ln-720-structure-migrator

Type: L2 Domain Coordinator Category: 7XX Project Bootstrap Parent: ln-700-project-bootstrap

Coordinates project restructuring to Clean Architecture. Mode-aware: delegates to workers with appropriate mode parameters based on CREATE/TRANSFORM pipeline.

Purpose & Scope

Workers

Scope boundaries:

• Analyzes current project structure (TRANSFORM) or accepts target config (CREATE)
• Generates migration plan or scaffold plan
• Delegates to specialized workers via Agent tool
• Verifies final result

Delegation Protocol

To ln-724 (Artifact Cleaner)

When to invoke: TRANSFORM mode AND platform artifacts detected (

.replit

.stackblitzrc

sandbox.config.json

glitch.json

Context:
  projectPath: /project
  skipPreview: false
Options:
  # ln-724 auto-detects platform, no need to specify
  cleanConfigFiles: true
  cleanDirectories: true
  cleanPackages: true
  cleanBuildConfig: true
  cleanCodeComments: true
  cleanGitignore: true

To ln-721 (Frontend)

Context:
  mode: SCAFFOLD | RESTRUCTURE          # From pipeline mode
  # SCAFFOLD mode:
  targetPath: /project/src/frontend
  projectName: MyApp
  # RESTRUCTURE mode:
  sourcePath: /project/client
  targetPath: /project/src/frontend
  framework: react
  features:
    - Dashboard
    - Settings
    - Profile
Options:
  # RESTRUCTURE only:
  splitMonolithicFiles: true
  extractConstants: true
  extractTypes: true
  createComponentLibrary: true

To ln-722 (Backend)

Context:
  projectName: MyApp
  targetPath: /project/src
  targetFramework: net10.0
  features:
    - Dashboard
    - Users
Options:
  createMockData: true
  addSwagger: true
  addHealthChecks: true

To ln-723 (Seed Data)

Context:
  mode: MIGRATE | GENERATE              # From pipeline mode
  targetFormat: csharp | typescript | python | json | sql
  # MIGRATE mode:
  sourceORM: auto                        # Auto-detect (drizzle/prisma/typeorm/efcore/sqlalchemy/django)
  sourcePath: /project/shared/schema.ts
  # GENERATE mode:
  entities:                              # Optional — if empty, starter template used
    - name: User
      fields: [id, name, email, role, createdAt]
    - name: Role
      fields: [id, name, description]
  targetPath: /project/src/MyApp.Api/MockData

Critical Rules

• Orchestrator Pattern: Analyze and delegate via Skill tool, do not execute transformations directly
• Mode Awareness: Pass correct mode to all workers — CREATE vs TRANSFORM determines worker behavior
• Conditional Workers: ln-724 runs ONLY in TRANSFORM mode when platform artifacts detected; SKIP otherwise
• Sequential Workers: Execute in order (ln-724 conditional → ln-721 → ln-722 → ln-723)
• Pre-flight Checks: Verify git status clean, target paths available
• No Data Loss: Copy before delete, verify before removing source (TRANSFORM mode)
• Build Verification: All builds must pass (

  npm run build

  ,

  dotnet build

  )
• Rollback Ready: Keep backup branch until verification complete (TRANSFORM mode)

Invocations:

Skill(skill: "ln-724-artifact-cleaner", args: "{projectPath}")  # TRANSFORM only, conditional
Skill(skill: "ln-721-frontend-restructure", args: "{projectPath} --mode {SCAFFOLD|RESTRUCTURE}")
Skill(skill: "ln-722-backend-generator", args: "{projectPath}")
Skill(skill: "ln-723-seed-data-generator", args: "{projectPath} --mode {GENERATE|MIGRATE}")

TodoWrite format (mandatory):

- Invoke ln-724-artifact-cleaner (conditional TRANSFORM) (pending)
- Invoke ln-721-frontend-restructure (pending)
- Invoke ln-722-backend-generator (pending)
- Invoke ln-723-seed-data-generator (pending)
- Verify structure and builds (pending)

Worker Invocation (MANDATORY)

All workers: Invoke via Skill tool — workers see coordinator context.

Definition of Done

CREATE mode:

• Target stack config received from ln-700
• ln-721 completed: Frontend scaffolded (SCAFFOLD mode)
• ln-722 completed: Backend generated
• ln-723 completed: Seed data generated (GENERATE mode)
• File structure matches target templates
• All configs valid (package.json, tsconfig.json, .csproj)

TRANSFORM mode:

• Current structure analyzed and documented
• Migration plan generated
• ln-724 completed: Platform artifacts removed (if applicable)
• ln-721 completed: Frontend restructured (RESTRUCTURE mode)
• ln-722 completed: Backend generated
• ln-723 completed: Seed data migrated (MIGRATE mode)
• Frontend builds successfully (

  npm run build

  )
• Backend builds successfully (

  dotnet build

  )
• No orphan files in old locations
• All imports resolve correctly
• Migration report generated

Risk Mitigation

git status

npm run build

dotnet build
