Databases

Use when designing database schemas, need to model domain entities and relationships clearly, building knowledge graphs or ontologies, creating API data models, defining system boundaries and invariants, migrating between data models, establishing taxonomies or hierarchies, user mentions "schema", "data model", "entities", "relationships", "ontology", "knowledge graph", or when scattered/inconsistent data structures need formalization.

This skill should be used when users need to fetch GitHub issues from the current repository, including getting the next issue to work on, retrieving specific issue fields (body, number, title, labels, etc.), or querying issues with custom sorting and filtering. Triggers on requests like "get the next GitHub issue", "what's the next issue number", "show me the issue body", or "find issues with label X".
