Sdd Skill

Spec-Driven Development (SDD) Skill

A comprehensive Claude Code skill for guiding users through GitHub's Spec-Kit and the Spec-Driven Development methodology.

What is Spec-Driven Development?

Spec-Driven Development flips traditional software development on its head. Instead of treating specifications as temporary scaffolding, SDD makes them executable - they directly generate working implementations rather than just guiding them.

What's New in v2.1.0

🎯 Enhanced Explanations & Summaries
- 10-Point Summary Template: Structured summaries after every SDD command showing key decisions, what was generated, items to review, watch-outs, and next steps
- Rationale for Decisions: Every major decision includes "why" it was made
- No More Black Boxes: Clear explanations eliminate the mystery of what was just generated

📊 Feature Status Tracking
- Automatic Progress Tracking: See exactly where each feature is (Specified, Planned, Tasked, In Progress, Complete)
- Hybrid Status Display: Brief status line in every summary + detailed dashboard on demand
- Dependency Visualization: See what features depend on what, and what's blocking progress
- Progress Percentages: Automatic calculation based on workflow completion (20%, 40%, 60%, 80%, 100%)

💬 Natural Language Feature Management
- Add Features: Just say "Add a feature for email notifications"
- Reorder Features: "Move user-notifications before profile-management"
- Remove Features: "We don't need reporting anymore"
- Show Status: "Show me all features" or "What's blocking admin-dashboard?"
- Check Dependencies: "Can we start profile-management yet?"
