What problem does it solve? Adding a new Gallery case to the Optimization Compass knowledge base requires strict consistency with existing canonical IDs and validation rules; this Skill guides that process so contributors avoid broken references and failed PR gates. ## Core Features & Use Cases - ID Verification: Confirms every referenced ID (problem archetype, method, implementation, source, visualization, comparison) already exists in the generated indexes under site/public/data/ before editing. - Guided Editing: Copies the structurally closest existing case in data/seeds/site_gallery.json and re-evaluates every copied ID rather than reusing them blindly. - Validation Workflow: Runs uv run optimization-compass validate gallery locally and validate tier-b as the PR gate, with DCO sign-off required. - Use Case: A contributor wants to document a new real-world optimization example in the Gallery; the Skill walks them through ID checks, seed editing, and validation without touching site code. ## Quick Start Add a new Gallery case for a workforce scheduling problem to the optimization-compass dataset and validate it.
