LLMChunk
Interface: LLMChunk
Defined in: src/adapters/types.ts:192
Properties
content
readonlycontent:string
Defined in: src/adapters/types.ts:195
Token text. Empty for the terminal chunk (done: true).
done
readonlydone:boolean
Defined in: src/adapters/types.ts:197
True only for the final chunk in a stream.
response?
readonlyoptionalresponse?:LLMResponse
Defined in: src/adapters/types.ts:210
Authoritative response payload, populated ONLY on the final chunk
(done: true). Carries toolCalls, usage, stopReason — the
fields that drive the ReAct loop. The content mirrors the
concatenation of all non-terminal chunks; consumers can use
either source.
Streaming providers SHOULD populate this. Older providers that
yield only text and end with done: true (no response) are
still supported — Agent falls back to complete() for the
authoritative payload in that case.
thinkingDelta?
readonlyoptionalthinkingDelta?:string
Defined in: src/adapters/types.ts:227
v2.14 — streaming thinking-content tokens. Parallel to content
but for the model's reasoning chain rather than visible output.
Set on chunks that carry thinking deltas (Anthropic emits these
via content_block_delta events with delta.type === 'thinking_delta');
undefined or empty on chunks that carry only visible-content tokens.
Frameworks: this field drives agentfootprint.stream.thinking_delta
events when a ThinkingHandler.parseChunk() returns one. Consumers
who want to render thinking-as-it-streams subscribe to that event.
Default consumer behavior: thinking tokens are not surfaced to end
users unless a consumer explicitly subscribes to the
agentfootprint.stream.thinking_delta event (or renders it through a
live-status strategy).
