Interface: OllamaHelpers ​

Defined in: src/batteries/llm/ollama/types.ts:275

Full translation-helper contract for the native Ollama battery. Extends the wire-shape-agnostic ChatHelpersCommon (shared with the OpenAI battery) and adds the Ollama-WIRE-SPECIFIC members: flat timeline-message rendering (images[] + thinking), string-only tool-call-result rendering, and native-history assembly (tool_name, object-form tool-call arguments). There is no streaming tool-call delta accumulator — native /api/chat emits whole tool_calls per chunk.

Remarks Optional override seam. When omitted the battery uses the shared defaultRenderArtifactHandleBody. A consumer overrides it to change WHICH reader the model is steered toward first — e.g. promoting the JSON content-readers (artifact_json_get / artifact_json_keys) ahead of the metadata-only artifact_json_type for a small model that grabs the first listed tool.
