## Remarks Protects both behavior parity across implementations and tenant isolation. ## Constructors ### AgentSkillStoreContract\(\) ```csharp protected AgentSkillStoreContract() ``` ## Methods ### CountAsync\(string, CancellationToken\) Reports how many records the given tenant sees through the listing endpoint. ```csharp protected override ValueTask CountAsync(string tenantId, CancellationToken cancellationToken) ``` #### Parameters `tenantId` [string](https://learn.microsoft.com/dotnet/api/system.string) The reading tenant. `cancellationToken` [CancellationToken](https://learn.microsoft.com/dotnet/api/system.threading.cancellationtoken) The token every store call inside the hook must be handed; see [TenantIsolationContract.SeedAsync](/api/tracon.testing.contracts.storage/). #### Returns [ValueTask](https://learn.microsoft.com/dotnet/api/system.threading.tasks.valuetask\-1)<[int](https://learn.microsoft.com/dotnet/api/system.int32)\> The number of records seen. ### Deleting\_a\_missing\_record\_returns\_false\(\) ```csharp [Fact] public Task Deleting_a_missing_record_returns_false() ``` #### Returns [Task](https://learn.microsoft.com/dotnet/api/system.threading.tasks.task) ### Disabled\_skill\_reads\_back\_disabled\(\) ```csharp [Fact] public Task Disabled_skill_reads_back_disabled() ``` #### Returns [Task](https://learn.microsoft.com/dotnet/api/system.threading.tasks.task) ### ExistsAsync\(string, object\) Reports whether the record is visible from the given tenant's viewpoint. ```csharp protected override ValueTask ExistsAsync(string tenantId, object key) ``` #### Parameters `tenantId` [string](https://learn.microsoft.com/dotnet/api/system.string) The reading tenant. `key` [object](https://learn.microsoft.com/dotnet/api/system.object) The key returned by [TenantIsolationContract.SeedAsync](/api/tracon.testing.contracts.storage/). #### Returns [ValueTask](https://learn.microsoft.com/dotnet/api/system.threading.tasks.valuetask\-1)<[bool](https://learn.microsoft.com/dotnet/api/system.boolean)\> [true](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool) if the record is visible. ### List\_is\_sorted\_by\_name\(\) ```csharp [Fact] public Task List_is_sorted_by_name() ``` #### Returns [Task](https://learn.microsoft.com/dotnet/api/system.threading.tasks.task) ### Missing\_skill\_returns\_null\(\) ```csharp [Fact] public Task Missing_skill_returns_null() ``` #### Returns [Task](https://learn.microsoft.com/dotnet/api/system.threading.tasks.task) ### Saved\_skill\_is\_read\_back\(\) ```csharp [Fact] public Task Saved_skill_is_read_back() ``` #### Returns [Task](https://learn.microsoft.com/dotnet/api/system.threading.tasks.task) ### Saving\_the\_same\_name\_again\_increments\_version\(\) ```csharp [Fact] public Task Saving_the_same_name_again_increments_version() ``` #### Returns [Task](https://learn.microsoft.com/dotnet/api/system.threading.tasks.task) ### SeedAsync\(string, string, CancellationToken\) Writes a sample record for the given tenant. ```csharp protected override ValueTask SeedAsync(string tenantId, string name, CancellationToken cancellationToken) ``` #### Parameters `tenantId` [string](https://learn.microsoft.com/dotnet/api/system.string) The tenant that owns the record. `name` [string](https://learn.microsoft.com/dotnet/api/system.string) The name distinguishing the record. The same name may be used by two tenants. `cancellationToken` [CancellationToken](https://learn.microsoft.com/dotnet/api/system.threading.cancellationtoken) The token every store call inside the hook must be handed. The cancellation contract calls this hook with a token that is already cancelled, so a hook that drops the token reports a store as sound when it is not. #### Returns [ValueTask](https://learn.microsoft.com/dotnet/api/system.threading.tasks.valuetask\-1)<[object](https://learn.microsoft.com/dotnet/api/system.object)\> The key to use for reading the record back. ### TryDeleteAsync\(string, object\) Attempts to delete the record on behalf of the given tenant. ```csharp protected override ValueTask TryDeleteAsync(string tenantId, object key) ``` #### Parameters `tenantId` [string](https://learn.microsoft.com/dotnet/api/system.string) The tenant attempting the delete. `key` [object](https://learn.microsoft.com/dotnet/api/system.object) The key returned by [TenantIsolationContract.SeedAsync](/api/tracon.testing.contracts.storage/). #### Returns [ValueTask](https://learn.microsoft.com/dotnet/api/system.threading.tasks.valuetask\-1)<[bool](https://learn.microsoft.com/dotnet/api/system.boolean)?\> [true](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool) if the delete succeeded, [false](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool) if the record was not found; [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null) if the store does not offer deletion.
