Define database models and schemas with proper data types, constraints, relationships, and validation rules. Use this skill when creating or modifying database models, ORM entities, schema definitions, or data validation layers. When working on Prisma schema files, TypeORM entities, Drizzle schema definitions, Mongoose models, database model classes, files defining table structures and relationships, validation schemas for database entities, or files implementing data integrity constraints and cascading behaviors.

Generate production notes defining song structure, hooks, instrumentation hints, per-section tags, and mix parameters. Aligns with style spec and blueprint production guidelines. Use when creating arrangement, dynamics, and audio engineering guidance for composition and rendering.

Technical Architect & Delivery Strategist who synthesizes product requirements and UI/UX designs into clear, actionable Technical Design Documents (TDD). Translates business flows into concrete system architecture and implementation plans. Defines end-to-end implementation paths with well-scoped phases and clear responsibility assignments. Specifies frontend-backend contracts (APIs, events, payloads, states, error models). Documents data models, integrations, security, and non-functional requirements. Explains happy paths and failure scenarios including edge cases, retries, fallbacks, and recovery. Enables confident implementation and smooth collaboration. Use when creating technical specifications, designing system architecture, planning implementation, defining APIs, or translating design into engineering work.

Design and build reusable, composable UI components following single responsibility principle with clear interfaces and proper state management. Use this skill when creating React components, Vue components, or other framework components, defining component props and interfaces, managing component state, building reusable UI elements, working with component files (*.tsx, *.jsx, *.vue, *.svelte, components/*, ui/*), implementing component composition patterns, encapsulating component logic, documenting component APIs, keeping state local or lifting it up when needed, designing component hierarchies, or refactoring monolithic components into smaller pieces. Apply this skill when building new components, refactoring existing component structures, reviewing component design patterns, or ensuring components are maintainable and reusable.

Use when preparing to fine-tune an LLM for multi-turn conversations, before generating any training data. Triggers - starting a fine-tuning project, need to define evaluation criteria, designing conversation data generation.

Domain-specific configuration profiles for learning resource creation. Defines search strategies, special fields, terminology policies, and content structures for different academic domains: technology, history, science, arts, and general. Use when researcher or writer agents need domain-adapted behavior.

SRE patterns for production service reliability: SLOs, error budgets, postmortems, and incident response.Use when defining reliability targets, writing postmortems, implementing SLO alerting, or establishingon-call practices. NOT for initial service development (use scaffolding skills instead).
