus Refactoring Checklist

When renaming payment → transaction in frontend:

• Controller file rename (payment_controller.js → transaction_controller.js)
• Controller class name (PaymentController → TransactionController)
• data-controller attributes in views
• data-{controller}-target attributes
• data-action attributes
• JavaScript imports
• Event names and dispatching
• CSS class names that reference the controller
• Turbo frame IDs
• Importmap pins

Namespace/Module Move Checklist

When moving Services::Payment → Billing::Transaction:

• File path (app/services/payment.rb → app/billing/transaction.rb)
• Module/namespace declaration
• All references to the old namespace
• Autoload paths (if custom)
• Spec file path
• Factory namespace
• Route namespace (if applicable)

4. Intentional Legacy References

Create .refactorignore to exclude files from validation:

# .refactorignore - Files to exclude from refactoring validation

# Legacy compatibility layer
lib/legacy_api_adapter.rb

# Historical documentation
CHANGELOG.md
docs/migration_guide.md

# Rename migrations (reference old names by design)
db/migrate/*_rename_*.rb

# External API contracts (can't change)
app/serializers/api/v1/*_serializer.rb

5. Integration with Beads

Refactoring workflow integrates with beads for:

1. Task Tracking: Creates comments for start, progress, completion
2. Status Updates: Sets task to blocked if validation fails
3. Audit Trail: Full history of what was changed and when

# Set TASK_ID before starting refactoring
export TASK_ID="PROJ-123"

# All functions will automatically log to beads
record_refactoring "Payment" "Transaction" "class_rename"
update_refactoring_progress "Payment" "app/models/transaction.rb"
validate_refactoring "Payment" "Transaction"
