SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill solves the challenge of inconsistent feature development by enforcing a structured, spec-driven workflow that ensures technical alignment before any code is written.

Core Features & Use Cases

  • Automated Planning: Generates implementation plans, data models, and validation guides based on project specifications.
  • Constitution Enforcement: Validates proposed changes against the project's architectural constitution to prevent technical debt.
  • Use Case: When starting a new feature, use this Skill to automatically generate the research, data models, and task breakdown required to maintain the project's high standards of quality and test coverage.

Quick Start

Invoke the speckit-plan skill to initiate the planning phase for the current feature specification found in the specs directory.

FAQPage Schema
How do I automate feature implementation planning for spec-driven development projects?

Spec-driven development planning is automated by generating technical design artifacts, data models, and validation guides directly from project feature specifications. This structured workflow ensures technical alignment before any code is actually written.

How does constitution validation prevent technical debt during architecture planning?

Constitution validation prevents technical debt by checking proposed implementation plans against project-specific architectural constitution files and extension hooks. This enforcement mechanism ensures new features maintain established architectural standards and required test coverage.

What is the best way to generate data models and task breakdowns from feature specifications?

Generating data models and task breakdowns is best handled by orchestrating an automated planning workflow that reads feature specifications and outputs structured technical design artifacts. This enforces consistent feature development and maintains high quality standards.

Do I need a specs directory to start the spec-driven development planning workflow?

Yes, a specs directory is required to start spec-driven development planning. The workflow specifically reads the current feature specification found within this directory to automatically initiate the generation of research, data models, and validation guides.

Can I validate proposed architectural changes against custom project rules before coding?

Yes, you can validate proposed architectural changes against custom project rules. The planning workflow validates proposed changes against your project-specific architectural constitution files to prevent technical debt and ensure alignment before implementation begins.
