- runtime.ts: pass the bridge's forwarded client tools (convertInputToTanStackAI's
tools) into chat() alongside web_search + MCP, so generative-UI cards and the
confirm_write HITL gate work; drop the prompt line that made the model narrate
charts with a trailing "Charting …" sentence (it landed after the image).
- render-chart / render-diagram: post the caption as a header BEFORE the image
(a file upload's message lands a beat after postFile resolves, so caption-first
keeps a stable caption → image order) and drop the false "rendered above" wording.
Depends on the @copilotkit/runtime factory tool-lifecycle fix (#5572) and the
bot-slack HITL/render-order fix (#5573).
The example's runtime agent needed OpenAI's hosted `web_search` tool, but
BuiltInAgent's classic `tools` only accepts handler-based `ToolDefinition[]`
(needs `execute`) — it can't carry a provider/hosted tool. So switch the
agent to BuiltInAgent **factory mode** (`type: "tanstack"`) and drive it with
TanStack AI's `chat()`:
- `openaiText(model)` adapter (OpenAI Responses API; gpt-5.5 default)
- `webSearchTool({ type: "web_search" })` provider tool (`@tanstack/ai-openai/tools`)
- Linear/Notion MCP via `@tanstack/ai-mcp` `createMCPClient` (HTTP + bearer),
created per-run; `chat()` discovers their tools and closes the connections
- `convertInputToTanStackAI(ctx.input)` bridges AG-UI input → `chat()`;
BuiltInAgent converts `chat()`'s stream back to AG-UI events
OpenAI-only now (web search is OpenAI-specific); AGENT_MODEL accepts a bare
OpenAI id or an "openai/<id>" form. Adds @tanstack/ai, @tanstack/ai-openai,
@tanstack/ai-mcp to the example.
100% JSX bot at feature parity with the PoC example: issue/page cards,
tables, Chart.js charts, Mermaid diagrams, incident/status/links cards,
a confirm_write HITL gate, and /agent + /triage slash commands.
