@nhtio/adk/batteries/llm/ollama/helpers
Swappable translation helpers for rendering ADK state into native Ollama /api/chat requests.
Remarks
The wire-shape-agnostic helpers (renderUntrustedContent, renderMemories, renderChatCompletionsSystemPrompt, toolsToChatCompletionsTools, …) are shared with the OpenAI battery via the internal ../chat_common/helpers submodule and re-exported here under their original names. Only the Ollama-WIRE-SPECIFIC helpers are defined here: renderOllamaTimelineMessage (flat content + base64 images[] + thinking), renderOllamaToolCallResult (string-only result content), buildOllamaHistory (synthetic assistant.tool_calls with object-form arguments + tool-role messages labelled by tool_name), and ollamaToolsFromTools (alias of the shared tool-definition renderer — native /api/chat uses the same function-tool wire shape).
Native /api/chat supports only base64 images[]; every non-image modality routes through the unsupportedMediaPolicy fallback (stash text / synthetic description) or throws.
Variables
| Variable | Description |
|---|---|
| defaultBuildOllamaHistory | Default native-history assembler; alias of buildOllamaHistory. |
| defaultOllamaToolsFromTools | Default implementation of OllamaHelpers-style tool translation; alias of ollamaToolsFromTools. |
| defaultRenderOllamaTimelineMessage | Default timeline-message renderer; alias of renderOllamaTimelineMessage. |
| defaultRenderOllamaToolCallResult | Default tool-call-result renderer; alias of renderOllamaToolCallResult. |
Functions
| Function | Description |
|---|---|
| buildOllamaHistory | Assembles the complete native Ollama message history for a dispatch — system prompt and content buckets, the interleaved timeline of messages/thoughts/tool calls, and the collected opaque reasoning payloads — by delegating to the injected sub-renderers. |
| ollamaToolsFromTools | Convert ADK tools to the native Ollama tools[] wire. Native /api/chat uses the identical { type: 'function', function: { name, description, parameters } } shape as Chat Completions, so this is an alias of the shared renderer. |
| renderOllamaTimelineMessage | Renders a single timeline @nhtio/adk!Message into a native Ollama message — flattening any media into the base64 images[] array, surfacing reasoning as thinking, and wrapping textual bodies in the appropriate trust envelope. |
| renderOllamaToolCallResult | Render a tool-call result to native Ollama tool-message content (always a string). Media results are routed through the internal media renderer: images cannot ride on a tool-role message's content, so an image result is replaced with a short text marker (the image bytes are not re-sent on a tool message); non-image media use the same fallback-text path as elsewhere. |
