The instruction file, verbatim from the audited commit — this is the text the model reads, and the surface the audit's instruction layer examines. Quoted here so you can judge it without cloning anything.
--- name: cosmos-provider description: 'Implementation details for the EF Core Azure Cosmos DB provider. Use when changing Cosmos-specific code.' user-invocable: false --- # Cosmos DB Provider Non-relational provider with its own parallel query pipeline. Uses JSON for document materialization. ## Key Differences from Relational - No migrations — use `EnsureCreated()` - Documents as JSON — owned and complex types become embedded objects - Partition key configuration required for performance - `ETag` for optimistic concurrency - No cross-container joins ## Azure Cosmos DB Emulator for Tests - `TestEnvironment.InitializeAsync()` auto-starts a `Testcontainers.CosmosDb` container when `Test__Cosmos__DefaultConnection` is not set. Set the env var to use an existing emulator instead. - Skip tests requiring unsupported features on the Linux emulator with ` [ConditionalFact(typeof(CosmosTestEnvironment), nameof(CosmosTestEnvironment.IsNotLinuxEmulator))]`.

Questions
What does the Cosmos Provider skill do?

What can Cosmos Provider access on my machine?
The audit observed no filesystem, network or shell use at all in its source.
