chore: add retroactive changesets for PR #411 (AG-UI core interop) by AlemTuzlak · Pull Request #474 · TanStack/ai

AlemTuzlak · 2026-04-20T10:46:03Z

Summary

PR #411 (AG-UI core interop — spec-compliant event types) landed without changesets, so the next release pass would miss the breaking event-shape work. This PR adds them retroactively.

Changesets added

`@tanstack/ai` — major: flat `RunErrorEvent`, `REASONING_*` events, `threadId`/`runId` on `ChatOptions`, `stripToSpecMiddleware` always-last injection, `@ag-ui/core` `EventType` re-export, JSON-Patch `StateDeltaEvent.delta`.
`@tanstack/ai-openai`, `ai-anthropic`, `ai-gemini`, `ai-ollama`, `ai-openrouter`, `ai-grok`, `ai-groq` — patch: emit the new AG-UI-compliant event shapes (REASONING_*, threadId/runId, flat RUN_ERROR). No factory / config-shape changes.
`@tanstack/ai-client` — patch: handle flat `RUN_ERROR`, `REASONING_*`, warn on deprecated `[DONE]` sentinel.
`@tanstack/ai-event-client` — patch: devtools middleware alignment with the new shapes.

No source changes in this PR — only `.changeset/*.md` additions.

Test plan

`pnpm test:sherif` clean
Changeset preview in CI confirms the expected version matrix (core major, adapters/client patch)

Summary by CodeRabbit

New Features
- Added reasoning event types to expose AI model thinking processes separately from step events.
- Introduced thread and run tracking via optional threadId and runId parameters.
- Enhanced tool call events with improved naming properties.
Improvements
- Standardized event shapes across all adapters to align with AG-UI specifications.
- Simplified error event structure with flattened payload format.
- Added automatic event normalization middleware to ensure spec compliance.

The original PR was merged without changesets. This adds retroactive changesets so the release pipeline picks up the breaking event-shape work across core, adapters, client, and event-client. - @tanstack/ai: major (flat RunErrorEvent, REASONING_* events, threadId/runId, strip-to-spec middleware, AG-UI core EventType re-export, JSON-patch StateDelta) - All provider adapters (openai, anthropic, gemini, ollama, openrouter, grok, groq): patch — emit AG-UI-compliant shapes; no public API change - @tanstack/ai-client: patch — consumer side of the new event shapes - @tanstack/ai-event-client: patch — devtools middleware alignment

📝 Walkthrough

Walkthrough

Four changeset files document AG-UI core interoperability updates across TanStack AI packages, including event shape standardization, new reasoning event types, modified error structures, thread/run tracking via threadId/runId, and a new stripToSpecMiddleware to normalize events to AG-UI compliance.

Changes

Cohort / File(s)	Summary
Adapter Packages `.changeset/agui-core-interop-adapters.md`	Patch release for OpenAI, Anthropic, Gemini, Ollama, OpenRouter, Grok, and Groq adapters to align stream output with AG-UI event shapes, emit `REASONING_*` events, propagate `threadId`/`runId`, and flatten `RunErrorEvent` structure.
Core AI Package `.changeset/agui-core-interop-ai.md`	Major release for `@tanstack/ai` introducing AG-UI spec alignment: `StreamChunk` reuses `@ag-ui/coreEventType`; `RunErrorEvent` flattened to `{ message, code }`; `REASONING_` events added alongside `STEP_`; tool calls expose `toolCallName`; `ChatOptions` gains `threadId`/`runId`; `TOOL_CALL_RESULT` emitted post-execution; new `stripToSpecMiddleware` removes non-spec fields; `StateDeltaEvent.delta` becomes JSON Patch array.
Client Packages `.changeset/agui-core-interop-client.md`, `.changeset/agui-core-interop-event-client.md`	Patch releases for `@tanstack/ai-client` and `@tanstack/ai-event-client` to route AG-UI-compliant event shapes, handle flat `RUN_ERROR`, consume `REASONING_*` events, and update devtools middleware instrumentation.

Poem

🐰 A chorus of changelogs hops into spring,
AG-UI now speaks through each streaming thing,
Reasoning blooms where steps used to tread,
Events laid flat, no nests to dread,
IDs thread through, from start until end! ✨

🚥 Pre-merge checks | ✅ 3

✅ Passed checks (3 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title accurately and concisely describes the main change: retroactive addition of changesets for PR `#411`, which addresses AG-UI core interop. It is specific and clearly summarizes the primary change.
Description check	✅ Passed	The description includes a comprehensive Summary section detailing why the changesets are needed, lists all four changesets with their versions and key changes, and documents testing (test:sherif passed; CI preview pending). The description mostly follows the spirit of the template by explaining the changes and noting the changeset addition, though it does not explicitly check off the template checklist boxes.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
