📝 Walkthrough

Walkthrough

Updated AI SDK package versions and aligned provider construction, prompt propagation, response mapping, and stream consumption with the newer SDK API shapes. Tests were updated to match the new request and result fields.

Changes

AI SDK upgrade and API alignment

Layer / File(s)	Summary
Dependency versions package.json	ai and the @ai-sdk/* packages are bumped to newer pinned releases.
Provider wiring src/main/presenter/llmProviderPresenter/aiSdk/providerFactory.ts, test/main/presenter/llmProviderPresenter/aiSdkProviderFactory.test.ts	Gemini uses createGoogle, Bedrock calls provider.embeddingModel(...) and provider.imageModel(...) directly, and the Gemini test iterates result.stream.
Runtime prompt and stream flow src/main/presenter/llmProviderPresenter/aiSdk/runtime.ts, src/main/presenter/llmProviderPresenter/aiSdk/streamAdapter.ts, test/main/presenter/llmProviderPresenter/aiSdkRuntime.test.ts	Leading system messages become instructions, generate and stream calls pass instructions, runAiSdkGenerateText maps reasoning_content and totalUsage from result.finalStep.reasoningText and result.usage, and the runtime tests assert the updated request and result shapes.

Poem

I hopped through the SDK with a twitch of my nose,
New instructions in tow where the old system goes.
Gemini sparkled, Bedrock thumped in the rain,
I streamed every carrot of token and strain.
Thump! The moonlit logs sing: "all green again." 🐰
