Coding-agent skill

Install the guidance shipped with ark_data_layer:

dart run skills@ get -p ark_data_layer

The installed ark-data-layer-repository-implementation skill helps an agent:

• keep technical clients behind typed DataSource contracts;
• normalize source output into business data owned by a Repository;
• choose strict source lookup and explicit source ownership;
• preserve replay-latest observation, mutation, and close semantics;
• review boundaries without moving business rules into infrastructure code.

The skill is development guidance, not runtime code. It does not generate a Repository, choose a storage client, or replace the package documentation and application requirements. Review it before use and reinstall it after upgrading the package.
