How does the /speckit.specify command help in development?

The /speckit.specify command takes a natural language feature description and generates a complete specification file (spec.md) including user scenarios, functional requirements, and success criteria, focusing on 'what' is needed rather than 'how' to build it.

Is Spec Kit compatible with existing projects?

Absolutely. Spec Kit is designed to work within your existing project structure, storing specifications in a dedicated specs/ folder and referencing your current tech stack for planning.

Can I use Spec Kit to enforce specific coding standards?

Yes. By defining a project constitution at memory/constitution.md, the toolkit will automatically validate implementation plans against your architectural gates, such as simplicity, testing requirements, or specific framework usage.

What kind of output does /speckit.tasks provide?

It generates a task list (tasks.md) organized by phases and user story priority. It includes task IDs, dependency ordering, and marks tasks that can be executed in parallel to optimize the build process.

What is Specification-Driven Development (SDD)?

SDD is a development methodology where specifications drive the code. Instead of specs being documentation for existing code, code becomes the expression of specifications, ensuring the implementation perfectly matches the initial intent.

Spec Kit SDD Toolkit | Claude Code Skill for Feature Planning

Spec Kit is a specialized toolkit for Claude Code designed to implement Specification-Driven Development (SDD), a methodology where specifications act as the primary source of truth for the codebase. It provides a structured workflow to bridge the gap between initial concepts and final implementation by generating comprehensive feature specs, architectural plans, and actionable task lists. By utilizing customizable templates and 'Project Constitutions,' Spec Kit ensures that AI-driven development remains architecturally sound, testable, and aligned with organizational standards, significantly reducing ambiguity during the development lifecycle.
