accountId: string

Account this resource belongs to for multi-tenant isolation (prefixed ULID)

createdAt: string

name: string

Human-readable name for the resource (e.g., “Customer Support Agent”, “Email Tool”) Required for resources that users interact with directly

profileId: string

ID of the actor (user or service account) that created this resource

workspaceId: string

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

bundleKey: optional string

Optional bundle ownership key. When set, indicates the resource is managed by a configuration bundle identified by this key. Used by BulkWorkspaceResources.Apply to track which resources belong to which 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]

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 }

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

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.
