event-store-design

Quick Review

This is a high-quality skill that comprehensively covers event store design and implementation. The description clearly indicates when to use the skill (building event sourcing infrastructure, choosing technologies, implementing persistence patterns). Task knowledge is excellent with concrete templates for PostgreSQL, Python implementations, EventStoreDB, and DynamoDB, plus schema designs and best practices. Structure is clear with logical sections covering concepts, comparisons, templates, and practices. Novelty is good - while a CLI agent could research event stores, consolidating this knowledge (concurrency control, subscription patterns, multiple technology stacks) meaningfully reduces token usage and avoids scattered documentation searches. The skill provides production-ready code that would be time-consuming to assemble from scratch. Minor improvement area: could add more on scaling patterns and operational considerations, but current content is comprehensive and immediately actionable.
