description	[Implementation] Scaffold a new feature with backend and frontend components Use when this capability is needed.

[IMPORTANT] Use TaskCreate to break ALL work into small tasks BEFORE starting — including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ATTENTION ask user whether to skip.

Prerequisites: MUST ATTENTION READ before executing:

Understand Code First — HARD-GATE: Do NOT write, plan, or fix until you READ existing code.

1. Search 3+ similar patterns (grep/glob) — cite file:line evidence
2. Read existing files in target area — understand structure, base classes, conventions
3. Run python .claude/scripts/code_graph trace <file> --direction both --json when .code-graph/graph.db exists
4. Map dependencies via connections or callers_of — know what depends on your target
5. Write investigation to .ai/workspace/analysis/ for non-trivial tasks (3+ files)
6. Re-read analysis file before implementing — never work from memory alone
7. NEVER invent new patterns when existing ones work — match exactly or document deviation

BLOCKED until: - [ ] Read target files - [ ] Grep 3+ patterns - [ ] Graph trace (if graph.db exists) - [ ] Assumptions verified with evidence

Quick Summary

Goal: Scaffold a new full-stack feature with backend (entities, CQRS, controllers) and frontend (Angular components, services).

Workflow:

1. Analyze — Break down requirements, identify scope (backend/frontend/full-stack)
2. Identify — Determine target microservice and Angular app/module
3. Plan — Map out entities, commands/queries, endpoints, components, DTOs
4. Approve — Present plan, wait for explicit user approval before creating files
5. Create — Scaffold files in order: entities → application → DTOs → controllers → frontend

Key Rules:

• DO NOT proceed without explicit user approval
• Follow platform patterns from CLAUDE.md and .github/prompts/ templates
• Build order: Domain → Application → API → Frontend
• Verify with dotnet build and nx build after creation

Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).

Create a new feature: $ARGUMENTS

Steps:

1. Analyze Requirements

   • Break down the feature requirements
   • Identify the scope (backend only, frontend only, or full-stack)

2. Identify Service Location

   • Determine the appropriate microservice for backend
   • Identify the Angular app/module for frontend

3. Plan Implementation

   • Domain entities needed
   • CQRS Commands/Queries
   • API endpoints (controllers)
   • Angular components and services
   • DTOs and validation

4. Use Project Patterns

   • Reference patterns from CLAUDE.md
   • Use .github/prompts/ templates for scaffolding:
     • create-cqrs-command.prompt.md
     • create-cqrs-query.prompt.md
     • create-entity-event.prompt.md
     • create-angular-component.prompt.md
     • create-api-service.prompt.md

5. Wait for Approval

   • Present the implementation plan
   • DO NOT proceed without explicit approval

6. Create Files (After Approval) Execute in this order:

   1. Domain entities (.Domain/Entities/)
   2. Application layer (.Application/UseCaseCommands/, .Application/UseCaseQueries/)
   3. Entity DTOs (.Application/EntityDtos/)
   4. API controllers (.Api/Controllers/)
   5. Frontend components and services

7. Verify

   • Build backend: dotnet build
   • Build frontend: nx build <app-name>

Closing Reminders

• MANDATORY IMPORTANT MUST ATTENTION break work into small todo tasks using TaskCreate BEFORE starting
• MANDATORY IMPORTANT MUST ATTENTION search codebase for 3+ similar patterns before creating new code
• MANDATORY IMPORTANT MUST ATTENTION cite file:line evidence for every claim (confidence >80% to act)
• MANDATORY IMPORTANT MUST ATTENTION add a final review todo task to verify work quality
• MANDATORY IMPORTANT MUST ATTENTION validate decisions with user via AskUserQuestion — never auto-decide MANDATORY IMPORTANT MUST ATTENTION READ the following files before starting:
• MANDATORY IMPORTANT MUST ATTENTION search 3+ existing patterns and read code BEFORE any modification. Run graph trace when graph.db exists.
