What problem does it solve? New users of spec-driven development (SDD) often struggle to understand how the full workflow fits together, from exploration to archiving. This Skill teaches the entire SDD cycle by executing a real, small improvement on the user's actual codebase, narrating each phase so users learn by doing rather than reading documentation. ## Core Features & Use Cases - Guided End-to-End Walkthrough: Runs all SDD phases (explore, propose, spec, design, tasks, apply, verify, archive) with short narrated explanations of what each step does and why. - Real Change Selection: Scans the codebase for small, low-risk, spec-worthy improvements such as missing input validation, inconsistent error messages, or TODO comments, and presents options for the user to choose. - Artifact Production: Creates production-quality proposal.md, delta specs, design.md, and tasks.md following the formats of the individual sdd-* skills, then implements and verifies the change. - Use Case: A developer new to SDD launches the onboarding flow; the agent finds a missing loading state in an async component, builds the full artifact set, implements it with TDD narration, verifies against spec scenarios, and archives the change. ## Quick Start Ask the orchestrator to launch the sdd-onboard skill to walk you through a complete SDD cycle using a small improvement in your current codebase.
