SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill solves the complexity of managing multi-agent workflows for full-stack application development by providing a structured, template-driven orchestration layer.

Core Features & Use Cases

  • Automated Scaffolding: Instantly generates project structures for 13+ tech stacks including Next.js, FastAPI, and Flutter.
  • Agent Coordination: Enforces a mandatory planning phase and manages the handoff between specialized agents like Database Architects and DevOps Engineers.
  • Use Case: When a user requests a new SaaS product, the Skill automatically selects the Next.js + Stripe template, triggers the project planner, and ensures the database schema is defined before any frontend code is written.

Quick Start

Use the app-builder skill to create a new full-stack SaaS application with Next.js and Stripe.

FAQPage Schema
How do I orchestrate full-stack app development across multiple specialized agents?

Full-stack app development orchestration is managed by analyzing natural language requirements, selecting project templates, and coordinating specialized agents for database design, backend logic, frontend components, and deployment. The workflow enforces strict planning and verification checkpoints before generating any code.

What is the best way to automate scaffolding for a Next.js SaaS application?

Automating scaffolding for a Next.js SaaS application involves selecting a Next.js + Stripe template from over 13 supported tech stacks. The orchestration layer automatically triggers the project planner and ensures the database schema is defined before any frontend code is built.

Does multi-agent workflow orchestration support project templates beyond Next.js?

Multi-agent workflow orchestration supports project templates for over 13 tech stacks, including Next.js, FastAPI, and Flutter. It automatically selects the appropriate template based on your natural language requirements before initiating the execution pipeline.

How do I ensure database schemas are defined before frontend code is generated?

To ensure database schemas are defined before frontend code generation, the orchestration pipeline enforces a mandatory planning phase. It manages handoffs to specialized agents like the Database Architect, verifying project checkpoints before any frontend components are built.

Can I use automated scaffolding to coordinate a DevOps Engineer agent for deployment?

Automated scaffolding coordinates a DevOps Engineer agent for deployment by managing the execution pipeline across specialized roles. It ensures the backend logic and frontend components pass verification checkpoints before triggering the deployment phase.

When should I not use a template-driven orchestration layer for application development?

A template-driven orchestration layer should not be used when your full-stack application requirements fall outside the 13 supported tech stacks or when you need to bypass the mandatory planning phase and strict verification checkpoints before code generation.
