## Summary
- **Configurable agent URL**: All starter `route.ts` files now read
`AGENT_URL` from environment with localhost fallback, enabling
deployment to non-localhost environments without code changes. Applied
to: pydantic-ai, adk, agno, llamaindex, ms-agent-framework-python,
ms-agent-framework-dotnet, crewai-crews.
- **crewai-crews version bump**: Bumped `ag-ui-crewai` from pinned
`==0.1.3` to `>=0.1.5` to pick up the `MethodExecutionFinishedEvent`
dict state fix from ag-ui-protocol/ag-ui#1478.
- **`.env.example` files**: Added `.env.example` with `OPENAI_API_KEY`
and `AGENT_URL` (correct default port per starter) to all affected
starters.
## Starters NOT touched (already configurable or different pattern)
- strands-python (uses `STRANDS_AGENT_URL`)
- langgraph-python / langgraph-js (use `LANGGRAPH_DEPLOYMENT_URL`)
- langgraph-fastapi (has docker-route-override)
- mastra (monolith, no separate agent URL)
## Test plan
- [ ] Verify each starter builds with `next build`
- [ ] Verify `AGENT_URL` env var is respected when set
- [ ] Verify localhost fallback works when `AGENT_URL` is unset
- [ ] Verify crewai-crews agent installs with `ag-ui-crewai>=0.1.5`
The starter pinned ag-ui-crewai==0.1.3 which crashes on crew completion:
'dict' object has no attribute 'messages' in MethodExecutionFinishedEvent
handler. Fixed upstream in ag-ui-protocol/ag-ui#1478, released in 0.1.5.
Every starter's route.ts now reads process.env.AGENT_URL as the
primary agent endpoint, with framework-specific vars as fallback:
- AGENT_URL || "http://localhost:8000" (pydantic-ai, adk, agno, crewai,
ms-agent-python, ms-agent-dotnet, strands-python)
- AGENT_URL || LANGGRAPH_DEPLOYMENT_URL || "http://localhost:8123"
(langgraph-python, langgraph-js)
- AGENT_URL || "http://localhost:9000" (llamaindex)
Also adds .env.example with AGENT_URL to all starters.

creation in classic run(), matching factory run() pattern (M3)
- Add concurrent run guard to classic run() (C1)
- Add threadId/runId to RUN_ERROR events in classic mode (I2)
- Check both 'output' and 'result' property names in classic tool-result (C2/M2)
- Add try/catch around JSON.stringify in classic tool-result (I4/M2)
- Add undefined guards before emitting state snapshot/delta events (I3)
- Guard assignToolsToAgents against factory-mode agent configs (M1)
- Improve error handling in classic error case with proper fallback (C3)
- Improve TanStack converter TODO comment with known gap details (M5)
- Document @ts-expect-error on clone() middlewares access (S1)
- Add JSDoc to AgentFactoryContext.abortController (M4)
- Fix duplicate import and clean up react-router example
- Update docs AgentFactoryContext reference
Finance ERP showcase powered by CopilotKit deep agents. Includes a
Next.js 16 frontend with 7 CopilotKit-registered tools, a LangGraph
multi-agent backend (orchestrator + research/projections subagents),
Postgres-backed dashboard gallery with 12 widget types and 4 templates,
and human-in-the-loop approval flows for invoices and inventory.
Adds a minimal demo at /a2ui-demo that uses the demo-button agent to
reproduce and validate the A2UI thread-clone bug fix. The agent renders
an A2UI surface with a Confirm button on first run; clicking it fires a
second run that emits a text confirmation message.

Attachment queue & previews:
- Image lightbox with View Transition API morph animation
- Video lightbox with native controls and play button overlay
- Document lightbox (PDF via blob URL, text inline, info card fallback)
- Drop zone overlay with upload icon
- Filename preservation via InputContent metadata
- Proper video thumbnail sizing and play/pause indicator
- Fix attachment queue positioning (max-w-3xl constraint)
- Padding between X button and content for audio/document cards
- Document filenames wrap instead of truncating
Attachments config:
- onUploadFailed callback for validation/upload errors (file-too-large, invalid-type, upload-failed)
- onUpload accepts sync or async returns
- AttachmentUploadResult discriminated union with explicit interfaces
- Metadata field on Attachment and onUpload return type
AG-UI version bump:
- Bump @ag-ui/client, @ag-ui/core, @ag-ui/encoder, @ag-ui/proto to 0.0.51
- Remove process.env Vite workaround (fixed upstream in 0.0.51)
Deprecation lifecycle:
- @deprecated JSDoc on all legacy image upload APIs
- ImageRenderer, ImageRendererProps, ImageUpload type, imageUploadsEnabled prop,
inputFileAccept prop, ImageRenderer prop, AIMessage.image, ImageData
- Codemod at codemods/migrate-attachments.ts (15 tests)
- Migration guide updated with codemod instructions and new type shapes
Docs:
- New guide: docs/(root)/multimodal-attachments.mdx
- Updated migration guide with onUpload return type, metadata, codemod section
- Cross-links from prebuilt-components and migration guide
- Label change: "Add photos or files" → "Add attachments"
Tests:
- CopilotChat.attachments.test.tsx — 5 tests for onUploadFailed
- migrate-attachments codemod — 15 tests
Follow-up to #3607 — the same problematic `import { v0_8 } from "@a2ui/lit"`
pattern existed in 4 example files. Switch to `@a2ui/lit/0.8` subpath for value
imports and remove an unused v0_8 import. Also broaden the lint rule glob to
cover `examples/` and prevent regression.

These images were committed as raw binaries on main despite
.gitattributes marking *.png for LFS tracking. Re-add them through
the LFS clean filter so they're stored as pointers.
