A credential that belongs to a specific Workspace may omit it; if sent, it must match that Workspace. ## Returns - `class ResourceRetrieveResponse: union` The requested session resource. - `class BetaManagedAgentsGitHubRepositoryResource` - `JsonElement Type = "github_repository"` - `required string ID` - `required DateTimeOffset CreatedAt` A timestamp in RFC 3339 format format: date-time - `required string MountPath` - `required DateTimeOffset UpdatedAt` A timestamp in RFC 3339 format format: date-time - `required string Url` - `Checkout? Checkout` - `class BetaManagedAgentsBranchCheckout` - `JsonElement Type = "branch"` - `required string Name` Branch name to check out. minLength: 1, maxLength: 255 - `class BetaManagedAgentsCommitCheckout` - `JsonElement Type = "commit"` - `required string Sha` Full commit SHA to check out. minLength: 7, maxLength: 64, pattern: ^[0-9a-fA-F]+$ - `class BetaManagedAgentsFileResource` - `JsonElement Type = "file"` - `required string ID` - `required DateTimeOffset CreatedAt` A timestamp in RFC 3339 format format: date-time - `required string FileID` - `required string MountPath` - `required DateTimeOffset UpdatedAt` A timestamp in RFC 3339 format format: date-time - `class BetaManagedAgentsMemoryStoreResource` A memory store attached to an agent session. - `JsonElement Type = "memory_store"` - `required string MemoryStoreID` The memory store ID (memstore_...). Must belong to the caller's organization and workspace. pattern: ^memstore_[a-zA-Z0-9_]+$ - `Access? Access` Access mode for the mounted store. Defaults to `read_write`. `read_only` mounts the store as a read-only filesystem. - `ReadWrite("read_write")` - `ReadOnly("read_only")` - `string Description` Description of the memory store, snapshotted at attach time. Rendered into the agent's system prompt. Empty string when the store has no description. - `string? Instructions` Per-attachment guidance for the agent on how to use this store. Rendered into the memory section of the system prompt. Max 4096 chars. maxLength: 4096 - `string? MountPath` Filesystem path where the store is mounted in the session container, e.g. /mnt/memory/user-preferences. Derived from the store's name. Output-only. - `string? Name` Display name of the memory store, snapshotted at attach time. Later edits to the store's name do not propagate to this resource. ## Example ```csharp using System; using Anthropic.Models.Beta.Sessions.Resources; ResourceRetrieveParams parameters = new() { SessionID = "sesn_011CZkZAtmR3yMPDzynEDxu7", ResourceID = "sesrsc_011CZkZBJq5dWxk9fVLNcPht", }; var resource = await client.Beta.Sessions.Resources.Retrieve(parameters); Console.WriteLine(resource); ``` ### Response (200) ```json { "id": "sesrsc_011CZkZCKr6eXym1gWMPdQiu", "created_at": "2026-03-15T10:00:00Z", "mount_path": "/workspace/example-repo", "type": "github_repository", "updated_at": "2026-03-15T10:00:00Z", "url": "https://github.com/example-org/example-repo", "checkout": { "name": "main", "type": "branch" } } ```
