How does this help with DynamoDB single-table design?

It provides standardized patterns for mapping multiple entities to a single table using generic PK/SK attributes and derived keys for various access patterns.

Is the generated code fully type-safe?

Yes, it utilizes dynamodb-toolbox's inference capabilities to provide distinct types for input data (writes) and formatted data (reads), ensuring compile-time safety.

Does this skill support dynamodb-toolbox v1?

This skill is specifically designed for the v2 syntax of dynamodb-toolbox, which offers enhanced type safety and improved schema definition patterns over previous versions.

Can it help with complex queries and pagination?

Absolutely. It includes patterns for GSI queries, range-key filtering (beginsWith, etc.), and encoding/decoding LastEvaluatedKeys into URL-safe pagination tokens.
