Api Filtering Sorting

This handles the classic API filtering and sorting problem: turning query parameters into safe, performant database queries. You get query parsing, field whitelisting, and validation patterns for MongoDB, SQLAlchemy, and Elasticsearch. The skill covers the whole chain from parsing ?category=shoes&minPrice=50 to building optimized database queries without opening yourself up to injection attacks. Most useful when you're building search interfaces or flexible data APIs and don't want to reinvent parameter parsing for the hundredth time. The reference guides include a filter builder pattern and faceted navigation examples, which beats cobbling together regex parsers and hoping for the best.
