What problem does it solve? Teams adopting spec-driven development (SDD) often struggle to learn the workflow because tutorials use toy examples instead of real code. This Skill teaches the full SDD cycle by executing it live on the user's actual codebase, producing real artifacts and a real code change. ## Core Features & Use Cases - Guided Full-Cycle Walkthrough: Narrates and executes all SDD phases — explore, propose, spec, design, tasks, apply, verify, and archive — with short explanations at each step. - Real Change Selection: Scans the codebase for small, low-risk, spec-worthy improvements (missing validation, inconsistent error messages, extractable utilities) and lets the user pick one. - Artifact Generation: Creates production-quality proposal.md, delta specs with Given/When/Then scenarios, design.md, and tasks.md, then archives the change into the main specs. - Use Case: A developer new to SDD runs the onboarding, picks "add input validation to the contact form endpoint," and ends the session with a complete change folder, implemented code, verified spec compliance, and archived specs. ## Quick Start Ask the orchestrator to launch the SDD onboarding walkthrough so it can scan your codebase and guide you through a complete spec-driven change.
