SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill eliminates the manual overhead of creating consistent technical design documentation by automating the generation of research, data models, and interface contracts based on project-specific requirements.

Core Features & Use Cases

  • Automated Workflow Orchestration: Executes a structured planning process including research, data modeling, and contract definition.
  • Constitution Enforcement: Validates design artifacts against project-specific architectural constraints and rules.
  • Use Case: When starting a new feature, use this Skill to automatically generate a research document, define the data model, and create interface contracts, ensuring all technical unknowns are addressed before implementation begins.

Quick Start

Invoke the speckit-plan skill to initiate the design workflow for the current feature specification.

FAQPage Schema
How do I automate technical planning and design document generation?

To automate technical planning and design document generation, use this Skill to orchestrate workflows that produce research documents, data models, and interface contracts based on your project-specific requirements.

What is the best way to generate interface contracts and data models before implementation?

Generating interface contracts and data models before implementation is best handled by automating a structured planning process. This defines data structures and validates architectural constraints early to address technical unknowns.

Do I need a specific directory structure to automate architectural validation?

Yes, automating architectural validation requires a project structure containing a .specify directory. This enforces project-specific architectural constraints and rules during the design artifact generation process.

Can I use Python to orchestrate software engineering workflows for research documents?

Yes, you can use Python to orchestrate software engineering workflows for research documents. A configured Python environment is required to execute the automated generation of technical design artifacts.

Why validate design artifacts against architectural constraints before coding?

Validating design artifacts against architectural constraints before coding ensures constitution enforcement across your project. This prevents architectural drift by checking generated data models and interface contracts against established rules.
