When working with JSON data in LLM prompts (especially large arrays or tabular data), consider the token-efficient TOON (Token-Oriented Object Notation) format which reduces tokens by 30-70% while maintaining lossless JSON representation and structural validation. Use for reading/writing .toon files, converting JSON↔TOON, or optimizing structured data for LLM consumption with guardrails like [N] counts and {field} headers.

Write efficient, secure database queries using ORMs or raw SQL, preventing N+1 problems, SQL injection, and performance issues. Use this skill when writing database queries, implementing data access layers, creating repository patterns, or optimizing query performance in service files, query builders, or data access objects. Apply this skill when using parameterized queries, implementing eager loading to avoid N+1 queries, selecting only needed columns, adding WHERE/JOIN/ORDER BY clauses, or working with query optimization, indexes, and database performance tuning. This skill ensures queries use proper SQL injection prevention, implement transactions for data consistency, cache expensive queries appropriately, and follow best practices for query timeouts, connection pooling, and database resource management.
