SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Creates a clear, agreed-upon specification before starting code, preventing guesswork and rework when requirements are unclear or evolving.

Core Features & Use Cases

Structured six-section spec covering objective, commands, project structure, code style, testing strategy, and boundaries.
Early risk and assumption surfacing to surface misalignments before implementation.
Use Case: starting a new project with ambiguous requirements; architectural decisions; multi-file changes; scope changes.

Quick Start

Create a Spec document outlining objective, assumptions, commands, project structure, and success criteria before coding.

FAQPage Schema

How do I create a specification before coding to prevent rework?▼

To create a specification before coding, structure a six-section document covering objective, commands, project structure, code style, testing, and boundaries. This living spec enforces a four-phase workflow: Specify, Plan, Tasks, and Implement, preventing guesswork.

When do I need to use spec-driven development for my project?▼

You need spec-driven development when requirements are unclear, evolving, or span multiple modules. It is particularly useful for architectural decisions and multi-file changes, ensuring early risk and assumption surfacing before implementation begins.

What is the best way to plan architecture for multi-file changes?▼

The best way to plan architecture for multi-file changes is applying a structured specification workflow. By defining project structure, code style, and boundaries in a version-controlled spec, you surface misalignments and establish clear success criteria before executing tasks.

Can I use a version-controlled spec for evolving project requirements?▼

Yes, you can use a version-controlled spec for evolving requirements. It acts as a living document that guides execution through Specify, Plan, Tasks, and Implement phases, allowing you to adapt to scope changes without losing alignment.

How does a specification workflow handle ambiguous project requirements?▼

A specification workflow handles ambiguous requirements by forcing early documentation of objectives and assumptions. This process creates an agreed-upon plan covering testing strategy and boundaries, which prevents guesswork and reduces rework during the implementation phase.

What are the limitations of spec-driven development for software engineering?▼

The limitation of spec-driven development is the overhead required to maintain a living, version-controlled spec. Projects with single-file changes or fully defined requirements may find the four-phase workflow unnecessary, as it focuses on surfacing architectural risks before implementation.
