What is the primary benefit of using the SDD Workflow skill?

It prevents rework and technical debt by ensuring requirements are fully specified and architecturally planned before any code is written, followed by automated validation.

What are the different rigor levels available?

It supports 'spec-first' (initial guidance), 'spec-anchored' (maintained synchronization), and 'spec-as-source' (code generated from spec) to match different project lifecycle needs.

Does it support small changes or just large features?

It includes a 'Lightweight Mode' specifically designed for bug fixes and minor tweaks, which streamlines the process by focusing on acceptance criteria and skipping formal planning.

How does the skill handle interrupted sessions?

The skill persists all artifacts (specs, plans, and reports) to your local filesystem and automatically detects them to resume from the correct phase in any future session.

Can I skip the specification phase if I am in a hurry?

While the skill strongly recommends specifying first to reduce errors, it allows you to skip phases if you explicitly insist, though it will note the potential risks of doing so.

Productivity & Workflow

Orchestrates the complete spec-driven development lifecycle through specification, planning, implementation, and validation phases.

This skill provides a structured framework for Spec-Driven Development (SDD) within Claude Code, ensuring that features are well-defined and architected before implementation begins. By guiding users through four distinct phases—Specify, Plan, Implement, and Validate—it minimizes rework and maintains high code quality. The workflow intelligently adapts to project needs with three rigor levels and a lightweight mode for smaller changes, while persisting all progress as markdown files to ensure seamless continuity across development sessions.
