Database
Database management and queries
normalized
by Semprini
Use this skill when the user asks for a normalized operational model, practical/pragmatic 3NF, OLTP schema design, or non-dimensional physical outputs. Also use when producing database DDL, JSON Schema, or Parquet-oriented schema contracts from MD-DDL.
avoiding-sql-antipatterns
by sumik5
Identifies and prevents common SQL database design mistakes across logical design, physical design, query construction, and application development. Use when designing database schemas, writing SQL queries, reviewing data models, or implementing database-backed features. Covers 25 named antipatterns with detection signals, solutions, and exception cases. For code-level security (input validation, XSS, OWASP), use securing-code instead. For database model selection and data architecture decisions, use understanding-database-internals instead. For positive relational database design methodology (entity modeling, normalization process), use designing-relational-databases instead.
postgres

Connect to Postgres databases, run queries/diagnostics, and search official PostgreSQL docs only when explicitly requested.
architecting-data
by sumik5
Data architecture patterns covering read-side optimization (replicas, materialized views, CQRS, CDC, event sourcing), domain-based decomposition, polyglot persistence, and caching strategies (cache-aside, read-through, write-through, write-around). Use when designing data flow architecture, choosing read scalability strategies, or implementing caching for enterprise systems. For microservices patterns (Saga, granularity), use architecting-microservices instead. For DDD domain modeling, use applying-domain-driven-design instead. For database engine internals, use understanding-database-internals instead. For relational DB schema design, use designing-relational-databases instead. For GCP-specific data services (BigQuery, Dataflow, Dataproc), use developing-google-cloud instead.

dimensional
by Semprini
Use this skill when the user asks for a physical dimensional model, star schema, fact/dimension design, bridge strategy. Also use when deciding how existence, mutability, and temporal tracking should influence physical realization.
agno
by AbhishekSharma-17
"Build AI agents, multi-agent teams, and agentic workflows using the Agno framework. MANDATORY TRIGGERS: Agno, agno-agi, AgentOS, any mention of the Agno framework. Also trigger when the user wants to build AI agents with tools/memory/knowledge, create multi-agent systems, RAG pipelines, reasoning agents, agentic workflows, or deploy agents to production. Trigger even if the user just says 'build me an agent', 'create an AI assistant', or 'make a chatbot' — if Agno is anywhere in their stack or project dependencies. When in doubt about whether to use this skill for agent-building tasks, use it."
angular-signals
by Kobolden
Implement signal-based reactive state management in Angular v20+. Use for creating reactive state with signal(), derived state with computed(), dependent state with linkedSignal(), and side effects with effect(). Triggers on state management questions, converting from BehaviorSubject/Observable patterns to signals, or implementing reactive data flows.

applying-domain-driven-design
by sumik5
Domain-Driven Design methodology covering strategic design (Bounded Context, Ubiquitous Language, Context Mapping), tactical patterns (Domain Model, Event Sourcing, CQRS), practical adoption (heuristics, EventStorming), and operational data decomposition with polyglot database selection. Use when designing domain boundaries, choosing business logic implementation patterns, decomposing monolithic data, or aligning software architecture with business strategy. For socio-technical architecture modernization and trade-off analysis, use modernizing-architecture instead. For microservices distributed patterns (Saga, messaging, granularity), use architecting-microservices instead. For data architecture read-side patterns and caching strategies, use architecting-data instead.
ai-coding-usage
by fairchild
Analyze AI coding assistant usage patterns across Claude Code and Cursor.
