Quick Review

This is a well-structured skill for accessing the European Nucleotide Archive. The description clearly articulates when and how to use the skill, covering multiple access methods (API, FTP), data types (sequences, raw reads, assemblies), and common bioinformatics use cases. Code examples demonstrate practical implementation patterns, and the skill appropriately references api_reference.md for detailed endpoint documentation. The structure is logical with clear sections for capabilities, use cases, and best practices. The skill provides significant value by consolidating ENA's multiple APIs and complex data hierarchy into a unified interface, which would be challenging for a CLI agent to navigate efficiently without this guidance. Minor improvements could include more concrete error handling patterns and additional cross-database integration examples, but overall this is a high-quality, production-ready skill for genomics workflows.
