SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Spec-Driven Development (SDD) ensures teams generate a complete, verifiable spec package before implementation, reducing rework and scope creep.

Core Features & Use Cases

  • Structured, phase-driven workflows: Discovery, SPEC, REQUIREMENTS, DESIGN, TEST-PLAN, TASKS, REVIEW-FINAL, START.
  • Automated governance: Gatekeeping with a senior spec-reviewer to ensure consistency and completeness.
  • Documentation-first handoff: Outputs a complete spec package that a separate implementation session can execute from START.

Quick Start

Instruct the agent to trigger spec-creation for a feature you want to develop and follow the phase-by-phase prompts to generate a complete spec package.

FAQPage Schema
What is spec-driven development and how does it prevent scope creep?

Spec-driven development generates a complete, verifiable specification package before implementation begins, ensuring teams define features thoroughly to reduce rework and scope creep.

How do I generate a complete software specification package before writing code?

Trigger spec-creation for your feature and follow phase-by-phase prompts through Discovery, SPEC, REQUIREMENTS, DESIGN, TEST-PLAN, TASKS, REVIEW-FINAL, and START to generate the package.

Can I use an automated workflow to enforce gated reviews during software documentation?

Yes, the workflow applies automated governance using a senior spec-reviewer to gatekeep phases, ensuring consistency and completeness before allowing explicit handoffs between them.

What's the best way to structure feature discovery and requirements documentation?

Structure feature discovery using a phase-driven workflow that moves sequentially from Discovery to REQUIREMENTS, producing documentation-first handoffs that ensure traceability and quality.

Does spec-driven development require any specific frameworks or dependencies to run?

No, spec-driven development operates with no external dependencies, requiring only an agent instructed to trigger spec-creation and follow the structured phase prompts.

When should I not use a phase-driven specification workflow for my project?

Avoid phase-driven specification workflows if your project requires immediate code output without upfront documentation, as this process enforces structured discovery and gated reviews before implementation.
