What problem does it solve?

This Skill automates the creation of comprehensive implementation plans, including technical research, data models, API contracts, and test scenarios. It ensures designs adhere to critical constitutional principles like Library-First Architecture, Test-First Development, and Contract-First Design, preventing costly architectural mistakes and ensuring a solid foundation for development.

Core Features & Use Cases

• Automated Design Artifact Generation: Produces essential documents like research.md, data-model.md, contracts/, and quickstart.md with minimal manual input.
• Constitutional Compliance Validation: Automatically checks the plan against 14 core development principles, guaranteeing adherence to quality and architectural standards.
• Domain & Agent Identification: Detects technical domains and suggests specialist agents for the implementation phase, streamlining team allocation.
• Use Case: After defining a feature specification, use this Skill to generate a complete technical design for a "Payment Gateway Integration." It will automatically create API contracts, data models for transactions, and a comprehensive testing strategy, ensuring all design aspects are covered and compliant before a single line of code is written.
