What problem does it solve? It guides contributors through adding or enriching method and concept articles in the Optimization Compass knowledge base while keeping content consistent with canonical entities and passing repository validation gates. ## Core Features & Use Cases - Canonical entity verification: Confirms the target entity exists in generated indexes (content.json, sources.json) before writing, stopping if the entity is missing. - Article authoring workflow: Mirrors frontmatter from the nearest existing article in content/methods or content/concepts and marks incomplete work as draft. - Density and validation checks: Runs the method content density report and the optimization-compass validate content / tier-a commands before submission. - Use Case: A contributor wants to document an existing optimization method that lacks an article; the skill walks them through entity lookup, article creation, density checks, and PR validation. ## Quick Start Add a new method article for an existing canonical entity and validate it with the optimization-compass content checks.
