Properties​

agentCalls?​

optional agentCalls: AgentCallRecord[]

Defined in: packages/agentos/src/api/generateText.ts:844

Ordered records of every sub-agent call made during an agency() run. undefined for plain generateText / agent() calls.

cacheDiagnostics?​

optional cacheDiagnostics: CacheDiagnostics | null

Defined in: packages/agentos/src/api/generateText.ts:817

Cache-diagnostics verdict from the LAST agentic step (Anthropic beta; present only when the run opted in via GenerateTextOptions.cacheDiagnostics). null = the last step's request matched its predecessor (prefix stable). A populated cacheMissReason names the earliest divergence. Per-step verdicts are available on the onAfterGeneration hook.

fallback?​

optional fallback: FallbackSignal

Defined in: packages/agentos/src/api/generateText.ts:874

Per-hop provider fallback trail. fired is true when any non-primary provider produced — or was tried for — the result, so callers can flag a degraded run even when the final attempt recovered on the primary. undefined only on legacy code paths that predate the field.

finishReason​

finishReason: "error" | "length" | "stop" | "tool-calls"

Defined in: packages/agentos/src/api/generateText.ts:839

Reason the model stopped generating.

  • "stop": natural end of response.
  • "length": maxTokens limit reached.
  • "tool-calls": loop exhausted maxSteps while still calling tools.
  • "error": provider returned an error.

grounding?​

optional grounding: VerifiedResponse

Defined in: packages/agentos/src/api/generateText.ts:867

Per-claim citation verdicts attached when agent({ verifyCitations: … }) is configured. undefined when verification was not requested or could not run for this turn.

See​

import('./types.js').VerifyCitationsConfig

model​

model: string

Defined in: packages/agentos/src/api/generateText.ts:786

Resolved model identifier used for the run.

parsed?​

optional parsed: unknown

Defined in: packages/agentos/src/api/generateText.ts:854

Parsed structured output produced when BaseAgentConfig.output is a Zod schema. undefined when no output schema is configured.

plan?​

optional plan: Plan

Defined in: packages/agentos/src/api/generateText.ts:859

The plan produced by the planning phase when planning is enabled. undefined when planning is disabled or was not requested.

provider​

provider: string

Defined in: packages/agentos/src/api/generateText.ts:784

Provider identifier used for the final run.

providerMessageId?​

optional providerMessageId: string | null

Defined in: packages/agentos/src/api/generateText.ts:825

Provider message id (msg_...) of the LAST agentic step; present only when the run opted in via GenerateTextOptions.cacheDiagnostics. Persist it and pass it back as the next request's cacheDiagnostics.previousMessageId to thread the comparison across turns. null when the provider reported no id.

responseModel?​

optional responseModel: string

Defined in: packages/agentos/src/api/generateText.ts:793

Provider-reported model id of the final step (spec batch-1 C1) — can differ from model across aliases and fallback routing. Undefined on paths where no provider-reported id was captured. model keeps its existing meaning (zero-change).

serviceTier?​

optional serviceTier: string

Defined in: packages/agentos/src/api/generateText.ts:799

Provider-reported service tier the final step actually ran at (OpenAI service_tier on the response; spec batch-1 C2). Undefined on providers/paths without a tier concept.

servingProvider?​

optional servingProvider: string

Defined in: packages/agentos/src/api/generateText.ts:808

Upstream host that actually served the request when provider is an aggregator/router (OpenRouter reports e.g. 'Groq' or 'DeepInfra' per completion). Undefined for direct providers, for aggregators that omit it, and on the prompt-shim tool path. Latency attribution: identical model + token counts vary 3-5x in wall-clock by serving host, so telemetry needs this to interpret durations.

text​

text: string

Defined in: packages/agentos/src/api/generateText.ts:827

Final assistant text after all agentic steps have completed.

toolCalls​

toolCalls: ToolCallRecord[]

Defined in: packages/agentos/src/api/generateText.ts:831

Ordered list of every tool call made during the run.

trace?​

optional trace: AgencyTraceEvent[]

Defined in: packages/agentos/src/api/generateText.ts:849

Structured trace events emitted during the run. Populated by the agency orchestrator; undefined for single-agent calls.

transcriptDelta?​

optional transcriptDelta: SessionTranscriptMessage[]

Defined in: packages/agentos/src/api/generateText.ts:782

Lossless message delta this call appended to the conversation: the request's user turn plus every assistant / tool turn the tool loop recorded, in order, in provider-replayable shape (tool_call ids, parallel results, thinking blocks). Sessions append THIS — never a reconstruction — to their history. Absent only on legacy paths that never seeded a conversation array. The prompt-shim path carries a partial delta (seeded turns only); native providers carry the full trail.

usage​

usage: TokenUsage

Defined in: packages/agentos/src/api/generateText.ts:829

Aggregated token usage across all steps.
