        Workspace this resource belongs to for organizational grouping (prefixed ULID)

      - `bundleKey: optional string`

        Optional bundle ownership key. When set, indicates the resource is

        External ID for the resource (e.g., a workflow ID from an external system)

      - `labels: optional map[string]`

        Arbitrary key-value pairs for categorization and filtering
        Examples: {"environment": "production", "team": "platform", "version": "v2"}

    - `spec: object { compactionConfig, constraints, description, 6 more }`

      AgentVariationSpec defines the operational configuration for a variation

      - `compactionConfig: optional object { summarization, toolResultClearing, triggerThreshold }`

        CompactionConfig defines how context window compaction behaves for objectives using this variation.

        - `summarization: optional object { instructions }`

          SummarizationStrategy configures LLM-powered summarization of older conversation turns.

          - `instructions: optional string`

            Custom instructions that guide what the summarizer preserves.
            Replaces the default summarization prompt entirely.
            Example: "Preserve all code snippets, variable names, and technical decisions."

        - `toolResultClearing: optional object { preserveRecentResults }`

          ToolResultClearingStrategy configures clearing of older tool result content.

          - `preserveRecentResults: optional number`

            Number of most recent tool call results to keep intact.
            Older tool results have their content replaced with "[result cleared]"
            while preserving the assistant tool call message (function name, arguments).
            Default: 2

        - `triggerThreshold: optional number`

          Trigger threshold as a percentage of the model's context window (0.0 to 1.0).
          When input tokens reach this percentage of the model's limit, compaction triggers.
          Default: 0.75 (75%)

      - `constraints: optional object { maxSubObjectives, maxToolCalls }`

        Execution constraints

        - `maxSubObjectives: optional number`

          The maximum number of sub-objectives that can be created. 0 means no limit.

        - `maxToolCalls: optional number`

          The maximum number of tool calls that can be made. 0 means no limit.

      - `description: optional string`

        Human-readable description of what this variation does or when it should be used

      - `enableEpisodicMemory: optional boolean`

        Enable episodic memory for objectives using this variation.
        When true, the system automatically creates a document namespace for each objective
        using the objective's episodic_key as the external_id, allowing the agent to
        store and retrieve documents specific to that episode.

      - `episodicMemoryTtl: optional number`

        How long episodic memories should be retained.
        After this duration, episodic document namespaces can be automatically cleaned up.
        If not set, episodic memories are retained indefinitely.

      - `modelConfig: optional object { modelId, temperature }`

        ModelConfig defines the model configuration for a variation

        - `modelId: optional string`

          The model identifier in family/model format (e.g., "claude/opus-4.6", "claude/sonnet-4.5")

        - `temperature: optional number`

          Sampling temperature for model inference (0.0 to 1.0)
          Lower values produce more deterministic outputs, higher values increase randomness

      - `progressiveDiscovery: optional object { hints, maxTools, rerankThreshold }`

        ProgressiveDiscovery is used to indicate that the agent should automatically discover tools that are not explicitly assigned to it.
        Max tools is the maximum number of tools that can be discovered per search.
        Hints are optional hints for tool search. These are used in conjunction with the context-aware tool search and can help select the best tools for the task.

        - `hints: optional array of string`

        - `maxTools: optional number`

        - `rerankThreshold: optional number`

          Rerank Threshold is an optional value that instructs whether or not to run a search result through a embedding/reranker process
          which can improve performance and reduce context bloat when tools reach the configured threshold. If a tool match must exceed 0.8, for example,
          the tool very closely match the query the tool search performed.

      - `prompt: optional string`

        The system prompt for this variation

      - `weight: optional number`

        Weight for weighted random selection (>= 0). P(v) = v.weight / sum(all_weights).
        Only used when the agent's variation_selection_mode is WEIGHTED. A weight of 0 means never auto-selected, but can still be chosen explicitly via variation_id on CreateObjectiveRequest.

    - `info: optional object { assignments, createdBy, feedbackCount, 7 more }`

      AgentVariationInfo provides read-only summary information about a variation

      - `assignments: optional array of VariationAssignment`

        All tools, tool sets, and sub-agents assigned to this variation.
        Populated on reads so clients can render a variation's full assignment
        list without calling the add/remove endpoints just to enumerate.

        - `id: optional string`

        - `agent: optional object { id, name }`

          BareMetadata contains the minimal metadata for a resource: the ID and an
          optional human-readable name. These are used for reference fields where the
          full metadata (account scoping, timestamps, labels, external IDs) is not
          needed — e.g., the tool references inside an agent variation spec or the
          tools assigned to an objective. Both fields are server-populated; clients
          provide IDs through sibling fields rather than by constructing a
          BareMetadata themselves.

          - `id: optional string`

          - `name: optional string`

            Human-readable name of the referenced resource, populated by the server

          needed — e.g., the tool references inside an agent variation spec or the
          tools assigned to an objective. Both fields are server-populated; clients
          provide IDs through sibling fields rather than by constructing a
          BareMetadata themselves.

          - `id: optional string`

          - `name: optional string`

            Human-readable name of the referenced resource, populated by the server

          needed — e.g., the tool references inside an agent variation spec or the
          tools assigned to an objective. Both fields are server-populated; clients
          provide IDs through sibling fields rather than by constructing a
          BareMetadata themselves.

          - `id: optional string`

          - `name: optional string`

            Human-readable name of the referenced resource, populated by the server

      - `createdBy: optional object { metadata, spec }`

        A profile identifies a user or non-human principal (such as an API key)
        at the account level. Profiles are account-scoped and can be granted access
        to multiple workspaces.

        returned in ascending `position` (bottom → top). Capped at 10 entries.

        - `id: optional string`

          Assignment row id — handle for removing the assignment. Distinct
          from the referenced memory layer's id.

        - `memoryLayer: optional object { id, name }`

          BareMetadata contains the minimal metadata for a resource: the ID and an
          optional human-readable name. These are used for reference fields where the
          full metadata (account scoping, timestamps, labels, external IDs) is not
          needed — e.g., the tool references inside an agent variation spec or the
          tools assigned to an objective. Both fields are server-populated; clients
          provide IDs through sibling fields rather than by constructing a
          BareMetadata themselves.

          - `id: optional string`

          - `name: optional string`

            Human-readable name of the referenced resource, populated by the server
            on reads for convenience. Absent on references to resources that do not
            have a name (e.g., objective tasks).

        - `position: optional number`

          Position in the variation's baseline stack. Lower values sit lower;
          the highest-position assignment is on top of the variation's
          baseline. Gaps are fine — only relative position matters. Positions
          must be unique within a variation; a request that would collide
          with an existing assignment's position is rejected with
          InvalidArgument.

          bundle for reconciliation / soft-delete on re-apply.

        - `externalId: optional string`

          External ID for the resource (e.g., a workflow ID from an external system)

        - `labels: optional map[string]`
